Is there an easy way to check the cam timing ?

I've had a remap recently and it didn't go as planned - one of the possible causes could be cam timing, so I'd like to confirm all is correct.....

Car is an 02 STi UK

Ta,

Or a guide to checking ?

 

Mine didnt perform well on a RR once so I also checked this.

Obviously the first step is to remove the cam covers, sounds easy but there isnt much room to play with. Some advise removing the radiator.

Once inside the job is pretty self explanatory, make sure the marks on all of the cogs line up with the marks on the case behind. You will see what I mean when you get there, thats the easy bit.

Good luck!

 

I assume you have VVT heads ? in which case the intake cams are ECU controlled, and only the exhaust cams could be out.

Did the person mapping your car adjust the intake cams to optimise them ?

Can you give a little more detail about what was, or wasn't happening.

With regard to adjusting the cam timing, checking that the belt is fitted correctly is just that, but the actual cam timing can, and often is out by miles.

Checking the "cam timing" is very involved, and requires special equipment, and someone who knows how to use it, and ideally, it needs to be done with the engine out.

Adjusting it really needs adjustable cam pulleys, although it can be done without, GrpN style, where the pulley locating pins are removed, and the pulleys are bolted up very tight. I wouldn't recommend it for a road car though.
