(03-09-2009, 08:41 AM)winmutt Grats on the new ride. No more crank slap
Just nailing injectors. I'm thinking of rebuilding them with the 265's out of my AAZ injectors.
Got the valve adjustment finished, 8/10 valves were very tight, 1 was OK and 1 was loose. Glowplugs were changed to Bosch and the holes reamed; All were Beru, only two worked properly, one had the glow point halfway down the plug and one plug was broken off and carbon frozen in the hole. Luckily all it took was a crank with the starter to blow it out.
While repairing the vacuum lines, I tugged on the shutoff actuator's hose and found the whole injection pump was loose! It worked out fine though since I planned to adjust the timing to 26*BTDC anyways.
It still shakes the whole car at idle, nails a little and smokes gray at WOT. Hopefully injectors will take care of that.

It was sold at "Southeast Region" Auto Auction, twice (93 and 98).
It shows 146k miles on the odometer right now but was reported with 113k in 1993, 145k in 1996 and 178k in 1998. (05/17/2000 and every one after in Florida lists "Exempt from odometer reporting".) That works out to a 10-11k miles/year average, which means it has about 283k miles! Looks like I need to pull the cluster and look for signs of odometer fraud.
Hmmm.... The car is mine so there really isn't much I can do about it.

. Sucks about the odometer, I had a W201 odometer go out on me at 138k. I was curious does the 82 300D use a mechanical oil pressure gauge? It seems my problem came from the oil line going to the gauge exploding and oil getting in the cluster.I'm curious as too why your idle is so rough, when I got my 617 it shook like fat sugar mama but after the valve adjustment it all quieted down and the idle leveled out to a steady humm.

(03-13-2009, 01:15 PM)Kozuka I was curious does the 82 300D use a mechanical oil pressure gauge?Yes. W115, W116 and W123 use mechanical. W126, W201 and later use electric.
Quote:I'm curious as too why your idle is so roughIt runs a hell of a lot better after replacing the glowplugs and doing a valve adjustment. Injectors should cure the nailing and rough idle.
Progress today
Resealed the valvecover, for the third time. I finally got it to stop leaking (Lost a gallon of oil the first round).
Replaced the disintegrated shifter bushing. The other one is in so-so shape but it stills works. No more sloppy shifter.
Found I have a coolant leak from the bypass hose. (For future reference: 42mm ID, 54mm OD, 40mm length)
Tonight I'm going to repair the odometer and paint the needles (If my old bottle of paint hasn't hardened). Since the actual mileage is unknown and the currently displayed "146K" miles has been proven falsified, I'm going to reset the odometer to 000,000 for a fresh start.
EDIT: Wow, this tri-gauge cluster is even more charred than my 240D's! Looks like I need two good ones now. The speedo's tamper resistant screw coating is broken and the numbers have been cleaned, confirming that its been altered.
EDIT2: The odometer repair is done. I'll paint the needles at a later date since I must replace the gauge cluster anyways.

The shake was reduced from moving the whole car to annoying vibration. However, while adjusting the rack damper it smoothed out perfectly for one brief second then went back to shaking. I wasn't able to make it repeat.
The odometer works beautifully (I've put 50 miles on it already) and the speedo matched the school zone radar trap at 30mph.
Next steps: Obtain a temporary tag, get smog tested and register for plates so I can (legally) drive it.

New (used) 265 nozzles are installed and set to 140bar. One of them nails a little so I'll have to figure out which one and redo it.

They both got their instrument clusters fixed.
The 240 got jumper wires to the chassis ground and to the climate control light harness for cluster illumination (With the trace cut to prevent a short).
The 300 got a ground jumper to chassis, ground to cluster light ground wire and a bridge between the main plug light posts to bypass the rheostat and its charred traces.
Now I can trust the gauges again, but the 300's fuel gauge is still questionable.
Both got a Diesel Purge and primary filters. It helped the 300 a bit but made no difference on the 240. The 300's primary was filthy, as soon as the tank is empty I'll clean the strainer.
Found the nailing to be the #5 injector. DP didn't make a difference.
Next weekend, engine mounts.

I removed and retested the #5 injector due to nailing. It popped at the right pressure, has a great spray pattern and doesn't dribble. Tried swapping delivery valves and #5 still nails. I listened to the injector lines and pump with my stethoscope and found #5 has a much different sounding injection "thump".

I replaced the leaking water pump and moved the bettery to the trunk using 1/0 gauge cable (New thread on that later). It sure frees up quite a bit of room in the engine bay! The sacrifice is the loss of my spare tire, however in 6 years I have never needed a spare (and I have AAA). The battery tray was rusted pretty well on one corner but luckily the body is undamaged. The trunk has surface rust all over the place, plus a 3" hole in the left corner of the deck. I buffed off all I could and used two cans of undercoating inside and out.

Yes. It goes to the two control computers you see on the right and the blower resistor block in the engine bay. Mercedes designed it very well, they kept the different systems in their own individual harness instead of throwing it all in one wire bundle.

Probably never. It will likely get upgraded with S600 internals when the time comes.

Boost turns out to be 9psi (as I expected). I must be spoiled to my VNT, boost builds painfully s-l-o-w.
EGTs get up to 1250*f by the end of a 0-60 run. EGT and boost are 700*f and 5psi cruising at 70mph, same as my 240.
The gauges are 30psi for boost and 60psi for EMP.

Where did you get the pillar pods? I've been looking for pods with the correct mounting angle and those look like they are the correct.

Also on the subject of drilling into the manifold for EGT, when I drilled mine I did it while the engine was running, that way the exhaust pressure will push the metal filings out instead of them entering the turbo

Got the diffs swapped tonight. The 300D now has the 240's 3.46. The 3.46 stayed sealed since it has oil less than a few months old but the 3.07 got Mobil 1 75w-90 synthetic. I didn't have time to swap the speedo so I didn't bother taking it out for a run.

Unfortunately, it "passed" emissions with 37% opacity at 50mph. I really only got away with it because I used to work at that shop.
The EGR sludge in the intake must really be choking it off. I installed a scratch-built boost controller but the spring I had puts the boost at 18psi at its lowest setting. Even with that much boost it can't get enough air ingested.

what a great idea... if my wife didnt need any kind of ventillation, i'd prolly end up doing something similar... I just roll down the windows when I need air, but shee doesnt like the wind noise or something...

The driveshaft support and shifter bushings went in without the slightest hitch.
The M-pump project stalled due to an oil cooler hose fitting that stripped coming off.
I should have put the tierod in the 240 instead. ForcedInduction

That also shows that a manual (or lockup TC) would be good for about 11mph on the top end at the same RPM, my 240 could do 107mph at the same RPM with the 3.46.

Did a quick Italian Tuneup tonight. Top speed is 96mph@4500rpm, though it took a little while to get there with only 88hp. EGT topped out right at 1250*f with 9psi boost (but its raining so that lowered it a bit). The nailing is noticeably better which leads me to believe it may just be from carbon buildup.

Trying. I need to get my W115 intake in first and to do that I need a replacement turbine for the Holset to know what angle to weld the inlet on.
