I am in the process of repairing a blown head gasket on a 98 Pontiac Transport with 106,000 miles. I have removed the front head and feel the problem is in the #2 cylinder (1st cylinder on the passenger side) The piston head is clean with no carbon build-up. The spark plug from that cylinder is also clean. The other plugs are dark with carbon. I am tempted to just repair the front head and put it all back together. (The rear head will be difficult to remove since I have to remove the exhaust manifold from the rear and all this work is done by feel only- I've already rotated the engine.) Any recommendations on this?

The only thing to do is remove the rear head because engine overheats will warp the aluminum head and will not seal. It will start leaking if you put it back to use without removing and reparing the rear head. You may want to check the surface of the heads.

Maybe you can answer a question for me: Is the fuel rail one or two pieces?
