.....yes another one.
I took the cover above the EGR/Inlet manifold of today.
It must be the easiest thing in the whole car to remove.
I last did this at the end of April, and had cleaned it out as best as i could without dismantling it further.
Anyway inside was sooted up again.
Looking inside the manifold and figuring out the airflow, I think that the exhaust flow into the inlet manifold can take 2 paths.
One is the half round cut-out in the Inlet Manifold, and the other way is up into the cover and the exhaust flog joins the clean air in the cover.
So how to block the exhaust gas flow.
I have fitted 4x 40mm repair washers (40mm diameter, 6mm hole in the middle, about 2mm thick, mild steel, BZP) loosely into the area just above the EGR outlet. They do not fit properly.
I choose 40mm washers because that is the size (width) of the opening.
They do not in any way completely block the exhaust gas flow, but they must slow it down.
The 40mm washers cannot be sucked up into the inlet manifold, I checked.
The next step is to bend some 6 more 40mm washers at an angle of about 30 degrees just above the centre hole.
Then they might fit the shape of the inlet a bit better. I will do this at work next week.
Just before re-placing the inlet manifold manifold i sprayed some Brake Cleaner onto the sooty deposits.
When the engine finally started, it rev'ed right round into the red zone on the tacho'.
I switched the engine off, but it continued to run for about 10 seconds, with the rev's falling and then stopped.
Thankfully it started again with no nasty noises.
Driving it shows a small improvement, and it seems a bit more lively, but I have only done about 20 miles.
I will report back when I can, and include photo's.
Next step is de-cat. Anyone on the Wirral had it done, and if so, where please??? Thanks in advance.
