diesel running fast food fuel

I've had several engines apart that we're running on some manner of 'Bio-Diesel' ick that made for unbelievable sludge in the crankcase.

Beware.

Couple factors there, one many of the 'conversions' are done on already high blowby engines.
2 they are often done by people who don't really do scheduled oil changes.

Once it polymerizes that stuff is so hard to get rid of, I saw one that took 4 trips through the hot tank, and still wasn't quite clean.
Seems worst in unheated systems.

Almost impossible if you look at how the timing works.
Not that it makes a huge difference.

You are when you claim "it runs exactly the same."
While you may not be intentionally lying, you are wrong.

Ok....I can't tell the difference in the way it runs.....except for the stink of fryer oil....which I thought I would like.....but hate.

I did lie when I said the car is unmodified. I have the timing forward and the pump turned up a little bit.
