    Exhaust Smoke going Downhill

    Like others have said, its probably your timing, probably caused by a bad pump. Try the cleaning, if it still smokes, take a screwdriver and try pushing the advance piston on the drivers side of the injection pump while at idle. That should make it run like crap. If you notice no change, then...

    300SDL: -10F start today, no block heater

    Mine does the faster smoother starter thing too. I have always guessed its because the rings are shrunk and the compression is lowered. Mine spins over fine, but never even tries to light off below zero.

    Centrifuge

    Yes, Its been sitting on the shelf for a few years and may need some cleaning. PM me an address and I will take a look at it and make sure its usable and get a shipping quote.

    300SDL: -10F start today, no block heater

    I certainly don't have a benz that will do that. It was -1 this morning (i am at inlaws in upstate new york) and the benz fired up great after three hours with the block heater. It has over 400K on it so once you get into the single digits it just spins and spins without even trying to fire...

    I buy lots of benz stuff from those guys.

    I like seeing benz traffic here. I am definitely a fan and always have a few laying around. Too bad you don't have a 5 speed to throw in. I have driven a manual 190, they are great little cars.

    Little Trick for Fan Removal

    I can relate. I pulled the collector pipes off of my parts truck last month. I was thinking that the engine would go on the stand shortly for a rebuild, but when I dropped the exhaust I got soaked with water. Apparently the cowl seal is worse than it looked and the exhaust was full of rainwater.

    A lot of centrifuge crud

    If I remember right, the one in the pic came off some sort of Mitsubishi. It doesn't really matter. Its easier if you grab a pump that was originally paired with an external tank. Then the return can be straight piped in. What he did in the pic (which he copied from me) is to use a pump that...

    A lot of centrifuge crud

    This is not my setup, but it was put together the same way by a friend of mine. Power steering pump run off electric motor sending pressure to top mounted fuge.

    A lot of centrifuge crud

    I have a 55gph centrifuge on a 55 gallon barrel. I generally let it run 10 hours per session.. My check used to be to clean out the fuge after 10 hours and run it for a few more, but I don't do that anymore. After 10 hours its about as clean as its going to get. As Leswhitt noted, a single...

    Very bad driveshaft center support carrier bearing

    And now for the rednecker solution.... Unbolt it, move it out of the way and wrap the bearing with electrical tape till it fits tight in whats left of the rubber. Then fix it when you get home.

    Works great. You will need to turn the max pressure way up when you get it. I have a clear line running off it back to the tank so I can see when it is bypassing. That is how I figured out the gasket went bad in it last year.

    Injector pics running wmo

    I have found with my benzes and my John Deere that there can be too much RUG in the mix after about 20%. On several occasions working them hard in hot weather I have had them basically vapor lock. They lose power and die. Once they cool they go back to running fine, or if you dilute the rug in...

    Why are you tucking the engine and transmission so far back?

    A lot of centrifuge crud

    looks just like this one, link. I don't remember where I got it however. Insert flathead in end to adjust pressure. It failed about a year ago and I found that the whole thing comes apart and there is a replaceable washer inside.

    A lot of centrifuge crud

    I have a pressure relief valve teed in just before the pressure gauge. I usually have it set to bypass at 130 and at that pressure it dumps back into the barrel. My routine is to get the system up to pressure when I am in the shop, let it run for an hour or so, then leave it overnight. I would...

    A lot of centrifuge crud

    To keep running the centrifuge, or keep running the oil in your truck? I occasionally get that kind of buildup in my fuge after leaving it on all night. I think its still filtering at that point. I did check the fuge one morning and found that it had built up so much sludge the drive jets...

    Brick nose speedo

    When I have bouncy needles I always clean the whole cable well and then use white lithium grease. As someone else posted, they make a graphite oil specifically for the job, but I have never used it.

    Brick nose speedo

    That is intermittent drag on the cable. Try taking it out, clean, lube and reinstall.

    Brick nose speedo

    Sounds like the cable to me. I have never seen a bouncy speedometer that was anything else.

    Uugghh now what

    As others have said, you have a stuck hub. Take them apart and clean and grease. The only thing that unlocks them is a fairly weak spring in the hub. If you have had moisture in them they can stay locked. They are pretty straightforward once you get into them and you don't even need to jack up...

    Burning oil only on the highway

    How much blow by does it have? Loosen the oil cap at idle. Does it sit there or does it blow off from the back pressure? My experience is that worn engines burn more oil on highway than around town.
