Title: tapping knocking noise
Post by: zakk2wylde on December 06, 2014, 19:59:19 PM
Any help just started getting a tapping and knocking noise more when you accelerate and it seems like it's misfiring engine is 16v redtop could it be a spark plug problem

Ive got the same problem , some say its a hydraulic lifter, which is a tappet, and other reckon its a big end bearing knock.

if it increases when you rev, the information i received is that its a big end bearing knock or the small end bushes of the piston.

hopefully crank wont need to be cut?

HOPE ITS NOT THOUGH.

I’d check the spark plugs - look carefully for ones which stand out as looking different - could be as simple as a bad plug, lead or injector
