So I have recently gotten to the end of ripping the old Buick out and replacing with an Ecotec. It runs a bit rough but every so often it wants to run like proper **** and dies on decel.

I was looking at expensive cars on carsales.com.au while I was bored and I came across this REALLY overpriced Commodore which was supposedly owned by Brock (Turns out it is!)... The seller in Victoria wants $1.5 MILLION (Yes you're reading that right!) for an S Pack with some plaques on the...

Hi all, I've lost one of the bolts for my plastic rocker covers. Just wondering how people go about getting new ones? All I can find is people saying replace all of them when I change the gasket, not the size and thread pitch. Also what are the plastic things that slide into the grommet things?

Hello all, I recently broke the spider gears in my diff (Most likely) and my mechanic said that it’s cheaper to find a new diff from a wreckers than to repair the gears.? So I was wondering exactly what diff is in the series 1 VX Berlina V6 Auto’s? On another note what is a stronger diff that...

Hi all, bought a supposed VY 3.8 ecotec from the wreckers, but it's got a different sump from the VY (no gearbox bolts at bottom) and also had different headers from my VY ones. The engine number is VH841229. Any idea what it's out of? Cheers

Hey Guys, I just bought a hardtop for my VS Ute and I was just wondering how to mount it. It’s from FlatTop I think. With small brackets that look like they need to go through the rear parcel shelf piece that the tonneau cover would clip into in the front. Thanks in advance.
