[diesel_mercedes] Saturday Repor

 

So ;

My W123 Coupe has been loping worse and worse at hot idle and smoking (excess fuel) again too *:-S worried .

I drove it to the show shine this morning then home where I did a hot valve adjustment, a thing I don't normally like to do but Mercedes says when you're fighting with problems or the Customer is waiting, it's O.K. to do a hot valve adjustment, just open the valve gaps to .006" intake and .016" exhaust .

Driving home it struggled to reach 105 MPH and never really reached full 82*C operating temp but was plenty hot when I popped the hood so onwards .

Several valves were tighter than cold spec., none were zero lash so that's good .

I carefully adjusted them as necessary then changed the secondary, spin on fuel filter ~ it wasn't filthy inside but rubbing the inside of the filter housing with a clean white napkin resulted in lots of super fine dead black stuff .

The added on micronic paper element filter in the fuel return line was a bit dirty but not like it has been every fillup when I normally change it so possibly I'm nearing the end of this bad fuel problem (possibly) .

I changed it just to be safe .

Then I rigged up a gallon jug of silver bottle Power Service Diesel Kleen to work as a traveling Diesel Purge, adjusted the park brake on Tom's '87 W126 300SDL , cleaned up and headed off, my mangled hand killing me but prolly better for the flexation I gave it working .

I ran out of fuel in South Central Los Angeles (oops) coasted off the freeway and onto a small side street where I wasn't worried about getting hit by passing cars and removed the now empty purge jug, carelssly swapping the fuel feed lines feed for return and so after 400 + strokes of the primer pump and two failed attempts to  start the engine, I reversed the feed hoses and added the spare two gallons of fuel I carry in the trunk, pumped the primer 200 MORE times and after a lot of cranking it lit off, belched a large cloud of brownish fuel smoke *just* as the sun was setting .

Whew .

Boy howdy does my hand hurt *:(( crying .

I know everyone is deathly afraid of South Central L.A. and yes, it's a dangerous place but no one bothered me at all .

The car still lopes a bit at hot idle and smokes from over fueling but is noticeably peppier to throttle response and shifts smoother too .

At this point I'm sure I got screwed by the guy in NC who first lied to then outright cheated me, on the 'rebuilt' injectors I recently bought and installed ~ when I test them I'm willing to bet money they'll all pop off at too low a pressure *X( angry .

Oh well, live and learn .

Except of course, I never learn ~ I trust people to do what they say they're going to do .

When I ran out of the purge fuel the newly installed  paper fuel filter was perfectly clean so I'm guessing the remaining crud is in the tank, a job I hate to even think about in my current health state but I may be forced to remove and clean it properly at home if I see more serious crud in the clear paper return filter .

Stay tuned ~ my plan is to run it close to empty Monday when I return to the Doctor's for more pain filled O.T. fun with my hand, then fill the tank (and the trunk spare can !) with PeroPel biomass Diesel .

[diesel_mercedes] Engine Heater

 

They make coolant heaters you insert in the lower radiator hose, they work very well indeed and provide super fast heat too .

Avoid dipstick heaters at all costs and try to remember to always adjust your valves at the end of Summer as they're the # impediment to rapid cold starting .

Hi, I was concerned about the lo temps in MD last week. So the usual was done....newer battery, starter, glowplugs, changed oil to to usual rottella t6. And she fires up with 3 recycles of the glow plugs on first try. Block heater died some years ago, just when I moved to MD....never needed it in SF bay area.

 So what I usually do is plug in one of these electric cooking coils and place it just below the oil plan to heat up the oil. But an easier thing  I do is to take about half a quart of engine oil, in a glass jar (old spaghetti sauce), heat in MW till it is very hot, and pour it into the engine oil crankcase. Dont know how much it helps, but I do this at v cold temps. MD rarely gets below zero.

Looked at all those alternatives to blockheater, eg dipstick heater etc.,but did not care for any of them. No mechanic wants to take on removing the old blockheater.

!984 300sd, 250+++ miles, odo broke then.
Driven up and down both coasts.
Has never given up, and still ultra reliable

That one looks really nice .

I'm not a huge W114 fan, I nearly bought one once, glad I didn't in retrospect .

Even here in car crazy Los Angeles, finding an un thrashed W114 is getting very hard .

[diesel_mercedes] Vintage GMC

 

Those were _very_ stout rigs ! .

the 5 speed Clark tranny would have been a good option for the Chevrolets but never was that I remember .

The 302 is a legendary engine that powered many a race car or hot rod back in the day, hard to find these days .

302 with a  5-spd trans with a electric 2 spd rear end shift. Ran pretty dang good. Really only drove it twice, once to my land and once when I sold it. I also used a 8 volt in my old 6V VW. Max
