Wow! I got my engine back together last night at about 2 a.m.! I bought my car about 8 months ago. It ran great (I thought). I've been studying this forum and others for about a year and I decided I was ready for some DIY action! I started out with a valve job(thanks diesel giant). Every clearance was tight.. I then pulled the turbo and manifolds, cleanded the hell out of all of them! Deleted the EGR (thanks for the kit BC). Installed a pyrometer(used the pictorial thanks??) (pre-turbo in the collection flange). installed boost sensor in the extra intake manifold port. High temp painted Manifolds & valve cover (intake/valve cover gloss red, exhaust silver) They really look nice installed! Cleaned out "banjo bolts" and hoses, both of them. Put everything back together! I haven't installed my gauge yet just the sensors. BTW I can monitor a 2nd temp with my gauge. Any suggestions??

I'll post some pictures later today. I'm gonna do a diesel purge and oil change later today after work.
My point of the post is that after doing all this (mainly the valve job I assume) the car runs/idles amazing!(I was 12 errr sodas deep last night so my observation could've been a little off!) But it was so much quieter and way smoother! I couldn't believe it!!
I bought a ebay manual boost controller.. maybe next week... This forum helped me a lot!! Thanks!

Congrats and best with the car. I too have recently gotten back into the Diesel Benz hobby. I grew up in a family that bought these vehicles new back in the bright days of MB. We still have these cars in the family to this day. They were built to stand the test of time. They are a labor of love and a true pleasure to drive.

Measure oil temp with that 2nd gauge.

I know the feeling to be able to drive the car again on the open road. I've been temporarily grounded for 4 days getting the axles redone. Today the temperature warmed up into the 50s (zomg a heat wave!) and my car just loved it. I really need to find a good stretch of road where i can bring her up to 100 mph. I can feel the urge at 73 mph to go even faster. There just isn't a good place nearby to do it.

I hate to be anti-environ, but I need one of those EGR delete kits. My intake is horrible!

It's great to get projects, or portions of projects done and be able to see and feel the benefit of what you've done.

I'm in the process of repacking wheel bearings - right now actually (this is a minor diversion) and I know when I'm done that it'll drive so much better and there will be less clunking and crunching and it'll be one step closer to going to the alignment shop.

Good job

There is nothing anti environ about removing the EGR. Between the weather we've been having in the Northeast anything to heat this world we live on up is a good thing

EGR helps prevent smog and acid rain, not CO2.

There are other green house gasses besides CO2 ya know.

actually egr cools down the combustion area, lowers nox

Indeed there are, but that doesn't change things. EGR is not to suppress greenhouse gasses of any kind.

Matt you're confusing me. I was under the impression that the EGR was there to help eliminate certain green house gasses such as nitrous oxide (N2O) and into less harmful gasses.

Can you explain your stance on the EGR?

Nitrous oxide is not what your engine produces. The oxides of nitrogen that are produced don't get to the upper atmosphere, where they would cause greenhouse effects. Rather, they stay near the ground and cause ground level ozone, smog and acid rain, which cause immediate human health issues.

As the Oracle correctly points out, the exhaust gasses lower the combustion temperature.

NOX is considered a pollutant, but I do not believe that it is classified as a "greenhouse gas." The formation of NOX is a function of excess O2 and high temperature, both of which exist in a diesel engine. The EGR is intended to admit some exhaust gas into the combustion chamber and reduce the formation of NOX during the combustion process.

Regarding "greenhouse gas," the only way to produce less CO2 is to burn less fuel. Essentially all the carbon in the fuel is going to end up as CO, CO2, or unburned hydrocarbons (mostly soot in the case of a diesel).

greenhouse gasses are not a pollutant. lots of CO2 from an engine is a good thing! its made from complete combustion! so the only ways to reduce CO2 is to consume less fuel or make the engine less efficient.
