Firstly Stop trying to get it started and change the oil, otherwise when it does start you'll end up with a rebuild.

Have you got a spark?

is it possible the rings are stuck after being sitting for a while? just trying to think how fuel would get into the oil, only way i can think of unless your head has cracked or rings/pistons are fucked. as said tho do a oil change b4 u do start it or disaster will strike, id do a compression test b4 anythin tho

bobbi96

yes i have a spark per cylinder, even checked the timing twice to make sure i had it right.

bobbi96

hiya mate, i have changed the oil, but it seems everytime you try and start it the petrol ends up in the sump in large amounts

Jimmyc

I'd try a comp test followed by a wet comp test, see if your rings are fubard.
Either that nd you're ridiculously overfueling.

bobbi96

could be possible with the car sitting for so long, as for the fuel ending up in the sump it has had a few people baffled now, compression test when engine is cold is good and same per cylinder, ideally would like to it started and warmed up to get a better compression test, before i start stripping the head off.

Hi mate the flap in the metering head is stuck fully open and causing it to flood. had exactly the same thing happen to me.It may need a strip down and rebuild. remove the air filter and you will see the flap stuck or very stiff

bobbi96

will give a wet comp test in the morning, also forgot to add when you turn the ignition on the fuel lines are whining any idea what that could be?

JoeE30

if it isnt the flap the roller pin that is on the other end of the flap is stuck/rusted/shitted up which is the same as the flap being fully open

bobbi96

hiya joe the metering unit was the first thing i went too, the flap isnt stuck its free i sprayed sum carb cleaner in there to clean out any dirt, but when you try to start the engine the metering unit is filling up with petrol.

would this explain the fuel in the oil, ive never heard of this prob s id be interested to kno incase it happens to me lol

JoeE30

Does the flap have any ressistance(spl) as the roller at the other end maybe stuck in its housing so even though the flap is free its like its full throttle?

JoeE30

the pin is on the bottom of the fuel line housing on the metering head

Jimmyc

And if the rollers ok, does the pin in the actual fuel metering unit itself move freely up and down, as i have found that when stood for a while they go stiff. Then the first time you start it up with any throttle the pin gets stuck up inside the unit and allows costant fuel as per full throttle?

bobbi96

i havent got a clue? has seriously got me baffled its a first for me aswell lol

bobbi96

good point joe, i noticed the flap was very free no resistance at all will check the pin first thing in the morning cheeRS

out of curiousity wot was the readin from comp test? u would have to be overfuelling massively to get past the rings

Jimmyc

Just reread this and i think i misunderstood what you said the first time round i've just said exactly the same but in different words, sorry mate

bobbi96

will hav a check first thing in the morning, if not looks like a rebuild was hoping that would be a last resort.

JoeE30

yeah its all moving parts that are subject to dirt an so on... the very same thing happened to me when i rebuilt my rs turbo many years ago, just luck my mate was an rs trained tech and jumped straight on it. we stripped it down, new gaskets and a full soak and clean and it was fine forever more..

Just an idea that might help...hope it gets sorted.

bobbi96

i had 145psi per cylinder

JoeE30

bobbi96,im pretty sure a rebuild isnt on the cards....i could be wrong but im 99 percent sure its the metering head that is playing up..... im not even sure if you can get gaskets for them anymore so be careful when stripping. good luck mate

bobbi96

cheers joe, help was much appreciated will let you know how i got on.

yh m8 145 is lovely so id say gotta be somethin to do with the meterin head

bobbi96

i am holding out on the rebuild till ive ran out of ideas, dont tink gaskets are available for the metering unit anymore, will hav to try out some second hand ones.

bobbi96

cheers mate hearing that ive got some piece of mind knowing the engine is ok, will have a strip down on the metering head and see if the pin is stuck.

Jimmyc

You can still get the gaskets i think as i only bought one about 6 months ago, the finis code is:1630674

mercgrey

id say metering head unit as the compression is perfect mate! also id check were exactly this fuel line noise is coming from if i were you

was they from ford m8?

Jimmyc

Is that aimed at me?
If so yes the gasket was a Ford jobbie

liam-rst

iTrader: (1)

yes m8 was 4 u sorry lol, looks like im off down essex ford tomoro then as i should do mine really, cheers bud

Jimmyc

No problem mate, you can still get all of the banjos and washers too, the only thing i couldn't get hold of was the bolts that hold the unit together as they no longer stock them.

liam-rst

iTrader: (1)

sorry for all the Q's m8 but did they wat the earth 4 them?

Jimmyc

I think it was about Ł50 all in, maybe less, was a while ago now and i've bought ALOT since then

cheers m8 brilliant

JoeE30

Any news.......Have you got to the bottom of this?

bobbi96

hey joe cheers for your help, you was right the pin had rusted in one place causing the flooding, i managed to get it running but its a bit rough sounds like its misfiring then when you turn it off it struggles to start again and the flap on the metering unit sounds like its back firing when tryin to start, you gota love these cars keep you well busy lol.
