Who hasn't dealt with this issue, especially pulling the motor apart many times.  I really like the remflex gaskets.  I was having issues with leakage on the up pipe and I did try different sealants.  But the remflex works great, just don't over torque.

Thicker gaskets are an invitation to the exhaust gases to burn a trench to freedom across the mating surface-especially when the egts are optimized up around 1700 degs.

I almost feel back to gaskets seeing Earl sells them on Ebay even after his post on just RTV.LOL Earl almost got me. Iím looking for the RTV of choice.

Don't get the oil pan gasket either. 


  Those are the only two things I have on my page that I don't recommend.


...oh, and Delco plugs.   Always go with NGK.  :)


(and it's a shame I mail out over 10 sets of Delcos for every one set of NGKs)

I've noticed that some modern engines don't use gaskets as they are usually the weak spots in the assembly.  Rather they use various formulations of rtvs.

I'm sure that Earl will catch flak for his use of Rightstuff to seal an oil pan to the block, but, I doubt he plans on removing the pan any more frequently than a manufacturer does and the elimination of leaks overrides the extra effort required on removing the pan somewhere in the future.

The average car nut is mired in the past.  If "it worked 50 years ago, why should I change" mentality

Oh, I've caught all kinds of shit over it. 

   Luckily for me, I've removed my pans quite a few times before I learned from the internet experts that I couldn't do it.


   But neither my Buick or my 454 jetboat leaks oil (and my pickup depths are set to the correct curtain area), so what do I know?

check a few and see if they are still where you put them.  Just in case you have some bolts that have stretched and gotten soft with age...like me
