Intake manifold cleaning
Intake manifold cleaning
(02-14-2009, 08:23 AM)Gurkha Is it necessary to clean the intake manifold after 80,000 miles in a turbo diesel OM616?
If the EGR and CCV are still hooked up it's got some gunk in it. Judging by the amount of buildup I have seen in ones that have 200k - 300k miles, you would benefit by cleaning it out. Not necessary but it couldn't hurt performance.

In that case it will just have a thin oil film. Nothing to worry about and no benefit to cleaning it out.
Many thanks FI, I was getting a bit paranoid. Problem is to open up the intake tract means touching all the turbo plumbing which I would only do it if its truly needed. It was quite easy to open up the intake tract of the N/A OM616 that I had earlier but this one looks to be a royal PITA.
