There is a good chance that the engine has worn cam bearing and that makes it hard for the oil to reach the rocker arms.
How many miles are on this engine?

i have a 1968 slant six and very low compression. the rocker assembly was dry too so i pulled the head. the oil holes in the block to the head were dry also. i pulled a piston the rings were dry. it was a miracle this motor ran at all! i blew air through one of the oil holes in the block and i heard it escaping at the rear of the block. is the rear oil seal blown and thus not pressurizing the left side of the motor which supplies the head? i never saw this before. anybody got a slant six for sale? i'm in oklahoma city. jim |

wow ! thanks you're the first person who has said anything. and the graphic is really helpful too. the engine is old for sure. bored well over stock. i guess next thing is to pull the thing and make sure i can bench pressurize the situation. apply some kind of external oil pressure and see if it can reach the oil holes. i guess i could just put the pump back on and crank it also. heave ho! jim |

Better yet, go under the engine and pull-out the pressure sending unit or oil pump's releif valve, install a hose connection fitting into the tapped hole and apply oil pressure thru that connection. DD
