Metal fillings in oil and cam will not come out
The engine was hot tanked by the engine rebuilder. All the machine work was done by the same shop. The block was line bored because of a past thrust bearing failure. Block was planed and bored. Cam bearings installed. All oil passages cleaned and plugged, soft plugs installed. To help with time I had them assemble the long block except for the intake. Yes I was knee deep in it after work until it got dark. Bad news is I can not get the cam out. It moved ~2 inches forward and that is it. Turn all you want, pull, push. Will not come out does not seem to want to go back in. Face of the #7 and #8 cylinder tappet look rough/pitted. Other tappets look great. I believe the bearing has spun in the block and is welded to the cam. I will have to borrow my friends scope to get a closer look. I am pretty sure the engine builder is going to hang me out to dry. Any good ideas how to get cam out? My other thread was closed. Bruce

Re: Metal fillings in oil and cam will not come out
I was so proud to keep this truck numbers matching and now I believe the block it was born with may have a spun cam bearing. I am starting to have a bad feeling/nightmare like. I am frustrated.

Re: Metal fillings in oil and cam will not come out
If you really want to keep it numbers matching the block should be able to be machined and be fixed. Note I said "should" although if it is junk then there is no hope. If I where you I would try to find a block that was made the same year as the truck and I don't think anybody will be able to tell. Except for me of course.

Re: Metal fillings in oil and cam will not come out
Get a bolt that threads into the cam nose and hook a slide hammer to it. If the engine is in the truck you'll prob have to take off the grille and remove the rad. I'd definitely try to see what was causing the hangup first(although iirc ya can't see the cam very well from the lifter valley. I'm used to Pontiacs where it's wide open.).

Re: Metal fillings in oil and cam will not come out
Yep fuel pump rod. Cam is rounded off. Time for the clean up because of a bad cam. I will be able to save the block. Thank you for your help. Bruce
