Hi all, first post (though I'm sure I've posted here before!).
I have an '03 Astra 2.2, timing chain snapped and was duly replaced along with some new valves. The car started fine (eventually) and ran until the cam carrier cap on the exhaust cam at cylinder "fell off", it looked like the cam was slightly bent.
During this time it was burning quite a lot of oil (large clouds of blue smoke above 4k) and the inlet was covered in ti too.
I've since replaced the cylinder head with a known good one and cleaned the inlet as best I could at the moment, I'll not get to the workshop til Friday to get tools, but I still have chronic oil usage (think 1l in 2 days/50 or so miles) and flat spots through out the rev range.
At first I thought it could have been a problem with the dipstick but I've measured in the correct amount of oil twice now and the dipstick would seem to tie in.
I'm at a bit of a loss as to where it's all going wrong, I'm starting to wonder if something disastrous has happened to the bottom end in the timing chain incident. Anyone got any wisdom they'd share? It'd be nice to go somewhere without it costing more in oil than petrol!
Cheers
