Diesel spill pipes

johnnyecosse · Dec 2, 2009

Just been out and changed over the 3 diesel spill pipes on 97 300tdi to see if it cures starting problem - difficult if left for more than 6 hours or so then starts 1st time every time - fingers crossed n all that! Question is regarding blanking cap / end stop whatever you wanna call it. There wasn't one fitted and I dont know where I'd put it if I needed to. The last injector (nearest bulkhead) looks sealed anyway at the end. Reason for asking is I've dropped the blasted thing I got in new kit and cant find it anywhere. Do I need it?

run the engine, then you'll see why it's needed

Engine running fine - no leaks now or before - as I say end one looks sealed to me and must be or diesel would pee out! I'll post a pic in 5 mins

so which bit have you dropped ?

johnnyecosse · Dec 2, 2009

Dropped the wee end cap thingy but dunno if I need it or not - I dont know what purpose it would serves as there wasnt one there before? Unless I'm missing something.

i think it will be the rubber blanking cap that you get with some kits.

if you find out you do need one,but cannot find/get one.just use a bit of new pipe and fold it over then use a cable tie to keep it folded.

Hopefully - pic shows what I'm talking about. This is the last injector connections - different from other 3 as LHS is not open. So - no blanking cap required? Just want to be doubly sure I'm not missing something obvious here.

that's a old one so no blank cap required - fuel would have been weeing out else

johnnyecosse · Dec 2, 2009

As I thought - not required - just wanted to be sure there wasn't something hidden away anywhere. Fingers crossed we'll have a first time start tomorrow! Thanks all

Why should leaky spill pipes affect engine starting? I've never come across that in 40yrs messing about with diesel engines.

johnnyecosse · Dec 2, 2009

Perished pipes allow air to seep into system overnight - making 1st start after a period of time has passed (in my case about 6 hours or so) very difficult. Hopefully new pipes will be airtight. I dont even think you would necessarily see fuel leaking out - more a case of air leaking in. Make sense?

If renewin' spill pipes always replace the copper washers anaw

johnnyecosse · Dec 2, 2009

Naw - cos these were just the rubber type. I think youre talking about the rail type.

D'ye mean like these?.....

johnnyecosse · Dec 2, 2009

Yeah - that's what I'd call the rail type mine were just rubber hoses.

Yes, makes sense. Never had it happen on any of my diesels. Maybe I'm just a lucky b----r.
