82 240D will not start when warm

I have an 82 240D with >217,000 mi. This summer it started not wanting to start once it reached operating temperature. It seems like it is getting air in the lines, but if you let it cool down then it will start again. I replaced the flex fuel line from the tank and the one under the hood on the suction side. I then bought why my diesel will not start, lots of info, nothing specific to hot starting problems. I have since put in a used tubo starter and a new timing chain. The engine turns over faster and has more pep but still refuses to start when warm.

Fuel Filter Replacemnent and other Difficulties- Be Prepared!

When my '82 300DT lost power on the freeway I managed to nurse it to my destination and got out my fuel spare filters. I installed a new prefilter and main filter, bypassed the FM10 water separator, pumped on the hand pump, and then found that the lack of a 17mm end wrench made bleeding the lines at the injectors real difficult as all I had was an adjustable wrench. Too bulky for that job. Then I screwed up by not reading Kent's instructions carefully and ran my battery down before the fuel lines were bled enough to get the engine going.

Overheated rear brakes

I drove 15 mi to work, via high way, with e brake partially on. When I got there, the wheel was smoking. I pour gallons of water on them and let it cool down and drove again for about 10 mi. Now I found the brake didn't seems to returned after it's applied, the rear wheels would be almost fully locked after no more than 10 times of braking. The more the brake is applied, the the shallower the pedal gets. So I towed the car back home. What could the heat do to have caused my rear brake to stuck whenever it's applied?

turbo oil line gasket and air cleaner bracket

I recently replaced my air cleaner bracket which required disconnecting and reconnecting the oil line from the top of the turbo. After reassembling everything, the turbocharger leaked oil. There's a paper gasket where the oil line meets the turbo, and I didn't know I'd have to replace it if I ever disconnect the oil line. I got a new one from a local M-B dealer, partnumber A 603 187 05 80, but it's the wrong size. I tried to use the gasket anyway by making cuts in the gasket, but I doubt it is sealed well or will last very long.

timing gear breaks on 420 sel

Hi I am brand new to the forum. My name is Lewis in Nor Cal, I have owned a 1990 420 sel for 3400 miles now. IT has 200120 miles on it, 1 owner and is in perfect shape. Just did new rotors all around belts and oil change. I went to start it on 09/15 and I heard a big bang. opened the hood and found something had made a 2/3" hole in the drivers side vale cover right on top of the timming chain. the motor did not start during this time and has not since. I am going to do a compression check to see if any valves hit pistons etc.
