[FONT="][FONT="]As many of you know, I had issues with the 98 Volvo 3.0 I acquired. It had an exhaust leak and was seeing signs of a little water in the oil. Troubleshooting showed a blown head gasket and a cracked manifold. A leak down test showed air escaping out of the valves. A compression test showed horrible and inconsistent compression among the cylinders. A water jacket test showed a solid block without cracks. I took the head to a machine shop were they tested the head and found it wasn’t cracked, it was warped, and that many of the valves were not fully seating. They did a full head job and gave it back to me with an “it’s as good as new” send-off. I checked block’s top to make sure it was still flat, and it is. After putting the head back on I did a compression check; 140 psi across all cylinders. [/FONT][/FONT]

[FONT="][FONT="]I am now reassembling. During this time, while it is already tore apart, I want to do any other repairs or maintenance that is needed. I have already purchased new belts and plugs. I could, however, use advice on what else I should do. Here are a few things that come to mind. [/FONT][/FONT]

[FONT="][FONT="]By the way, I sincerely appreciate you all’s help this far. I could not have gotten to the point I am without you. [/FONT][/FONT]

- [FONT="]Before I tore the engine apart, the only way to crank the engine cold was with starter fluid. Also, the engine would die if let idle. Should I rebuild the carburetor, or put it back together and see if the condition is present? I’m not sure how likely the issue could have been caused by the problems with the head, head gasket, and manifold. [/FONT]
- [FONT="]Do I change the rotor, cap, and plug wires? I’ve come to the conclusion, based on my other thread, that I may as well. [/FONT]
- [FONT="]The flapper in the exhaust pipe is stuck open. Should I remove it? I know that it was removed by the manufacture in later application. [/FONT]
- [FONT="]Anything else?[/FONT]
