M272 timing chain stretch test?
Hi,
I have the engine out of my car for the balance shaft gear issue and I thought I should check the chain for stretch. I haven't got the engine apart enough yet to see if there is significant wear on the chain but I was thinking that if there is negligible wear and stretch I wont bother replacing it (110,000 km on the clock).
I have access to WIS/ASRA but cannot find a procedure for determining chain stretch. Anyone able to advise?
Thanks

Thanks, I'm assuming you're referring to the valve timing method. The only issue I have with that is that there are no clear values where a chain replacement is recommended, or did I miss that?

Why don't you just help the community by giving the answer. The cryptic crap you spew is a waste of time. You either have helpful information or not.

With all parts removed as mentioned above to gain access to these lines which got to driver side tutbo
Line to driver side turbo. I replaced both lines to that turbo as they were brittle to touch. Caution as male part with o-ring may break off inside block. Not to worry what i found to work for me since i had it was piece of wire hanger with one side bent like an L and the L part of the hanger inside the broken piece in block and carefully pry towards the radiator and a lil wd40 to lube oring and popped right out. NOTICE THE ONE MOUNTING HOLE FOR EACH LINES. Others may have 2 holes to mount.
