Ok guys,
Just the other day when my car was cold I could here a tapping sound coming from the engine.
It then went away as my car got warm, but then the same thing the next day when my car was cold.
It has now got quiet loud, it doesn't do it when cruising or at idle just under load. I'm not quite sure if its there when revs get over say 4000rpm.
It is a constant Tap Tap Tap and goes with the engine revs.
Now one thing ive done is if i was to take off the plug to the spark plug on cly#1 the sound seems go away (revving it in neutral)
Im hoping it to be the exhaust gasket??? But could it be a big end bearing?
What test should i do to find out?
Any suggestions?
Thanks.
