On the subject of timing chain problems... Does the timing chain get it's tension from internal oil pressure? I recently punched a hole in my sump pan on a road I SHOULD NOT have traveled. ( did stop in time to watch the rest of the crankcase oil drain)
The engine never over heated, but it did stall out. Got towed home, replaced pan and oil, and still no oil pressure. Dropped pan again to find that I broke the pump as well. Found a NEW 'old style' ( my Benz is a 300D NON TURBO ), installed it and restored to excellent oil pressure.
PROBLEM: Car barely started on ether, ran rough and blew black smock. Test drive revealed total lack of power( eng ran great before the rock incident)
Question: Could the timing chain have jumped a tooth on the sprocket due to loss of oil pressure causing the tensioner to fail?
Please advise... before I order a new timing chain or A NEW ENGINE THX! NKB
