Could only spend some time on the car the last weeks. Got a dealer´s license plate to make a short test drive today. Had fitted a thermoswitch with lower settings and refitted the cowling. Short distance and back, again water thermometer close to the red area. Will see tomorrow, if air is out or not. But, when hot, waiting at the garage door to open, it started knocking
at idle (oil pressure very low at idle, but no warning light). Have the high volume oil kit, and oil pressure rises with cold engine at fast idle quickly over half of the gauge (do not remember, half is 30 psi or ?). Driving distance was too short to see where oil pressure goes with warm/hot engine. Knocking disappears when reving and comes back at idle. Must admit (shame) that I did not check the crank bearings, so I think I will have to take off the sump pan and check them. Are all of them suspects or more rear end or front end ? When I pulled away with cold engine, there was a kind of metallic shattering (like a loose metal panel) and at the first start now the BW65 had some problems to engage D or R, but I think, that´s because of the long standstill. Gear changes are fine and body roll (with new GAZ shocks...) is impressive. When I bought the car, I thought it had orig 139 tkm, but in the meantime went through all the bills from the owner with the longest ownership (around 30 years) and it has 239 tkm. Ok, 1974......
The service history from 35 tkm to approx 210 tkm is impressive, a lot of oil changes.
Have setted CO to 3,5% with the Gunson and have 5-star fuel in, but I think, lean knocking is not at idle, or ?
