2001 discovery ll can someone tell me what engine did landrover use

 

4.0 Liter BOSCH


Use search next time for such a basic question.

 

4 liter later a 4.6 liter was introduced (different piston rods). The RAVE is the factory workshop manual, free download below. Engine is aluminum block and heads, and cylinder liners.

 

thanks, i heard from some of the Land Rover shops in Houston, Tx that the original engine came from Buick. Can you shine any lite on this statement.

Thanks

 

Yep. It's an old block from the 60's.

 

Is the buick block still being used for the 2001 D-2

 

Buick has never "made" the engine for them. It simply sold them the rights to produce the block, and they have variants of it in the D1 and D2. The 4.6 liter has same bore, but longer stroke as an example. The 3950 cc engines have been called 3.9 and 4.0. There are internal variations, like seconday air injection. Sensors and ECUs vary by model year in some cases. Earlier engines allow the sleeve to slip and travel down into the engine. Later models cast a ridge to prevent drop, but the sleeve can move up and tap on the head gasket.

There is no "best year" or "best engine" as the previous owner's decisions about maintenance and fluids and operating temp make a lot more difference. If you get one that Joe Yuppy Tightwad, who got downsized, adjustable mortgage bumped up higher than a farm jack, SWMBO dropped job, and is at home with new kid(s), things like fluid changes maybe got behind.

Here's and engine with 190K and Castrol and Rotella oil changed at logical intervals And one that wasn't. Driving around at higher that reasonable temperatures for long intervals is also bad, and the heat gauges don't show true readings, they are built to point at 50% until past 240 usually.

So buying a used one is something that should be done with careful inspection, attention to codes, real temperatures after 20 minute drive, etc. The units in certain range of VIN number could suffer from an oil pump alignment problems, these all blew up by 50,000 miles.

 

Thanks for the reply.
