Bought a short block from TRE performance...took 2 full days to get motor into the 65. Started it up and oil is pouring out the rear dripping down the beel housing...did these bastards not install a galley plug or maybe even the rear main seal? Now I have to spend a full day pulling it out, and then another putting it back in again. What else could have been forgotten? I am beyond pissed. Everytime I rely on someone elses work I get ****ed.

 

Is it possible that you got a rear intake manifold oil leak?
I've replaced several intakes in the past doing 4V upgrades and I've also taken a couple back off because a oil leak you mentioned.

That was when I got smart and started studding my 4 corners of the manifold so that I knew 100% it dropped straight down and never shifted and moving gaskets while placing it on.

I'd look into that before taking the whole motor out.

yes, sounds like you got a bad rear main seal probably.. a galley plug left out would leak a ton of oil.

good, idea with the intake studs. I like to put a stud in the center of each head, then pull them out once you got the rest of the bolts in.

 

He mentions it dripping down the bell housing, so I was more inclined to the intake manifold.

Depending on how long the short block sat before it was sold, the rear seal could possibly have dry rotted a bit causing the leak.

There is a large press in plug in the lifter valley near the rear intake valley seal. Heresay only, but I recall reading chevy guys forget that one from time to time.

BTW, All other galley plugs should have been tapped and plugged instead of using a press in plug.

I don't recall, what happened to the last motor?

One other thing, if it is the rear main, make sure there are no nicks on the crank use a viton seal (asssuming 1 piece here).

 

hahah, ya the chevy guys love to forget that big one under the intake! With that out though, you will have zero oil pressure

 

I inspected the galley plugs before install. Weird that the fronts were screw in type and rears were press in. or vise versa. I highley boubt the intake would leak as bad as the oil was. And visually I would have been able to see the intake leaking. Im going to pull the motor today and prime the heck out of it to see if I can locate the problem if it is not obvious. Hoping its a gally plug but i bet its the rear main. Which is gonna suck because everything will have to come apart.

 

its not the two piece rear main that you tap out and slide in the new half?

 

So I pulled the motor and there is no rear seal installed. bought a new one and I cant get the SOB to tap in. Any tips. I greased it up
