2005 mini cooper s timing issue
Hello everyone. I cant seem to be able to set the timing marks on my mini. I think it skipped timing so i ordered a new timing chain and guides. Im trying to get all marks to align before taking everything apart but i cant. When cam arrow aligns with 1 dark link on chain, cyl 1 is all the way down instead of up. Any ideas? Or suggestions? Or how can i get it timed properly tonmake sure that when i take everything apart and put back together the car will start

If it skipped a tooth, you won't be able to get the marks lined up before you take it apart unless you get it to skip a tooth back (not likely). Best bet is to set the crank at TDC, pull the chain, turn the cam to line up , reinstall the chain, tensioner and new guides being sure that all points line up correctly with the chain points. No other way around it.

I had the same question when I put my timing chain on recently. I had the timing cover and the oil pan off, so I could see that with the colored links lined up to the arrows and the cam locking tool installed, cylinder 1 was nowhere near TDC. It turns out that using the cam locking tool and aligning the links to the arrows puts this engine with all 4 pistons at equal height. So your #1 piston wont be all the way up, but it also shouldn't be all the way down. All 4 should be at the same height. This is the only engine I've ever heard of that you don't set timing at TDC so I was really surprised.
