A little tip for all you 16v drivers....

Post by Kitch » Sat Jul 09, 2005 6:46 pm

If you didn't already know this, listen up.

If you happen to be entering a bend which is nearly a complete circle (we're talking 240 degrees), you happen to be doing 7000rpm and you happen to have the red mist....take some time to cool down and ease off. If you you press on and see the STOP light start trying to attract your attention then you really should stop pressing on. It is not the sensor in the res wondering where all the LHM has gone. Its because this is happening....

And to find this out, the only realistic way was to do this.....

And this....

And because of this, instead of enjoying the car I can only look at it, as it looks like this...

As James May would say....."Oh cock!!"

Glad to see that you are getting on with it. That is a really nice car so take your time rebuilding that engine. (Don't do what Tony Isaacs did with a Saab. Protected the bores with rags and then put the head back on. The starter motor said No!)

I take it you are now baffling the sump as has been recommended by us what sorts track cars for a while now? :oops: :oops:

It is pretty confused already but it would certainly be a very good idea!

I've not fitted one funnily enough. Two reasons for that....I'll fit one later one, but for now it'll stop me driving like a nad around corners. Secondly, I'm very lazy.

There used to be a system sold for racing jaguars which was a hydraulic accumulator for the engine lubrication system - sold as an alternative for dry-sumping. The system simply filled an accumulator (and we all know how they work) and if the pressure fell, the accumulator provided a few seconds back up.

It may well be that one of the competition specialists sells one - and in fact the obvious place to put it would be on an adaptor on the oil cooler - which could be nearly universal.

tell me ig im wrong but isn't the same system also used to prelube the engine before starting up? basically squirtting oil upto the top of the block to make sure its all wet before turning the enigne over? seem to think they work much the same with an accumulation of pressure/oil released on starting the eninge?

so it was you who put these ideas in my head! Alan you hav to stop it, while all these little things that i seem to retain are both interesting and usefull i only hvae a limited memory and i'll start to forget usefull things like how to breathe ;)


Have you used/seen these things in action before? Sounds like a brilliant idea i just wonder if it does work of not!

Never seen one in action nor spoken to anyone who has, but this Chris Longhurst seems as though he's no mug and as we're into BXs this guy seems to be just as far into the things that make cars and bikes go for as long as they do, so if he endorses it, I'd be inclined to accept it as gospel.

Incidentally, I read somewhere the other day that the amount of oil in these crankcases is really below their true capacity and that they will take up to 1 litre more than is shown on the dipstick. Might be correct and may stop this problem Kitch has had but I'm not prepared to risk a clutch to find out.

Jaguar engine still looks good after all this time doesn't it!

Just after I finished the last post I did wonder if some of the previous owners of this car had been in the habit of running it with low oil which would tend to accentuate the surge problem. Was there any indication from the gauge and was the pressure good?

Whilst I understand the startup theory I've never really heard anyone consider it a problem before. I suppose if you were worried you could to some extent help by putting a switch in the fuel pump circuit so that no fuel was delivered until the oil pressure had built up.

Alan I suppose you could determine the oil level roughly by the dipstick. I suppose the critical bit would be that the oil level was below the crank seals at all times when the car was stationary. Any oil getting past the seal should drain out of the housing but an additional hole drilled in the cover plate could help. What I'd be concerned about whould be churning causing the oil to froth.

Hello people this is my first post! You may know of me from the Andyspares forum.

Gosh ive never heard of that happening on a four cylinder inline engine before. I know a lot of flat engines suffer this problem.
