Ordered camlock blocks, will be with me wednesday, so yesterday decided to have a go with engine dismantling. But leave the cambelt on. But after takink covers off, saw marks on both gears and variator, and took the belt off. Stripped everything off just need m13 ribe bit, does screwfix sell it, or halfords? To be honest, i love alfas engines ( 1.6), everything was stripped in just 2 1/2 hours, can't see why garage needed 5 hors to do cambelt variator and waterpump. I bet it can be done in 2 hours by me. And chaps from garage didnt screw all the screws in covers back in. and plastic bracket screwed to water pump had snapped ( waterpump metal).
Thats my progress so far.
Checked waterpump, its plastic, but seems like new. That couldnt have caused overheating.
