Thread: Serious oil filter adapter problems

Tweet

First off I want to thank all of you for your useful support and info.Sure enough because I couldn't see it the O-ring wasn't seated properly.Once I got it apart one side of the O-ring was caught or blew-out leaving the adapter bolts barely finger tight.I got me to thinking.Compare the size of O-ring to the rubber gasket on the oil filter. Well that is a no brainier.The phooey size of O-ring size just doesn't compare.Likely the reason why the leak over the long term.I am not one to give up on a mechanical challenge,but if it doesn't make sense in a bad design then what's the sense in trying to get over that and risk a engine to boot.

So I did a oil cooler delete unscrewing the threaded center with I think it was a 10mm Allen socket and screwing it back on the block and then just reattaching the oil filter.I think I got it now.I ran it until at operating temps while it was still on the jackstands and the oil filter was dry.The truck is so soaked in oil that it has drips for now.So I will be driving by dipstick for now until I figure a way to take it to a coin car wash and clean the bottom without taking a bath in water/oil.

Now I don't know how the aftermarket oil cooler adapters are.Hopefully they have a wider rubber gasket than the ones that where built by GM with that dumb O-ring.I would think that small of a O-ring wouldn't fair well with a high pressure oil pump.

Hey Jerry or Pat-could you machine the groove wider on these GM adapters so they would end up with a rubber gasket in size similar to the wide flat rubber gasket on oil filters??.
