In this video we dismantle and diagnose massive engine failure in a 1.9 TDI PD. In the last video https://youtu.be/_dNTMqf5nYM we converted the Caddy to run on veg oil, after testing it for 500 miles, fuel leaked into the oil.
This filled our crankcase and caused problems. By examining the engine’s tandem pump and camshaft we can see how bad the damage is. While we are at it, and have worked out how to remove the valve cover, we go on and assess the condition of the intercooler, unit injectors, ERG valve and turbo.
Hopefully this video will be of use to you if you have a problem seal in the tandem pump, or need to take apart a pump duse engine to find faults.
The engine here is a VW BLS which is also very similar to engine codes: BJB,
BXE. These appear in lots of VW, SEAT, Škoda, and Audi cars, but this one’s in our Mk3 Volkswagen Caddy.
