We have good fabrication skills here, but I have never seen enough consistency in people's wants and vehicles to build bumpers and such for stock. One person commissions a custom step bumper for a Series truck. Then it's one off sliders for a DII. Then something for a DI. I understand we...

Rovertym, Safaarigard, Rockware . . . all those names used to be good but most are fading from the Rover scene, as best I can tell We used to have quite a few suppliers but the Land Rover off-road community has really thinned out, in terms of DIY hard core off roaders. Most of the off-road...

We have built engines with aggressive porting and higher lift roller cams. The problem with those is that you reduce reliability in favor of increased power. What a lot of people overlook is that a Chevy conversion reduces reliability too, because the adaptive components needed to put the motor...

When we started to build engines with flanged liners ten years ago, that put an end to the problem of cooling systems getting pressurized by combustion gas going around the top of the liner and into the cooling system through cracks under the head bolts. We weld up the cracks per my articles...

I agree with Roverover . . . take the motor apart and you will find bearing problems. The 03 engines were made "worn out" because the tooling was shot. Many had excessive bearing clearances from new, and when they got old . . .

Good luck!

Are these temps you measure from a consistent spot with a tool, or indicated temps on the dashboard gauge? Be sure you measure in the same way, and if you are relying on the dash gauge, the problem may be voltage stabilization in the dash

If you want to run the system as an air compressor the expansion valve should be removed and an air filter/oiler setup fitted in its place.

We stock heads for quick turnaround in the shop, but the story you tell of crud in the motor isn't going to be resolved by slapping some heads on. That is in invitation to disaster - if an oil gallery plugs you will destroy the engine. The motor should come out and be tank cleaned to remove...

I'm not sure what you mean by that statement. No car is made with a 145psi safety valve because summertime pressures can exceed 300PSI. The typical safety valve opens at 400psi or more, and it's located on the compressor. There is no other common location for auto AC safety valves. The usual...

On those vehicles I recommend the factory fluids. There is no benefit to taking a chance on a fluid that might not be compatible. The factory fluids don't have any performance problems I know of, so there is no functional reason I know to change away from them.

Whenever you have multiple cooling system failures you have to ask if excess pressure is the cause. If so, the usual reason is cracks in the block behind the cylinder liners. I've written a number of articles on Land Rover block and liner failure. Obviously we are just speculating based on...

First of all, most of your insurance bill is for liability and other things that are independent of your car's cash value. Now, when it comes to the cost for collision and comprehensive coverage, the company does not use a straight multiplier of cash value x xxx equals your rate. They classify...

There are two possibilities for coolant use. The coolant is leaking out of the engine, in which case you should be able to see it, especially with a cold engine pressure test. That is most likely. Remember that many leaks don't drip as they just blow away in the wind but you can still see the...

It's been my experience that the forward mounting location of the air suspension shocks puts more stress on the shocks bodies. When the vehicles are run hard on rough roads we saw quite a few Bilsteins snap off. They warranted them, but we learned that Bilsteins did not do well in the forward...

We have a bunch of these old wheels at Robison Service. While they will charge you $100 or more a wheel if you call to buy one at a yard, if you put them on ebay and actually want them to sell they probably need to be $10-20-30 a wheel to attract interest. There are thousands of wheel sets...

Gears get an almost microscopic curve in the teeth when they wear, and those worn teeth will ruin your new chain far before its time. Change the gears when you change the chain. Same thing we learned motorcycling in the 70s.

Bigchief, the difference with your Ford is that it was an occasional 4wd vehicle, so the rear end was made to take the full power in 2wd. That's not the case with a Rover

The only cautionary note I would offer is that the natural 4WD configuration divides the power roughly evenly between front and back. So your 150 horsepower is split, 75 to each axle. Assuming you drive the same way you did before, driving with one driveshaft is going to double the torque load...

The engine management system sets the timing based on reference signals from the cam and crank sensors.
