I guess I'm ahead of you. I fired mine off this morning and it runs great. The only problem was that after it warmed up, major oil pan leak. I tried eliminating the gasket and just using Right Stuff and I guess I did not use enough. Leaked like crazy. I then attempted an "in the car" gasket install. Absolute horror! The main studs would not allow the pan to be removed without lifting the engine. I cleaned and reinstalled the pan with the silicone and it still leaks some. I'm going to pull the engine out of the bay slightly this week and do it right. I will never do an in car oil pan again. I can pull the engine and do it right with just about the same amount of work.

Did you get the blue pan gasket? Check the pan rails for straightness?

I have the Cometic cork on order. My pan is probably tweaked. I had to "clearance" it with a big hammer. The rear main studs were hitting the pan. I didn't use a gasket, just the Right Stuff....twice! It only leaked the second time from around two bolts. I might try to remove the bolts and just shoot some silicone into the holes to see that works. I really not sweating it. Even if I have to pull the engine again, no big deal. I'm just glad the small leak is the only issue.

Question....Are the oils pans for the NA 231 the same as the LC2 pans?

 

[GBGN1]

Oil pans are the same. Yes , I did the same with the silicone . But I laid it on thick. Hopefully it doesn't leak. My studs never hit the pan

Thanks....I'm going to get another pan and give it another try in a couple of days.
