Replacing head gasket

[robbyr1]

I am replacing a blown head gasket on my Glastron SX175, 3.0 Volvo Penta. I blew the head gasket when my motor overheated. As a winter project, myself & a couple buddies are breaking the motor down. I'm going to have a marine mechanic put it back together for me (ALOT cheaper this way).

We have taken everything apart (bad impeller, bad exhaust bellow & bad head gasket between 2 & 3 cylinders). I am hoping that replacing the head gasket and putting it all back together is gonna work. What are the chances that this is it? I am gonna check for warping & all that before the gasket goes in. Do I need to worry about pistons, valves etc. being bad after 1 overheat?
What do you think?

You need to worry about a cracked head.

No cracks in the head

Take your time and learn along the way. Very rewarding and it will save you big $$. Plenty of experts here to answer questions. While you have the head off, you might check the valves. There probably is a better way, but I made a valve seal checker by using the head mounting hole to bolt the head to piece of rubber on a 2x6 and using a leakdown tester to check if the valves leaked.

A machine shop charge should be around $20-$40 to clean and check the head for you. Money well spent if they find a problem.

Money well spent if they don't find a problem too

Cover your butt! Have a machine shop pressure test the head and manifold.
