a NON interference engine?
There are numerous threads I've seen on the web and, some say a red block engine is a safe, i.e. non interference engine and others saying their b200f had damage.
Is it a case of strip it and look or is there a definitive answer to interference or NON interference?
Many thanks Ken

So... I said I would post my results of my timing belt change, and.... in answer to my original question... the b200f is 75% non-interference (in my case.)
Number 3 cylinder has zero pressure on the pressure test after the belt fitted.
At first I think I was a tooth out.( It's easy to do, the marks are not exact)
It ran really bad and noisy till I re timed the belt, It runs much better now but, there is a knocking noise; like a really noisy tappet makes.
So it's head off and, replace the damaged parts or....head off to a dealer to buy a replacement car. By the time I've done that and sold on my tank I could have repaired her.
Thanks for all the helpful replies, much appreciated. Ken
