Help me out here, if the stock relief valve setting is 8-11 psi, and your hot idle reading ( lowest reading) is say 14 psi, aren't you bypassing the filter all the time?

 

gsxranger - take a read here you are not following how that valve works Oil relief valve

 

Accumulator, T fitting, electric solenoid valve
Hi all, read the whole thread and I am convinced that pre-oiling and frequent oil/filter changes are the answer to many of the Land Rover's engine woes. I think my 2007 LR3 SE with the Ford 4.0 V6 is infamous for timing chain issues but when I replaced it I installed a Moroso accumulator with electric solenoid valve (timed) to prelubricate the engine for 5 seconds when you turn the key to position 2.You see the oil pressure light go out, wait 5 seconds then start the engine, the timer keeps the solenoid valve open for about 50 seconds so the engine pumps oil back into the accumulator after engine start and then closes the solenoid valve, storing about 1 quart of oil at about 55psi and ready for the next engine start, when the process is repeated. The previous owner of my LR3 (250,000 Km) had followed Land Rover's 12,000 Km oil change recommendation and suffered a blown engine, which when we took it apart was very dirty inside. I change oil every 5,000 Km (about 3,000 miles) and use a Ford Motorcraft filter and Castrol synthetic 5W-30, but also have installed the Moroso ever since dropping in the used Ford Ranger 4.0 V6. I expect that the maintenance/accumulator combination will cause the engine to last for many years of trouble free operation. I installed a "T" at the engine oil pressure sender tap on the block and put the sender on one side and the Moroso connected via AN6 hose to the other side. Is this THE answer? Maybe not, but it definitely works, the engine is never, ever, ever dry started, at oil change time just floor the accelerator pedal to crank up and charge the accumulator, then start normally. Or you could just start it normally, one sort of near dry start every 3,000 miles probably isn't significant...

This is a great thread, thanks for sharing...

 

I wonder if the bad advice is on purpose to keep the dealer service center busy after the warranty expires. I mean they give such choss advise. Like flush your coolant after 10 years. Or replace your transmission filter at 50,000 KM then never again .. and no new trans fluid never needed.

I followed this chonkers advise on my Discovery 2 ... now having transmission problems.

 

Well, I'm doing what I think is right, although I've upped the oil change interval to every 7500 Km, still using 5W-30 synthetic and Ford oil filters, I suppose whatever one is comfortable with is the right path, fluids do eventually break down/become contaminated so they do need to be renewed periodically. The intervals are the questionable bit...
