Stuck tappet in block

[Loren Warman]

I have been working on what I thought was a stuck exhaust valve in #4 cylinder of my 1952 8n.
After doing the MMO,PB BLASTER and brake cleaner
with no luck I pulled the head and valve cover.

The valve is loose and can be rotated freely so it looks like a stuck tappet.

Does anyone have an idea as to how I can get the lifter to move. (it has had plenty of pb blaster)

Thanks to all Loren

Loren,If only one valve tappet is stuck on #4 cylinder,roll the engine over till the one thats not stuck is open all the way.Then gently tap the one thats stuck open down with a small hammer and say about a 1/2" bolt hex down and square on the valve head.Tap it down and keep spraying it often.When it taps down roll the engine over again till that other valve is open before taping it down again.Keep repeating till it moves open and closed while cranking it over.

Den M :
Your suggestion worked like a charm. As soon as I get her put back together I will be back in business.
Thanks a million

Try some Kroil next time.Ive got the box off my pick up. Its upside down to get 2 new cross channels put in.A fender brace was rotted, time for a new one. One end was bolted to the rear cross piece.Captive nut so if I break the bolt I have trouble.Had put some MMO on it the day before.Started it with a half in drive 6 point socket and a breaker bar.Got 2 turns and it bound up.Put some Kroil on it and work on some thing else for a while.Try again, turn it back in a bit.Backs right out with little pressure on the breaker bar.
