383 lifter question

Get an oil filter opener----then look for metal in the element.

Good idea, thanks

I'd like someone to explain why they think there would be a lack of lubrication. Lifters are lubricated by splash, not oil pressure. My thoughts as a long time engine builder? A good method of checking a lifter is to place the bottom of the one being checked against the side of another. Hold the pair up to a light. You should be able to see light around the bottom outer edge of the lifter being checked. the bottom must be crowned. The circular pattern on the bottom of the lifter shows that it has been rotating like it should. If the lifter face looks good the cam will be fine. I'd like to see a picture of the bottom of the noisy lifter. Try pushing hard on it's piston with a pushrod. If it sinks you've most likely found your issue. A collapsing lifter.

The lifters pictured show abnormal wear.......which means the cam lobes have probably seen better days. New lifters will probably wear quickly due to some bad lobes. The cam needs to be inspected closely....& probably replaced. If the lifters are factory, better to have them re-faced rather than rely on questionable 'Made in America'. What is made in America, the circlip?
