When my car is under load it seems to misfire and hesitate then off she goes when the revs get up.
I took the earier accessable left two plugs out today and noticed there is oil around them...
Having done a bit of research on here would you say its the camcover gaskets? leaking oil onto the plugs thats causing this problem?

Looks like it mate, a new set of plugs would be a good idea too.
Are your leads ok as the oil can fry em.
-
I think the leads are ok, but will check when i do the gaskets..
New gaskets and spark plugs needed then..
The first spark plug i cant get out because its really stuck... any advice on how to pursuade it out, Will i do any damage using more force
Thanks
-
Mine were rather stiff but I managed to wind em out with the ratchet, I'm sure one of the more knowledgable ones will be along shortly to advise.
-
The staining on that plug suggests it may have a defective seal between the ceramic part and the metal :-/ Could just be from the oil though.
Either way, the cam cover gaskets need sorting, the breathers need checking in case this has caused the cam cover gasket failure and I'd put a new set of plugs in while you're at it just to be on the safe side. :y
Regarding the stuck plug it might be worth giving it a try on both a hot and cold engine. It may be easier to shift when hot.
A little smear of copper grease on the threads isn't a bad idea when you fit the plugs.

The engine was pretty hot when i tried to get it out so might just have to give some....
-
i had the exact same problem cleaned icv throttle bodie i had two pipes split changed them both still did it got a new set of plugs and the car run spot on now
-
I would be very wary of the ht leads, does'nt take much oil to fry them. Patchway Autoparts do set for a reasonable amount, Bosch from memory.
-
vauxhall leads are dear - but very good - beware of some non vx leads
-
blue magnecor leads are good but from memory about £130 inc. VAT - still cheaper than Vx ones which are approx. £90 PER SIDE :o

really? £180 for 6 leads? I`d be checking that dealer against another :-/

One thing i did notice is it misfires considerably less if i use SUPER UNLEADED or higher octane fuels?
Will be going to the VX dealer on Friday to get all the gaskets and new set of spark plugs..
Hopefully the weather will be dry so i can get on with it...
Also hoping that blasted Spark plug comes out with a bit more force... (could i use a lubricant down the hole ...WD40 or something?) or will that get into the engine and cause problems??
Would appreciate your opinions.

A squirt of penetrating lubricant around the plug won't hurt. WD40 is not a good penetrating lubricant, however, IMO. I'd use Plus Gas.
This will relieve any friction from the sealing washer but probably won't penetrate into the thread. Worth doing as it can't do any harm, and don't worry about a small amount getting into the cylinder. Try and spray plenty around the plug and leave it to soak for 15 mins before you try to remove it.

just been and got all the parts..... :o
All the gaskets, with spark plugs....£152.77!!!
that hurt!

rather hell, didn't you try asking for trade.
Got a set of plugs, cam cover gaskets & o rings and it only came to £70.32.
Have you tried asking your company mechanics if they can get you VX bits at trade it would save you a fortune.
-
just noticed i also got the inlet gaskets, which may not need changing they were £35
also in the rocker gasket pack there are two in the pack... and i got two packs totalling 4... do i need 4?...
will take the surplus back for a refund!
-
By two in the pack, I think it will be one gasket for each cam housing so yes you will need the four.
V0090511451 is a pack to do one cam cover, you need two of those unit price £26.60 each
V0090411826 o rings you need 8 of them per cam cover so 16 @ 14p each
V0009195109 spark plugs 6@ £3.23 each
-
got all those and the extra ones for the inlets... will take them back i think and recoup some money.
Thanks
-
No probs, you did get some black sealer didn't you?
-
yes... that was a fiver! hope you guys are around online on friday when i do this thing! :y
-
Print out the guide and you will be fine, just take it slow and methodical.
Next time you do it its a lot easier, and make sure you use a small torque wrench on the cam cover bolts if they are overtightened it will undo all your good work.
-
shoot..not got one of those.. will have to get one then.. hwats the torque setting?
-
Its only 8Nm. I got a little quarter drive one from fleabay thats great for jobs like this.
If you overtighten, the plastic cam cover will distort and cause a leak so it's rather important to get it right.
Better to find out now than when it's stripped down and you're stuck. ;)

Bloody `ell....... :o i was quoted "around £100" before a discount by my dealer when i deliberated over changing the leads on Bob Dents estate....not on trade but reckoned he would get me a wee bit off when buying some trade stuff.....
-
On HT leads, Autovaux quoted me about 20 quid (bit under as I recall) for 4 pot leads (Hella), so I guess maybe £30-40 for V6.
-
I DID IT!! ;D
Could not wait for friday so did the cam covers and spark plugs today..
Took me 5 hours on my own and all seems to be well... no misfire, idle is smooth and power seems good.
The breathers in the plastic part on the plenum were totally blocked, took about 20 minutes to clean them out.
the troublesom spark plug came out ok with a bit more force
The drivers side cover was easy the passenger side was an absolute Bxxtered.. those wires and spark plug leads made things really difficult..
I guess only time will tell if the seals are holding..just wait for that oil to seep onto the plugs again (stupid design)
Thanks everybody for your help with this, i am very pleased with myself at the moment..
:y :y
-
Well done Dean, told you you would be OK. :y
-
Please to hear it :)
The passenger side is more fiddly, I normally get Mrs TheBoy to hold cables out of the way.
-
I kicked mrs dean into touch ;) so no one around to help...but i did it eventually... I am just hopeing the the gasket did'nt move.. it felt ok when in position nothing bulging out of the sides. so fingers crossed.
Was thinking i wonder if some sealant around the spark plugs was prevent and oil from penetratign andcausing the problem?
