I absolutely LOVE the tap on a hose clamp tool idea to clean the threads. It's looking like i'm going to have to do my head gasket on my new to me S3 XJ and will definately be using this tip!
First time I have seen detailed explanation about correct fitting of rods, lifters, and thread cleaning. Very useful. I do hear stories about people's engines expensive head gasket replacement, and then engine leaking oil. Good to know
I welded a tap onto a stud and welded a domed nut on the other end. You can get oversize studs with a shoulder and tap into the block face. Tip> if you can't get to the stud hole in the block to clean out any water to stop hydraulicing, with a hacksaw cut a spiral slot in the thread of the stud so as it screws in the water comes up and out.
Nice work. One tip when using the double nut method is to keep a wrench on the bottom nut with some opposite tension when tightening the top. This ensures that the bottom one cannot loosen and prevents having to tighten them together so much that it deforms the stud thread. Also nice job diagnosing the original failure. Looks like you are taking much more care than the last person did.
That looks like a late Series 3 4.2 litre block. They were a bit more fragile than the earlier blocks. This should also mean you have the Series 3 head with the larger valves. These engines are very interesting. My favourite of the XK engines is the short stud 3.8. Wish you much success with this, I’ve rebuilt a few of these in my own various Jaguar models. I used a good quality copper coat grease whenever I worked with these studs. Works well when pulling the head from the block the next time.
It did have the bigger valves which is nice. I have a shirt stud 3.8 in my 1966 S-type that I will be restoring. I've heard that they are some of the best XK engines
2 months for an engine rebuild isn’t too bad considering you’re not working on it all the time and filming. I’ve never rebuilt an engine and I plan to do it on my xj6 using these videos
im getting one amazing info on the build thankyou and your like a C S I ha tracking the studs down to where they were nice work LONG ONES SHOULD BE YELLOW SO PEOPLE KNOW WITH LONG PRINTED ON EM
@@LivingWithAClassic sounds like you got a great buy on this car. Buying a car with a blown head gasket can mean major repairs to fix (or replace) a badly overheated engine!
I await to be shot down here but your long studs should be opposite each other not next to each other as my original 1969 xj6 series 1 has the engine crane hooks going across the engine, perhaps this is where the confusion came with the last rebuild with the wrong studs being put in the wrong place

Thanks for the great tip! I hope I am and that it will run well

Excellent video and root cause analysis!

Thank you! It does take about 2 to 3 times as long when filming. I'm very glad the videos can help you

hi mate hope you can help me got 1971 4.2 block and a 1985 head will it work because of the water ways?
Excellent and very educational!
Thank you Stig! I hope to be on the road very soon
One would think that on observing the different size nuts that one would number them and photograph them in position prior to dismantling
You use original compressor for replacing a front coil springs. Are you able to send me a dimensions of each part of this tool ?
The nut positions being incorrect would be good knowledge to detect this problem prior to dismantling;could save a lotta work
Are you using bottom tap or a tapered tap?
great video - sounds like you found why the engine failed.
I really think that must be the reason. Nothing else seems wrong or damaged

very interesting !
Thanks for watching 😊
why no anti-seize on those studs?
It was added later. You can see it when I put the head back on
If you have a “Long Stud” XK block corrosion of the studs is very common.
It certainly is. These studs were not very old so thankfully not corroded.
So are you basically thinking the engine was rebuilt incorrectly at some point?
Yes I belive so. The top half was taken apart at a shop when it was owned by a previous owner. My guess is that they didn't put it together correctly

Take off all studs! Take new one! The rust destroyed your gasket. This engine should overhauling - all! This job doesnt work for long time.
