What is the proper way to put in a paper oil pan gasket? Use copper washers on the bolts? Use Permatex #2? Use Permatex #2 on both sides of the gasket?
I don't use washers, and I use the black RTV that is high oil resistant ( I think there's a "weaker" version too?) and smear a thin film on both surfaces. Learnt from my expert engine guy to then wait overnight before adding the oil, as the RTV needs time to cure.
I've gone to using Hi-Tac aircraft gasket sealer. It seals real good and is easy to dissemble parts. You just brush it on and assemble. It also holds gaskets in place for assembly. It's made by Permatex.
Ignacio before you reinstall your oil pan with a new gasket make sure its flat all the way around.
T oil pans tend to dimple inward in the bolt holes after years of tightening and retightening.
Clean up the oil pan and then lay it on a flat surface and flatten out the bolt holes with a hammer.
If you don't do this it will still leak no matter how much sealer you put on the gasket and try to tighten it up, add rubber washers and etc.
Are you talking about the inspection pan or the complete pan? if the inspection pan what has been stated is adequate. If the complete pan it should be straightened on a pan straightening jig.
Inspection pan only. I am not yet skilled enough to do a complete engine tear down. I am just doing a simple refresh not a tear down.
John is right on the money. Straighten that inspection cover. :-)
I might venture a guess to use the sealant you have on the bottom side of the gasket only. Perhaps leave the top or the block side bare so it'll come apart easier later on. Then theoretically, the gasket comes off with the oil pan/inspection cover. Ooh, maybe a light coat of grease on the top side of the gasket?
Shoot, if you want no leaks at all, clean all pieces and slime that gasket on both sides and bolt it up.
Copper washers? Yes, use them if you have 'em already. If you don't, the sealant will do it real nice on the bolts.
Personally, I'd really like a report after some run time to see if they leak at all.
That's on one of my to-do lists. Rod cap filing and oil leak stop on the inspection cover bolts. My '18 (with a '23 engine) is a real drip, the '19 engine that hasn't been opened up for 70 years down there hardly leaks at all.
I drove mine to the firestation monday night. Parke and got out. One of the guys said " I cant believe that thing dont leak oil". I had just steped off the running board. I said give it a minute if it doesnt drip I need to put oil in it. It dripped and oil was fine!
Ultra black, and 5/16" Dorman copper washers. Almost never a leak.
Inspection plate is in! On to the head!
