Well, i changed the head over to the A pack one, took a while, first go, had my mate who works at vauxhall to help me like.
all went back together ok, found out there is a bit too much play on my pistons and my rollers are on their way out. bugger.
On the plus side, i can go for a 2.1 rebore when i get my trick bits
On the down side, it idles like a bitch, really rough, when i am driving its fine, jus rough idle.
Any ideas what could be causing this? anything i can check? put everything back how it was, and double checked it all.
I aint opened her up, but even at low revs there is a massive improvment in pickup and revs much nicer.
Am thinking about giving the throttle bodies a miss for now, just gonna go for cams, pistons and group N engine managment.
