I've had a family friend change my cambelt on my 57 plate VRS PD170 on Saturday, when I picked it up it was a bit smokey and had a very strong smell from the exhaust. I did a bit of research on the Internet and found out that I needed to check the torsion value on the intake cam. Sure enough mine was reading 2.63degrees and the tolerance is supposedly -1 to +1 so I took it back and we adjusted into tolerance. It ran fine after this and the smoke and smell had gone.

Until now! The smoke is back when at idle along with the smell. I've checked the torsion value and it's still at +.35 which is what we set it at previously. I'm beginning to run out of ideas.

Does anyone know what I can check next or know what might be causing this? If I don't know soon I'm going to have to take it to my local Indy.

Many thanks

Did your friend use the correct timing tools to lock the cams & crank etc & set up the belt tension correctly? It sounds like to me the timing is a tooth out.

Yeah the correct pins and Crank locking tool was used. I think I'll probably get him to retime the engine and try again.
