thanx for the info oxfordgt, do you think it could be caused by my manifold since i didn't replace the gasket. b/c around those two cylinders, i see a some coolent leaking from there.

 

Yes, that is what I meant. I didn't say it well I guess. Iwas also sayingthat the pressure that blew up your manifold is continuous down through your head ports to the head gaskets via the valve passages. If it was enough to blow up the manifold, it may have been enough to blow ahead gasket......thus the water. Thanks, oxfordgt.

 

yeah... thats what he's talking about (head gasket)

 

The head gasket is under the head inbetween the head and block. It blew due to to much pressure in the cylinder which is what caused the nitrous backfire which is what blew your intake.

 

It's a leakdown test, not leak downtest--this is a good basic explaination...

 

+1 if you have a compressor and you are able to do the leak downtestthen if its a blow headgasket you will hear air escaping from the other sparkplug hole.

 

what if my manifold is leaking too.
