I have a 1976 Merc 165 IL6.
Did a compression test after running the motor and letting it sit for about an hour.
1. 125
2. 110
3. 140
4. 140
5. 140
6. 140
I am getting a fine mist of water out of #2 when the engine is cranked w/o plugs. No water at all in oil. Engine runs perfect after 1500-1600 rpm.
The engine has a bit of a miss below that. Starts when you hit the key and has plenty of power.
Headgasket or crack in block? Where do you start in trouble shooting?
Full tune up has been done including setting dwell and timing, both are spot on factory set. This is my first I/O and I'm learning and i have the factory manual but the troubleshooting section doesn't get deep into this.
