Hi,

Just a quick update on the Discovery.... I've just got hold of an oil pressure guage and sender to test the oil pump and it's it's definately not doing much of anything (the pump... not the gauge!) My poorly Jag should be back this week so I'll get my local mechanic to check the bottom end of the engine and see if it's worth repairing or if it's best to get a reconditioned engine - I know the turbo's dead and needs replacing so it may be cheaper to replace the whole unit rather than costly repairs.

I'll let you know the verdict next week!

Yours,

Andy

Hi Andy, just a quick thought. If you have no oil pressure it could be that the oil pump bolt has removed itself (known issue) and if you were able to do it yourself, replacing the bolt would only cost you about £3.

I wish I lived closer as I have some in stock and could come and help you to do the job.

It just might could back to life if the oil pump was working again.

Dear All,

I managed to get the sump off yesterday as it was the first decent weekend weather-wise! I witnessed what can only be described as a triumph of mechanical engineering..... the oil pump bolt protruding 5mm from the sprocket and waggling around quite happily with no screw thread :mad:

Thankfully the pump sprocket was in perfect condition with no wear to the keyway or either faces - so I replaced the bolt with a new one I bought a few weeks back, fitted a new sump gasket, put sealant on the relevant faces on the sump and replaced the front camshaft gasket.

The engine fired up first time and runs perfectly apart from my musical turbo but I managed to order a recon turbo off eBay yesterday and already have all the gaskets. I've slackened all the turbo bolts whilst I was under the car using a breaker bar and long extension to save myself the hassle later....

I decided to treat the Disco to an engine clean to get all the grease and grime off the block, sump and transmission to easily check for leaks. Then smothered lashings of anti-corrosion under-seal along the chassis rails.... mmmmm gloopy....

I've re-checked for any fault codes and the only fault I have now is the front-right ABS sensor which I already knew about but no more injector errors thanks to the new loom.

I can honestly say I have dodged a really expensive bullet so I've ordered a new ABS sensor and am feeling suitably smug :rolleyes:

I can't thank you enough for all your help and advice.

Yours,

Andy

Hi Andy,that's great news about the oil-pump bolt and the running engine.

If I may can I suggest you do a full engine oil and filters change asap - just in case there's any bits floating around.

Hi,

I did take the opportunity to examine the cylinders using my trusty scope and everyting looks fine with no scoring and there is no apparent play at the bottom of the conrods. Also, the camshaft looks in good order so I don't think there's been any top end damage.

As I hope I'm over the worst I thought I'd get some decent 5w 30 oil and also some ZX1 treatment that I've used in other vehicles.... it's great stuff.

Yours,

Andy.
