Oil pump covers - Range Rover pump cover on P6?

[Quagmire]

Chaps,

Is there any reason that I can't remove the P6 oil pump cover from my 3500s and replace it with one from a Range Rover? This would rationalise the fleet for me and mean that I only have to keep one type of filter in stock instead of two.

Thanks!

I can't see why not.

 

[Quagmire]

Excellent, I was hoping that would be the answer! I'll give it a go, thanks.

Hi, You do of course know they have a choice of filter threads the same as the cars?

is it just the pump cover or the whole timing cover?

the timing cover may have the fuel pump blanked off.

It's just the pump cover. Range Rover timing cover is totally different, the petrol pump access is blanked as you say, but the water pump footprint is different and sits a lot higher on the cover.

Yep - I have been ordering early Range Rover filters for the P6 from my normal online LR suppliers since i got the vehicle (part RTC3186), but would rather change to the later thread the same as on my V8 powered 90.(Part ERR3340).

Then i can buy the same nice Mahle filters for both vehicles at £3 a go, instead of paying £4 something for a Britpart one...

Hi, Good, The later 3/4" thread is fitted to a lot more different engines and so is a lot more widely available and cheaper. You may even get a deal on a pack of 10 from a factors.

Just need to make sure the filter doesn't foul the cross member?

 

[Quagmire]

That's a good point - the ERR3340's are short like the normal P6 filter, however there are longer ones available much like the 101 filters. These ones are about half as long again so could give trouble.

I used to use these longer ones on the 90 and although I cant remember the LR part number I seem to recall that they were made by Fram and were PH8A filters.

Any of the Range Rover oil pump front covers up until the introduction of the crankshaft driven oil pump will work in place of the P6B item. There are two differences, the former have a smaller diameter spigot in 3/4" as opposed to 13/16" , and the oil pressure bypass valve was deleted. On the later covers, the bypass valve is located within the oil filter.

That presents no problem, provided that the oil filters that you purchase have bypass valves within. The visual way to identify is when looking into the filter, you will see a coil spring at the base.
