Re: Head gasket replacement?
We could use some more information, such as: What engine? What year? How do you know it's the head gasket? Do you have experience replacing head gaskets? Do you have a torque wrench and know how to use it? Do you have a manual for your engine? If not, you'll need to get one to follow the sequence. In general, after you pull the distributor, intake manifold, exhaust manifold (maybe), you need to loosen all the rocker arms and remove the push rods, keeping them in order. You then need to remove the head, check it for warp and cracks, check the block for damage, and clean everything. Then, assuming all is well, you need to set #1 piston on TDC, replace the head gasket, torque the head properly, in stages and in sequence, reinstall the pushrods, set the distributor to line up with #1 wire on the cap, set the oil pump gear to match, drop in the distributor and tighten tentatively. Then you need adust the valves as outlined in the manual. Finally, you need to reinstall everything you removed. You then need to start the engine and set the timing. That's a quick summary of the process. I strongly recommend that you get the manual before you start anything so you can check the specific details related to your engine. Good luck and safe boating, Hy
