Thread: Certainly not what I expected.

i would grind the valves and the seats. if you do not have any valve equipment so lapping will do. if you hit the seats with a wire wheel . if the intake is that black valves were not seating or push rod pop out of cup held the valve off seat ? your going to hear some compression past the rings in the pan. rings would have to be stuck in the ring s lands closed up to pass all compression walls could be glazed up abit from to rich but that s not going to get you O. its in your upper end. compression out the ex would be a ex valve .compression pass the intake valve would come out intake . can be check with putting air in that hole .i know you know this but it may help some one

Yeah Ken, the dipstick was continually being pushed out of the tube about an inch or so. I would push it down in and then later on find it up again after running the engine. In the beginning I thought it was vibrating out but then I realized it was being blown out by compression.

Pat, you are right, I think I'll pull the other head since I am this far along and remove all the valves and clean up the chambers and valve faces. I think I have a combination of things going on. I think perhaps all the rings were leaking a little due to the cylinders being washed, and that might have been the compression in the pan. Then I think the worst part of the compression loss was through the valves in that cylinder. I was just assuming there was some major break in the piston because I thought all the compression was going down the rings. But I bet that the valves were my real culprits.

I don't want to get into having a valve job done on these heads right now as I want to keep concentrating on the Ford engine I'm building. I just want to get the T back drivable and try to get a few more miles out of it before I do a proper rebuild or maybe build a different engine altogether for it. I think if I clean up the valves and run a shock treatment of Ring Free through it for a few tanks of gas, plus lean down my fuel mixture, I might be able to accomplish that.
