Thread: help with the knock please

Nothing is too fast if it is bottom end related IMO...pull and check the plugs...if they are damaged then it is in the bottom end...if not...sounds like a bad lifter. Cheapest experiment I would try would be to buy some Lucas Oil Stabilizer and throw some in there and if it stops...THEN its valvetrain related.

Just curious, what could it be in the bottom end to tick that fast and consistent at an idle? Anything I've ever heard from the bottom end is knocking or clanking at a slower pace more on the rpm range of the crank from a bad rod or main bearing or wrist pin versus the faster valve train cycles.

You've never heard some of the things that have happened to my car then have you?

LMAO!

I had a rod bearing spin around...and it clattered VERY fast...strange...but it did...oh...and cam bearings that come out too sound pretty nice
