Thanks Scorpian. This could possibly be the foremost contributor to carbon deposition.
Has anyone used a blanking plate to isolate the EGR assembly completely?
That would be a much easier option as the assembly is held in place by only two M6 bolts.
The intake manifold on Ford Tdci diesels can be easily accessed by removing the valve train cover. I am seriously contemplating use of carb/choke sprays/scraping off deposits using a screwdriver to clean off the buildup..
Attaching a picture of cylinder head for reference. The four largish round openings at the top lead to the intake valves |
