300SD falls dead in 3rd gear, with White Smoke
300SD falls dead in 3rd gear, with White Smoke
722.120
Last weekend I was on the way to my friends house to work on my 1979 300SD. As I was pulling on the main road, I give the car some gas to accelerate, I hit about 40 MPH, when the car shifted to 3rd a little abnormal. I didn't think nothing of it, as I continued to cruise at 40 MPH. I stop at a red light right before my turn on to the highway. Once on the highway I know I had a problem, once my car got to 3rd it felt like I loss all my power. I got to 50 MPH (3000 RPM's) very slowly, when I got to 55 MPH the car shifted to 4th (2200 RPM's), but that was my top speed. I downshifted to "S" or slope position, the RPM's jumped to 3000, but I still couldn't accelerate pass 55 MPH. On the way to my friends house I had to cross over a tall drawbridge, once I started to head up hill my speed started to drop, I was only 39 MPH when I got to the top of the bridge. Before this day I had no problems cruising at 75 MPH to 80 MPH on the highway.
Yesterday I had no choice but to drive the car for business. I still had the same problem of the car not wanting to pass 50 MPH, but now I notice have a "lite" white smoke trail once I hit 3rd gear. It took 22 seconds for me to accelerate to 55 MPH. . If I come to a stop I had a little bit of smoke come in the car. As soon I start to drive again, I leave behind a white smoke cloud.
Has this happen to anybody?
Maintenance done to the car in the last two months:
-Oil Change
-Transmission Filter/Fluid Change
-Rear Differential Fluid Change
-Valve Adjustment
-Injector and Injection Pump Purge
-Replaced Both Fuel Filters (twice)
-ALDA Vacuum line cleaning
-Cleaned Fuel Stainer

It was suggested that I change the fuel filters and switched the inlet and outlet fuel hoses, and see if that fixed my problem. However nether worked.

Any coolant consumption? Does the radiator hose get hard soon after starting the engine? Does the oil look like a milkshake?

Sounds to me like a blown headgasket.

Hmm. your the 2nd person that said that. However I don't have milkshake oil. I'll have to check the hardness of the radiator hose and get back to you.
Thanks.
