I'm putting together a used motor and am darn close to out of money. The cam 'looks' OK, but the lifters are slightly dished. Do I:
1. Put new lifters in it? 2. Regrind the old lifters (I have and extra set that are shot too... so I could pick and choose the best for the regrind) 3. Run 'em and try to forget about it (gonna be really, really hard to do) Opinions? -Aaron |

I have had the lifter issues solved for over a year now... We have had two failures out of 300 cams that have been sold.
As far as reusing a cam and lifters, either leave them 100% as is and reuse them, or start from scratch with new compatible components. Anything else is a game of Russian Roulette that you more than likely won't end up winning. Oil selection will help, but its not magical. Incompatible materials and profiles will fail even if you ran liquid gold as engine oil. Thats just the facts. My solution is not cheap, but the effects if you do have a failure can easily cost you an entire negine. Is your engine worth 300 bucks? The effects of a cam failure are extreme, metal particles circulating through the oil wear anything and everything immediately. Anyone who had had a failure will tell you the hassles were worth 10 times the cost of my cam and lifters, the damage can be that much or MORE out of the pocket. |
