Hi Guy's.

Got about 1/2 mile from the entrance to Capethorne Hall (classic car show nr Macclesfield) on Sunday when I got a whiff of hot water. Sure enough temp had gone well up to the top and lost all the water. I couldn't get under the front to see where it was coming from due to the car being about 8" from the floor and head is much bigger than that.

I could not see anything looking down from the top but estimated the water was coming from the bottom of the water pump.

AA to the rescue after 3hr wait in scorching sun and took back home. Problem turned out not to be as serious as I first thought, bottom hose from pump to rad had burst so I replaced it, I filled and bled water system, started her up and kept close eye and ear on everything which seemed to be ok. I decided to give her a wash down and went to the rear of the car and noticed very faint blue smoke from the right bank, (car was still on tick over) I blipped the throttle and there was a couple of backfire's from that bank but not loud ones, more like a couple of a hicup's.

I called my friend who does the main work on the car and took it up to him (with caution) this morning. When I started it, it started first time as norm, condensation out of both banks until it warmed up, left it on tick over and watched the exust's, nothing, it was completly clean, no hint of smoke and no backfire.

So took it to my man so he could have a look. Result was he give it a clean bill of health and told me to take it on a short run with some hill climbs thrown in and see what or if there was anything amiss when using it normally, which I did. The car performed just as normal so gave him a call to say that all seemed well.

Although being assured the car is ok, I still have this doubt in the back of my head because I saw the smoke and heard the couple of backfires.

So to you knowledgeable members. Should I be worried ?

Thanks

Dave

hi dave
probably nothing to worry about but keep an eye on the exhaust for blue smoke for the next 100 miles or so you may have cooked a gasket or oil seal if the temp got realy high if alls ok after that then alls good

Mine seriously overheated about 5 years ago, it had lost nearly all its water and there was plenty of blue smoke from both exhausts. I too was convinced that I had wrecked it but after replacing all hoses and the water pump it has been fine ever since. I have recently replaced the radiator too as it was badly corroded and the vanes were blocked, it runs even cooler now and is still fine.

The hose was in a bad state when I took it off (probably the original) The rad was checked and cleaned 18 months ago when at the same time the oil cooler was changed, some of the other hoses have been changed but not all of them so that will be the next job. I have noticed that it is running slightly cooler. I'm now feeling a bit p**sed off. When the oil cooler was changed, the garage that I used then (a Jaguar specialist allegedly) had the rad off because it also needed a new pulley, they should have picked up on the poor state of the hose, believe it or not the 2 jubilee clips for the hose and the rad bleed screw had only been finger tightened up, so I have been running the car for 18 months with them loose.
I think that explains why I have always had to put a 1/2 litre of water/antifreeze in it after a run. The front wheels were also put back on the wrong side. I'm now convinced that the jobs were assigned to the young apprentice that worked there with no careful check on his work.

complain to the garage telling them that you dont pay them to have a young whippersnapper putting your life in danger and that all work done in future is checked and signed off by a fully compatant engineer

Mick, I found a garage v/close to where I live so I don't use the other now and I don't recommend him. A real shame because what he doesn't know about Jags is not worth knowing. The final straw was when the car passed it's previous mot, he had gone on holiday at the time, the young lady came out with the keys and said it had passed and there was nothing wrong but they gave it an advisory on (wait for it) a rusty exhaust U bolt, I said "are you joking" she said, " It's nothing I know, but we have to be seen to be doing our job properly"

I took it to our local exhaust chap and he laughed and told me to go away after looking at it. Car passed it's last test last September with no advisories. Before they took it off the pit, I asked the tester (who I know) to have another look at the rear exhaust system at the brackets and pipe connections, his answer, 'perfect' nothing wrong.

It still surprises me that MOT assessors can be so variable. Guess that is the human factor (or the drumming-up work factor!). I have had similar experiences with both my Jags. Though I have now found a test centre that is more consistent now.
