Just finished the install of my LC engineering exhaust manifold to finalize my turbo upgrade....
NO LEAKS... test drive and running some...
I give it a pretty good bit of boost about 8 psi and back off... sounds funny?
Then I see the white smoke pouring out the tail pipe... didn't make it 10 miles and blow a head gasket...
Was only about 1/4 mile from the house so I babied it home...
my question is can i just do the head gasket with new studs and be ok... it was running fantastic....😞

It's not unheard of for the local machine shop to loan you the precision straight edge you would need to check for warpage.

Fwiw, I think the big freeze we had awhile back killed my water pump. I'm gonna try to get in there this weekend, we are due nice weather, but no promises. Last time I was going to drive it before this time the distributor was wet and it didn't go ten feet before I backed it into its parking spot.

If you decide to upgrade to the head studs make sure your torque wrench is upto the task. I forget the number off hand exactly but I want to say it was 110ft/lb which made a dead spot on my HF ratcheting one..

If you have the equipment or can do the rental tool thing, do a leak down test..

Thank you Co...

I've researched and some say they've replaced the head gasket without removing the intake or exhaust manifolds... have any of you done that?

My turbo exhaust isn't easy to remove... but lce done it so many times now, i could do it with my eyes closed...
haven't ever done the intake side glad to hear it isn't too bad...
