W123 Turbo Issue
Hi All,
I first posted on Sept 24 about my 1982 300 TD problem. To recap, one of the oil hoses ruptured while I was driving at 65 mph on the Interstate. I pulled over when the engine started to lose power and stopped the car. After repairing the hose and adding six quarts of oil, I tried to restart, but it would not.
I had the car towed home and here it sits. It easlily started cold, but it ran roughly and smoked a lot. I suspected engine damage from the lack of oil, so today I removed the valve cover and inspected the cam, liflters and adjusting nuts, they all looked fine, but the valve cleareances were off - too tight. I adjusted them per specifications, and reasseambled the valve cover. It started right up and ran smoothly without any smoke.
I took it for a test run around the block. As the engine warmed up, it lost power, and I noticed a whine from under the hood. I suspect that the turbo is responsible for the power loss. I had previously checked it by spinning the suction wheel when the engine was both cold and hot. It spun freely, but that is as far as I got with it.
I'm now assuming that the cylinders were not damaged by the short time the car was very low on oil. The problem seems to be the turbo.
Any thoughts or recommendations?
Regards,
The Chief
