W123, Diesel Engine Repair

Difference between turbo issues, ALDA issues and wastgate

I have a 1985 Turbo federal model...no particulate filter. I bought the turbo rebuild kit and tested the turbo beforehand. It only boosts to 7.5 psi without the installation of the kit (in summeer). I have not rebuilt the turbo yet. The car is extremely slow off the line and in cold weather....I can floor it for three minutes with no increase in RPM. (Some people even cut my block heater cord off because it smoked so much....as if that would stop me!)

leave WVO in loop mode?

I'm in my 3rd year of running WVO trouble free in my 82 240 using your single tank system with boost pump except for a couple of self inflected problems ( dewatering). I up my mix of diesel in the colder months and run 100% diesel in December, January and February turning off the glow plug heater. Last year I left the system in the loop mode with no side effect thinking the loop will aid in minimizing gelling. I'm in to the same cycle this year . Any downside to looping straight diesel in cold weather?

thanks,

Fred

1984 300D injection pump trouble? please advise

I have a 300D with 250k. recently the car wouldn't start or try to fire up at all until you shut the switch and try a second time and it fires right up. this is a recurring problem but it will always fire right up on the second try. The fuel lines have been replaced a few months ago all the way to the tank and there are no fuel leaks anywhere so I figured the lift pump might be loosing its prime and I tried a little experiment. Before starting up in the morning I used the hand primer pump about 10 strokes and she fired right up first try.

82 300D problem installing rear axels ??

Old axel had enough play to remove. Can't get new axel compressed enough to get into wheel hub (can type). Several Internet articles just said to jack up differential housing. This still does not give enough room. Looks like no way to remove hub without removing lower control arm. Any ideas or tricks to this?

Thanks,

Mike

'85 300D heat driver's side cold passenger

Hot air is coming out of the appropriate places on drivers side, but ambient temp air from the passenger side. Buttons on dash change air routing but still temps remain as above. I have the automatic climate control. Both hoses of the monovalve are hot. Any suggestions. Days of internet searching have come up empty. 1985 300 D eurodelivery model 280,000 mi.

Thanks,
