From potential rebuild to repairing a chafed oil pressure sender wire.
Another reason VWs are amusing to own & operate.

This is the second time in a row! I just went through the engine cutting out under load and was sure something catastrophic happened. I parked it for months then one evening when hooking up the battery tender I looked over and noticed that the plug had blown out of the carb! Found it in the engine bay, popped it in place, and drove off without incident.

Yeehaw! How much pressure does it have at hot idle after a freeway flog?
VW spec'd the oil pressure to be somewhat lower than the standard 10psi per 1,000 rule of thumb. Betley specs at 2,500 RPM and engine oil of 160°f, (lazy town driving,) are 42psi when new, and 28psi when worn out.
From experience, an old engine that makes 50psi cold can still drop below 5psi at hot idle and be perfectly healthy.
