Thanks,

I think I replaced some of the studs a number of years back. I can check to see if any bottom out on the top side of the head.

There could be a crack in the block also.

Water distribution tube?

Greetings All,

Thanks for all the ideas and info. I did get the head gasket replaced, new hardened washers, cleaned the threads on the studs and nuts with a tap and dye so everything would torque right. I did put a straight edge on the top of the block and did not see any warpage to speak of.

I did a compression test and found that I still have no compression in cylinder #2. Is it possible that the valves are so far out of adjustment that a cylinder would have no compression?

This one is truly puzzling.

Thanks
Gene

It's nearly impossible that NO compression (meaning zero) in #2 could be the result of valve misadjustment, or even a crack in the block or head or a leaking gasket. Do you really mean NONE? If none of the valve heads (exhaust especially) looked burned, then I'd beging to think in terms of a valve with a bent head or stem. This could be the result of running an engine, even for one revolution, with insufficient clearance for the valves to open before contacting the head. Another consequence of this can be that you'll wear a cam lobe and that can happen VERY fast. Even extremely worn rings would still give some compression.

Whenever a cylinder head is off and the prior history of engine condition is unknown, it's a good time to pull a few valves, especially exhaust, and check the condition of the seats and valve faces. Any single one being suspect would be reason to do a valve grind. I didn't read back thru all this thread but did you happen to check these things?

I'd suggest finding and correcting the source of the no compression first, then verify that there is enough clearance for the valves to open w/o contacting the head, and then tackle the overheating, somewhere in this site is a long list of candidate things to check - I know someone will find that source and reference it for you.

Did you check the head itself for flatness?

I wonder if you may have a valve stuck open. Easy way to check would be to remove the valve cover and hank crank the motor and see if there is smooth action the valves on the affected cylinder. Also you have the head off, you can also hand crank the engine to and check the action from the top side.

I remember someone posting about have a "dead" cylinder only to discover that the piston was wedged in the bore, but the connecting rod was totally missing. So everything looked ok until he cranked and realized one piston was not moving.

Never know what strange things could have been done by previous folks.

Hi,

I replaced the valves a year or so ago and yesterday went in and adjusted them with the car running to the required specs. The #2 valves all seemed to be moving up and down with the rest.

Still no compression. Is it possible that the piston rings may have failed and all the compression is blowing by them?

I've run out of ideas.

Thanks
