About myself & new car problem!

[unlucky alf]

Hi all, New member & new Jag owner, I am one of those people who hates seeing cars going to scrap & would rather save them where possible, Anyhow I have just purchased a 2004 X type estate 2.0 diesel  which is very tidy for the year & good service history as a replacement for my old Rover 75 which got beyond saving (I saved if from scrap 10 years ago & got 80,000 out of her),

The Jag seemed the obvious choice as the look & size is very similar to my old Rover so when I saw one come up with no MOT that needed saving I jumped at it, I done my homework first on the bad starting, erratic tick over & smoke issue this one has & I thought I had it covered, (EGR problem was what I got from asking around).

So I set about getting under the bonnet today & removed the EGR & manifold, & sure enough the EGR seemed to be stuck solid so replaced it, Started the old girl up &, , , , , , , , ,dammit still the same, So my obvious question is where do i go next?, The smoke has no Oil smell to it so i guess that eliminates the turbo, The smoke looks kind of white in colour which to what i read is due to it running lean, I am sure others have got better knowledge than me so I am passing it over to you guys!, , , , , ,Many thanks.

Hi Tim and welcome.

For me you have not yet eliminated turbo issues. "White" smoke to me indicates either coolant in the exhaust from something like a cylinder head gasket leak or Oil burning which can come from a whole host of places. 

I would start by checking coolant level and condition. Basically you are looking for falling level and/or Oil contamination. If that all looks good I would be thinking Oil smoke.

I always used to try holding a white hanky over the exhaust when revving the engine to see what is actually coming out which might help.

....and just to be pessimistic whilst you are at ground level it is worth having a look at the state of the sills, not the outer painted plastic which will be fine but the metal underneath which are very prone to rust. Just part of the joy of X-Type ownership 🙂

Good luck,

John

Many thanks John, The guy i got the car from said that he had the sills replaced so i am hoping that worry is eliminated, Somebody did tell him that the smoke could be the turbo but as I cant smell Oil in the smoke I figured that wasn't the issue, But saying that my knowledge of turbo's is very little.

The coolant level is a bit difficult to monitor as the car isn't being used but a good sniff of the expansion bottle & a visual check shows no sign of contamination & no sign of custard on the Oil filler cap either, I will try the hanky thing & see what colour that catches, (hopefully not a pinky colour!) but smelling it it has a strong smell of diesel,

This is the first diesel engine I have had to attack as i have never had issues with one before so pretty much going in blind, As it is a right pig to start from cold I have ordered some glow plugs to see if that will at least help the starting problem, I will report back on any progress (if any) is made.
