I'd also check to see if there's any fuel in the inlet plenum.

A mate of mine had the exact same symptoms on his 3 door and it turned out that the diaphragm in the fuel pressure regulator had split and fuel was being drawn up into the inlet via the vacuum hose.

Just something else to check.

Not sure if you should do this but I have been told in the passed to remove a plug at a time from an injector and this should high light the cylinder if it is getting fuel or not. Also remove the leads one at a.time. this will tell you which cylinder is being a.dick. the ignition amp should be fine. I re greased it as well so thst wss all nice. Might be a gap size on a plug.

This happened to Rs Sids saff! He couldn't find out what was wrong and said he thought the engine was fucked. When he started to strip it, he took the inlet manifold off and it was full of fuel! The engine was fine though fitted a new fuel pressure reg and its been fine since

I would try this too then you know which cylinder has the fault on it.

Well guys, When i could be bothered to take the plugs out i found a problem...

As you can see!



i also see they are not genuine plugs, i wonder if there is any other damage though, obviously atleast the bit of the plug has to be somewhere in there! I wonder why this would have happened.

Obviously got too hot?

Thanks for your help guys.

Glad ya found the fault it did sound plug related, densos are a poor quality plug IMO may have got hot and broke off

jonfoc

Heard lots of horror stories about Denso plugs melting and wrecking engines. Fingers crossed not too much damage.

Ebonycossie4x4

iTrader: (4)

yep ive heard all the stories about Densos too but didnt realise they was in there,,, Should have checked.

So any chance at all that the engine isnt fucked? lol

ive ordered some 071s from Matt Lewis but im not holding out much hope, i dont have a comp tester but good chance this cylinder is knackered isnt there?

jonfoc

Well it's got to have gone somewhere. Chance in a million of it not doing the bore, piston, valves, head. If it has popped straight out, next stop the turbo!!! I'm not a pessimist but I think it's going to cost you pal.

gingerturbo

iTrader: (2)

Use a bore scope and look for damage

Fil

dont about how knackered it could be, but I do have a compression tester you can borrow if required to check it out.

gingerturbo

iTrader: (2)

You may be lucky and it might still be in the bore

GVK.

If you're lucky it's embedded in the piston, if you're unlucky it's gone through the turbo etc as above.

Have heard of Denso plugs doing the same on VAG 1.8T engines.

Ebonycossie4x4

iTrader: (4)

i drove it home for about 6 miles so i doubt its still in the bore.... i dont have a bore scope to check.

Thanks Fil your pretty damn local too!

i have heard of this happening to people and it being fine but ive also heard extreme horror stories lol! I had considered it dead anyway so if it isnt then result, If it is then im only where i thought i was anyway.

booner999

Fuck! Was not expecting that. What cylinder was that on?

Ebonycossie4x4

iTrader: (4)

car was still coming on boost, although i only brought it slightly on to test if turbo was ok, theres no blue smoke at all and no really horrible noises, other than the running on 3 of course.

pity there isnt an old plug in my garage just to test but ive looked everywhere

Nothing wrong with the correct denso plug for the correct power.

Ive got a bore scope if you wanna look to be on the safe side, honestly I wouldn't try a plug as yet just incase it has heat seized itself to the piston and as soon as you fire that cylinder up it will free itself

jonfoc

Get a plug and practise the theme tune to The Great Escape, you never know your luck.

jonfoc

Good point, ignore me

where abouts are you mate? any where near me?

gingerturbo

The other side of the water, Orpington Kent

Ebonycossie4x4

iTrader: (4)

ah ok thats a pity i would have popped round and got it off you, if its embedded in the piston it wont stay there then?

what are the chances of it just completely melting? zero i suppose.

gingerturbo

iTrader: (2)

Depends on the composite of metal they use, it wouldn't of melted completely but may have reduced in size, by the sounds of things you might of got away with expensive damage, I could pop round after work this week unless your in a rush to know the problem

Ebonycossie4x4

iTrader: (4)

thats really nice of you mate, nah its only sitting anyway and ill have the plugs by then so maybe we can chuck them in straight after you have had a look and hope for the best.

i know im away a couple fo days this week though but just dont know what ones yet.

gingerturbo

iTrader: (2)

As mark mentioned earlier which is the main problem with 90% of all cars, plugs people just throw in a recommended spark plug not taking in consideration, air gap, heat range and even electrode type? Make sure you pick up the right set for your engine spec

gingerturbo

iTrader: (2)

No worries just pm me the evenings your about and ill work around that

Mark Shead

I cant see the cross reff on the plug but on the plugs I use is a IK24 heat range so that plug being a 16 could be way to hot.

Mark

ajamesc

Never done me any harm at 2.5 bar of boost driven hard when ever used lol
I guess the plug only works well with a good set up!

Mark Shead

Its easy to blame a plug as it cant talk back esp when its dead lol.

Mark

delbee1

What power levels do you use the IK24 for??

Mark Shead

360hp for 24 and 27 upto 700hp and 31 for over 700hp+.

Mark

Thanks very much

So these plugs could be completely wrong then mark?

Ebonycossie4x4

iTrader: (4)

Big thanks to GingerTurbo for coming round and looking with the boroscope!

first impressions are actually quite good with some detonation marks and a small splattering of small metal particles embedded in the middle of the piston which believe it or not actually seems a good sign.

we think it could be ok and the bore looks quite clean, i will wack the plugs in and see how it runs.

If its fine then i will get it up on the ramps and start stripping front bumper and underneath of the car to go back 4WD.

Fil

sounds good.

but if your taking it off the road to 4x4 it. is it not worth the small extra time, taking the head off and inspecting it, as a new head gasket and cam belt can't hurt for not much money

Ebonycossie4x4

iTrader: (4)

right,

Spark plugs are in and it doesnt look good. Runs a lot better but hunting and not running properly thats for sure! plug number 2 keeps getting oily and when removing lead 1 or 2 it changes nothing in relation to the revs or anything.

obviously there is damage in there, its true you say that though Fil. time to strip car down i think and start building it up better than before. there are lots of things im not happy with anyway so ill start stripping when i can be bothered lol.

Watch this space!

Such a shame I was hoping that you might of got away without any damage
