Hello.

I joined the forums to ask about a leak I can't figure out.

____

My 360 FE:
Stock Rebuilt - 12 months ago - stock
.030 over [just for clean-up]
76 AA heads [for valve seats]
Edelbrock 390 Performer - Holley 4-barrel - Headers [for airflow]
Stock cam / Crank - Not a hot-rod

____

I could really use some help with my 360 oil leak.

I pulled my 360 and put it on my test stand.

It appears as if oil [anti-freeze?] is coming up through the head bolt?

It leaks, from what seems to be the head bolt, then runs through the headers and down the block.

The head bolt between 3-4 / 7-8 appears to be the worst.

I have some pictures on photobucket:

Thank you very much for your help.

i know on a sbf you have to use sealer on the bottom head bolts to keep water from leaking. maybe its the same way on that motor

Can't tell much from those pictures.Is it possible that it is leaking from the valve cover and running down the head into the bolt area?.I would spray some brake clean all over it and clean it up really good.Then run it a bit and inspect.

I think that only applies to 5.0s
