Help Please - MV6 cut out
« on: 12 May 2008, 16:52:23 »

Hey everyone - first post so please bear with me.

My MV6 (2000) has just stopped. The engine just cut out, had AA out, and after a while it started only to cut out again just down the road. Seems to be fine when cold but a nightmare when hot. Some observations.

Engine runs hot
Eats coolent
Drips oil but not loads
'coolent level' warning always on - if full or not
Had it 6 months, fine until now.
Alway run the fuel low - 10 miles to go - Could that be bad?

If anyone can help it would be so appreciated.

Thanks

Ok, welcome to OOF. :)

I am afraid you are paying the price for very poor maintenance.

Ok, if you constantly run on very low fuel level (ie vapours!) then you will have a very blocked fuel filter for starters so that needs changing.

Running hot and "eating coolant" mean there is clearly a big problem with the cooling system. Untreated this will cause a multitude of issues, especially in this weather.

Have you looked at the oil level?
Take off the oil filler cap, is there a lot of creamy goo under it?
Take off the header tank cap. Is the coolant (water) clear or more of a yucky brown colour and thicker than water should be?

I am guessing you have been topping up the coolant with just water?
This will be very bad if done for any length of time and can lead to oil cooler failure (gooey stuff in header tank) and head gasket failure (coolant loss, poor running, lots of creamy stuff in oil filler neck).

Also could be a blocked radiator causing hot running.

Coolant level is due to the sensor on the bottom of the header tank. Clean the connector and contacts under the header tank. Sometimes works, if not, new header tank (£30).

Finally, the cutting out may have nothing to do with all of the above. The symptoms you describe suggest the crank sensor is dying (very common fault and easy fix).

With yours being a year 2000 car, you might be able to do the "paperclip test" (look in maintenance guide). Do it with the engine running and let us know what codes it gives.

Oh, and the oil leak will be the cam cover gaskets leaking.

All of the above jobs are easy enough (Head gasket aside) to do and are covered in the maintenance section.
Your car needs a lot of jobs sorting, but the end result will be a car that runs so much better! :)

laidback has nailed it on the head i think! cutting out sounds like crank sensor my mv6 used to do it until i replaced it £50 there are 2 types of connector though and vauxhall are always wrong!

carry out the maintenance and the omega will give you a trouble free life! hg fail on a v6 is very rare but can still happen!

Thanks guys - garage did tests and it's the crankshaft sensor - apparently though both the rocker and head gasket are shot - is that potentially true? If so, I only do 3-4 miles/day would I need to change them urgently?

Thanks again

Result with the crankshaft sensor....

Camcover gaskets is a standard 'quirk' with the V6.  Always replace with genuive VX and not motor factor or E-bay examples otherwise they will simply leak again quite soon.

Head gasket - rare but not unheard of on the V6.  If its oil/coolant mix etc, check out numerous threads on the forum which will allow you to diagnose either head or oil cooler failure.  My money is on oil cooler, but also quite probably lots of short journeys where the oil simply condenses on the filler cap neck as brown mayonaise......

Okey, just had the proposed bill for Crank & cam sensor and a new heater valve - £390 inl labour - thought was a tad steep.

Any thoughts?

Thanks

It is VERY steep and why a cam sensor, its not a 4 pot, they never fail on the V6!

Guides on here to fix these problems yourself - look in the maintenance section.  Fairly easy to do and you'll save yourself a fortune.
