  • cambelt age?

    Hi all I have a number of nos Unipart cambelts for the O seies. I bought them years ago and they have been stored in their boxes in my garage, out of the light. I was going to fit one but then started thinking of the age of them-does it matter? There are some Unipart ones on ebay and ebven if you buy a new aftermarket one they don't seem to be dte stamped, so how would you know the age anyway? Any views?
    TIA

          I know the 1.6 doesn't wreck the valves but I thought the two litre O series did?

            Yes that is right Russ. None of the two litre "O2" series engines are safe, not even the Turbo.

              So witch one is correct if the cambelt goes on the 2.0 turbo does it hit the valves or not ?

                Yes,the valves get hit!
                Out of interest did the pistons hit the valves on the original princess type engine?

                  i have a turbo and have shattered the camshaft on several occasions and have been able to fit a replacement cam roadside and carry on driving, albeit with a rescue mission from one of my brothers to get a spare camshaft and followers.. was usually the follower breaking up.. but never a valve... regards ricky

                    Wouldn't it be a bit easier for you to replace the cam belt now and again

                        Is it right that turbo buckets are stronger?

                          they used to be slightly longer than the std efi ones.. made them more reliable as well.. regards ricky

                            They must tolerate higher RPM then? As I understand the bucket issue is that when revving at over 6000rpm the cam flexes slightly allowing the bucket to jump off the valve spring and turn over causing all hell to break loose

                              I think early montego turbos had cast buckets - later have steel ones inc all maestro turbos. Had a similar failure but valve collets worked lose and dropped an exhaust valve. I now have fitted Triumph Spitfire 1500 uprated valve springs that I'm hoping will keep things together?
