Oil cooler gasket

1
Hi all,

Anybody got any tips or info for me before I attempt to replace the "o-ring/gasket" between the oil cooler and the engine...

Two things come to mind....

Should I use a sealant and if so which one??
What sort of tension do I do the central nut up too??

Any info would be apreciated

Cheers Tony

Make sure that you buy the correct O ring. Don't just use an oil filter gasket.

Replace the 2 water hoses. They are cheap and prone to failure.

Good luck, it's a crap job.

Tony,
All you need do is clean the mating surfaces thoroughly before attaching the special O ring as the one shown in attached pic. No need to overdo the tightening of the oil cooler retaining nut.
From memory, the skid-rail fastening bolt immediately adjacent to the oil cooler is unnecessarily too long and impedes the removal/installation process of the oil cooler. You have to remove this bolt first anyway so while it's out, reduce its length such so as to achieve two things ... still able to fasten the skid rail correctly plus enable the oil cooler to be removed/reinstalled more simply in the future without the necessity to remove this bolt.
Cheers.

Ken,

In your advice regarding the fitting of the oil cooler O-ring you said to ensure the two faces are clean but there was no mention of using any sealant.. I am reading in the Haynes manual to coat both faces with sealent (VW type AMV 18810102 or equivalent)

So I guess my question is...

Do you use any sealant??

I really don't want to have to perform this operation twice...

Cheers mate

Tony,
It says also in Bentleys to coat mating faces with the same sealant, so I guess you better. I missed applying the sealant with my new cooler and O-Ring  :-(( ... but no leaks to date. Touch wood?

I am just picking up on this thread.  Given that the oil pressure in most petrol engines is actually on the low side, in that it is designed to provide high flow rates at relatively pressure, I have never used sealant on an oil filter.  All that I do is ensure that the surfaces are clean and free of damage or distortion, lubricate the O ring well with engine oil and screw it on.  I have never had a problem with leaks.  Some of our hands-on members might be able to comment further on that.

My query was about using a sealant between the oil cooler and motor...I am hoping to fix a leaking O-ring.

As far as the filter, I do exactly what you have described..

Tony,

Greg Esposito should have something definitive to say when he comes on line.  If the mating surfaces are clean and free of damage, it should not need anything more than the O ring but let’s see what some of out hands-on people can add.

I would use, sparingly, a very high quality black silicone ( Like Toyota's, or The Right Stuff ) on a tired oil cooler o-ring seal,
And make sure the oil cooler nut is well tightened of course.

one trick on installing a spin-on oil filer is make darn sure the rubber seal comes off with the old oil filter.
Once in a great while....the old one will stay stuck on the engine ..
the tech doesn't notice, the OF goes on with two rubber seals..
and about 50 miles later all the oil gets pumped out onto the ground ..ruining the engine. It's happened.

I pre-fill my waterboxer oil filters..
just be extra careful as you are adding oil to the unfiltered, engine bearings, side of the filter element .

I use a new, correct o/ring with no sealant. Not that a light smear is not o.k. I just find that if the cooler moves after the sealant cures they leak. The thing to note is that these o/rings were revised to add those locating tangs. In my experience what happens is that after some time the o/ring is compressed and the oil filter ends up holding the tension for the cooler. When the oil filter is removed the nut is loose and the cooler turns and moves.

I would use, sparingly, a very high quality black silicone ( Like Toyota's, or The Right Stuff ) on a tired oil cooler o-ring seal,
And make sure the oil cooler nut is well tightened of course.

one trick on installing a spin-on oil filer is make darn sure the rubber seal comes off with the old oil filter.
Once in a great while....the old one will stay stuck on the engine ..
the tech doesn't notice, the OF goes on with two rubber seals..
and about 50 miles later all the oil gets pumped out onto the ground ..ruining the engine. It's happened.

I pre-fill my waterboxer oil filters..
just be extra careful as you are adding oil to the unfiltered, engine bearings, side of the filter element .

I am just picking up on this thread.  Given that the oil pressure in most petrol engines is actually on the low side, in that it is designed to provide high flow rates at relatively pressure, I have never used sealant on an oil filter.  All that I do is ensure that the surfaces are clean and free of damage or distortion, lubricate the O ring well with engine oil and screw it on.  I have never had a problem with leaks.  Some of our hands-on members might be able to comment further on that.

