Can I use the JP Timing Chain set in my engine?
The JP Timing chain set can be used in all pre-serpentine engines.
The JP timing chain sets can be used on all the Rover V8 engines using the pre-serpentine (V-Belt) front timing cover and ancillaries. The reason for this is that in the later (approx. 1993 onwards) Serpentine cover there is not enough space for the slightly wider JP timing chain set.
Another issue on the Later, 1995 onwards, 4.0, 4.6 litre Sagem and Motronic engines is that the top timing wheel is machined especially to work with the cam angle sensor. Therefore if the JP timing chain set did physically fit the engine management system would not work correctly as it would be missing the cam angle information.
