Oil come out from the deepstick housing. There isn't hole around block or in pan.

Try to pull out rest engine tomorrow. Going to rebuild it.

By th looks of the metal on on your cam where it's broke. It looks like it's been cracks for a while. It looks dark thru most of it then light. .if the piston are all moving when you turn it over by hand then the rods are still connected

Im not sure if anybody ever seen broken camshaft... Gear is in perfect condition...

Cylinder heads are okey but noy sure about crankshaft...

Any ideas?

that cam has been cracked for a while look at the color of the broken face .if it just happened it would not be dark. How on earth did you get that piece out. Dist.hole? It must have still been in place. Was ot still in place and just broken??

What!! Holy CRAP. Ok rear cam plug got pushed out then piece made it's way between flywheel and fell into bellhousing. Might have a broken block at rear. At very least flywhl damage. And crank flange too. Maybe your one lucky dude. Your going to find out when you pull ot out

Better pull it out first see of there is any major damage. Might be easier to order short blocks . I betting that piece did damage when it exited the block. If you sty5with flat tappet cam. Have someone run that engine before it's reinstalled. Sometimes the cams don't work harder properly and it destroys lifters, cam, also puts metal thru the engine. I always use roller cams

Exactly...

Camshaft was broked long time ago.. I agree with U. Maybe factory defect. Never now. Hopefully block is good. Cant find hole at thia time. Is it buy / sell department on this forum?


Lifters close to the broken side were loose or out from the housing.
