Hi all, I would just like to say thanks for all the advice on my latest purchase running issues, ie running lumpy. I did renew Plugs/Coil Packs/Cam cover gaskets and even bought a new Thermostat. Now I need some more help in getting someone to do a Cam belt/Water pump change, too much for me to attempt. I live in Feltham, nr Heathrow . Daz, Darth Loo nee done one for me about 17 years ago. A point in the right direction would be very much appreciated.

If you get the parts I will gladly assist in about ten days (once I’ve got Migalots auto box etc sorted)
I’m about 30 miles from you, and still have all of the cambelt tools for these cars :y
-
Hi James , I have ordered the Cam belt kit and water pump, and have messaged you direct with my contact details. Thanks
-
Thanks, got it. Let me know when the parts arrive :y

whats the theory on doing the water pump at the same time as obviously its nothing to do with a cambelt change.wasnt it mentioned on here by someone that decent pumps are now harder toget and best leaving a working pump alone until required ?
whats your current thinking on this .

How would you know when a water pump was required? When it seized and threw the cambelt?

A water pump would have to be really crap not to last for the suggested cambelt interval, which is 40,000 on these old barges.

When the water pump is driven by the cam belt, it is categorically part of the job. If accessing the water pump is difficult, then replacing it while you've already dismantled the front the engine is sensible. Neither of those apply the V6 in Omegas. The advice was given when good quality pumps were so cheap that adding another 5 minutes and <£20 to the bill made a lot of sense.
Now that the pumps are a lot more expensive and have proved not to be a common failure, replacing them just because is much harder to justify. For me, a basic inspection(does it leak, look really crusty, and are the bearings smooth and quiet) once the belts and covers are off would drive the decision.
A better thing to consider while you're in there is the front crankshaft oil seal. It is a cheap part, and changing it requires removal of the timing belt and lower pulley. And V6s are notorious leakers of oil.

agree with all above.
my pump was changed when i got the car because it was leaking .otherwise its only got 2 failure modes (leaking or failed,failing bearings) maybee impellor failure on some pumps too ?.
pumps are easy enough on these its the thermostat thats over complicated.!
and yes the front oil seal. mind you mine was a tight sod to get off.6' scaffold bar wouldnt move it so cut bolt head off !

Personally I’ve had a lot of success with Circoli pumps which are about £30 from ECP
I don’t change the lower oil seal as a matter of course though. They rarely leak, if the car has been serviced reasonably well. :y

While my car is in bits, as it was last week, I get everything changed.
