Few problems with the xj40. help!!

Postby Jagboy » Wed Sep 24, 2014 7:28 am

Hey everyone. Since I am new here, a bit about myself. Im 17 years old, live in Sydney, Australia. Was able to afford an xj40 through working and buying and selling cars on ebay.
History of cars:
1989 Jaguar xj40 sov
1985 toyota ae86 sprinter
1996 golf vr6 colour concept

Current: 1988 Jaguar xj40 sovereign.

So here is my dilemma. The car was pretty mint when I bought it. It's gone into quite a bad state. The hydraulic fluid leaks, power steering leaks, the oil leaks and the lower control arms/front suspension is squeaking reallyy badly. Here are a few pics to show

So this is the hydraulic(?) leak. Its leaking below the brake master cylinder and into the drivers footwell.

This is the oil leak. It doesnt leak too bad. But basically all the way around the head.

This is the power steering leak. It is coming from the lid? Has got me really confused

Image


Has anyone every expereienced these issues in their xj40?

I really do love this car. Hold a great attachment for it but is it time to sell up?


Thanks for all input and thanks for having me!

Hi and welcome to the forum!
The leak into the footwell looks like the master cylinder seals are shot
The engine oil leak is a cam cover gasket and the power steering leak is usually from the pipe attachment on the side
Good luck!!!!!

Been there, done that... It's not an expensive part, and a repair you can easily do yourself!
The seal usually comes as part of a kit, with the two 'half moon' rubbers that fit at the rear, plus 6 grommets for the spark plug holes.

Power steering: I've seen leaks at/around the plastic PS fluid reservoir, often caused by cracked plastic. I'd suggest a known good used item to replace yours. That shouldn't be too expensive, but I can imagine you'll have trouble finding one in Oz.

For leak detection around power steering, it's best to wipe everything clean with a rag. Then drive it a little Check again. It should then be easiest to trace the source of the leak, as it could be from one or more places.
One I often see is the top hose that goes into the ps pump from the tank. Usual nipping up the jubilee clip is enough to stop it.
But I have seen all the pips leak before too, so check them all. Should be obvious once it's wiped clean. How often does the fluid need topping up?

I wipe the reservoir clean and then after a longish drive it just comes back and spills a small bit over the top. I generally refill it once a fortnight or so.

I do recall my grandfather taking his '40 back to Jaguar for a replacement reservoir when that was dripping PAS fluid from around the cap area?
I don't know if they did anything else with it whilst it was there - I was about 12 at the time. I just remember the old reservoir and cap sitting in a plastic bag in the garage for a long time before it was chucked!

i think the PS reservoir on 3.6 cars is shockingly poor quality plastic. just does not feel solid, and the cap is so light and flimsy. no to mention reverse thread on it for no good reason :roll:
i wonder if its feasibly possibly to fit a tank from a later car. they get gradually better quality as the model years progress
