running out of puff

[incisor]

took the red rattler for a 15klm run today to shake it down and clear the cobwebs.

at the 10klm mark it started hunting and died in the ****..

pulled over as far as i could and started looking for reasons...

none obvious so decided to check the sludge filter

drained and couldnt see anything amiss at all

main filer has only done 2 hours work and fuel appears clean so i doubt it would be that surely...

primed the system up again with the hand pump (which leaked so needs fixing) fired it up and managed to nurse it the 5klm home.

it has been sitting a while but i was running it for 15-20mins each week..

i thought maybe sucking air from somewhere or maybe cap not venting but couldnt really find any evidence of either....

any suggestions ?

[rovercare]

Pretty much the path your on, fuel filter, sucking air, trying to implode the tank, fuel line blockages....................fugged pump:(

[Blknight.aus]

unscrew the cap a couple of turns and try again...

if it still dies try changing the strainer in the bottom of the lift pump and yes if your lift pump is leaking while your pumping it it can allow air to be sucked in while its running.

to check for that crack the bleeder on the FIP or the filter and if it never stops spitting bubbles its usually the pump OR the oring on the sedimentor leaking.

Thats the thimble type condom type of thingymijig isn''t it? or am I thinking of something else?

Inc, might be worth while chucking a fuel additive to it as well, if it was anything like my fuel system it will be full of diesel snot, since the cleaning stuff went in I have been getting around another 100km's per tank.

[Blknight.aus]

no, its nothing like a condom....

its supposed to have holes in it to let fluid flow through.

unless youve been a lot better with your maintenance than Im willing to believe you have been or youve had your kids swinging the spanners you wont have gotten that particular filter out..... the engine mount is usually in the way.

and no dobbo having to change the oil in a component because youve replaced it after killing it while "playing" does not count as maintenance.

If it goes ten kays, then I'd guess the problem is more likely at the tank end than at the engine end.

You did not say if you got air out when you primed it on the ide of road, hunting sounds like fuel but on the off chance, you have not left a rag in the intake /aircleaner? ( have seen it before, more than once)

One time saw a Cummins in a drill rig go from 2100 RPM to 0 in one turn. Denim in the supercharger - broke the rotors and split the case. Put rag in back of AC housing to blow out dust, forgot to remove before putting element back in.

Yes I have been, all fluids and filters in the car were changed less than a fortnight ago. This included the cleaning of a mesh thimble sort of object funnily enough shaped like a Blknight that unscrews inbetween the engine mount and the bottom of the injector pump.
***** of a job getting it out ,F**k at one stage even my hands were dirty, it was from touching currency though.

Yes and no, I admit it is not preventative maintenance, but wouldn't your life be dull if all you did was preventative maintenance and no repairs.

Hey Dave

Is he a Clydsdale:D

Ray, I had to replace a s/c on one of these, (190 HP 24valve motor?) due to the plastic intake hose melting and sucking itself into the supercharger, then setting solid as it cooled:o
Stopped the engine and split the supercharger case.

Not a pleasant job.

Dont know what part your talking about dobbo.... Ive been through the Raves, the Series, stage and deefer workshop manuals, 3 different versions of the RPS, 2 dead tree versions of the EMEI's and an electronic copy...

I cant find a filter thats shaped like a greek god anywhere.

[incisor]

thanks for the tips, will give them a whirl..

I think dobbo was referring to Priapus.

Maybe Augeus is a better fit. I have seen your shed.

I had to look it up, but thats funny:D

Something I experienced some years ago with my Isuzu was the mesh sock on the bottom of the fuel tank pickup clogging up with lint and paint flakes etc. It started doing the same as yours and at 100k would die, get it going again and it would run ok at 80 but as soon as you got past 85 it would starve (and hunt). I did the elimination trail,1.sedimenter,2.engine filter,3.fuel pump strainer. When i went through all these I decided it must have been in the tank so I dropped it and found the sock clogged up. I removed the sock completely (tore it off) so that now the fuel sedimenter can filter all the rubbish and be easily changed. Its a time comsuming job removing/replacing the tank. Hope this helps...Bearman

I prefer your first one and had forgotten Augeus.


just for kicks I hunted down an old list of greek gods demi gods, lesser gods, ascended heros and mortals....

Typical...


Athena is the one that has all the characteristics that fit... shes a chick god....

Dang.



When I posted the post I expected people to bring out Mammon.

Inc, back on topic... Your problem may be that the hand priming pump seals are worn - as you mentioned.

Once, my primer pump rattled loose and popped up to the hand priming position. I could drive about 500m before it started coughing and spluttering. It took me ages to notice it had popped up...

Priapus was generally represented as a big p---k, not a man with a big p---k. I think the traditional representation is what dobbo was referring to.

Athena is not a good fit. You would look terrible in white dresses. Could be popular in the steward's mess though.

[Blknight.aus]

off topic....

thats true... but I think its very fitting..... kind of like the cars we choose to drive.


everyone else knows their crap...


but the few on the inner circle know the truth.
