VTS Problems **UPDATE REBUILD PICS PAGE 2**

[stevenet15]

Got in the vts as usual this morning and started it up, sounded like it had a slight missfire, took it round the block and it was sligish up to 3k revs, pulled back on the drive and poped the bonnet and the engine was knocking like a missfire it was also making a chuffing noise, i touched each of the manifold branches and they were all red hot apart from cylinder 2 which was only warm. put some new spark plugs in it and still the same, i was going to try coil next but does anyone have anyides as all the cars i have worked on with missfires have not made the chuffing noise that mine is doing?

thanks

Sounds kind of like the coil pack, could be a dodgy sensor.

[hesslevtr]

id go for coil pack or maybe the plug gap isnt corect

[SAM33R]

coil packs your next best bet mate, i cant see how a sensor would stop a single cylinder from firing

sam

[stevenet15]

yeah i am gona change the coil pack, i replaced the spark plugs and no joy, the only reason i dont htink its a coil pack is normally it stops working on two cylinders as the coil has two seperate coils and there linked to two clinders but i will try it and see. i think it might be fueling maybe the injector but i will also replace the fuel filter as its about due anyway, my car sounds like a motorbike at the mo with it running on 3 lol thanks for the replys

[SAM33R]

keep us posted mate, i think my pack is on its way out

sometimes i wish the germans made the saxo, atleast it wouldnt f*ck up every 5 minutes

[stevenet15]

ok i tried a brand new coil on it today and it didnt make one bit of difference. i took it to citroen as i wanted them to check if there were any ECU faults. anyway i took it there and they spent 2 hours on it, ran diagnostics and no faults are present, they checked over a few other things and still nothing and they also tried a new coil but nothing again. Its cylinder 2 thats missfiring so i could try swap the injector from cylinder 2 to cylinder 1 and see if the fault moves as apparently the saxo ecu diagnostics can only read power to the injector not actually read if it open or closing so it could be that he injector is blocked or fucked, the only thing is they said you cant swap the injectors from cylinders to cylinders as there coded but how true this is i dont know. Had one result of the day tho they spent 2 hours looking at it and didnt charge me jsut said i own them a favour as they all know me there, result saved myself a few quid but still gota ill vts

[SAM33R]

i wouldnt swap them incase they fire at the wrong time and you could have no engine left lol!

best bet is to switch the injectors but not the plug, unless there all diffrent then you got a problem

good luck mate:y:

[hesslevtr]

have u checked the plug gap

[stevenet15]

good luck mate:y:

lol of course i wouldnt swap the plug then it definatly would fire at the wrong time, i'm on about the injector itself not the wireing as i cant see how its coded to each cylinder, or i could put it in a jar and check the spray pattern

[stevenet15]

have u checked the plug gap

new spark plugs and i checked the gap :(

[stevenet15]

ok i am gona remove the rail and crank the engine with the rail over a bucket/tub and see the spray pattern of each

[SAM33R]

what is the plug gap? :oops:

[hesslevtr]

what is the plug gap? :oops:

cant think off top of my head is i ahve iridium plugs in mins so no need to gap

will say in haynes manual

[SAM33R]

o ok....

or do i just get matching plugs???

mine need doing

thanks

sam

[stevenet15]

i got tow sets ones 0.9 and the other is 1.0

[Strikevts]

take the rocker cover off and see if theres any funny colours on ur head gasket if not then go in on the valves only way is to open her up :(

Shame really ur vts is a baby to my vts :/

[Japman]

this happend to me mate with my vtr engine,changed plugs n leads but ended up getting a vts lump

[stevenet15]

REBUILD


i jsut got my compression tester back from my mate after months of asking for it, would have saved alot of hastle if he had jsut given it back when he should have, anyway compression tested it and here are the rough results:


cyl 1: 13bar
cyl 2: 5bar
cyl 3: 5 bar
cyl 4: 13bar

so i am losing compression in cyl 2 and 3, i dont think its piston rings as it didnt smoke and i have no fuel in the oil etc.., i took the cam covers off and had a quick inspection and it dont look like a valve has dropped or anything so i think its either headgaskette or cracked head between cyl 2-3. I've rebuilt a couple of vts engines now so i will wip it all apart and see whats going on. the good thing is i have a spare vts cylinder head (only done 28k and its complete with valves cams etc.. only paid £40 bargin)

i will be doing it over the weekend so i'll get pics up

[Strikevts]

Hope it all goes well m8. Shame about that tho reminds me of my fiesta zs when cyl 2 stopped and then the bottom end blew lol o well. Any way good luck with the rebuild m8 hope it all goes well :D

[stevenet15]

thanks mate should be ok as i've rebuilt it and another vts before but i will get pics up and keep you lot posted on how its comming

[argylefan1985]

What a shitter, At least you know what your doing with it all mate good luck with it all.

[Dan]

Shame your having to rebuild it, good one on having spare head.

[stevenet15]

ok i managed to have 2 hours free today so got outside and started stripping the engine, i managed to find the problem as listed below along with a load of pics of what i've managed to get done in the time i had:

in these next two pics you can quite clearly see that there is a problem with cylinders 2 & 3 from the colours of the cylinder tops:

and here is the bastard thats causing the problems, split headgaskette between cylinders 2 and 3, this was a new headgaskette only 5,000 miles ago but it was a cheap one off ebay only cost £35 including head, exhaust, inlet, valves and cam gaskettes/seals so i will replace it with a more expensive one or one from citroen (anyone know how much they are from citroen?) i'm glad its only the headgaskette and nothing to serious

[hesslevtr]

glad you found the problem mate

cammedvtr just bought a head set for his and he said it was £80 im not sure if it was from citroen or not though

[SAM33R]

what does cammed mean???

how does new cams increase engine power????

some guy cammed his furio and had 105bhp at the flywheel

[Dan]

Good work there steve.

[rob_s]

ot of interst is the head gasket a relatively simple job? if uv got the tools etc? is it just case of swapping the gasket? etc

this is for a punot aswell btw not saxo/106

any help would be good cheers!


good work aswell!

good work aswell!

if you have the corect tools and feal confident yeah it easy

only thing i worry about is the timing

id buy a haynes manual that will help you out loads

the head might need skimming aswell

[beardy]

sorry saw it was old post

[rob_s]

got a heynes,will have a look see later on!

the timeing shoudent be to mcuh of a prob as my boss has a timing lamp and knows how to do it etc,

feel confident enogh mayaswell have a go, the worst case if i fuck something up that badly il have to get an engine with can be picked up for about 200 (its only the 1.1 55s model)

cheers for your help guys!
