79' 300D loud clunking/rattling from rear end on right turns
My 1979 300D started making a very loud and concerning metal on metal rattle about two days ago on my home. I didn't do anything to warrant it either, it just started around a 90 degree right turn at about 15 mph. Now, it makes the sound which comes equally from both sides every time I turn right at greater than 5 mph and progressively gets faster with speed. It is definitely a rotational sound too.

83 300D Air Cleaner Bracket problems
Hello all; Regarding the replacement of the Turbo Diesel Air Cleaner Bracket on my 1983 300D Turbodiesel, how does one remove the lowermost bolt to remove it? I tried a few things, and nothing worked. Special tool? Flexible socket extension perhaps??? ALSO, In messing around with it, I found that the little metal pipe that sticks into the bottom of the air filter housing seems a bit loose now. (think it returns oil to engine???) It definitely has play - moves several inches in fact. Looks like a nightmare to get to. Is some play normal?

A/C problem below 1200RPM - '82 300TDT
I browsed the forum topics, but couldn’t find a way to search them, so please forgive me if this question is redundant.
I just flushed my A/C system with Hecat Flush, replaced all o-rings (assembled with Nylog), replaced the compressor (used new seals), receiver/drier, expansion valve and the short hose that goes between the condenser & receiver/drier. I added the appropriate amount of oil upon assembly, and took it to the shop to have it charged with R12.
The shop said it held vacuum well and that the compressor was working properly. The pressures for the R12 are according to spec.

1979 300D convert to Turbo?
My 1979 300D is still painfully slow and runs a little rough even after the valve adjustment, purge, injector rebuild and fresh oil and fuel filters all the way around. Is it possible to retrofit an entire turbo assembly with the intake and exhaust manifold (like the used one for sale on this site) on this non-turbo 3.0 engine? Isn't it the same block and manifold? I'm sure someone has had this idea before but I can't find it on any blogs.
Thanks

85 300d Injector Nailing
Kent, I am having trouble with one of my five injectors nailing. Could you lend some advice?
History:
I sold my 82 and bought an 85 with less miles. I noticed that it was running a little rough and was smoking pretty bad. I figured that this would probably be cured easily so I brought it in and did some services on it including valve adjustment, diesel purge, cleaned the ALDA lines, and ran some 85 plus in the fuel. It continued to smoke (though not as bad) so I thought next that it was probably the injector tips so I bought the injector tips from you and followed your instructions on how to replace them and clean the injectors. I reinstalled them and no dice, still smoking and it was then that I noticed the nailing (I cannot remember if it was doing this before. It’s possible).
