Unhappy Camshaft removal - 289

All-

My cam seems stuck. Engine was turning fine before I started the teardown. I've removed the crankshaft, pistons, etc, (it's down to the block), and all of the lifters. Now it barely turns using a breaker bar, and I can't "gently slip the cam out of the block" like it says in my "How to Rebuild the Small-Block Ford".....

Any suggestions? Am I missing something?

Thanks!!

Could be that your bearings have seized? Were any of the lifters torn up? If the cam's toast, then your bearings are toast too, so unless you truly booger up things getting it out, it should be fine. New set of cam bearings, new cam (and go roller this time so you don't have to monkey around with flat-tappet breakin, and ZDP additives, etc.) and BAM!

Hope you manage to get it outta there. =)


I smile a lot. It makes people wonder what I'm up to...

If you can turn the block upside down, try spraying penetrating oil on the cam on both sides of the bearings (those that you can see). Or, if the block is still in the car, try to spray as much penetrating oil on the bearings as possible. Hopefully, this will lube the bearings enough to twist the cam out of the bearings. Otherwise, you may have to use a bearing puller on the end of cam or possibly pry it forward with a pry bar.

Thanks - could be seized (but would the engine have rotated OK while fully assembled if that was the case?). The lifters looked fine and came out with no problem. Definitely going roller cam though!

Thanks - the block is still in the car for now, but it's all alone- tranny is out, as is everything under the hood (except steering and suspension...). I'll try hitting it with oil tonight and try again tomorrow... If that doesn't work, I'll go ahead and rent a hoist this weekend and put it on a stand so i can get after it from the bottom.... Appreciate it!

I would try a dowel of wood and hammer to tap the cam back into the block. Maybe you have a wear lip on the bearings and it is gotten wedged somehow. I might be tempted to put a bolt in the can and finagle a pry bar to lightly pull out on the cam. Push in, pull out, maybe something will give. I am not suggesting any real force, just some light exploratory persuasions.

Ride On,

Thanks - I've got the engine out now, flipped upside down, and am soaking the bearings with penetrating oil. Going to let it sit overnight and see if it shakes loose - if not, I'll try the wood dowel!

At the very worst, you could probably put the block on top of a couple blocks of wood front end down, then pound the cam out from the back, block plug and all. It'll have to come out anyways to replace the cam bearings, which sounds like it's necessary.

a 50/50 mix of acetone/AFT or marvel mystery oil is excellent penetrant that does do some miracles!

Thanks Paul, that did the trick. One of the bearings came out in slivers, so I'm guessing that was the issue!
