Hey guys! Donny, here, once AGAIN, lol. I have a 1990 f150 shortwide, with a 302 and AOD in it. I have replaced the belts, hoses, thermostat, water pump, and timing chain cover 4 times, and it STILL leaks, and I can't find it! It appears to be leaking around the harmonic balancer, but ALL of the gaskets and seals are brand new, a few times over! any ideas? I KNOW some of you have dealt with this.

Look at the cylinder head/intake manifold joint. My 302 leaked from there and I thought it was the timing cover too. I only found it by pressurizing the system and using a mirror to get a view of it.

yeah, I did, and what I found out today, after extensive cleaning of my timing covers(I had some old ones laying around) they are ALL cracked in various places, and frankly, I don't get how they didn't leak long before this! I ordered a new timing cover, and I bought a new gasket set, and when my new cover comes in I orter be in good shape.
