OIL LEAK
My M38 leaks at one oil pan bolt. It drips a few drops after shut off. I initally thought it was my fuel pump. I did tighten a bit. I am OK changing the entire gasket but wanted to know of there is a fix to this without changing the gasket. It looks like the oil is coming from around the bolt itself and not from where it meets the block.
Thanks, John

Re: OIL LEAK
Which one is it? Remove it and coat the threads with Permatex #2 or #3.

Re: OIL LEAK
Ok, I will try that. I believe its the 1st or 2nd bolt rounding the corner from the front, right above the oil drain plug. Thanks, John

Re: OIL LEAK
All oil pan bolts, and any bolt that penetrates either oil or water containers, must be thread sealed with permeated. It smells good too. I apply it with my fingers.

Re: OIL LEAK
Permatex sealers were used by Willys for the various sealant requirements and are noted in the Willys list of Vendors contributing to Jeep production. Permatex 1, 2, and 3 are still sold today and just as effective as they were back in WWII.

Re: OIL LEAK
Besides what has been mentioned these compounds work considerably better added when/while the area is 'clean' & no oil is present.
Often folk try to stop an oil leak by zealously overtightening the securing bolts.
This action distorts the oil pan & potentially damages the gasket, compounding the leak issue.
On an oil pan [sump] the securing bolts often have thicker, wider & in some cases rectangular flat washers to spread the securing force/load over a larger area & not distort the oil pan hole/s.

Re: OIL LEAK
Thank you all for the advice. I used some permatex thread sealant on the threads and around the small lockwasher and no leaks. Have a great Memorial Day weekend. John

Permatex, Model T technology, still going strong.
