Possible Vct Damage - How To Test Vct Operation?

Yeah I was cautious about that as I've heard these are "interference" motors as they're known so I didn't move anything.

I'm just concerned I might have damaged the VCT cam gear/sprocket using a rattle gun. Must admit, I gave it a good 3 or so seconds before the bolt starting moving

well, the reason you are ment to secure the cam, is so you do not bend a valve.

doing up the nut with the camshaft unsecured won't bend a valve though, that would only happen if the cam turns. ( without the crank turning)

This is really funny, anyhow I'll share how I fixed my VCT.

So I tried disconnecting it and feeding direct current into it and to m surprise no change in idle, i.e. the damn thing is constantly advanced by 10 degrees.

So I thought, what if I drive it it constantly unplugged for a while, surely it might eventually pop back to no advance right? So off I went all weekend driving around with it unplugged, till the car became doughy as bat shit... (what a relief, no need to strip down the motor again!)

Plugged up the VCT, and bam.. car is back to normal!

I'm guessing either because I rattle gunned it's mum off and on I might have pushed it past it's rotational limits or so, OR there might have been air pockets in the sprocket when I reinstalled it.. either way, it's working now!

What do you mean"rattled gunned its mum off" you have said it a few times. Is that some kind of saying?

Well done fixing it!

hahaha, I think it's because I grew up with wogs..

It simply means I went hard out trying to get the bolt off with a impact wrench.
