Spin on Oil Adapter

[siii8873]

I have read about orientation problems with these. I aquired an "original oil filter adapter" It has FRAM on it? What is the correct orientation of these. I put it in with the filter pointing toward the bulkhead / down a little. Is this correct? Also is there an adapter for installing a pressure sender and pressure switch to the tap on the filter housing?
I would like to add an oil pressure guage, need to hunt one of them down.

The reason they must be oriented correctly is that many filters have a check valve, or, anti siphon valve. If the adapter were put on backwards and the pressure side then plumbed to the output of the filter, you'd get no oil to the engine. I'm not sure whose adapter you have, but I recall that the Wise Owl one is stamped on the side.

The Wise Owl one has a data plate riveted on that says THIS SIDE UP, or something like that. It also has two threaded ports for senders, etc.

At least mine does.

Mine came in a Land Rover green/white box and has "FRAM" cast into the housing. Was told it was an original NOS adapter.

Interesting. Photo...photo.. pls :)

To use a mechanical oil pressure gauge and an electrical warning light out of the same port I used a T fitting from Holden in the UK http://www.holden.co.uk/displayproducts.asp?sg=2&pgCode=070&sgName=Hardware&pgName=Gauges&agCode=0611&agName=Smiths+Classic+Gauge+Fittings
It worked really well.

That's interesting, But I've never heard of a Series truck with spin-off oil filter, new from the factory, so I wonder if it was sold by Land Rover, after series production stopped.

Maybe so, but since the OP put this in the Series section, that's what truck I thought he was referring to.

Don't think it is that one on the schematic, does not have some of the features. It is on a SIIA 2.25 petrol. I guess just because it's "original" does not mean to a series truck?? I looked at the box it came in and do not see a part number. Hope it's installed correctly.

Spin on filters came standard on the 2.5L engines, In production from 1985 through 1989 (British army used the 2.5L diesel through 1994).

LR part number ETC5347 gets you a new adapter, gasket, oil pressure switch (shown) and a genuine Land Rover spin on oil filter. Or at least that number used to.

Thanks TA, but we were talking Series trucks, not 2.5 engines

Sure but there are at least 5 active members of this board that I know of who DO have Series trucks with 2.5ls. Then there are those 2.25s with 2.5 parts. It has been so long that any of thess trucks rolled off the line that just about any parts combination is possible now. ETC6519 (http://www.johncraddockltd.co.uk/products/etc6519_conversion_filter_spin_on_filter_for_2_25_ engines.php) might not be original to the leafsprung trucks but people have been retrofitting them to 2.25s since the '80s. :thumb-up:

I thought you were talking about spin on filter adapters that fit the 2.25L engine. Sorry if I misunderstood and that only factory Series engine parts are acceptable to this thread.

I assumed a genuine Land Rover part that would be a bolt on solution would be acceptable to this thread.

Constant dynamic tension: and this occurs frequently between purists and practical types (and I note that we occasionally occupy changing turf on that continuum). Still, I welcome TA's input and knowledge, even if it requires clarification and risks bruised feelings and/or egos. Yes, it might justifiably require clarification. But, as a frequent reader of threads and an obsessed series newby (restoring my father's 2a- goal is to drive the vehicle in 2012. It sat since 1979), I appreciate more info (as opposed to less). So with benefit of the clarifications of 2.25 vs 2.5..... this is all cool. Keep it coming, even the misunderstandings and clarifications And with that, Merry Christmas to all.

OK.

A 2.5L (1985 - 1989) is basically a stroked version of the 5 main bearing 2.25L engine (1981 - 1984) found of late Series trucks. Early Series trucks sold in the US with the 2.25L engine had only 3 main bearings (1958 - 1980).

The 2.5L engine looks almost identical to a 2.25L engine and is easily mistaken for one. They are a bolt in swap for one another and many 2.5L engine parts fit the old 3 main bearing engine.

The 2.5L engine's accessories are modernized with such things as a spin on oil filter. It comes with a higher performance cam grind that often finds its way into 2.25L engines at rebuild time. The 2.5 engine also came with a Weber dual venturi downdraft carb. If you buy a new cylinder head for a 2.25L engine these days you get a 2.5L head as the 2.25 head has been discontinued.

2.25L engine (8:1 head) is factory spec'ed 70hp @ 4000 RPM & 120lbft @ 2000 RPM (series III factory specs).

2.5L engine is factory spec'ed at 83 hp @ 4000 RPM & 133 lbft @ 2000 RPM.

A very noticeable difference when driving. A hopped up 2.25L engine can get about as much HP as what the 2.5 puts out stock though probably notably less torque across the curve (the 2.5 has a longer crank). But you can still hop up the 2.5 beyond stock.

Paint a 2.5L engine light green and probably 98% of the Land Rover owners who look at it sitting in an older Series truck would assume it was a 2.25 with aftermarket carb upgrade.

Personally if I stayed with a LR engine I would have gone straight to either a 200 or a 300 tdi, and gotten even more power while using a lot less fuel.
