W116, BENZ AID - COMMON QUESTIONS AND ANSWERS

poorly running 240D

The guy who posted this video on youtube.com has been trying to fix this car for several weeks. He bought the car recently, could not get it started, so he pulled the head off, found a cracked piston, replaced it along with all piston rings on all other pistons. He claims that the compression is up to 300-350 psi in all cylinders now. The engine runs terrible. The ALDA is turned all the way out. he lives in area with 7500 ft altitude above sea level. It looks like his injection timing or valve timing is way off(timing chain was not replaced, valve adjustment was done.

adjusting wiper blades

Another water related question, sort of. While working on tracking down the water leak mentioned in my previous post, I (again) noticed that my wiper blades are uneven be a couple of inches. Is it possible to adjust them to make them more even or is this simply a matter of an aging car? If so, where can I find instructions to make the adjustment? thx. Also - any tips on which maintenance manual/user manual (besides the manuals for sale here, which I will certainly purchase as they seem to get rave reviews) is the best general manual to purchase for working on my new 85 300td??

water in cabin - 300td

I know many have experienced this before but this is my first 300td and this morning, after a rainy day yesterday (not too heavy), I found water in the passenger cabin towards to firewall and along the door (most likely gathered there because parked on a slightly unlevel street leaning toward the passenger door). Also a bit of dampness in the rear of the wagon near the driver side rear wheel and behind the back seats. I am going to check the drain holes under the hood when I get home, but wondering if anyone can give me a few other options to look at.

A/C Not Working on 1980 300SD After Complete Rebuild/Recharge

Replaced a/c compressor, evacuated and charged a/c, tested for leaks (found none), replaced a/c belt, replaced receiver dryer, replaced expansion valve, flushed a/c lines. I had cool air (not cold - about 60 degrees at vent) for about three days. Now the air is neither cool nor dry. With the a/c switched on at start up, I hear a squeal. Accelerating eliminates squeal and it doesn't return. Belt is tight. Everything seems to be right but, something isn't and I can't figure it out. Can anyone help me diagnose and fix this?

bolt head snapped off transmission pan

As I was tightening the four bolts on my transmission pan after a filter/fluid change one of the heads snapped off. I drilled a pilot hole and tried to use an "easy-out" which immediatly snapped off flush with the bolt. I managed to drill another pilot hole nexty to it and started lightly tapping in another tap. It also immediatly broke off again flush with the bolt. Have I now made it impossible to get that bolt out of the socket? Should I try to redrill a new hole next to it. Someone even suggested superglue!

that noise is embarassing

I'm a proud new owner of a 300D that has excellent maintenance records. I'm going to take a stab at describing it so I can take a stab at fixing it. I remember this old Saab 900 I once had, the freeway driving was terrible like I was going to loose control of the steering or something. That was the ball joints tie rod problem. Since this site is so excellent, I did my research and may be the rubber bushings for the problem?

79 300D won't start after storage! Help!

I just bought a 79 300D with 116,000 miles on it from an older gentleman. The car had been sitting for about 6mo and so I towed it home thinking it needed a battery charge or at the most new glow plugs. Well here is what I have done.... replaced glow plugs replaced glow plug relay charged battery to 100% primed fuel pump (cracked injectors til fuel came out) tried Kent's trick of putting STP/Oil mixture into the injectors ...Still nothing I am only getting a reading of 8 voltz at the glow plug fuse, the car cranks well but just won't fire. I am out of ideas....any thoughts?

300te wagon self leveling rear suspension (hydropneumatic)/ replacing air cell accumulators

I have seen various postings re harsh rear ride on 300 te wagons frequently being caused by bad air cell accumulators, and that replacing both of these (about $100 per side) is likely the solution.