Ken,

In your advice regarding the fitting of the oil cooler O-ring you said to ensure the two faces are clean but there was no mention of using any sealant.. I am reading in the Haynes manual to coat both faces with sealent (VW type AMV 18810102 or equivalent)

So I guess my question is...

Do you use any sealant??

I really don't want to have to perform this operation twice...

Tony,
All you need do is clean the mating surfaces thoroughly before attaching the special O ring as the one shown in attached pic. No need to overdo the tightening of the oil cooler retaining nut.
From memory, the skid-rail fastening bolt immediately adjacent to the oil cooler is unnecessarily too long and impedes the removal/installation process of the oil cooler. You have to remove this bolt first anyway so while it's out, reduce its length such so as to achieve two things ... still able to fasten the skid rail correctly plus enable the oil cooler to be removed/reinstalled more simply in the future without the necessity to remove this bolt.

Hi all,

Anybody got any tips or info for me before I attempt to replace the "o-ring/gasket" between the oil cooler and the engine...

Two things come to mind....

Should I use a sealant and if so which one??
What sort of tension do I do the central nut up too??

Any info would be apreciated

Tony,

When I R&R'd my water pump, I SPARINGLY used Permatex "Ultra Copper" on the O-Ring seal. It's expensive, probably because it has multiple uses compared to other single use Permatex products. It keeps well in the tube for the next repair job such as the oil cooler O-Ring procedure you are about to embark on, so long as you replace the cap tight and add some gladwrap first. Too bad I neglected to use it on mine!! Go sparingly though, you don't want sealant coming loose internally and migrating through your engine oil system.


Surf through Permatex auto gasketing products from here: http://www.permatex.com/products/Automotive/automotive_gasketing.htm

Enjoy. I know you will! HA!

It only started leaking after I did an oil change... Maybe I have loosened the nut and caused the leak.. Do you think I may get away with removing the filter and just tightening the nut to stop the leak??

I use a new, correct o/ring with no sealant. Not that a light smear is not o.k. I just find that if the cooler moves after the sealant cures they leak. The thing to note is that these o/rings were revised to add those locating tangs.

I would not consider it advisable. The o/ring is probably hard and compressed. I would buy a new o/ring and the two coolant hose elbows ( just as Phill said ) and get your hands dirty. Check the cooler for pitting at the pipes also. Greg

Tony,

If you pull the oil cooler, there may be a date-stamp imprinted on its exterior. Mine was marked 1989. Given my van was built in late 1989, suggests it was still the original cooler. I found the state of the O-Ring to be flattened and quite hard, nothing like it should be and no sign of any sealant. I found a build up of thick yucky gooey oily crud oozed slowly from the oil coolers inner oil galleries!!! Made me wonder when the oil is changed, does the oil cooler drain out fully!!! I suggest in such a scenario .... toss it and fit a new cooler!

You may drop some coolant in the process. If your coolant is in good condition at the moment, collect what drops into a bucket and reinstall it later through any filter material, just to be sure.

If you elect to reuse the existing oil cooler (after checking the internal galleries for cleanliness and functionality) but there is pitting to the two spiggots that the rubber hoses fit to, wire brush/clean them thoroughly then repair the pits ... fill/cure/sandpaper them with JB Weld, available in a blister pack at Jaycar or Bursons. A perfect product for this issue. I also painted (POR15) the spiggots to stop the re-occurrence of the pitting.


If uncertain what to do for the best, replace the cooler,its O-Ring and the mini rubber hoses while things are dismantled/removed.

Cheers.

Ken

To all who have offered advice, I say a huge thank you...

I guess I'll tackle it tomorrow....

Tony,

If you pull the oil cooler, there may be a date-stamp imprinted on its exterior. Mine was marked 1989. Given my van was built in late 1989, suggests it was still the original cooler. I found the state of the O-Ring to be flattened and quite hard, nothing like it should be and no sign of any sealant. I found a build up of thick yucky gooey oily crud oozed slowly from the oil coolers inner oil galleries!!! Made me wonder when the oil is changed, does the oil cooler drain out fully!!! I suggest in such a scenario .... toss it and fit a new cooler!

