Hey, I've just changed my harmonic balancer due to a little accident I had with it. [See pictures below] (The harmonic balncer outter ring has come loose from the main part and moved towards the timing chain cover, grinding against the timing marks.)
Now I want to set the cam timing again as it has been only set at a guesstimate in the past because of the harmonic balancer ring slipping(so didn't know for sure where TDC mark was).
Currently when you look level with the head at TDC, the timing mark on the cam is just below the top of the head. Now gregories says it can be level or 3mm above, so I've moved it back a gear and now it's about 3-4mm above the head. Is this where it should be?
Fairly commen problem with the harmonic balancer, same thing happened to me. I've reset cam timing after the head off with the mark nearly level but slightly up and seem to think it's running quite well compared to what it was before doing the head gasket

Put your cam timing forwards a gear so it's just below the head. You will probably find it will give you a bit more go.
I found that with it up above the head, it makes the exhaust louder and seems to struggle more but probably has more torque. But when it's just below the level of the head like it previously was, the revs picked up much quicker and it was definately faster. I'll be putting mine back to that spot as soon as i get some spare time.
