Re: What if you don't change the Cam chain at 35K? ('99 GTV)
Congrats on the GTV Diveboy.
Basically, what happens is that you spend the next 15k miles being very, very paranoid. I certainly wouldn't like to take on sods law by chancing not getting it done, especially as it's due on mileage if it hasn't been done. When you consider the change costs roughly 4 times less than the repair if it does go, I'd want it done just for peace of mind.
Out of interest how long ago was this alleged 20K cambelt change?
