Thought I had better ask the question, is the 4.2 V8 supercharged engine driven by a cam belt or timing chain?

 

I have nasty experience of cam belts and thought they were a thing of the past however, reading a advertisement for an XKR I came across the sentence 'recently had cam belt replaced' which sent shivers down my spine.

 

All the Mercs I had were chain driven and offered no worries

I am fairly certain that it is a timing chain on the XKR, Kenny.

 

My S type has a belt which has to be changed at 105k, and considering I do less than 7000 miles a year and as the engine has only done 35k miles, I will either be dead or have sold the car/stopped driving.

 

Regards,

 

Peter.

Thanks Peter, still want to know to be sure and put my mind at rest, suffered severe engine damage many years ago with those damn pesky cam belts and don't want it to happen again. If car manufacturers persist in driving the motor with cam belts then they should at the very least install non interference engines.

Kenny, 

 

I googled XKR timing chain and  it came up with some for sale.  I know what the S type has as I am able to see it [i think?].

 

I come from the era when all you needed in the toolbox was a lump hammer and an adjustable spanner, and the only drive belt was for the dynamo!

From what I have read its a chain Charlie which gives me some piece of mind however, there is always an however, there appears to be a stage where the XKR used some form of plastic tensioners which was not a good idea and they changed to metal. I know need to know at what stage to ensure my model is equipped with the latter tensioners

kenny i know what your taking about. mines the same after so many miles it needs tightend up. will try to find out over the next few days for you and me. will be in touch charlie

Ken you have the same engine in yours as I do in my str. Therefore it has a timing chain, metal tensioners and the steelined cylinders instead of the nicosil lined ones so you are fine
