An old diesel hand here locally ( actually a young biod researcher did as well) advised me to try some Howe's additive in the fuel to help with the "bad prechamber" ( its undiagnosed as of yet).

Now, I'm not a snake oil guy. But since I'd like to drive the car for the summer months before I tear into it again, I tried some MMO. No noticeable improvement. still smoked. Still missed badly once the GP's shut off on a cold start, etc.

So I finally was passing a Flyin' J on a biz trip and stopped in. I bought the darker blend ( not advertised as anti-gel).

HOLY SMOKES! Its liked someone unarsed a bunch of leprichans under the hood and they squared away the PC's! The symptoms are still there, but they are SEVERLY muted. No more "rattle with smoke" effect when accelerating. Cold starts are not as smokey. It doesnt miss as bad cold.

Its just a stop gap until I have time to work on the engine. Right now I'm using it as a daily, which is kind of making me feel like a poor boy..?? Oh well,, money is staying in the bank...!

Oh, and the milage badge from MBZ showed up! Cool!

Anyway, I dont want to start a discussion, but if you have the hard start, rattle on acceleration, possibly PC issue which I read is common with 220K on the enigne, Howe's defintely, unequivically works.

Gave that lil black gal an overdose on the first tank, and now I got her hooked on the stuff!
