while working on another issue under the hood, i noticed oil dripping from the bottom of my turbo's boost pressure control valve housing. i have determined that the oil is not coming from anywhere else higher on the block. the turbo spools up fine, but the garage floor is getting wet. do i have to rebuild the turbo or is there a simpler fix?
my '82 300D stumbles when starting in hot or cold weather. i replaced the glow plugs and reamed the pre-chambers. they had minimal carbon build-up. i checked engine (1 degree stretch) and IP timing (24 degress BTDC) and they are both ok. compression is 24+ bar across all cylinders with 96k original miles on the clock. injector release pressure is low (1750 psi) and i plan to replace the nozzles and bump the pop pressures to 1950 psi. could the low pop pressures be the root cause for the stumble starts, or is there something else i need to check?
Kent, thanks a lot for all the manuals and advice you've handed out. We now have 3 300d's that run well and were broken or barely ran when we bought them.
Now to the annoying stuff...there's a noise my '85 300d is
making. It wines, especially before it's warmed up all the way, when I'm
going less than about 45mph and loudest at around 35mph sustained speed. It
also will go away entirely if I stomp on the gas and when the car shifts
and the rpm's change which makes me think it has something to do with the
My dash/center IP lights don't work. I already tried replacing the dimmer switch and that didn't help. I replaced the headlight switch when I first got the car so it might have something to do with that since the replacement one was not exactly like the one I replaced. I've also checked all the fuses in the fuse box and replaced the bulbs with ones that were tested. All the warning/turn signal lights work, just not the ones that light up the dash/trans/etc.
