Looking for thoughts on sealer for the front of the pan. I know I should not need it but I am out of other ideas. Original oil pan and timing cover. They seem to be undamaged. Current pan gasket is the correct for early style pan one piece (I tried with the original style gaskets twice) but I continue to have a small but constant drip between the lip of the pan and the timing cover. Any help would be appreciated.

Re: 62 Oil Leak
John,
Are you sure the leak is not the crankshaft seal in the timing cover?
If it is the pan it may take a substantial amount of silicon sealer to make a good seal. Even if the timing cover and pan seem to be in good condition they can be bent enough to cause problems. I have had an engine before that required a lot of sealer on the front pan seal even though they looked good.
Excessive blow-bye can cause oil to be forced passed gaskets.

Re: 62 Oil Leak
agree with verle. i'd remove the harmonic balance and install a fel-pro sleeve on the balancer--they are readily available. if the balancer/timing chain cover seal is the source of the leak, the fel-pro sleeve will cure the problem. mikeComment

Re: 62 Oil Leak
John....if you do remove the harmonic balancer, look it over very closely. I've seen more than one with a crack in the keyway.Comment

John------
Also, if you remove the balancer to install a sleeve make sure that you do the following:
1) install the sleeve 100% "straight-and-true". If it "cocks" in any way when you install it, then you must remove it and start over again WITH A NEW SLEEVE;
2) use Loctite sleeve locking compound on the interface between the balancer snout and the sleeve;
3) apply a daub of Permatex Ultra Copper or Ultra Black RTV sealer to the keyway of the balancer before installation. The keyway is a notorious source for a leak path which most folks don't consider. As a matter of fact, GM eliminated the keyway on Gen II small blocks for this very reason.In Appreciation of John HinckleyComment

Re: 62 Oil Leak
John,
before taking anything apart you could add oil leak tracer dye ( AC Delco pt. #10-5003) to the oil. The dye makes the oil glow green-yellow under UV light and will show you the source of the oil leak.Comment
