Recently bought a v6 omega for drifting,
was driving it normally (on roads) and a slight vibration noise occurred
then the car cut out luckily we were already home so we were doing 2-3 miles an hour tops!
when we tried to restart the car it sounded wet and slurpy, with no metalic noises and thuds etc
so im lead to believe that the cambelt has slipped one or more teeth, as its still intact
bought a new cambelt but what else can this affect?
is it a matter of a full engine rebuild or what not, and i was to to do this would the imobiliser affect anything #
many thanks in advance

have you tried turning engine over by HAND to see if any resistance is felt :-\ ie: any resistance may point out any internal damage bent valves etc :-\
-
the cambelt tensioners can fail so it may be worth looking at them :y

On the V6 lump it is hardly ever the belt which goes but the tensioners which fail so before you do any work you need to see how far the belt has slipped. For this you need the locking kit, dont beleive anyone who tells you that it can be changed without.
Also, what evidence do you have to support that it's the belt? If it has slipped enough to cause the engine to conk out then I fear that the damage to the the heads is already done. But without proper investigation you cant know for sure.
There are many reasons for the V6 to suddenly stop, the crank sensor is notorious. Also to take in to consideration is the age and milage of the current belt and tensioners, if over 40k then they need to be changed ASAP regardless of the cause of the fault.
I am sure there is a member in the area who can help you who has the locking kit and a modicum of ability with Omegas. 3 pop in to mind straight off the bat in fact. But there is a lack of OOF mobile mechanics in your area. I have covered it a few times when people are reeally in need but I dont do it regularly.
In short, you need to be sure it is the cambelt before going through with a cambelt change, but even so if the cambelt is ok but over the 4 year/40k mark then it needs changing along with the tensioners and with the correct tools.

Thanks for all your advice now in process of removing cam belt cover which seems a major task in it self havent as yet disconnected the battery as worried about how this will effect the imobiliser so any advice on that would be truly appreciated.The engine turns over but has no compression or very little and gives a slurpy wet sound there is no nasty metallic noises.Havent touched a motor in the last 20 years but the boy is now into driving and we went to a drift meet couple weeks ago an both fell in love with it,hence the purchase of the omega which iccidentally is of "The Bill" fame. So you will find i will be asking loads questions on here, thankyou all in advance.
Cheers David

Not good ...... not good at all ... :(

I cover the whole of the UK, but the travel costs can be prohibitive, in cases when I can't be certain what the problem is / what the fix will be, without looking at it first.....
-
On the evidence of your description it does sound as though you have a few bent valves.
Disconnecting the battery will not have any effect on your immobilizer but may cause the alarm (if fitted-I guess the Police rip them out) to sound for a while, avoid this by removing battery terminal within 15 seconds of ignition off.
-
Well at the look of your replys it dont sound to good! Well advice please would it be best to rebuild the engine or put a new lump in, there is 1 available 5 miles from me for £300 but its a 3.0l will this fit straight in with little or no hassle and would it be economic to do so? cheers

Depends what engine you have now. If you have a 2.6 or 3.2 it wont slot straight in.
Whereabouts in Essex are you ?
-
I know this not trading area but if you have 2.5 in your car drop pm to albs hi have 2.5 engine with low milage and hi is essex, really good bloke :y
-
i have a 2.5 engine aswell could drive it down as working near essex :y
-
Thankyou kind sir. :y..............he already has. :y ;D
Hes collecting it Weds. morning. Even if the original engine is salvagable in some way,a spare is always useful when thrashing the daylights out of them when drifting. ;)
