Help! Coolant and oil leak!

[DodgeBoy777]

Just rebuilt my daytona engine and fired it up a couple days ago. It ran fine but I had to shut it down after a short run because of a big oil leak. I looked around and found the oil tube between the turbo and engine was leaking but I was not convinced that was the only leak. I got under the car and discovered that coolant was dripping from the exhaust manifold. The head and head gasket are new so I am assuming that is not the problem. I have heard that the manifold bolt holes can leak coolant but I was not sure if that applied to this particular cylinder head.
So anyone have any ideas on the coolant leak?
Thanks in advance.

sounds like a leak at the ex manifold studs

i agree, sounds like the exhaust studs into the head. also could be leaking oil from intake bolts too(a fe of them protrude into the oil.

[DodgeBoy777]

So did i just not get them tight enough or do i need to use some sort of sealer to make the studs not leak?

[onerippinturbo2]

i use high temp thread sealant with teflon(liquid teflon tape) on all the studs and bolts for the intake and exhaust into the head, prevents anything from rearing it's ugly head(coolant and oil leaks)

Alright Ill try that. Thanks for the help!

no problem, keep us posted on the progress!!

Any tips on how to get the intake manifold off while in the car or is it even possible. I really dont want to remove the engine unless thats the only way to do it.

[Dr. Johny Dodge]

the exhaust manifold needs to come off first before you can even get at the intake bolts above where the turbo mounts on the exhaust manifold

hard to do in the car - very hard

removeing the front motor mount and the boble bracket on the diff will help as you can then tilt the top of the motor forward

I'd try to identify which bolts actually leak and only worry about them - at least at first

but really it would actually be easier to pull the motor & trans together then fight to try to work back behind the head

Well I think I'm going to pull the engine. I was able to get most of the bolts off both manifolds but there is still about 3 or 4 left. I think it would be much easier to remove and install the the manifolds plus I can check other places for oil leaks while the engine is out.

Pulled the engine yesterday. Some of the manifold bolts had coolant or oil on them so ill have to seal them up. I also noticed some oil on the flywheel but the rear main seal appeared to be dry. I think that oil came from the oil tube connecting the engine and the turbo. I plan on fixing those things and the dropping it back in tonight or tomorrow and starting it in the next couple days.

Started the car today and I think all the leaks are taken care of, however a new problem has come up. The engine would run for about a minute and then it died. Theres was some white/grey smoke coming out the tailpipe. Tried it again and it lasted a little longer but died again. It also had some smoke with it. Both times i started it the rpm were about 1200 for a few seconds and then dropped to about 800. I also checked the fault codes and got 12, 13, and 37. 12 was about the battery disconnected, 37 was something about the torque converter but 13 said the MAP sensor was not getting a proper reading. So could a problem with the MAP sensor be causing these problems or should I be looking elsewhere?
