China Retro Hyd Roller Lifters!!

A good friend of mine is building a BBC for his 34 Ford Coupe. Wanting a trouble free (?) setup he decided to go with a hydraulic roller cam.

Ordered some hydraulic rollers from an internet vendor. The first set would not fit all the way down in the lifter bores. They measured .0025" larger from the oil relief to the top of the lifter?? Sent em back!.

Second set arrives. The guides that keep the lifters from rotating on a BBC are not installed correctly. Can't get the lifters in the bores!! Send em back!

Third set, all fit. Oil pressure pumps up all but 4 lifters. These are stuck all the way down. Dis-assemble lifters and the plungers are STUCK.. A lot of religion later the plungers are removed and in the bores is TRASH! Metal shaving and casting slag looking trash. Cleaned em out and re assembled. Now they pump up. Haven't fired the motor yet.

SO what if all that trash gets into the oil stream down wind from the filter. You know what happens to bearings etc. WATCH OUT!!!

Let me guess, bought from a Chinese manufacturer? Possibly even a Chinese seller. You can post the sellers/manufacturers info in the feedback forum to help others from making the same mistake.

Ive seen a set for a Pontiac that the lifter body length varied by 1/8" from shortest to longest. Thats .125 thousands. Two of the lifters were so poorly machined that the roller wheel couldnt touch camshaft becaause the "ears" were too long. Just imagine the damage these would have caused if the defects werent found before fire up.

Everyone needs to be carefull about buying "cheap" parts, there's a reason that they cost less, and it ain't because the seller is a swell guy.
