    P1451 Code

    Yes, towards the rear passenger door up on inside of the frame. And, it can be a bit of a bear to get out. But, possibly there is a hose that's cracked or something. Check things out before buying another pump set-up.

    P1451 Code

    If you're lucky (sort of...) you may find a broken wire. Otherwise you may need a new pump. On my '04 I found that all the wires near the plug were broken, a simple re=spice was all that was needed. Don't know how such a thing happened, but there you are.

    exhaust leak(s)

    I couldn't reuse the head, it was cut too deep, probably .030 or more. Could have cut both heads to match and jacked up the compression ratio a bit.

    exhaust leak(s)

    My wife's Range Rover LWB blew the head gasket in front of number one cylinder. It blew to the outside, so no exhaust gas in the coolant or any other sign. It did sound like a Sopwith Camel in the end, spitting fire. And it did etch a groove in the cylinder head, a kind of flame cut.

    Radiator replacement.....

    I thought I'd get a nice four row from FleaBay (yes, I know). BIG mistake, not one hole lined up, the base pins were off by an inch and the sensor hole was threaded for 1/4" pipe thread. Not even close, doesn't cover it... The seller would admit no fault (really?). Thanks China (the seller...

    Using a coolant pressure tester with the intake manifold removed

    There are several coolant connections on the intake manifold. Cylinder head coolant crossover, intake air heater block, upper radiator hose. It would be best to have the manifold reinstalled for any meaningful pressure test. If you manage clamp off all the hoses to these areas you will probably...

    Front o2 sensor trouble

    I'm using live data from my Bearmach scanner.

    Front o2 sensor trouble

    I should have said it is a D2, 4.6L. Anything's worth a try, I have a bad feeling it's in the wiring harness or the ECU itself.

    Front o2 sensor trouble

    Having a strange problem with bank A and B upstream O2 sensors. Bank A is at "0" volts, bank B is so erratic I can't get a fix on the voltage. Downstream sensors are both working fine. I changed out both upstream sensors (Denso), bank A had a bad harness plug that I changed out. No change at...

    Pulling Main Bearing caps and Connecting Rod caps to inspect wear...Advice needed

    Never, ever, lube the back of rod and main bearings, The main and rod bearings have little notches to keep them in place. If if you turn the engine over, in the direction of the notches with a wrench, the bearings should slide out. You'll never be able to change the rod bolts without taking the...

    Discovery 1999 4.0 V8i GS (Petrol, Automatic) Technical Issues

    Sounds like you might have an "XYZ" switch problem. It's located on the left side of the transmission, at the end of the shifter cable. Like a neutral safety switch. (You're probably thinking, "What the heck is a neutral safety switch?") If it's not properly aligned or there's a problem with the...

    92 SWB: Front brush bar options

    I had installed a stainless Disco 1 brush bar on my wife's '95 RRC. The only thing different was the bolts were 7/16" instead of 1/2". It did place the upper bar pretty close to the hood. Not sure if the earlier RR's were similar.

    Camshaft wear opinions

    When installing the cam and lifters use a good grade of cam break in lube (it's a special type for cams). Some folks just use grease of some type for the cam and this is a big mistake. The engine should be run at about 2000 rpm for twenty minutes to insure proper break in. Use an oil such as...

    XYZ SWITCH

    There are two adjustments on the XYZ. The cable going to the shifter has a metal end going through the XYZ lever (I hope yours isn't broken off), and a slight adjustment by the mounting slots on the switch itself. Put the shifter in neutral (be sure you're wheels are blocked or off the ground)...

    Blower motor not blowing

    Go ahead and pull the blower fan. I just had such an issue with an '03, mine had a bunch of insulation stuck in the fan (from where?). Not saying that is the problem with yours, but pulling the fan will allow you to check over the fan's operation. After dismembering the glove box it's pretty...
