Stopping an oil leak from a oil filter sandwich plate (with gasket)
Hey guys
Can anyone recommend a way of stopping an oil leak between an oil filter sandwich plate and the engine block (gasket in between)?
I'm planning on taking my daily driver (1990 Eunos Roadster) on a track day or two, so have gauges for oil pressure, oil temperature and water
temperature.
The oil temperature and pressure readings come from a sandwich plate fitted between the block and the oil filter. I fitted the plate, making sure that
the gasket between the plate and the block was seated correctly (also applied a little oil to the face of the gasket that meets the block). Re-fitted
the oil filter, left it running for a while then took it for a drive. Came back and oil was leaking from the gasket- for now I've just taken the
whole arrangement off and put the filter back on.
Is there anything I can do to stop the leak, should I be using liquid gasket between the plate and the block? Someone recommended dropping the gasket
in some boiling water and letting it cool, the idea being it will soften the rubber- but I'm not sure whether that'll work?
Any suggestions?
Thanks in advance all,
Ben.

loctite bule instant gasket
nice simple fix, i did it on my sand plate on my nissan engine, leaked like a bp oil disaster with the o-ring in place, so took out the o-ring and
replaced with the instant gasket, no more leak

Blue Hylomar
Use Blue Hylomar on each surface.
Link here: Blue Hylomar
I have used this in a number of engine rebuilds over the last thirty years+ and it has never failed me once.

Is the sandwich plate completely flat on both sides? I had an oil filter housing which leaked and it was just due to the fact that it had a
manufacturing fault. Sent it back and it was re-done, then no problem.
If you have just bought it I would check with the manufacturer.

Thanks so far for the replies, I was going to use liquid gasket and my next question was which one to use!
In terms of the sandwich plate, it has an engraved section for the gasket to sit within- the gasket has two raised ridges that locate it into the
plate- so it's not a simple o-ring:
I have a feeling replacing the whole thing with liquid gasket wouldn't be effective- I'm thinking liquid gasket on both sides of a
properly cleaned gasket and sandwich plate should do it?

Give Blue Hylomar a try. You will not be
disappointed. You do need to coat each surface.
In your case, coat the block, each side of the gasket and the mating face of the sandwich plate.
The best part of it is that it is non-setting. If you need to dismantle the part at a future date, it all comes away easily and without damage, even
to the gasket itself. At least, that has been my experience of using the stuff.

Hi
Personally i wouldn't introduce hylomar anywhere near the oil system.
IS the gasket being use the correct one IE the wide face and not a cheap version IE like whats on an oil filter as in narrow width.

Hey Matt - the gasket looks pretty heavy duty, it's definately wider and thicker in construction than a normal oil filter o-ring. I'm
wondering if a couple of heat cycles whilst it was on have caused it to expand and shrink enough to let some oil through...

those double o-ring fat washer setups are shit, throw it in the bin and get 1 o-ring to fit the smaller size groove and fill the bigger groove with
the instant gasket, I did this on mine and it was fine afterwards
