Hi Fellas. Story so far.... My 1.9dg was fully rebuilt last month. Initially et up as Haynes says with two turns on the tappets positive (against the retainers). Has been running fairly well, especially after 300 miles. We went in the garage for the initially check over and oil change. All was good. Put 10/40 in and adjusted the tappets to 1.5 turns positive which is more recommend. However, she was running very lumpy with some intermittent and loud knocking noises. We drove away and about 100 yards up the road the oil buzzer came on but I continued as I assumed the oil was still running around the engine and hadn't had time to trigger the sensor. After driving for 1 mile, the engine cut out mid gear change and seemed to stick. We managed to turn it over by pushing in gear, oil and coolant levels are good and we managed to turn her over via the ignition but again, very lumpy. Is there any experienced folk who could gibe some much needed advice! Cheers

1.5 or two turns should make no difference to oil pressure
check the oil pressure, buzzer could be a faulty wire but you need to be sure.
why 1040, it should be 1540 mineral oil.

You need to have the oil pressure checked as a precaution before you drive it anymore. Reset the tappets back to 2 turns that is where they are supposed to be. 10/40, 15/40 will make no difference it only means the oil gets around the engine quicker when it is cold with 10/40.
