85 300 CDT no heat

Hi I have a 1985 300 CD turbo and I have no heat. So far I have taken apart the control panel and cleaned all the switches and re soldered any suspect connections, I also fixed the aux water pump so I know that is working now and I bypassed the mono valve so the water will flow through the core, but still have no heat. the fan works and I have air coming out of the defrost and outer vents, but no air at the floor. Can anyone point me in the right direction as to what is wrong with this?

Thanks,
Phil

84 300SD transmission governor screens

I would like to check and clean the governor screens in my 84 300SD transmission, but have no idea how to go about doing it. I think they can be accessed near the filter, but don't know anything about transmissions. Any suggestions? Are there any books or manuals available to teach me how these transmissions work and how they can be serviced and repaired?

Thanks for your help - Steven

84 300TD wagon transmission leak

I have a transmission leak. It seem to mainly be leaking out of the driver side (opposite the drain plug) of the pan...mainly from the center bolt back toward the rear (toward the rear of the car) bolt. It almost looks as if it's leaking out between the pan, the gasket and the seal between the gasket and tranny. I've replace the filter, the gasket and the pan.

Hopefully this wordy description can lead somebody to help me out. Thanks in advance.

82 240d smoking bad (IMO)

I recently did a valve adjustment, hoping that the minor exhaust smoke would go away. It got worse. The engine smokes on startup, smokes really bad and runs rough until it is warm, then smokes enough to be annoying at idle. It appears to be oil smoke. I tested compression, wet and dry, and that was fine (dry-330, 340,340,335). According to previous owner's meticulous records, the engine was overhauled at 515K, am at 565K now. Any insight would be appreciated!!
