Do VWs have this problem? I have a diesel
Mt Grand daughters older Jetta did this .
The TDI engine will eat valves if the timing belt breaks. I had a 1990 GTI 16V that did it, but that was after I sold it to a co-worker who I warned about this tendency, but he was one of those drive it until it breaks types.
I replaced the belt every 35K miles.
Absolutely. The diesel has no combustion chamber other than the thickness of the head gasket. IOW...no room for both the piston and an open valve.
Better check when you last got a timing belt.
