as the title says, my headgasket has blown on my 2000 v reg 2.5 v6 auto engine (petrol). its pushing oil out constantly now which is smoking and burning off on the manifold which is quite annoying.
i need to know what parts i will need all in to replace the gasket. i'm guessing that valve stem seals, rocker gasket, o rings etc will have to be changed and the same time. has anybody ever had to do this, if yes, could you write a list of what i'll need and where the best place is to get it all from.
if anybody needs any more info before they can help me with my problem let me know and i'll reply straight away.
thanks everyone

If the main symptom is just the oil leak it's more likely the cam cover gasket that has gone. The head gasket is below the level of the exhausts and would be unlikely to leak oil anyway.

I agree, have a good check of the rocker covers ;)
-
Do you have oil in the header tank?
Do you have oil in the plug holes?
If yes then for the first one, it is the oil cooler that has failed,
If yes to the second one then you have cam cover gasket failure and these are caused by blocked breathers on the plenium and oil vapour trap behind left hand cylinder bank.

thanks kevin, didn't know that.
gary, are you on about the spark plugs?
i have the oily-mayo substance all round the oil filler cap. its thick with it. the water in the header is cloudy but has no oil mixed in.
the oil is coming from the back of the engine on the drivers side near the brake servo.
does this bit of info help anymore?
thanks for your help so far lads ;)
-
sounds to me like cam cover gaskets have gone, sure fire way to check is to un plug one of the spark plug leads, the wells will be filled with oil. if your confident with diy car stuff can be done in a couple of hours.

Mayo on filler cap is most likely because you do short journeys...is that right???
Oil leak will be cam covers...plug holes will be the spark plug holes mate :)
-
Check your dipstick for mayo if its not on the dipstick it is what the other lads are saying

There is a 'maintenance guide' if you look in that section and it lists all the parts you will need including the correct sealent and it will tell you how to do it.
Goodluck ;)

Dont forget to clean the breathers at the same time, as failure to do them will mean you have to do them again real soon.

thought so, was just making sure.
all in for all of those parts from my vauxhall dealer is £165.
if i dont order:-
Gasket, Inlet bridge to head
Gasket, Inlet to Inlet bridge
Gasket, Inlet to Plenum O rings
which i may not need it'll come to £84
do you reckon i should order just the:-
Rocker gaskets
O-rings
Sealent, Black
and try my luck? dont really want to waste £80!!
-
Chances are the oil will have damaged your spark plugs and leads if leaking for a while so seriously worth thinking about changing them...if the leads are damaged they will end up taking out your dispack otherwise.

so i should change the leads aswell as all the other parts too?
-
My local factors do a lead set for V6, around £45, Bosch I think. I have used them on two cars and not had a problem. Vauxhall price for leads is terrifying.
-
Well you can try just cleaning the leads...
-
When you do the job.. where it says "remove the cable tray" .. make sure you do !! I had problems and tried to do it with the cable tray in place ... all that happened was I had to do the whole damned passenger side again ..leaked like a sieve on start-up .. with the cable tray still attached you can't get a smooth fit and will probably snag something like I did :(
Only good thing was having done it once the second attempt took half the time !!

by the way, is there any way of finding out what code my engine is?
its a petrol 2.5 v6, does that mean its a C25XE?

You can get a Vx Trade Club Card by joining Autobahnstormers for £20 p.a. Most Vx main dealers will then give TC prices on a range of service items and 10/15% trade discount on items not on the TC list.
I've recently done this work on my 2.6l. As Entwood says, do remove the passenger side cable tray completely and take your time.Double check at every stage.

make sure you have a torque wrench that goes down to 8Nm before you start disassembling things..
