I had a new head gasket on my CS 2.3t last week. Since then it's been running really lumpy, I'm getting lots of vibration around 75mph (& over!)& it doesn't sound right when idling.
Anyone got any ideas on what might be causing it? I'd appreciate any replies.

Did you change it yourself?

Did you get the inlet and exhaust cams timed exactly right?

It seems to be common practice to get one of other of the cams 1 tooth out. It's not enough to damage the engine (contacte etc), but does wreck the idle and low speed running.

Doesn't normally hit the high revs much though.

I had it done at by a Saab specialist not far from where I live. I'll take it back but I can't afford to throw too much cash at the problem. I just needed to know whether it's their fault or something unrelated. It sounds like it could be something they disturbed.

Looks like your going to be right twice in a row Andrew[/b]
Possibly, we will wait and see.

I was very careful today when I took the top off the 900 S 16v today.

I had to set TDC twice to get the cams in the correct place (notch aligned aith mark in bearing cap and TDC and cam wheels) as the cams are half engine speed and the 1st time I got TDC the notched were 180 degrees out. Doh!.

Sound just like mine
They did get both cams aligned / timed properly? I have heard of people having problems (without valves hitting pistons) when one on the cams has been 1 tooth out and causing low running problems.
