it was changed around 40K miles ago...

 

I finally got the camshafts out... here are pics one of the cylinder head and one of the damaged camshaft... is there anything that can be done to re-use the head and camshaft or do the need to be replaced??

 

It looks pretty chewed up on that last bearing there. Do you feel anything when you run your finger inside the cam bearing? Any knicks and whatnot. Im gonna say you COULD still use the head, but if it were a dealer repair, that head would have to go.

Edit: correction, if it were a dealer repair, that ENGINE would have to go per the TSB. I think you can get a used head from www.shokan.com for pretty cheap though which should save you some moolah if you decide on replacing it.

 

can the head and camshaft be machined so that a bearing can be used??

Edit: sorry, to answer your question the cam bearing on the head side is chewed up pretty badly as is the cam... there is a big difference from the damaged intake cam and the undamaged exhaust cam...

 

I'd say no..there's prolly not a ready made solution. So unless you really do you homework and find a compatible bearing, get every thing machined correctly, get the cam journal turned, etc, etc.. You would still have to get that block's oil passages cleaned out which means at least dropping the oil pan and pump, pulling the other head, tensioners, check valves, and anything else oil related or in the way. In the end it would prolly be cheaper, quicker, and easier to swap the head and cam and clean, if not swap the motor itself.

 

i found a head along with camshafts for $600 from a dismantler. I'm going to have them disassemble the head so that I can inspect if before I buy it. So before putting the head back on I should drop the oil pan the oil pump should be removed then where do I go from there?? What am I looking for when I drop the pan and pump??

 

Sludge.... Get some cleaner and clean out the pickup screen, pump, and any passages you can get too. You can use those long oil galley brushes (rifle brushes) so you can chase the oil passages and clear them out. Just dont push crap from a big main passage to a smaller one or you'll plug it up more.

You could prolly get away with just cleaning the heads (both), chasing the oil passages in the head, cleaning the pan, pump, pickup screen, cooler adapter, etc, then run it with Seafoam for alittle bit to clean the blocks passages. This would best be done after its running correctly again using a light oil like 0w-20. Dont run the engine under heavy load while the light oil and Seafoam are in.

Here's some info from a guy who had alot more sludge problems:

Good luck.
