Hi all, a few weeks ago I noticed that occasionally the Trooper would be a bit of a sod to start from cold about one time in 6. Just been away in the caravn for a week and 2 out of 6 days it was a sod from cold. Once started it runs perfectly.

I've checked the servicde receipts and last year it had two glow plugs replaced. How many are there (I thought 4) and shouldn't they all be replaced at the same time?

I'm assuming that this could be my starting issue but not being that knowledgeable engines may well be barking up the wrong tree.

It's in the dealers tomorrow to have the injectors replaced (recall) so maybe I should ask them to check the plugs whilst they're at it. Anyone know how much this would cost?

Any advice appreciated.

You've had no ther running problems? Then I think the first thing to check would be the pick-up pipe for the high pressure oil pump. Easiest way to check it is to overfill the sump by 2 litres and see if that "fixes" it. If it does, have a new pick-up pipe/strainer fitted because yours will be cracked.

While they have it they will have Tech 2 (the dedicated diagnostic tool) connected so get them to check around, with particular reference to the Oil Rail Pressure Sensor, although with no other symptoms it may be a little unlikely that that's faulty I guess. There are plenty of other sensors and things which they could check whilst they are there..... Wink

No other problems whatsoever - would the cracked pipe not cause a more frequent problem?

It also had an oil pressure sensor rail fitted last year so chances of that going faulty in short time are few I guess.

Where does I find the pick up pipe so I can have a visual check?

Well, not necessarily. I had one crack on me recently - only it was the engine lube pump, not the high pressure pump (which powers the fuel injection system) - and it started off being just once in a blue moon it wouldn't pick up pressure straight away. I guess it depends how big the crack is. Gradually it gets bigger so it sucks more air until it can't pick any up any oil at all.

I didn't think it sounded like the pressure sensor and even less so since you had a new one!

You can't visually check it - you have to drop the sump! But doing the test I explained should at least prove/disprove it.

Sounds a bit hit and miss to do the test as it is only one in about 6 mornings when it is difficult to start and I guess that running it for a few days to make sure with 2 litres of extra oil isn't advisable?

I ran mine about a couple of thousand miles like it until I got round to having it fixed........... Wink

I'd do it and run it at least until you absolutely know for sure whether you've had a result or not.

Don't over over-fill it, though, because that can be dangerous.

Well i'll give it a go - so I need to pop 9 litres in after oil change and then drain a couple out once proven. Thanks for your help!

Why don't you just chuck a couple of litres in now - BEFORE you change the oil? Then if it's proven a cracked pick-up you could replace it and do the oil change at the same time because the sump's going to have to come off to do the job so you're going to lose the oil anyway. If it doesn't prove a cracked pick-up then carry on and do the regular oil change and dump the excess oil in the process.

Just a thought. Wink

Good idea batman!

If it is a cracked pipe is it easy to replace or is it off to a dealer?

It's about an hour's job for a man accustomed to the spanners and who has a ramp with a lifting beam - you have to drop the crossmember and then the sump pan.

Dealer then! I don't mind using te odd spanner but dropping crossmembers is a bit far for me.

Incidentally, Troops went in for injector replacement today and the new ones were faulty so they're getting some more in for tomorrow and left me with a Nissan Almera - eurggh Crying or Very sad

Cos after they had put them in the exhaust was blowing smoke - don't know the first thing about injectors but I found it unusual that a new set could be faulty? Owt's possible I guess!
