tapping sound

[Hothatch89]

I've just replaced the coil pack and spark plugs on my vtr, not long after, when I started the car up there was a strange knocking sound coming from the top of the engine, when I rev the car slightly it seems to get quicker as the revs build up and slows down as the revs drop....
Any ideas guys? Cheers. Ado.

Have you over- tightened the spark plugs?

[wullvfr]

Did you drop something underneath the coil pack

Or even in the cylinder?

Tappets may need adjusting,have you also got plenty of oil?

[VeiRoN]

Check engine oil i would say,just to be sure.

[silver.vtr]

Did you check the gap on the plugs when replacing them ?

tappets properly,

Yeah had this problem myself a few weeks ago, it's the battery mate, it makes that noise when it needs charging, hope it works for you mate.

In 7yrs on sax-p that has to be the daftest reply i've ever heard.:fcuk:

I had the same problem after removing rocker to replace gasket, tappet spacing needs adjusting

[DAMSK11]

Yeah I removed my clicking battery. Those things are a right bugger...

Honestly some of the replies here are retarded. A loose spark plug can make a tapping noise, so can Tappets but why would they be set wrong if they haven't been touched?

check engine oil like other have said, tappets could be the cause or even pre detonation?
