Oil pump drive sprocket replacement??? Help!!
Hi guys, wondering if anyone can shed some light on where I can get a replacement for the oil pump drive sprocket?? My s3 developed a rattle the other week(very tappet like) but as I've already done these a few months ago I suspected maybe a dud oil pump or blocked pick up pipe causing low oil pressure and maybe a rattle tappet or camchain tensioner because of this!
After whipping the sump off to check these I discovered the remnants of the oil pump drive chain tensioner in the sump and the chain rattling its tits off and luckily still driving the pump(by the skin of its teeth...literally!!) great...I thought new tensioner n a quick solve! Wrong!!
Decided to just bite the bullet seen as tho i'm in there and replace the pump,pick up pipe,tensioner,crankshaft oil seal,chain and both sprockets as it seems to have chewed the teeth a bit. But it appears that audi want me to buy a full crankshaft because they don't sell the top drive sprocket separately!!? Please help...there must be a remedy to this surely as a new crank is Ā£500!!! My elsawin workshop manual says this part is removable and is heat shrunk onto the shaft...???any ideas people...any links to where I can purchase this part...buying a complete crank seems very far fetched for the sake of a sprocket!!! Thanks in advanceš
