Cheap Chinese Hydraulic Lifters

[1-ton]

I had a small block engine, with only 60,000 miles on it, loose a lifter with no warning. The engine was a medium duty 4-bolt main small block from a large mass producer of rebuilt engines. I have read some articles and posts that China is manufacturing most hydraulic lifters these days because the demand is low due to the emergence of roller lifters.

I would assume that most of the major camshaft manufactures, such as Edelbrock and CompCams are currently selling the cheap Chinese lifters with their camshaft kits. Now that I need to replace my camshaft and lifters, on this engine, what would be the best way to buy a low performance RV camshaft with a reliable set of hydraulic lifters?

This engine is connected to an OBD-1 ECM, with throttle body injection.

Comp Cams, Howards, Lunati, Delphi, Eaton and Engine Pro are made in USA

I will have to look at Comp Cams if their lifters are made in the US.

Great info, I might add that I have been using a zinc additive sold by Hughes Engines, www.hughesengines.com , in my flat tappet engines and haven't had any problems even with high lift cams and strong valve spring pressure.

I've used the Comp Cams additive for a few years now....my small block showed no more than .002 wear from new....maybe only 2500 miles on it, but there was a LOT of redline runs in there too.

Funnernhell!

Comp Cams PN# 252AH-12 looks like a good cam. Summit Racing.com has them for $127 and the lifters for $87.
