Astra H Z16XEP
Right basically im timing me car up and I cant seem to figure out how to get the tensioner right, I can tension the belt fine how it should be done, tighten the torx bolt then use 6mm allen key to rotate it anti clockwise until it sits in the locking position then tighten the torx bolt fully
BUT!! the tensioner keeps moving back and forth when engine is running also making the belt move right to the front of the pulleys making it rub on timing covers making a screeching noise??
I have tried loads and loads to get this right done it 30-40 times now, but still the belt slips towards from of pulley and rubs I didn't have a locking pin for the tensioner and so just removed it hoping I could just put it back on (its how I have been doing every car for years now) but this bloody engine will not do it!!
I literally don't know what to do now im stuck, does anyone know how to do it properly??
the pulleys are not bent etc.. as iv changed them all to make sure, blet stays tight! but its just not working, and starting to take metal off the block where the tensioning little stick has scraped on it...some help really appreciated ASAP!
