Rebuilt Engine, Head Leaking

I have a rebuilt engine, F134, that I got back from them machine shop. After the first start up or two I noticed coolant weeping from the head. I took the rocker cover off and re-torqued the head to 70ftlbs. After running again for a few minutes the weeping comes back. Any suggestions before I pulled his head off again?

Did you assemble it or the shop?

 

The shop

 

just noticed this evening.

 

I should mention that it is doing this in several spots around the head.. not just that one

 

Discuss it with the shop before you do anything more than you have already done. You don't want to be accused of causing the issue or, making it worse.
A reputable shop should stand behind their work.

 

We’ll a little update. They had me take the head off and bring it back to them. They milled it (they couldn’t remember if they did it the first time) and cleaned it up. Brought it home and put a new head gasket on. Made sure to torque down to 70#. Started right up. I let it heat up, then removed everything to retourque while it was till hot.

and it’s still leaking. I’m at a loss and very defeated.

what should I do at this point? Try a bottle solution? Torque down more?

it’s a very slow drip, but it’s there.

Ugh.

 

Did they deck the block????

They "can't remember?" Do they remember if they billed you for it???

The shop built the engine, it leaks, but they want you to do all the labor and travel to correct this? I call BS.


Once I had a shop mess up a job. They said they'd 'fix' the damage they did. I told them, no, I would get it repaired some place I trusted, and send them the bill, and that's what I did.

 

Not sure if this shows if it was decked or not.. This was what the block looked like before I put the head gasket on after they milled the head.

 

Is the engine number still readable, just in front of the #1 hole? Decking will remove that, unless it was re-stamped.

 

The deck looks very clean, but can't tell from your photo if the deck was surfaced. Looking at the photo, is the leak at the front of the block? That shows some discoloration.
I would not use any stop-leak type product. What brand head gasket have you been using?
If a shop rebuilt/assembled the engine, it should be on them to make it right. Show them your photos and see what they say.

Between the black crud in the combustion chamber area and the grade stamps near each cylinder on the distributor side, I'm saying it has not been decked. Maybe get a quality straight edge on the deck and see if it's flat or not. But yeah, it probably should be the machine shop's baby.

 

It was a felpro gasket. Both times.

 

Well, they are having me bring it to them, running in the jeep... have to flat tow it most the way before I drive it the rest to let it heat up.. it sounds like they want to make it right. I just have a feeling that means I have to take this damn engine out again.. ha

 

My comment isn't worth much be here it is.
I've always been in the group that much prefers to run just water in a brand new engine.
Break that engine in and run it with just water.
Some shops will even tell you to do this as part of the break in process.
Are you driving the Jeep or just letting it sit, idle, and come up to temp ?

 

MY vote is the Studs (should not use bolts unless trying to be military correct) were not properly sealed.

 

Yeah I think I am going to replace the bolts with studs and goop the threads better and replace the gasket one more time before I rip the engine out..

Does anyone offer a stud kit for the f134?
