    Wreck advice

    I have a 2003 D2 that got hit in the passenger side front quarter panel, passenger door and passenger rear quarter panel... some young guy decided he missed his turn, whipped off the side of the road and without looking apparently, gunned it to make a U-turn, thereby slamming into the side of...

    P0130 - replaced o2 sensor - now have P0134

    I had a P0130 on my '03 D2, so I replaced both O2 sensors on the driver side with some cheap Chinese sensors from carparts.com. Before replacing also had misfires on the driver side, P0171 lean code and horrible gas mileage. After replacing, ran good for 150 miles or so, now I have P0134 and...

    Code set

    I have new O2 sensors on the way but was hoping to get you all's opinion. I have the following set of codes: P0130 - O2 Sensor Circuit Malfunction, Bank 1 Sensor 1 P0171 - System too lean, Bank 1 P1300 - I think it's a misfire code of some kind... P0300 - Random multiple misfires detected...

    Vacuum Readings

    I hooked up a vacuum gauge to my motor (4.0) the other day and it indicated around 14 inches of mercury with a slight jitter. I thought it should have been closer to 20 or so, but I'm in Middle Georgia, fairly close to sea level, so is that where you other Rover owners see it? My jitter...

    Recognize this connector?

    I can't seem to remember where this connector goes on my '03 D2... It's located on the passenger side, up in front of the engine, near the radiator.

    Misfire on an engine swap - 4.6 to 4.0

    I just recently swapped in an old '96 D1 4.0 engine into my '03 D2 that had a 4.6. The 4.6 had a crack behind the number 5 cylinder wall, causing pressurization of my cooling system. Other than the overheating caused by the cracked block, the 4.6 ran pretty good with no misfires, vacuum...

    Oil pressure light

    I just installed a 4.0 into a '03 Disco 2 after my 4.6 died. I have a mechanical oil pressure gauge hooked up to a fitting between the block and the oil filter that indicates I have around 50 PSI at idle and it goes up and down with RPM from there. However, my oil pressure light is on most...

    Coolant leaking from bellhousing?

    So after putting my engine back together, it seems to be leaking coolant from a pinhole in at the rear of the bellhousing where it bolts to the transmission. I supposed it may not be a pinhole and coming from somewhere else. But I stuck my finger over the apparent pinhole and the fluid acted...

    '03 D2 Fuel line part search

    I bolted my block back onto my transmission, discovered an issue and pulled the engine back out, stupidly forgetting that I had reconnected the fuel line to the injector assembly... Needless to say, I busted the fuel line connector in half. I don't need the entire "valve assembly purge...

    Bell Housing Bolts

    I transplanted a 4.0 into my '03 4.6 Discovery 2. I ran into an issue lining up the bell housing to engine bolts. Put six bolts through transmission into engine. Left some play. Installed the bolts on the flywheel / flex plate and tightened. Now I can't get the bolts that go through the...

    4.6 / 4.0 swap

    4.6 / 4.0 swap ---SUCCESS---- !! My 2003 Discovery II engine failed some time ago. Looks like a sleeve problem. I also have a 1996 Discovery I, manual transmission. I am in the midst of swapping the 4.0 out of it for a Chevy 350. The 4.0 was running when I pulled it and is just sitting...

    4.0 Carburetor Conversion

    Looking to convert from EFI to a carburetor on my Disco I, 4.0 engine. It has electronic ignition. The plan is to also swap that out to a distributor and coil. My question is this: Electronic ignition is currently working fine. Can the EFI be converted to carburetion while still using...
