The engine has got no PCV valve, nor EGR as is it an European engine. The breather from the valve cover just goes directly to the intake, and it's not clogged. I ran the diesel purge from a bottle, but it didn't make any difference.
Will try loosening one and one fuel line to find the troublesome cylinder. If air is the problem, I would think it would just be running rough, not the same cylinder all the time, right? |
Concerning the Injector Heat shields; while the should be changed for test purposes they do not need to be changed.
Also When I did the Injector Rebuild on my Volvo Diesel I did not realize there was heat shields that needed changing. I drove the car like that for 1-1/2 years until I managed to drop a Screwdriver into the Timing Belt of my ideling Engine.
When I got the Head Gasket set it came with new Injector Heat Shields. At that point I realized they should be changed.
re-using the Heat Shields caused no issues during the 1-1/2 years I drove it.
In post #4 in the thread below there is a thumbnail pic. The Idle Fuel goes through the #14 and #15 holes. My Mercedes shook a lot at idle and rebuilding the Injector removed about 1/2 of the Shaking issue.
I attribute the Shaking to the fact that those holes were completely plugged with carbon.
If you end up pullling an injector/s look and see if you can see if the hole is plugged.
