    Default 4.3L Diesel

    Who has one and lets hear about them, both good and bad... I have owned a few A-bodies but none with the diesel.

    mine had 90k on it the onyl restion why i rebuild it was it had been over heated to the point that on of the piston melted and the ring lost tenstion. if that had not been the case the motor would have been good to 200k plus

    this piston would have brocken in two or more piece with in 5k less if i drove it hard

    the 4.3lt are decent motors, that dont have any problems of the 5.7's (which are fxed with a DX block and head studs)

    i fell that decnt power to make the rather driveable (these vid were taken befor the rebuild) the white smoke it blow by and super low compression causeing white smoke due to unburned diesel. a few notes i have a 3.65 ratio rear but the over all ratios from 2nd to 4th are the same a the 3 speed with 2.84's. well just a touch lower but not really

    Good stuff, I was reading your build over the last couple of days. About a year ago I had passed on an '83 Olds with one and bought a 1990 Crown Vic instead (I do not regret buying it). Now that I have the Century it would be nice to eventually pull the 3100 and stuff a 4.3L in it so all this info really helps. Finding one of these cars is gonna be a b*tch though.

    Is the wiring harness and all that good in the car you have? It may be just as easy to pick up a '94 or so Century and just clean it up, plumb new fuel lines etc. Then just swap in the dash and wiring harness from you '82. Most of the parts across the entire line seem to be pretty easily swapped so it might be an easy way to get a nice car to go with the diesel.

    What kind of mileage can you get with one of those....driven nicely. I've heard exagerated stores on the big 98 5.7 diesels. Can you break 30 mpg with a 4.3? Does the A/C add any drag, or does the diesel just shrug it off?

    You should be able to see 30s or up to 40mpg from what I hear, if you have a heavy foot then obviously less. It all depends on how you drive it. AC Should be a non issue, I really don't see much difference on any engine of reasonable size with or without a/c. Without owning one obviously this is just going with what I have heard though.

    i heard a few (you will have to ask oldstrubodiesel he drives hos more but i heard mid to high 30's it normal. im looking to push mine into the 40's.
    though out my life I haven't noticed any ac system not on a under powered 4 banger that really effectied fuel eco.......the on i can think of that did was my friend (very well running 4wd tercel and it acted as a break below 3 grand)
