Hi,
In the process of replacing the cambelt on a 1996 164 3.0 24v and two questions:

1) Where to fine the timing mark for the crank? Have been searching and can't see anything, except the tooth-free segment for the crank-sensor.
2) Have noticed there is zero air-gap on the tensioner piston. Anyone ever had this before? Was definitely one there when I changed the belt last time.

Worth noting is the current belt has done less than 40,000 miles but it is about 8 years old and looks a little aged as a result. Glad finally got round to changing it now before anything nasty happened.

Cheers

crank pulley has a line scribed on it that matches up with a triangle shaped pointer on the block, pointer is nearly at 12 o clock when viewed from the pulley. Search '24 valve timing belt change' and similar for photos. You may have zero air gap at the moment, but go ahead and run the motor. The gap will grow while the motor is running.

Thanks. Reassuring about the air gap. Will have another look for the pointer. Found it last time changed the belt. Maybe I just need glasses now :-0

The white mark on the pulley.
To set upper position of the piston can be used ( through the spark plug hole )
