Well look what I found today

What should compression be on a 3.0 merc on each cylinder? I had no compression on my center 2 cylinders and this is what I found I dont see any burns onto the block or head. Im just gonna have the head surfaced and put it back together. Is there anything else i need to look at while its torn down??

man now thats a blown head gasket .. while you have the head off i would have it checked for warpage and surfaced if nescesary i see alot of warped heads that need surfacing at the machine shop .... usually not to expensive to do when compared to gettin it back together and havin it happen again ... good luck

starting fluid (ether) will do that too.

On the exhaust manifold side do i need a new gasket or is high temp red rtv acceptable? What sealant should I use on the head bolts?

New gaskets. For the bolts I use head gasket cement.

Perfect seal for the bolts, NAPA (Permatex) aviation sealant a good substitute. Depending on the age of the engine you might consider hardened exhaust seats, your machinist should know if you need them.
