mounting block looks mostly clogged up.. needs to be removed and cleaned out along with the rest of the EGR piping and sensors.

That IMAP sensor looks bad too. It needs replacing.


as far as the photos go .. so far it looks like mostly just excessive soot due to engine problems and not coolant or oil so much.

Could it just be a lot of soot like the freight train effect you mention and not be engine issues? If it is engine isssues, what causes this soot build up other than EGR clogging up?
