Are there any tricks of the trade for fitting the crank timing tool on my 1.2, 12v, CGPA please?

I can't see or feel what I'm doing when reaching up from underneath.

Thanks very much.

Probably easier to take the intake manifold off to gain access from topside.

On ours it wasn't helped by the white furry corrosion of the block's alloy, including down the hole that the crank sensor and crank locking pin go. Took ages to clean it out enough to get the pin fully in, even after manifold was out the way.

Thank you for your replies Breezy_Pete.

Was the engine out of the car?

No, in car.

Did the crank sensor come out without a struggle? Or are you not there yet?

Got back to working on car yesterday. After undoing manifold screws there was enough flex in the hoses and harness to move the manifold sufficient to give access to the crank sensor (thank you again Breezy_Pete).

The sensor pulled out without a struggle and the locking pin slid in likewise.

Day off today. Back to working on car tomorrow.
