Jaguar 4.2 XK engine strip down (Part 1) - What went wrong?

[@Wilfred-Oldtimer]

Hi Adam, Interesting video. I also stripped my early S3 XK 4.2 engine which had some cracks between bores. A company put in new liners and skimmed the block and cylinder head for me. They also did the reassembly of the crank shaft, new bearings and pistons with new springs. From there I took over and rebuild the entire engine with new chains, oil pump, stuts etc and it’s running for almost 8000 km now . It’s just a lovely engine 🙂 Cheers, Wilfred

Hi Adam, long shot I know....I bought an 83 xj6 s3,..... Just wanted the body, was gunna Frankenstein it, but after driving found the engine, welll....not that bad......do you know much about them?, I'm looking to strip it and rebuild as a possibility as I just got the stink eye from my wife when I told her I was buying a 1uz.....

Hi Adam it might be cool to put the big valve on your 3.8 s type if you are rebuilding its engine. Probably a lot of port matching, tacho drive and water path issues though😊

Too bad the captions were missing from this; the commentary was rather quiet. Would it have been possible to leave the lifting tabs bolted to the head and pulled it off with the engine crane, or was there a good reason not to do it that way?

[@LivingWithAClassic]

You can’t leave them on since the are held on with the same nuts that hold the cylinder head on.

[@gvamedia]

That is one reason and the other is if you try to lift off the head with a crane you will have no success as it will stick very well to the bolts as it will generate lots of friction when only slightly tilted. I could still lift the whole car pulling the head with a crane when it was 10cm above the block. Pushing it with hydraulic jacks and a couple wooden blocks worked fine for me..

[@parrotraiser6541]

@@LivingWithAClassic That certainly constitutes a good reason.

Excellent video can't wait for the v12

[@willguitar7]

Adam, if you haven’t already tried this, stuff some rags in the cam sprocket area of the head before removing the hardware. This should catch what you may drop. You may need to remove/reposition the rags before/after rotating the engine as you proceed. Note: I work on these engines.

[@LivingWithAClassic]

I usually have rags there when it’s an engine I’m using again. This one is just being stripped for parts. I work on them too

[@rob_1359]

Great video. I love the longevity of the engine, great engineering 🇬🇧

[@mikedx2706]

The bottle jack trick for removing a stuck cylinder head is absolutely stunning. What a genius idea.

[@LivingWithAClassic]

Glad you liked it!

[@uhn100]

Hi Adam very good to see you disassemble the engine I think your right it can be skimmed I look forward to seeing the next part thanks Andy Allen.

[@mikedx2706]

Why do the engine's core/freeze plugs always seem to weep/leak coolant over time on Jaguar XK engines? Is it just a poor design?

[@LivingWithAClassic]

Not sure to be honest. When I have had leaking ones they have been rusted

[@rodrigoantunes8502]

maybe a cracked line...

[@jabirucru6970]

As you struggled to lift tat head off I felt my back go!! I would have lifted it a couple of inches with the jacks then wrapped a rope round it and used your engine hoist to lift it off. Saves the back for your old age. Very interesting video.

[@mikedx2706]

Can't wait to see Part 2 when you disassemble the block and crankshaft and front timing cover.

[@jeffharrison5265]

Great video Adam. I think you're onto something there. It looks to me it blew at those areas, but my expertise only matches yours. I agree a skim and new liners and the block should be good as new. I look forward to the rebuilding video someday. Cheers.

[@WilliamKennedy-e5j]

On your advice and watching your videos I had purchased the swivel head wrenches months ago . They are very handy .

[@brendondolan6488]

Very interesting as I have done our xj6 s3 head as it had blown I had watched one of your earlier episodes and it is going to be interesting to see how you get the front cover off etc

[@johndavey72]

Hi Adam. As always great content . Thankyou .

[@charliecoco2115]

Those valve covers are a work of art, must be able to repair the cracks from the inside?

[@rogerpritchard]

Interesting. I'm thinking new liners?

[@ScaphanNetwork]

Would LOVE to see a v12 HE version of this. Great channel. ❤

[@LivingWithAClassic]

Thanks! Some day

[@per-akesjoqvist3593]

Hej, were and how did you learn so much about Jag engines , impressive I must say.

[@LivingWithAClassic]

A lot of learning by doing and research

[@jonpag43]

Hi did you change the studs when you rebuilt it , they are one time use only as they are designed to stretch.

[@LivingWithAClassic]

They were new. Now they are going in a pile for something. Seems a shame to throw them out. Could be used to build something

[@russellwhite7407]

👍🇦🇺

[@tjmthejagmandownunder]

So glad you dropped that oil plug! lol

[@LivingWithAClassic]

We all do it 😂

[@bernhardlist9359]

How did you get the studs out. I did the V12 and had good tools but it was scary to ruin something or brake one off.

[@LivingWithAClassic]

Just vicegrips

[@bernhardlist9359]

@@LivingWithAClassic Wow, I thought being so long and probably corroded in they would be impossible to get out. I have studremover that I could slide over them to get es close to the deck as possible because they where „springing“. Eventually I got them all out without any damage. I felt that I was under more tension than the studs. 😅

[@alexandrecouture2462]

Adam, have you seen the video of a Jag V12 disassembly on the Humble Mechanic YT channel? Interesting to see how it is built.

[@ScaphanNetwork]

Really? He’s a VW/Audi guy? Did he do a Jag V12??

[@LivingWithAClassic]

Yes I saw it

[@alexandrecouture2462]

@@ScaphanNetwork This is what I have written... :)

[@ScaphanNetwork]

Yes sorry. Just saw. Interesting. Although broke my heart to see all those spares go for “recycling”!

[@johnmoruzzi7236]

Clear evidence that Stop Leak is not a good idea ! I think you had pretty much decided previously that you had a bad block with a leak / crack, and that had caused persistent problems. If you can fettle it a bit and save it that would be great, but as you say take expert advice !

[@LivingWithAClassic]

Yes! It was good to try it to be able to see what it does. I will save the block and maybe rebuild it someday in the future. I’m saving a few 4.2 engines for the future.

[@stephentempleton9208]

Nice episode- I like the bottle jack trick!
