Got a slight knock at idle but not at revs?
Any ideas?
Tmi seat covers where to get from?
Petronix dizzy will it fit and worth it?
Thanks all

is it constant knock or erratic?

Constant but goes away when you start to rev it

Looking forward to hearing what the knock is.hope its not serious.
Had a beetle with what sounded like poorly adjusted valves or pinging on acceleration,never realy confirmed what it was,but
when we eventually pulled down the engine,couldn't believe the play on 2 of the big ends.........

in a type 3 check the cooling fan bolt, the one with the belt from the generator. usually has a black plastic dome covering the bolt

yep as per above have you done the tappets what grade oil u using has it been change recently and filter washed

pretty common problem on type 3 is the fan hub coming loose from the fan. its setup with rubber mounts and is like a harmonic balancer.

Have a look at that first as its common for making a knocking sound that comes and goes. generally the knock is a bit erratic at idle but does vary car to car when it happens.
