Hi all,
I've recently acquired a 1988 Land Rover 110 with a 200TDi conversion from a Discovery. It’s very sluggish and struggles on hills. On a flat, I can reach a top speed of around 50 mph, but on any incline, even on the motorway, I have to drop a gear or two.
I noticed a new turbo whistle that hadn’t been there before and discovered that the turbo actuator rod was seized. After freeing the actuator rod, it seems to be opening and closing fine. I checked the pipes with soapy water and found no leaks. Initially, I thought the turbo actuator wasn’t performing correctly, but even forcing the wastegate closed made no difference.
The new whistle noise from the turbo makes me think all of my boost is escaping. It drives like there’s no turbo at all. The turbo whistle is constant. The turbo itself looks fine though—there’s no wobble at all.
I’ve installed a new fuel filter, and the throttle is opening fully. The 200TDi conversion wasn’t done well. When I got it, everything was held together with zip ties. There’s no intercooler, and the intake pipe to the turbo just goes to a K&N type filter in the wing. While I understand this setup would affect power, it shouldn’t be to this extent.
I haven’t tried adjusting the fuel pump yet. I don’t need a race car, and I’m quite happy with a bumbling slow 110, but I don’t want to be slowing down to dangerous speeds every time I hit a hill, which is all the time here in Wales.
The lift pump appears to be working. By which I mean when you depress the lever you get resistance at the last 10mm or so and get a decent squirt of diesel, I assume this is correct.
I’m new to Defenders, so I might ask some stupid questions. I'm Hoping one of you can diagnose my problem and save me a headache.
