Cam locking blocks - fitting
I am part way through a cam belt change on a 2.0l engine. I haven't yet taken the old belt off so cam timing has not yet been disturbed in any way.
I set tdc and located the cam locking blocks. The inlet one fits perfectly but the exhaust one is just slightly off as you can see in the photo.
So, should I (a) use some pieces of lead packing under the right hand end of the block and against the cam lobe to secure the camshaft from rotating, or (b) turn the camshaft slightly to settle the block properly on to it. I reckon the cam would need to be moved 2 - 3 degrees.
The belts have been done before so possibly the cam has been a little out, or would there be that much movement in the belts anyway? The engine was running perfectly.
Oh, and it is really annoying at this stage to find I need longer unobtainable bolts for the cam locks!
