“…..Best I can tell the only O rings are the ones needed for the line to block connection? Any suggestions for sourcing these O rings would be appreciated.
SNG Barratt has them.
note: however it has been reported on this forum that the stock size o-rings did NOT seal resulting in a small oil leak. The poster replaced them with a larger size o-ring. However no mention of what size was used or where it was sourced.
note: I replaced two of these aging hoses, which weren’t leaking btw, with genuine Jaguar parts sourced thru Barratt. Imagine my surprise when the new hose started a small leak at the metal / hose crimp point.

From memory, all the o-rings you need (6 count) come if you buy the set of 4 lines. If you buy lines individually, one specific section may not have the o-ring for the middle connection because it comes with the next section. As we have discussed before, these lines see the same pressure, so they should really be replaced as a set.
One day, someone with more time or friends in the industry will identify the ferrule and suitable crimping tool for this job. Then we will be able to fix these from home. Probably just a matter of time before Jaguar runs out of these pre-made lines and leaves us on our own.
It’s been reported here, and elsewhere on other automotive forums, that a decent hydraulic hose repair shop can make a set of oil cooler hoses that can withstand a much higher pressure than than our cars are capable of producing .
So I’m guessing two O rings at the block, two for the intermediate connectors and two on the oil cooler itself? That would be six. Thanks all for all the input I think I will just match up replacement O rings locally when I get them out. Never had a problem doing it that way many times in the past. I’ll let you guys know how I make out again thanks.

PS it’s worth pointing out that 99% of the catastrophic failures with the oil cooler hoses are not with the o-rings.
when the hoses fail it’s almost always at the crimp point where the rubber is attached to the metal fitting. Just replacing o-rings does nothing to protect you in these most common failures. The entire hose must be replaced once it reaches the “aging out” point. Which most sources agree is about 10 years.
Many of the cars still on the road have hoses well over the 10 year old mark, and are living on borrowed time. One of the first things this forum taught me when I was on the prowl for my current XKR, was to make sure the following original items were replaced :
1) Cam chain tensioners
2) oil cooler hoses
3) water pump
Once these known problem areas are addressed, there’s no reason why the XK’s can’t be as reliable as any car from the same era.
I picked up the oil cooler lines today from the hydraulic hoses shop. The work done seems to have been excellent quality. The guy only charged me $130. He deducted $30 from his estimate upon hearing it was a Jag. He said, I’ll see you soon when your power steering hose fails. Little does he know that’a not a problem with an ‘04.
I didn’t get the chance to install the lines today because I was busy with orientation for the residency. I will have to see where I can source those Viton oil-rings you guys spoke about.
I will find a source for those Viton o-rings tomorrow and I will also buy 9 quarts of 5W-30 synthetic and an oil filter. The car is already on jack stands and needs an oil change anyways. I might as well get that done as well.
Tomorrow I will post pictures of the rebuilt lines.
Actually had a problem with that. The O-rings I bought were a tad too large and the hose would just not slide fit, in spite of copious lubrication with oil. I haven't been able to source an exact size o-ring. I might end up having to order the OEM one if I can't find the correct size anywhere else.
I finally got the problem solved yesterday. I was able to locally buy a pair of OEM o-rings (to the block connection) from a parts distributor who just happened to have two of them in stock. I couldn't find my caliper or Boley gauge to measure the o-rings. I decided to just go ahead with the install. The refurbished hoses seem very robust. He used hoses that withstand up to 305 psi of pressure, and the crimp he said is not aluminum but is instead "metal", which is the term used by many people here when talking about steel.
I also did an oil change and started the car. Confirmed that I have no leaks from the hoses and only a small tiny leak from the passenger side valve cover. The engine is also running as smooth as ever. I'm glad there was no damage and that I caught it early.
