Major XK engine work.

Indeed brother, the location of the air scoop and the part number of the water hose was paramount to the whole project 😂😂
I would have still been here lost😂
Thanks guys for the complements, thank you🤗🤗

I really enjoyed this thread SBS, thank you so much for posting and doing the rebuild in an extremely rapid time -- for many of us this would have been a multi-month project.
In the NE USA a $15,000 budget will give you a nice selection of XKs with 100,000 +/- miles on them. Most are already had 3 owners and incomplete service histories. My expectation of buying one would be to budget for a full suspension rebuild and a motor rebuild like you have done "regardless of what they tell me." With limited support from JLR the task for a DIYer is daunting. This thread, and the encouragement of others who have rebuilt other complex low-production motors, is very encouraging.
My X-Type Wagon is a very rare beast and the parts for a rebuild of it's 3.0l 6 are impossible to source. Forget about rare parts like the rear hatch. The 4wd transfer case blew on my car 18 months ago, $1,900 for a rebuilt part assuming we had a rebuildable core (or pay another $400), 8+ hours of labor to install, basically the value of the car. And if the parts weren't available, that would be it...
I hope XK parts will remain available -- and the timing kit!

Well obviously the scoop was a deal breaker and and without it, valve seats are just a frivolous spend and the entire project a waste of time and money.

1 of those rod bolts is like $14 at the Jag dealer. Compared to $35 for all 12 from the Ford dealer. Same exact part, just need to know how to cross reference =]

I have no doubt that this thread will help many in the future.

No the 4.2L is NOT known for dropping valve seats. In fact that is the ONLY example I have ever seen. The main problem is once the low coolant light comes on you must stop. Regardless how close you are to home. We have post after post where they just keep driving for only a little bit. You can't do that with an all Al. engine. High chance of major engine damage if you do!
Took my 2005 S Type R to 132K before selling it. The 4.2L is one of the best engines Jaguar ever made. Especially compared to the troublesome 4.0L!

Displacements:
The current 5.0 and 5.0 supercharged are world class engines; if cared for will serve admirably. My last X350 had nearly 180k miles on it when it crashed and burned (in that order) It didn't burn oil, and sounded like new. Never required any timing chain work, though I went through two thermostat housings. Biggest weakness, IMO is the continued fascination with plastic parts, excluding the intake which is fine. Plastic water pump impellers and thermostat housing are weak points, and external plumbing is ridiculously designed - too many components = too many failure points. Replace old hoses, pay attention, don't overheat them, don't replace the iridium NGKs with cheaper or non-stock plugs and the engine should serve incredibly well. My current car, NA AJ34 with 109k on the clock still runs 0-60 in 6.1 seconds, same as when new, and gets decent fuel economy for a full size, 300HP luxury car designed 2 decades ago.

Hey so tomorrow I shall be replacing the inlet manifold, water pump , auxiliary belt ect ect and most if not all the connections that I have disconnected are labelled.
I will say that if i am stuck with certain positions of certain connectors, i may ask you to be kind enough to help me if i post a picture of it and tell me what should be at the end of it🤔
I think i have it all labelled and covered but giving you guys a heads up will give me an option 🤗🤗
Bought a few bits of new goodies for her, including thermostat and housing, bought a new water pump two weeks back. Also grabbed a new header tank🤘 Wanted one of them babys for a while🤗
See you guys tomorrow 🤗😎

1. Where did you get this kit
2. What does it cover (thermostat, housing, anything else?
3.should I fit one? My car has done 57000 miles, im thinking preventative maintenance?

Hey, there is no kit. I just bought items separately. Water pump, thermostat housing, thermostat, header tank ect ect. Bought from here along with head gaskets and bolts.

There is no kit apart from the timing chain and guide kit that I bought and fitted once the engine was going together.
The water pump/ thermostat assembly are quite straight forward to fit.

Sorry to hear about the troubles but it sounds like you've come out of the other side of this saga with a running motor.
Not to hijack the thread, but I hear about the valley coolant line going out in these motors. Is that the black hose with two bands on it right in the middle/front of the motor? Did you replace yours? From the picture it doesn't look that bad so I may not fret as much over the prospect of mine going out.

Everything I seem to be reading about the valley pipe is that they eventually crack, I'm replacing mine as preventative maintenance, I think SBS bought all the pipes including this one, though didn't end up changing all of them

I really don't want to pull my car apart to replace it as a preventative measure so soon into ownership. The girl only has 50k on her so far and hoping to get a few more miles under the belt before having to do all this.
Does the pipe fail more on the SC cars since the oil cooler happens to be in the valley too throwing off heat?
#159
Cheers for the link. Reading the X150 service manual wasn't much help in terms of pinpointing the valley pipe. My Porsche Cayenne S had the same problem at 120k, but it was a slow leak thankfully. Porsche actually recalled it and replaced with an alloy pipe.

From what I can tell the best way to drive without risk of sudden and catastrophic failure is replace:
- Water pump
- Thermostat
- Valley Pipe
- Header tank
- Any other pipes that appear soft
Having read the horror stories and seeing how relatively simple it all is to change (bearing in mind my car comes off the road for 6 months from November anyway), I'm going to do it - I'm also extremely bored now that I have fixed the brakes, changed the broken aircon condenser and fixed the Pedestrian Warning mini nightmare I had
This stuff will be a nice way to pass the long dark winter nights.
I don't know if the SC is more prone to it than the NA

Thanks!
SBS,
Thank you for doing a pretty comprehensive write up of your work! It will serve as an inspiration for many of us as time goes on.
Anybody have thoughts about whether mileage or time is more important for hose and/or plastic part replacement? Should we be more concerned with 50k miles or 7-8 years?
