picked up the partners new car yesterday a 2000plate 2.5 cdx and i have noticed a slight missfire under load, drive it gently its ok anything more it feels like its on 5 cylinders, i spoke to the previous owner who had it 2 ish years and he never recalls it having plugs changed, would it be a safe to assume that its most likely the plugs are knackered?
-
Plugs, or cam cover gaskets have gone and the plugs are full of oil! Wip out the plugs, at £1.50 each they are cheap as chips :y
-
had the same on mine it turned out the leads on passenger side were arcing new leads and now running spot on have a look at leads at night with engine running see if you can see it arcing :y
-
cheers guys, hopefully a set of plugs will cure its in at the garage tues to be sorted :y

EXACTLY.... my problem... Mr Tunnie....pedal trick revealed 0...3..0....0 and 0..3..0...5 codes
Plug 5 full of oil..... :'( :'(
-
looks like you guys were right about the camcover gaskets 2 out of 3 plug holes on each side have oil in so new cover gaskets are on the way :'(
-
And clean the breather system or it will happen again... :y
-
yeah my mechanic guy said that he will clean the breathers, replace gaskets, replace plugs, replace the knackered battery and do a coolant change as the coolant when tested was only providing protection down to -5 to -10 which isnt anywhere near enough in the present conditions :o, cost £300 all in

Genuine, or you`ll be wasting your money. Don`t forget the "O" rings as well :y
-
garage gave me a price i agreed so will leave em to it if it leaks again i the future thet will have to sort it, but having said that he is my trusted guy who does work on all my cars including my last car a track prepped m3 so he knows i want it right
-
whoo hoo she's back on six, new plugs, new cam cover gaskets, and all breathers cleaned= one happy person indeed ;D

Still ask them what was done with cam seals. Pattern seal, bathroom sealant, instant gasket will all give trouble and further bills in future. You need to know.
-
genuine seals as far as i'm aware, no sealants, silicone etc used as i was told this can lead to more problems than its worth :y

Bloody things run for a couple of days then the missfires back, no fault codes, definatley confused now, suspect it may be coilpack or leads,is this a fair assumption? :(

either really, oil could have broken down the leads & in turn affects the coil/disspack.
surprised you havent seen me kicking around burton tbh. blue mv6. ;)

think its going to be replace the leads and coilpack tbh, might as well do both at the same time cant see the point doing one without the other. Can't say ive seen you round burton but only had the car a week or 2, will keep me eyes peeled, although the partner drives the omega mostly tbh :y
