Problem is the cast alloy plate that the alternator bolts to fouls the oil filter housing. If you unbolt the housing you should be able to get enough clearence to get at the sump bolt without removeing the alternator mount. Handy if engine is still in car. I just removed both.
.... and oh dear. [xx(] That's a lot of metal on the pick up...
and in the sump....
Just one bearing had failed and spun on the crank within the conrod. Both are fubar. Engine is not an economical repair.
Oh well. [
I stripped the engine down a bit more last night. Shown here with the cam covers and intake pipes removed.
I did NOT use cam locks when stripping the engine as I have no intention of rebuilding it, I do have some but I couldn’t be arsed fitting them. I would advise that anyone considering changing the cam belt on a V6 should use cam locks.
Arrowed Green – Idler pullies, should be replaced with cam belt.
Arrowed Red – Tensioner, should be replaced with cam belt.
Arrowed Cyan – Water Pump, should be replaced with cam belt.
Arrowed Black – Cam belt pullies.
The cam belt pullies are held on with a 19mm bolt which fastens and locks them onto the camshaft via a taper lock.
When changing the cam belt I have seen some people attempt to “lock” the cam shaft via the cam locks. This is a MISTAKE! You use the cam bearing cap bolts to fasten them in place and they are not strong enough to withstand the torque generated when undoing the pully bolt. You tend to end up with a stripped thread for the bearing cap bolt.
Not good. Head off, and a complete rebuild required. I use this tool (below) to hold the camshaft. Its very awkward to get it onto the rear bank pullies in car but not impossible.
Dial guage, used to find TDC
Cam belt tensioner. As I have said before, if you’re changing the cam belt you would be mad not to re-new this as well. Its critical to the well being of the engine….
It rotates about the socket bolt circled and you nip up the bolt out of sight (arrowed) when the correct tension is achieved.
I’ve always struggled to tension the belts on V6’s as I have always replaced the plastic impellor pump with a metal type. But not the genuine GTV pump from Alfa, nooo cheapskate here tends to favour the pattern equivalent. There isn’t a great deal wrong with them, they’re good quality AFAIK, the only problem is they are slightly different externally and you can’t fit the tool to tension the belt on them. I eventually found the solution – Stillsons.
