thanks very much for that infomation.

would this be one of the models that is safe then if a cambelt was to break . the belt has been replaced about 7000 miles ago.

thanks again.

That is a question I have asked myself too.

Feedback from this site, and elsewhere, has been conflicting for me, I did a serach on "interferance engine" and destructive" as well as "non-....."

Of course there is the "wait and see what happens" option, but that could be expensive.

It seems that of the 240bhp ( to 94) and 261bhp (95 on) engines, 1 of them will let the valves hit the pistions.

It would be good to see something that is firm on this point.

Perhaps the LS guru Colin Barber can comment?

I'm just guessing that you will be ok with the 240bhp motor, but the 261bhp will cause quite a bit of damage when a cam belt goes.

My is due to be changed in 5,ooo miles and I'll be doing it myself, on the back of the lexls.com tutorials.
