I'm a little late on this thread but were the head bolts still tight when you took them out? I have a Techumseh HH120 [I know - wrong brand] that used to have "automatic compression release head bolts"!!! Once it quit running and cooled to the touch, I could take the head bolts out with my fingers.


They were all tight.

This is easy to diagnose if you can do a leak down or just make an adapter and hook it straight up to the compressed air and you will hear and feel it leaking out

It looks like to me, that the exhaust valve has some build up on it, also the head gasket looks to me like its been leaking.

I'm going to clean up the valve some and put it the head back on and torque it, and see if that makes a difference. I ordered some gaskets and a new exhaust valve today, they should be in on wednesday.

Mike, I got antsy and didn't take time to do a compression or let down test before I popped the head off.

If you rotate the engine till the exhaust valve is closed, make sure there is some lifter clearance.
put some thin oil penetrating oil on the valve all around the seat,
blow some compressed air into the exhaust port,
if you see bubbles around the seat, the outside of the valve, then it's not sealing right.

Dosen't look like the valve has a good seat, Was the seat ground or just lapped? Also were the threads in the block chased? Was the head planed evenly? The head gasket looks good to me, Clean it up a bit and coat it with silver spray paint.

Not ground, but lapped fast & a perfect finish. Threads were chased. I checked the head with a straight-edge & looked good. Head gasket has been re-used already....with the paint trick.

Do you think possibly the compression release on the cam is not working properly and continuing to hold open the exghaust valve?

I tried to get warranty work done when his muffler had a "faulty weld", he started to agree and then brought up a lack of documentation (sounds like a crooked dealer to me :poke:). Also I dont think i could afford to have he him come up and pick up the tractor and then return it after fixing it.

I didn't know about this trick. head gasket, valve and a few other gaskets are supposed to be in Wednesday, but this winter storm may push that back.

I truly hate that you are having problems with the Ford....seriously. I wish you were closer, as I would do free labor without a doubt.....and without documentation! :thumbs:

Still hard to tell by the pics, but the exhaust valve appears not to be burned. It does look like there may be some white carbon on the sealing face of the valve??? Doesn't take much of a speck of carbon stuck to the valve to dump your compression. The head gasket may be the culprit. Do be sure the valve still has proper clearance. The aftermarket valves may seat softer, so clearance could have been taken up???


i do believe Daniel has your problem figured out ! its defiantly your valves with a touch of gasket ! just from the cranking speed sounds like compression problem & pics with the head off almost verify that ! i think your on the downhill slope now!!! :wave:
