Xantia 1.9td hard to start in the morning, Help!
I have a 1.9td 1997 xantia estate which used to start reliably always. Over the last couple of months it has been hard to start in the mornings although once started it is great for the rest of the day and drives great.
Last year i had the engine rebuilt after bending a con rod when water got in the air intake during a flood. After the work car still drove and STARTED great.
Since this problem developed i have changed the glow plugs and checked they are charging, changed the air and fuel filters, changed the battery.
If i squeeze the primer pump till it goes hard I see fuel travel through the clear pipe to the fuel filter housing and then the car starts fine. (I also once had this problem in a bx diesel, why dont they put the primer in the cocpit?) So i assume the problem is air being sucked into the fuel line somewhere but I can not see anything obvious? How would I locate an air leak like that, if thats what it is?
Also if need be will I be able to continue primming the fuel line every morning if I can't solve the cause or is this likely to get worse until that doesn't help either and the car doesn't start at all.
Any advice would be gratefully accepted.

Welcome to the forum jereme
Yours is a very common problem and will almost certainly be the leakoff pipes perished and letting in air. These are the little black pipes daisy-chained between each injector and the pump return line.
Factors do a little pipe kit, including the little blanking plug for the last injector, for little money. Some branches of Halfrauds also stock them.
If replacing these do not give complete satsifaction, you have air getting in the fuel line somewhere else. As the fuel system is under suction, it'll never leak diesel but any small cracks will allow the admission of air. The primer bulb itself and the fuel filter housing are prime suspects.

Dead simple. Pull the old pipes off and pop new ones on Access is a bit fiddly on one or two injectors but apart from that, straightforward.

When this happened again on my old TD (the leak-off pipes had caused it once, then it happened again...) I finally noticed that when I gave the bulb a good squeeze, there was a faint bit of bubbly diesel coming out where the feed pipe goes onto the fuel filter (because I was putting it under pressure with the bulb). So, if fuel comes out under pressure, then air'll go in under suction. Nipped that up, ran fine again...

I have changed the leak off hoses and blanking plug, at least it was easier to get to than the glow plugs.
Have to wait till tomorrow morning to see if that has cured the problem.
While doing it I noticed that the head gasket is weeping oil very slightly especially if I touch it. The coolant is all ok and correct colour and car is not over heating. Anyone have any advice to offer. Not sure I want to spend out to have a garage replace the gasket if that is really nessaccary?
Would rather put money if I had it (which i don't) towards a picasso.

There's no pressure in there, so unless it's doing a torrey canyon then personally I'd leave it; others may differ, I don't think it's a big job at all - John's recent overhaul thread didn't even bother mentioning rocker cover gasket replacement....

me ?
I did change mine, as it was in the head set... but didn't mention it.. in my post or blog :O
changing it with the engine on the floor was a 1 min job....
i had changed it a few months ago anyway, in-situ, as I suspected a leak..
easy job, its only held on by 3 x 6mm bolts... but the inlet tract gets slightly in the way as do a few other easily removed pipes...
rubber gasket is only about a fiver.

John,
off topic...
Congratulations on passing the 1,000 posts mark
Back on topic, often when disturbing the rocker cover the breather hose between the rocker cover and the oil pot often splits. Replacements are readily available from your local stealer for under a fiver.
Part No. 1180 86 OIL VAPOUR HOSE
Worth replacing at the same time as the rocker cover gasket..
