1928 Regular update

well, after getting sidetracked with the F-14 and getting her running, I am back to the regular. clutch is working find now, and the coupler is rebuilt (ouch on the cost of the plate).

So, she is nice and free on the engine, but no compression. Did a number of tricks, and still nothing. Took the head off, and the old girl needs a valve job in the worst kind of way. Seats are going to be fine, just need to dress them up. Ground new faces on the valves and was able to salvage 6 of the 8 valves. 2 are junk. 1 broken valve guide. So, I ordered 2 valves, 1 guide, and keeps, retainers, etc, since these are the old style valve keeps.

I have a question though, as I haven't seen this on a "loose" engine. The valve that had the broken guide had a bent stem on it. Probably what broke the guide. I see no indications of anything nasty in the combustion chamber. In fact, the sleeves are in really good condition, which makes me think this may have had new pistons and sleeves at some point.

How the heck does a valve stem bend on a low compression, loose engine? Was thinking of a couple of scenarios, but couldn't come up with a possible answer on it......unless the valve was bent (new) and installed that way.

Tom, Not knowing the history or what the po did make us like detectives. you try to figure out what was done or not. I picked up a Regular for parts it had a bolted on patch on the block 4x10
so I was not going to fix it. I pulled the head and opened the block I wash I had looked sooner.
Very little wear and supper clean. If that patch held this engine would have been like new.

Oldiron29, I agree with you. The cam, lifters, crank, rods, etc on this old girl are in excellent shape. Sleeves and pistons are really nice, no ridge, no pits, flat out clean. This all makes me think that this old girl had a new set of sleeves and pistons installed at one time. PO family told me that old tractor was bought new and worked all the way up into the 70's. Can't believe that much running and no wear in the sleeves (ie. ridge).

The head gasket was also stamped with the old style IHC logo. Not a crisis, just curiosity on this. I have never seen a snapped off guide before (worn out ones yes, broken no.) One would think the push rods would bend before the valve stem.......makes one wonder.

Tom,I work in the waste water bussiness,we were inspecting a 8 in sewer line which is one of our main lines,and is inspected regularly,and found a 4 ft level that had to find its way around several bends in the pipe.I never understood how it happened but it did.

Interesting question...

Water in the cylinder CAN bend a valve, and could theoretically leave no other traces behind, provided there wasn't much of it.

Kind of have to have a lot of stars aligned just right in the universe for that to happen, but it can happen.

I've heard for some reason it would bend intake valves - not exhaust valves since they open only when there's a large amount of volume in the cylinder I guess... never really thought through all the physics involved there.

But that's the best I can come up with.

Was it an intake valve, or an exhaust valve?
