340 issue after camshaft change

I’m convinced this camshaft is bad from the manufacturer. It is coming out.
By bad, what specifically do you mean? Ideally before settling on the cam being at fault, wouldn’t it be worth it to partially disassemble down to where you can check and verify everything you have done is correct, and if that all checks out then move on to ultimately diagnosing where the problem lies with the cam? Yanking and slinging it may give some gratification (I like smashing defective things but that’s just me:eek:) but how can you be sure it in fact is the issue without first verifying everything? Find the actual fault/issue first regardless, then perhaps “sling” :thumbsup:
