Rebuilt an engine for my wife's 1971 AMC Javelin SST with a 360 in it.

Everything is GREAT (never heard an engine sound so good) except what I originally thought was a slight oil leak from passenger-side head - is actually antifreeze.

An engine shop did the head work - not me.

Any ideas what would cause this?
Incorrectly torqued bolts?
Boogered gasket?
Cracked Head?
Cracked block?

I would think the shop checked the block and heads for any cracks.
They hot-dipped the block, installed the cam, crank, and heads for me since they had it.

We added the intake, fuel pump, etc.

Any ideas? Confirm or deny any of my suspicions.

got a pressure tester? if so, use it and see if you can pinpoint leak any better. or get some stop leak and try it.

I used RTV sealant and a gasket. It is definitely NOT the intake.

You can see it leaking from the front of the head. No question about it.

Torque is supposed to be 105-110 ft lbs.
We just checked them and they are at 50 ft-lbs.

Never dawned on me to double-check them before hand. Live and learn.

Either way, I hope it solves my problem.

Any other suggestions, please let me know. I appreciate hearing everybody's feedback.

Oh...... I forgot........ just to clarify, the shop bored the cylinders .030 over.
New pistons too.

Alot of stuff to list.... so I'll skip it but if anything is pertinent, ask me and I'll tell you.

Yes, it only leaked while running and warm. It does not leak while sitting.

I'll work on the picture(s). It needs some 1/4 panel work and a new paint job.........

We re-torqued the bolts last night (drop the header, pull valve cover, re-torque, put everything back).

By the time we had done that, it was dark (I like DST better) so we wrapped it up.

While I'm at work, I'll have Dad start it and test it.

The Javelin is at his house. The 70-1/2 Falcon (Torino) is at my house.

I'll work on pics on the Torino too........ I haven't even started to remod it yet.