You may drop some coolant in the process. If your coolant is in good condition at the moment, collect what drops into a bucket and reinstall it later through any filter material, just to be sure.

If you elect to reuse the existing oil cooler (after checking the internal galleries for cleanliness and functionality) but there is pitting to the two spiggots that the rubber hoses fit to, wire brush/clean them thoroughly then repair the pits ... fill/cure/sandpaper them with JB Weld, available in a blister pack at Jaycar or Bursons. A perfect product for this issue. I also painted (POR15) the spiggots to stop the re-occurrence of the pitting.


If uncertain what to do for the best, replace the cooler,its O-Ring and the mini rubber hoses while things are dismantled/removed.

Cheers.

Ken

Greg,

It only started leaking after I did an oil change... Maybe I have loosened the nut and caused the leak.. Do you think I may get away with removing the filter and just tightening the nut to stop the leak??

I use a new, correct o/ring with no sealant. Not that a light smear is not o.k. I just find that if the cooler moves after the sealant cures they leak. The thing to note is that these o/rings were revised to add those locating tangs. In my experience what happens is that after some time the o/ring is compressed and the oil filter ends up holding the tension for the cooler. When the oil filter is removed the nut is loose and the cooler turns and moves. Depending on the condition of the o/ring and the amount of grit in the area and if the tech tightens the nut the o/ring may leak. I have also seen these o/rings spring a leak when ambient temps get low. So I would say best advise would be a light smear or not just be sure to recheck the nut every filter change (without over tightening). Greg E

I would use, sparingly, a very high quality black silicone ( Like Toyota's, or The Right Stuff ) on a tired oil cooler o-ring seal,
And make sure the oil cooler nut is well tightened of course.

one trick on installing a spin-on oil filer is make darn sure the rubber seal comes off with the old oil filter.
Once in a great while....the old one will stay stuck on the engine ..
the tech doesn't notice, the OF goes on with two rubber seals..
and about 50 miles later all the oil gets pumped out onto the ground ..ruining the engine. It's happened.

I pre-fill my waterboxer oil filters..
just be extra careful as you are adding oil to the unfiltered, engine bearings, side of the filter element .

I am just picking up on this thread.  Given that the oil pressure in most petrol engines is actually on the low side, in that it is designed to provide high flow rates at relatively pressure, I have never used sealant on an oil filter.  All that I do is ensure that the surfaces are clean and free of damage or distortion, lubricate the O ring well with engine oil and screw it on.  I have never had a problem with leaks.  Some of our hands-on members might be able to comment further on that.

Tony,
It says also in Bentleys to coat mating faces with the same sealant, so I guess you better. I missed applying the sealant with my new cooler and O-Ring  :-(( ... but no leaks to date. Touch wood?

Ken,

In your advice regarding the fitting of the oil cooler O-ring you said to ensure the two faces are clean but there was no mention of using any sealant.. I am reading in the Haynes manual to coat both faces with sealent (VW type AMV 18810102 or equivalent)

So I guess my question is...

Do you use any sealant??

I really don't want to have to perform this operation twice...

Cheers mate

Tony

Tony,
All you need do is clean the mating surfaces thoroughly before attaching the special O ring as the one shown in attached pic. No need to overdo the tightening of the oil cooler retaining nut.
From memory, the skid-rail fastening bolt immediately adjacent to the oil cooler is unnecessarily too long and impedes the removal/installation process of the oil cooler. You have to remove this bolt first anyway so while it's out, reduce its length such so as to achieve two things ... still able to fasten the skid rail correctly plus enable the oil cooler to be removed/reinstalled more simply in the future without the necessity to remove this bolt.
Cheers.

Hi all,

Anybody got any tips or info for me before I attempt to replace the "o-ring/gasket" between the oil cooler and the engine...

Two things come to mind....

Should I use a sealant and if so which one??
What sort of tension do I do the central nut up too??

Any info would be apreciated

Cheers Tony

Ken, did your original oil cooler O-ring have the two location tabs?
Mine didn't, so I thought that some dodgy mechanic had used an oil filter gasket. It was as hard as metal.

I have been told not to re-use drained coolant due to aeration. Whether it matters or not really??????

If you clamp the hoses off, you loose very little coolant.

I think that if there is corrosion pitting on the cooler pipes that I would replace the cooler as it could be corroded internally.
