You are right. I did say both. I was thinking of the car being simpler, but I guess I was also thinking of the fuel system in addition to the newer stuff on a 560sl:
- idle control valve
- crank position sensor and no ability to manually set timing
- lambda feedback loop and frequency valve
Those are all things that the d-jet doesn't have that I think make the car simpler to work on.
Fonzi, I don't mean to be an asshole about this, and if you like D-Jets, that's your business, but if those are the only things you can come up with, your argument really doesn't hold a lot of water. To wit:
-D-Jet also has an idle control valve, it's just not called that, it's called the auxiliary air valve, and plenty of folks have had problems with those, yourself included, as you testified here:
-Why would you need to manually set timing? In any case, I'd much rather a CPS than those lovely trigger points...
-Can't say I've heard of too many lambda-related failures...
As for your friend's 380SL, I don't know what's wrong with it, nor do I care. However, if the people he keeps taking it to can't figure out the K-Jet, I have serious doubts they would get anywhere with a D-Jet either.
Again, if you prefer the D-Jet, that's fine, but you reckon there might be a reason why it disappeared after 1975, while K-Jet lasted another 20 years?
