Mep802a oil pressure relief repairr

[CDR]

If you followed my previous post I have a over oil pressure with my generator the pressure goes over 180 PS I and holds the valves open so the motor does not run

So I took the plunge today and opened up the crank case I found lots of rust everywhere. I located and removed the oil pressure relief valve. It was extremely easy to disassemble it was corroded and filled with rust and stuck closed.

A quick cleaning and re-oil and works perfectly. I did not have a new gasket I attempted to reuse the old one which on start up oil came out from all over.

This is extremely easy to fix so if you're having this issue don't be afraid to tackle it.


So I think it's been asked for where is everyone find their parts from?

Here is the engine gasket set. Should include EVERY gasket on the engine. I am looking for a surplus lot of them somewhere, but my membership at NSNnow has expired. I suggest signing up fro a trial over there and typing in the NSN number, and finding places that have them NOS and request a quote via email.

glad you fixed it, given the high cost. if it was full of rust, what about the rest of the lube system? wouldn't junk have gone to all the bearings etc?
it certainly would be easy to just make a gasket

Everything was a little rusty in there connecting rods crank and the block. Following the oil galley path it looks like it goes threw the filter first so I'm not that worried about the bearings. I made tons of gaskets for stuff this would be a harder one to make it's involved and full oil pressure is against it. I order one from Kraft power I hope it's the right one.
