Evening all, I recently acquired a 57plate tdci 1.8 90ps connect, which is in really good condition for its age, however I have a little niggle....when cold it mostly starts within a second or so, but sometimes takes 5 seconds of cranking before it fires, and after it does ( no matter how long it takes) it runs slightly rough / lumpy and blows blue smoke until it's been running about a minute or the revs are held up for a few seconds, then it idles perfectly and dosent smoke at all. It will then be fine all day, and dosent struggle to start at all until left about 4 hours or more to cool down significantly, then the smoke and rough idle and sometimes slow starting starts all over again.
My first though was air ingress / fuel running back as had same issues with Vauxhall combos, but not sure if it would be a lot harder to start? I've changed filters and oil, made no difference at all, and done leak off test as mileage is 184 000 and nothing significant showed up, so not sure if someone already did injectors or I'm just lucky. I have no service history at all so no idea if any things been changed.
While driving etc. there is no fault at all the engine, no smoke, no power loss, etc....only repeats issue when left for several hours. I have done code read on IDS and nothing showing, yet my maxi diag scanner repeatedly comes up with glow plug circuit low fault, and after clearing returns on next start up lol.
if I fill it right up with diesel it drips underneath till down to about half a tank, but looking at tank it looks new and shiny plastic, so think it may have been changed recently, and hoping sender isn't seated or sealed correctly. My first thought was bad o ring in a pipe on the sender, which could also cause air ingress to start off, but have kinda ruled that out due to leak stopping as fuel level decreases. so hopefully when I get a chance to drop tank that will be an easy fix, and nothing to do with above issue.
I love the van, but don't want to start off with engine issues lol. I do have slight niggle regarding steering / rack but I'll start a new thread for that.
oh and the main battery positive lead decided to part company with the lug on the starter today so I'm now having to repair the loom by cutting it and fitting two big ring terminals to the main feed and alternator ends of the loom to bolt back to the starter terminal
