Man what some great advice on these posts

Awesome - Thanx guys


What is the proper way to re install the harmonic balancer ??? Pull into back on the crank

I used a steering wheel puller to take it off , worked slick

a damper installation tool threads into the crank snout threads, then a nut and washer is used to pull the damper home. this keeps from pulling or messing up the crank threads out of the end of the crank. a tool for this can be bought or fabbed up if you have the means to do so.

Perfection !!!

Once I got the 45 year old timing chain cover all cleaned up , gasket off , bead blasted and paint removed , it was obvious

Passenger side locater pin hole on cover was bent out


That locater hole was protruded out like it grabbed the pin on block and didn't set proper or I had to pound it on many many years ago when I replaced a wiped out cam on a newly rebuilt motor from what I can remember.
Man that was a long time ago

Anyways over time , especially as of late , leak got progressively worse and kept following the profile of the passenger side oil pan gaskets making it look like it was leaking everywhere

Smoothed out the cover , made sure both locater pins where paint free , cleaned up the holes just slightly with a drill bit like mentioned THANX !

Greg At Superformance supplied all my gaskets and seals
Awesome Customer Service !!!

Installed the timing chain cover dry like he mentioned , gasket is a little thicker then your typical fel pro

Superformance oil pan gaskets

Not a drip - Gotta love a leak free motor after a few rides

Just disappointed in myself assuming it was the oil pan gaskets all this time - Yes I had to replace the rear main seal - I wanted to replace the beat up factory 402 oil pan anyways , but wasn't planning on pulling it three times - Was about to buy a reproduction timing chain cover , however the original one ended up looking brand new when all fixed and cleaned up

THANX GUYS !!!

thanks for the update and glad you nailed it

bee1971 it was great talking with you as well

Glad you found the culprit of your leak.

BTW that's how a motor should look and stay looking! Very nice!
