Hi everyone.I posted a topic earlier in the month reguarding a loss of compression on my 1.8LX 51 plate Mondeo.The fault was indeed a burnt out valve.Had it replaced at a garage for considerably less than I was quoted from someone else,however,after picking car up,the eng man light was still on and the tickover was very lumpy.The car just didn't feel right.Took it back to garage where a fault reader pinpointed a misfire on number 4 cylinder,the same one as the burnt valve.A new set of leads & a new coil pack were put on but made no difference.Compression test was ok but the spark plug from number 4 was caked in oil (again).They now have the car back & are replacing the injector o rings.Does anybody think this will help or is another strip down required?They ruled out inlet manifold.Think this saga is going to drag on :angry:
mintalkin
oil leaks onto spark plugs are usually down to an ill fitting rocker cover gasket.
Fordtastic
That wouldn't surprise me
Podzak
Er, was it the part of the spark plug inside the engine or outside?
Fordtastic
inside
mintalkin
if it was covered on the inside do you know if the valve stem oil seal was replaced when the valve work was done as a damaged seal will allow oil into the clynder.

or worn valve guide
Fordtastic
I would like to think they replaced the seal.They still have the car because they've sent the ecu away to be re-mapped as they now think this is the cause of the misfire.When the car was started and reved prior to the removal of the ecu,there was clouds of white smoke billowing from the exhaust.They said it clears when you start driving.Never smoked before,at all.

[/quote]mmm this subject would be interesting for a follow up my 1.8 mondeo has valve stem seal gone not loss of compression though dose use oil more noticable when running on engine like dwn hill thenthrottle dwn it puffs smoke..chatted to my dad he said they norm smoke more afterwards but please keep us informed

Hi Peter.Just phoned the garage where my car has been for what feels like months.They should be putting the ECU back in today so hopefully I'll get it back later.Will let you know how it goes,if it goes
ppeter7
ok mate thanks hope urs is sorted now fingers crossed
Fordtastic
Think it's gonna take more than fingers crossed Peter.Went to the garage where my Mondeo is in danger of taking root.Was told that the new,not repaired,therefore more expensive ecu,had been fitted but on starting the car there is now a misfire on number 1 cylinder.This saga is seriously testing my patience.The mechanic is now on holiday for the week,so wont be any progress for a while,not that there's been much so far anyway.Live and learn.
mintalkin
if the new ecu did not cure the fault do not pay for it,it sounds like the garage havent a clue with their lets try this next attitude,i would get to a different garage.
Fordtastic
That'll be easier said than done mate.They're not the sort of people you want to argue with.I knew the bloke years ago and certainly wont be using him again.Might have to buy an old banger for a couple of hundred quid just to get me to and fro from work til it's sorted.Can't keep ponsing lifts and walking everywhere.

[/quote]mmm i would just say look i want my money bk keep the car n go buy another i asume u have a warranty on it i mean if oil had got into plugs there still a issue cant see doing ecu would have anythink todo with oil on plugs.either that or they put oiley plug on no1.is it a 1 man band i expect mechanic gone ask sum1 else fix it 4 me
ppeter7
how ever if it was a bent valve i would ask them to change the valve guide that sits in the head chances are thats bent letting in the oil in 1st place i would have done mate
Fordtastic
Yes mate,bloke on his own.No warranty,bought the car somewhere else as a part ex.Don't want to spend a fortune on it coz it aint worth it but I do expect it to be fixed so I can at least use it.The time before when I paid him a visit,when he made enquiries reguarding the ecu,he did say that he'd put the oiled up plug in no 1 and it was still misfiring on number 4 and that he'd put an old coil pack on in replacement of the new one he'd fitted to see if that made a difference.I'm thinking maybe that has knackered the replacement ecu.He says he put the new coil pack back on pryor to starting the car.See what I'm up against.
ppeter7
yea he dont know what he doing by sounds of it mate. i cant seem to see why a oiled up plug would have anythink to do with ecu though,has he checked the HT Lead i know ur frustration mate sum places just like to spend other peoples money dont they,keep us informed mate
Fordtastic
He replaced the ht leads before he was advised that the ecu could be the problem.I think the misfire is a seperate issue to the burnt valve,just unlucky I guess.
ppeter7
yea seems like it.or valve clearance wrong .shame they havent got a spare coil or plugs that work to help eliminate even new can be faulty
Fordtastic
Hi mate.They sent the ecu back to where it was repaired to get it re-done.They tested it and said there's nothing wrong with it.He said he's going to get an independant technician to test it.I think I'll get him to put the ecu back in the car,I'll pay for that and take my car back.At least I can use it with a misfire.
ppeter7
yea true mate just see what happens m8
Fordtastic
Hi mate.Took the plunge and brought another mondeo today.Another 1.8 but it was very local and a reasonable price.Lets hope I have more luck with this one.No news on the old one yet.Bloody things sitting there with a full tank of petrol.Bummer.
ppeter7
yea shame u cant drain it out buddy.suppose thats the trouble buying old motores aint it.gd luck with new 1 keep us posted on other 1 buddy
Fordtastic
Hi mate.New mondeo is going back this week.Knocking,clunking noise from back end.The anti roll bar bushes were replaced for the MOT but that obviously wasn't the cause.Could be loose exhaust,loose strut tops or the dreaded sub frame :( No news on the other one so I'm going down there today to find out whats going on with it.Hope yours is going better than mine.Will let you know what he says.
ppeter7
aww buddy not good then.could be bushes on rear subframe??mine was bent and wasnt prepaired to pay the £300 quid ford wanted so got 2nd hand 1 delivered for £40 my local tyre company fitted and tracked it 4 2 cases of larger..sweet deal only went in 4 tracking.yea not to bad had probs with egr valve got 1 from focus st cple quid off ebay and was using oil but put sum lucas oil in £17 a ltr so put 1 in hey fingers crossed no oil probs lol.yea good luck with other mondee least they aint charging storage on it.
Fordtastic
Thankful for small mercies I suppose.No news on it yet.Still waiting for this independant tech to look at it.The new one has had new drop links fitted but still makes the same knocking noise (although not as bad) told the dealer I think it needs new subframe bushes.Gonna send his mechanic round tomorrow to have another look at it.Oh what joy
ppeter7
shame u cant take it off other mondeo mate becomes a pain dont it
Fordtastic
Hiya mate.Have finally got my old Mondeo back.It runs but it's not the same as it was.It's as good as it's going to get.Try and flog it now.It needs the radio code re-entering but can't ask about that on here anymore apparently.The other Mondeo is now sorted to,turns out it was just the anti-roll bar bushes.10 min job,all sorted.Happy days (for now)
ppeter7
http://www.radio-code.co.uk/ thats who i used.and cool glad its sorted yea happy days :ph34r: :rolleyes:
Fordtastic
Thanks for the web link mate,I'll give it a try.
ppeter7
ok buddy no probs,hope all is good
Fordtastic
Just put the old Mondie up for sale.Still starts first time,just got a slightly uneven tickover.Shame cos it's still a nice car apart from that.
ppeter7
sunds funny but have you checked egr valve ok or the flap on throttle body ok easy fix egr valve just undo the 4 screws on electric top part and press plunger to see if it gose down smoothly if not could need clean.throttle body flap wd40 around cable area then put some on clean cloth and wipe inside around the flap worth a shot and its free to lol :P
