Nailing update.
 

In this thread I commented about some intermittent nailing that I was experiencing.

Well this morning it was 40°F in Waterloo, plenty cold enough to have had some nailing going on. However, I'm running about a B-80 level of biodiesel right now. No nailing. Period.

In other news, based on info from another thread and in looking at the way the ALDA/smoke control works, I'm now running the ALDA with the setscrew backed out all the way to the stop...there's no smoke and she pulls from idle like an elecric motor; no specific point where the boost digs in. I'm thinking the next thing is to find some ALDA shims and raise that thing up a notch or two.

I'm in much the same condition. I have cleaned the banjo bolts and the tubing. The boost bypass is bypassed (sin committed by PO; I'll fix it once I see a cloud of black smoke). The ADLA adjustment is CCW to the stop.

At full throttle, from a dead stop, with the engine warm, I see a wisp of black smoke in daylight. Only a wisp. :confused: From all the ADLA threads, I believe that I should be seeing billowing clouds of wasted diesel fuel.

My next step is a boost gauge, to verify that the turbocharger is actually turbocharging. Suggestions would be welcomed.

I should have said that, with this recent adjustment, the car is running better now than it has in almost two years of tinkering. :D :D :D

Last summer I was running my worn out n/a 300D. If I put diesel fuel in it, it would nail most of the time. I started running it on B100 and WVO, and it ran like a sewing machine, quiet and smooth. Of course it was a bear to start, it would burn 1 quart of engine oil a week, and the engine oil would turn into sludge by 3000 miles.

My turbo engine in my 240D is very smooth with no nailing on any fuel. I attribute that to good injectors -- bought at a scrap yard and hand tested by me. The oil consumption rate is much lower, needing about 1 quart a month in spite of the numerous leaks.

I have warm nailing at light throttle between 1000 and 1800 rpm, little throttle and it's gone. Little smoke, good power and 25ish mpg, it can nail for awhile as far as I'm concerned. Any good additive will shut it up, stuff like MMO from the other thread will I imagine as well. It's the measure of the quality of an injector how well it resists nailing on crapy fuel I've always thought.

I don't think I've ever heard my VW's nail, there so damn noisy to start with.
