300ce engine loses power at highway speeds

Sir: I have a 1988 300CE with 108k miles. Recently, while driving at highway speeds, 60+ mph, the engine seems to lose power and the red "check engine" light blinks on for a few seconds. It feels like I am losing power in one or two cylinders for 5 to 10 seconds. Then, the power resumes, the engine light goes out and everything is OK. This problem will only occur about once in 20 or 30 minutes of highway driving. I took it to my local mechanic, he drove the car and, of course, this problem did not occur. Any suggestions? Thank you, tjw tward@hseinc.biz

No oil filter?!

Hi I'm a new MB owner of a 1974 240D automatic. Like all vehicle I buy I change the filters as soon as possible after purchase. I believe the oil filter canister would be behind the injecter pump on the driver side of the motor, but alas no oil canister. The previous owner told me that he had put in a newer used motor after the first one blew. It runs like a top and doesn't have any problems but can anyone tell me where the filter is located. ! Thank you for your advice and help. Troubled MB owner.

hard start, air in lines?

Hello, I have a 1985 Mercedes 300tdt which I have converted with an Elsbett system for wvo. It has been great for 2 years. I now have a starting problem, which might be totally unrelated, I think it is an air leak in the fuel lines. It takes two to start the car, one to turn the key and pound the petal and another to prime the pump. In colder weather it is more difficult. i suspect a gasket or seal, i just am wondering how to isolate the problem. Is this a common diesel thing or unique to veggie conversions?

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.
