My vw TDI mechanic "makes" me wash my engine every 6 months. Says it won't hurt the engine at all and that it makes it easier to watch for leaks or any problems.
I want to do the same for my truck but am a little nervous. Any thoughts?
Washing engines, espessially with power washing is not my style.
I'd rather have dirty running engine then clean with some electrical gremlin and not working.
And your VW mechanic, it sure will help his pocket when things go wrong and he will have clean engine to fix.
