Knocking Engine - Argghh!!
Just took delivery of my GTV bought via ebay (unseen!!)
anyway she has arrived with one hell of a knocking engine, sounds very top end. Almost like a sticking valve. However compression is spot on on all cylinders.
Checked coil packs they all ok, thought it could be injector knock, so removed injectors connectors one at a time and found that when i removed 1 injector connector on the suspected cylinder the noise dulls away to nearly nothing. at idle but then with a rev it returns intermittantly.
I have removed all the coil packs inserted a long screwdriver and given the piston crowns a tap, they sound ok however there is a slight thump from the suspected cylinder. Would this indicate a little /big end fault.
The strange thing is it sometimes clears especially when you wiggle the coil pack wiring,
I though i would see if anyone else has had a similar problem before i take her to bits.
the other thing to note is she runs very very hot. as in block temperature, could this all be linked to a fuel issue? or is this wishful thinking.
