I haven't actually talked to the owner yet because I won't have the money to purchace it until the end of January and because I wanted to get a little history on Max D's before I inquired about it.
Since it is an auction car, I doubt there is any maintenance history. The car is supposed to be in good overall condition considering it's age and mileage. I thought if it was cheap enough I'd pick it up. I love unusual cars. I currently own a 91 VW Jetta 2 door 1.6D with 254k miles. A rare diesel coupe. It runs good, but needs quite a bit of work. I'm debating on putting more money into it, or buying something else.
Learning about the Max D I must admit I'm turned off by the fact it has an EGR system and requires valve adjustments. My VW has neither. All I have to do is fill it with diesel and change the oil and filters.
Hello
I wouldn't worry too much about the valve adjustments. They do need to be checked, but not as frequently as the manual suggests, that would really be a lot of work. Another nice feature, unlike VW solid lifter engines, you don't need shims to do the valve adjustments, there's a slider in the valvetrain that moves in and out based on the amount of gap you need. It is a hassle to have to do them though, but getting in there isn't a big deal.
Another nice thing about the LD28 is the chain driven cam. With VW, as you know, the whole system is driven off that belt, which can break if you're not prompt with the changing. On the LD28 only the IP is driven with a belt, so if it breaks there's no engine damage at all, it just quits running. To be honest the LD28 is one really good engine, cast iron head, which is something you don't see on many other diesels!
I already drive VW diesels, and I'm very much used to the 50mpg of both my 86 Golf and the 97 Jetta. You're not going to get that with the LD28, especially if has the 3 speed auto tranny. You'll do better with the 5 speed or the 1983 with 3 speed OD auto tranny, but you aren't going to get the mpg that you get from the 1.6D VW...so keep that in mind. On the other hand, the VW doesn't have near the torque / power that the LD28 has either. Wish I would have bought a Quantum TD wagon years ago when I found one!
If you're refining your own fuel then it probably doesn't make as big a difference, but if you're like me and buying petro diesel at the pump, the difference between 29pmg (LD28) and 50 (VW 1.6) is pretty significant.
Then again, just try and find a VW diesel of any kind for under $2k right now, it's next to impossible!
If I keep this car, I'll have to replace my 3 speed auto tranny with the OD tranny, purely for mpg. I can't justify running this thing when I get no better than I do now at 29 mpg, that is unless I were to start making my own fuel.
These are good cars, but with the non-OD transmission / gearing they run the motor at too high rpm. With the torque curve of the LD28 it doesn't need to run nearly this hard to pull the car. I'm hoping that the OD trans might solve this problem somewhat.
At the very least you should go check the vehicle condition and hear how it runs. Make a checklist for specific wear items and then see what the car needs. Also, findout what they want for it, because they may want too much.
