Not just on this punp, altogether even with 9mm, current pump ws bench tested before it went on

[darrenjlobb]

Its ran out of derv 6 times? Youve probably nakkered the vane pump then, diesels dont like being run dry.

Heh good point, steel on ally dosnt go well without lube!

But on a serious note, James has a point here, try going a 1krpm idle return test and see how much you measure, if its way down, you acaully have just got a shot vane pump....

[padge]

How would i do this?

[darrenjlobb]

Pull the return pipe off the pump, connect a spare hose and meter it into a mesuring jug for 30 seconds @1krpm

[padge]

Set idle to 1k yes? What will it measure if its good?

[darrenjlobb]

Just get someone to hold it or set at 1k, and measure 30s worth... Then pm me the ammount

[padge]

Might do that tommorow then, thanks darren.

[padge]

well, 2 bolts on the inlet were a bit loose, tightened them up and gained about 2/3more psi, feels a tad more nippier, still dieing off though, going to change underbonnet filter tommorow.

car's a shed . . . . . . . . .

[padge]

i know this lol.

[Ruan]

It's gotta be fuel related, so hopefully it's a relatively easy fix... You never know actually, it could just be a nasty air leak, and when the lines are under heavy suction, it pulls air in and drains the pump housing...

Is it even a slag to start in the mornings?

[padge]

No starts easy as hell all the time, bit lumpy but it always has been

[Ruan]

But it does miss a little?

Sounds like it could be an air leak in fairness...

[padge]

It has been in my mind, yeah misses etc

[darrenjlobb]

Meh doubt it, probs just more timing on that front, if its leaking air like that itl be much worse in the mornings / not start for ages etc...

Measure your output...I did that tom guy off here the other days car, which had 3 seized vane rotors, which meant it worked perfectly to 1500rpm, then stopped dead on the power... literally because it couldnt flow any fuel up from the tank....for all you know you may have a worn vane pump / seized rotors also...just not as many...I know it was rebuilt, but dont trust anyone these days, the vane pump is the last bit to come out, and often ignored.

exactly what i said yesterday to Padge, worth checking out at least . .

[padge]

i mentioned doing both filters to try eliminate those, changed the filter under the bonnet today, and sorted the dodgy idle out, left it for a bit, went to subway and BOOM! pulls as much as i dare take it in 3rd, not enough room for other gears.

[Dave]

So all sorted?

[padge]

aye, seems so dave, going to wind more fuel in tommorow.

[Jenkosowls]

What does it pull to with the gov? As mine should be similar

[padge]

well, took it to 4.5k easy and then let off, that was in 3rd

[padge]

So turned fuel uo today and its doing it again :/

[Dan!]

How far have you driven on the new filter?

[padge]

About 40 miles

[Mattcheese31]

So turned fuel uo today and its doing it again :/

drawing air in mate . . . . . . . .

[padge]

why isnt it hard to start then? it starts up everytime easily, no struggle.

Mine is exactly the same, starts perfectly but it idles like shit when its cold! if you hold the revs at ~1200RPM does it idle fine?? If so its Identical to mine, its been like that for ages (ask Ruan), I even sealed the filter housing and I have now given up on it as its doing my head in

i refer you to my previous message on facebook the other day . . . .






Monday:Matthew David Ferguson
i'd check it out though mate
higher up the revs, flowing more fuel= more vacume=more chance of pulling air in, it's happened to me, just feels like hitting a brick wall . . . . .

[Dan!]

Not just a pretty face ^^^^

[padge]

Might try find any leaks today
