Lol Genius, I always forget to ask the obvious. Knowing where it was leaking would definitly help.
And right on ibjags..... Warranty is always important when getting new engine.

I performed the leakage test again. The air is neither going through the intake nor through the exhaust. Also the cooling water vessel shows no signs of bubbles at all. But I cannot identify where the air goes actually. I listened carefully at the oil dipstick tube as well as at the breather nozzle at the right bank but to no avail. The only sound was a hollow noise of the air inside the crankcase. Thats why I removed the valve cover, checked that all 4 valves on cylinder 7 are really in closed position and did the test again with the same results. Finally I did the leakage test at another cylinder at the left bank. It sounded completely different. Instead of this hollow noise the air pressure moved the engine until exhaust valves opened and the air went through them.
So, I am certain that piston rings have to be replaced as recently done on cylinder 3. You made me no hope that I can do it myself without professional help. Because I do not trust Jaguar Cape Town anymore, may be you know a Jaguar expert in Cape Town or nearby with whom I can make this job. What will be the price for a set of new rings in England? Awaiting your advice, many thanks in advance
Ernest

In South Africa there are no many Jaguars. I am quite sure that no engine for replacement will be available. What if I would purchase an engine in England. For what price approx.? In Cape Town the replacement of the engine had cost me Pound 8000,- plus cost for installation (last time, when rings broke at cylinder 3). I relay on your advice. Many thanks.

I agree. You should be able to get a used engine for half of what the repair was done for previously. If you are fairly knowledgable you should be able to do engine swap yourself.

Thanks, Factory JaguarTech and ibjags, so far for your advice. I checked in the Western Cape of South Africa, much to my regret there is no junk yard at all around here, which might have Jaguar parts. So, I have to make the big job and swap piston or rings at least. Please let me know, if you are so kind and tell me where in GB I can get parts or tools to affordable prices. Thank you in advance,
Ernest

If you look at the previous post above this "I did timing chain tensioners myself" you will need those tools that Ken sells.
I was trying to think for you the easiest way to do this job. You will need to remove engine and put it on a rotating stand. On the plus side, it makes it easier to do timing chains etc out of the car and also to get crankshaft bolt out.
You will need to source all the gaskets. ie, cam covers, cylinder heads, intake manifold, throttle body, timing cover, exhaust, bedplate to block, etc.
Once engine is removed, take off the cam covers, intake manifold (including supercharger which you will also need seals for) take off front pulleys etc, remove timing cover, remove the chain tensioners (these shoudld also be replaced while you are in there), remove timing chains.
Remove the cam bearing caps, loosen slowly in rotation so as not to snap camshaft, keep in order as you remove them.
Remove the cylinder heads. The bolts are very tight. Get new head bolts also. Do not reuse the old ones.
Once the head etc is off, rotate the engine on the stand and remove the lower block. Remove only the crank bearing cap you need to get the damaged piston ring out of. When you reinstall, the bearing should be ok as you are using the same parts, only the piston ring should be changed.
Reinstall and you should be good to go.
Email me your email address and I will send you the correct procedure for pulling the engine apart. It is a HUGE undertaking and you will be doing this on your own. All I can say is good luck. I still think your best endevour would be to source a used engine somewhere and get it shipped to you and just replace it.

Hi FactoryJaguarTech
I appreciate the patience you show in writing this particular description for me. Furthermore I am looking forward for the procedure to pull the engine in bits and pieces. But I am quite certain I will succeed as long as I have such good advise. My e-mail-address is lederer@telkomsa.net and ernst@ledcom.cc.
The link you sent shows a company in Johannesburg, which I contacted yesterday by fax, maybe they will quote me a fair price to do the job, then I will not hesitate to place an order to do so.
Many thanks so far
Ernest

please let us know how that place in Johannesburg works out. Always interesting to see how others operate.
I will email you the procedure soon.
I think we all wish you the best of luck.
