I'm getting fluid from from around the windshield assuming that it's coming from the top latch. Waiting for warmer weather before attempting to fix. I could continue to use the car after putting the top down. Could you please advise me how difficult it will be the replace the hose? I know that I can get the parts from Gus. It seems that all I would need to do is remove the plastic cover from the top of the windshield, attach the new hose to the old and pull it through but i'm no mechanic and if it's possible to screw it up I will. Thanks foe any advice.

 

Knowing that it'll hapen to me sometime I've been watching threads carefully. Seems to be an all day job, pretty much have to pull out most of the interior.

There is a guy,name noted in past posts, who will fly out and fix it for a flat fee, $1200. Or so as i recall.

More knowledgable folks will surely respond, wanted to chime in as you are in the middle of a big headache right now.

Afterthought, check to see which hoses the flat fee guy uses. May not be the premium choice $400 hoses that the forum prefers. Im sure whatever he uses is more than adequate.

 

It seems that I was overly optimistic and am feeling a little sick to my stomach right now. If the problem is at the latch is there a repair to the hose that could be done? I have installed the pressure relief valve if that makes any difference.

 

Repairs to the hose do not work. Jaguar had a kit for a while and it was discontinued because it would fail again.

Consider the manual latch conversion until you are ready to do the complete repair:
See XK8 Convertible Top, Manual Latch Conversion and

 

Converting to manual seems to be my best option. Thanks WhiteXKR.

 

This might help you to identify the problem.

I replaced my hoses and top latch and found it extensive but easy. Do not repair the hoses, replace with stainless. Rebuild the top latch at the same time, trust me on this.

A LOT of the interior will need to come out. Delicate plastic parts, too. There's nothing hard about this, it is all labor... I took my time and did it over a weekend.

Add WhiteXKR's excellent remote kit and you've got a modern, reliable system.

 

This might me a new data point . . . .

When was the pressure relief valve installed (miles/time ago)?

Were there any signs of hose failure prior to pressure valve installation?

Can you determine if the leak is from the hose or the operating latch?

Any other info on operation or failure?

 

The valve was purchased April 15, 2015

 

Do you have a large leak or just a drop every now and then. It might be the seal on the hydraulic cylinder. You can put the top down and remove the top cover plate very easy and inspect to see exactly what the issue is. 4 screws, one on each end under the rubber and two in the middle.

If it' the cylinder it can be repaired by Top Hydralics for $150.

 

I have been fighting with myself on how to respond to this thread so here it is.

The LSI valve was designed to reduce the hydraulic pressure to the roof operating system from 1635+-/- psi to 947+/-psi. The reduction of this pressure puts the existing hoses within a tolerance that the hoses and rams can except and still have the roof operate properly. However, the LSI valve will only extend the life of an already stressed system as I have stated many times before.

As for hose or ram seal failures with the LSI pressure reduction valve installed I can only recall 2 (this one makes 3) hoses and 1 ram at the latch and 1 ram at the lift.

I blame Jaguar / Power Packers and the designers of the car for the mismatch between the pump and associated equipment.

I should mention that Jaguar is not the only car to have a problem with the hydraulic system it is only jaguar that has the LSI valve.
