although your break in procedure sounds good,what kind of oil did you use for the break in ??? :glasses7: anything with zinc ??
X2, it's sad but true. That missing metal has traveled somewhere and has probably done some damage. Pull it apart and clean and check everything, especially the oil pump.Pull the engine, disassemble, inspect crank, bearings, rings & oil pump. May need to replace bearings & polish the crank.
The way to prevent it for sure is to run a hydraulic roller cam.
Sorry this happened to you. Been there, done that. It sucks.
-low RPMs do not kill cams, set your idle where it belongs, improper break-in kills cams.Yeah but roller lifters can still break. With mild cams its not a problem but then same with lifters going flat. The bar the roller rides on can break or wear out.
Zinc helps the bearings and pistons also. These new cars get 200,000 miles on their engines due to reduce rpm's and they are de-tune, not making close to max power.
-sorry but I disagree, yes they get 200K but it is due to superior engineering and they certaintly are not detuned and they run at higher max RPMs then early stock engines ever thought of running at.
improper beak in caused the cam to go bad. Did the engine fire right up or did you crank and crank the engine to start it. Did you change the oil after the 30 min semi-break in ?
I didn't relax till 300--500 miles was on the engine. I kept the idle at 1,100 rpm till then and even now have it set at 900 rpm's. Low rpm's kill cams
Hey guys, Im just curious...everyone is mentioning different oils and such, but 72DSV8 mentioned at the beginning that he did not prime the engine, could that not have been a contributing factor?? Just curious.....
