Hey
I have a 350 1980 block with vortec heads extreme energy 274 cam. block was rebuilt 2 years ago and when cam was instaled 2 months ago crank bearings where also changed. engine seamed to run nice before cam, lifter, valve broke. it started making a very loud sound from the valve train and the bottem end seams to run good. About 10 min before the sound started i went under the hood and i opened the throttle at about 3500rpm and no noise ran very smooth. Now there is metal flake in my oil, very very small pritty hard to see but with a light in the dark you see there every where almost microscopic. I want to know could my bottem end still be good after all the metal pieces.

Thanks

 

Probably not, unless your'e a gambler that always wins. You have little pieces of metal all over you're engine now.....probably even in the bearings.

With any flat tappet cam (hydraulic or solid) you need to add either GM EOS, BG MOA, or a similar product with todays oils- be it dino or syn.

The oil companies removed the zddp from the oil products a few years back to appease tree huggers with less cat rot caused by burning oil, and the negative side affect is that todays oils will wipe cam lobes in no time. It happened to a buddy of mine 2x before he found out that was the cause of his engine eating cams.

 

Haven't ever seen one yet that survived 1000 miles after that happened. Usually not 100.

So I guess it depends on your definition of "good". Go down the track once, maybe; drive to and from work for a week, doubt it.
