Hmmm, sounds like it would be a major bummer to blow a seal. How are the odds on this? As for the oil separator, it's the apparatus in the center of the air filter housing that the breather hose attaches to? What can go wrong with those? Thanks again, Jim |

Blow-By curioisty questions Basically its a quick metric of general engine health. If theres tons of blow by, its generally a negative thing, if there isn't too much, its generally positive. How good or bad different levels of blow by are is uncertain. Cars that have lots of blow can run great, cars with no blow by could have something else wrong.

Timing is not too difficult but you will need the tools to do it. A search on "drip method" will give you an idea. A good shop (someone familiar with MB diesels) should be able to check it in about an hour's labor. On another note, a leaking EGR valve might cause this but I'm not sure how much. Cleaning it to get a good seal, then disabling it with a BB in the vacuum line (for testing purposes) might resolve furthur problems there.

Ain't no way you should load in a few gallons of veggie without a separate tank to heat it in. Now some bio will flush things out like metamucil. Caution, though, to take care of fuel filters. Bio clogs things for a while.
