I did. Can't remember if I had an issue or not though. I don't think I've got it anymore (but I'll check) as I got the paper version last year.

I have never tried to run RAVE on Android, it runs under Acrobat so it might be possible, others with more up to date knowledge than me may know.
Edit. I have just Googled it and it seems that Android does support the use of Acrobat PDF

Just checked, haven't got it anymore, I remember it caused issues with storage or memory or something on my phone as that's all I have. I'm pretty sure I downloaded it off one of the p38 Facebook groups so have a look under their files.

I think the oil might be black looking which indicates its contaminated.

If you think about it, the oil may well have been in there for 20+ years.

Most likely burnt

I draw the old oil out with a vacuum pump,
Refill, run the engine while steering left to right fully and continue like that until I'm happy with final color after draining and refilling repeatedly.

Just looking at vacuum pumps before your post lol. Looking at youtube tutorials.

How much does the system take?

I just took one of the pipes off the reservoir and let it drain, takes any crud out at the same time.

That's the stuff, not sure how much as I have a 20 litre drum of the stuff and just pumped it in.

Which is the inlet and which is the outlet hose on the steering fluid reservoir?

Steering. The fluid is ATF, same as the gearbox.

+1.

New Dexron 3 in the steering reservoir. You can undo the 2 8 mm studs and turn it upside down. Refill, drive for a week or so and then do again.

I was going to pump out the old oil in the reservoir remove the return line (blocking off the return nozzle on the reservoir) then refill the reservoir with clean fluid & vacuum pump the old stuff through the system while drawing the fresh fluid through and topping the reservoir up as I go but I need to know which is the return hose under the reservoir.

Careful with the vacuum pump, it may do damage. I do not remember which is the return pipe so it's trial and error. Better put the return into a bucket and let the pump do the pumping IMO.

Only if the steering pump is functioning my mate.

Cheers. It's not a electronic pump it's just a manual one. Could that do damage/how would it damage it?

Would I have to jack the front tyres up off the ground or is there another way like putting cardboard under the wheels?

UnitLandy · 2025-08-13T22:04:52+0100

From what I can deduce, the smaller port on the base of the reservoir is the return line.

When I did mine, it oil was sucked out with the engine not running as to not run the risk of cycling the steering pump while dry.
I think this is what our mate Keith is saying.
You can do either way that suits, I.E. A full dismount.
I chose the vacuum way simply as it was the least invasive.
Actually if you do remome the pipes, you get to clean the reservoir properly and replace those bloody pipe clips that need squeezing up every know and again

Lifting the front wheels is a very good idea as it is a bit kinder on the tyres
