conversion help (epic fuel problem) - Page 2 - Saxperience

The brown plug under the thermostat is unused.
Where I the vac hose off the throttle body plug to? Should go to the hole on the rear can cover iirc?

mlawlan69 · 26th February 2013, 20:14

I had a new head gasket/head set, skimmed...oil something's changed :$ too
new clutch (unrelated I know)
Cambelt was done too..

Ecu is a mark 1 VTS unlocked by bluehawk, and loom Is mk1 engine mk2 chassis but was spliced professionally so know that's OK too.

Honestly tom I haven't driven it enough to notice if the fan cuts in or not, sensor radiator and wiring is all brand new so technically it should do, I can't even afford to drive it even if I wanted to

1 check injectors and clean them they may be stuck open
2 sounds like timing is out
3 plug is the rad fan plug dont worry
4 carbon canistor is for emissions dont worry about it
5 i hear hissing, check for vacuum leaks
6 DO NOT DRIVE your defo gonna wash it if its that rich, and thats a whole load of expensive worms

Is there any differences between the mk1 and 2 flywheels? As in the tooth positioning/relative to crank position?
There is between alot of the other pug citroen models.. Of seemingly the same engine/management.

The return fuel hose?? Is it high pressure hose? Or just braided rubber cheap stuff. Because the cheap stuff allows the fuel vapour to permeate it. And shouldnt be run through the car because of that.
Could be causing you too look at the problem differently

K567 · 26th February 2013, 20:26

no difference in flywheel or timing teeth std 60-2

K567 · 26th February 2013, 20:27

where in leeds are you?

tillygti6 · 26th February 2013, 20:32

Thats what peugeot said.... To find that although the toothing and spaci g etc is the same they (the missing teeth)are 2 teeth further round.

It caused me epic ballache on the hdi's and actually altho diesels gave almost identical fault. Even getting the all clear on planet.

blackie_2k5 · 26th February 2013, 20:38

Flywheels spacing is the same

Are you getting a reading from coolant temp and Intake temp, as well as lambdas, and do they look sensible when it's plugged into the machine

Also check the fuel pressure reg

mlawlan69 · 26th February 2013, 20:39

I am now based in headingley as I have practically moved in with my Mrs.

The lad who did all the work told me it was cammed, I'm just not sure I believe it, I think its more likely he was getting annoyed wasting time on a conversion.

The return hose, I don't know but it is very very thick, so it would be hard to penetrate.

Marcus said all readings were fine so ruled out plugs, how would I check the fpr? Don't mind getting my hands dirty but I'm no.mechanic lol.

Sounds like the lad who did the work doesn't know what hes doing, so id definatly check the cam timing before doing anything else (since he had the head off). Just watched the video, sounds like it could be the timing out a tooth tbh. It's the fuel consumption that gets me, if the timing was out it wont help your mpg at all but from what your sayings it on like 7mpg at the minute, if there are no leaks id check lambda sensor/coolant temp sensors aswell, anything that thats directly linked to the fueling tbh

. I had a renault clio that was awful on fuel, put it on my emission tester at work and the CO was @10%

. I was getting like 10mpg and it stunk and it turned out the be a goosed lambda sensor, so it's not out of the question. Hope this helps

Watching this thread like a hawk, cheers for the input snake, any and all is greatly appreciated.

The lad is/was on here,he has his own company and was seemingly well liked and trusted etc, i have spare working lambdas so i can check that fairly easily

Nice one. Il keep my eye on this for the result, it might be worth leaving the battery disconnected for a while when you change the sensor, just to reset the ecu, as it might need to self learn/adapt if the fueling has been out for a while

tillygti6 · 27th February 2013, 10:53

Have you compression tested it mate?

mlawlan69 · 27th February 2013, 11:13

The head was pressure tested I'm sure, going to hopefully swap over lambda sensor today and reset the ECU.

To reset ECU its just disconnect battery for xx minutes/hours right?

Yeah it is mate, like 30mins iirc

shaneio · 27th February 2013, 20:56

That last pic, that pipe u holding don't got there, there's spose to be a pipe coming from the rocker cover to the inlet.

Is it just me or does your fuel line look like its not clipped onto the fuel rail properly?

shaneio · 27th February 2013, 21:01

Have you checked the o-rings on the injectors to make sure they all on properly aswell?

Hiya mate, yes I know that pipe shouldn't be there, its from the fpr and should be connected to a nipple under the inlet, however I cannot remove the inlet for some bizzare reason and I can't connect the pipe blind, there seemed like the only solution.

O rings I am not sure, I need to get the injectors off, but not sure what I should be looking for so may just be pointless

Insurance is up on the 5th, looking like I won't be renewing it

The vac pipe is there because The top half of the cam cover has been sealed to the lower part using tiger seal and there is no way in hell of getting it off to slip the hose over the take off. We tried for near on a hour.

For a start the spark plugs were sooted up to fuck so they were cleaned and replaced (Crush washers weren't even crushed the first time around) So were loose as fuck.

All readings for all sensors were fine on the machine including tps and temp.

Cleaned idle control valve and throttle body. Found a fucked up bolt holding the throttle cable in (snapped on the way home)

Map sensor was changed to the one from mine less than one month old same part number and still nothing.

We had the car running fine for about 5 seconds then turned it off and it fired up then started to do the same again.
