Well I finally got around to digging in to my problem, looks like the new cam wiped on a few lifters, the metal filings from the lifters mixed with the fresh cam break in lube and clogged the oil pickup. The good news is that everything else in the engine is fine. All the bearings just started to show copper, crank is still nice and polished. Cam bearings and rod bearings all good. I think the timing set must be mismatched for a magnum series cam. The 268 cam had a lip around the cam bolt hole, the new 280 didn't, so I'm sure that when i tightened the cam bolt, it sucked it out of alignment and started wearing on the center of the lifters. Time to call CompCams and make them give me the reason for the differences in cam cores.

 

Well Glad to hear you got her figured out, keep us posted on how it all works out with the new cam....

Russ, have you ever seen 2 just slightly different cam sizes but with a totally different cam core? Seems to me that they would just build the cam off the same cores.

 

Nope cant say that I have...Sounds to me like something that got by Quality Control?

Now I need opinions, do you guys think that I should get the block tanked and cleaned since the oil has lifter filings in it? Or can I just give it a quick self clean and throw her back together, my machine shop won't have an opportunity to clean it for about 3 weeks (they have too much work).

 

As Much as I hate too say it? (if it were me) Becuase the cam chewed the lifters and they have an Industrial chrome on them..which it Hell on bearings...I would pull it all back apart and give it a good cleaning..and put all new bearings back in it!!

And Clean all you parts again before assy. lube and pre-Oil prior to the build again!! JMHO...and look at all parts a passages that would come in contact with the contaminated Oil..
