Hi all
Driving around town i noticed the temp gage went up to 90, never usually goes this high. Was just driving normally, not excessive acceleration or anything.
Got home, without thinking i took the lid off water/coolant tank, made a pretty fountain lol so didnt get chance to see if water was running low. Had leaks from cooling system a while back, i put in some radweld and it sorted it.
Also the oil filler cap has alot of creamy stuff under it. about a month ago before a long journey i noticed some, cleared most of it out and forgot about it. maybe the two are linked?
Not planning on keeping this car much longer, absolute nightmare, conned by the ******* who sold me it when i was desperate for new car. also costs to much to run really and has a variety of other problems aswell.

ALL THE EX PLOD ONES IVE HAD RUN A BIT WARMER THAN MOST MY CURRENT ONE SITS AT 85-90.C IN TRAFFIC WILL GO TO 100.C BEFORE FANS CUT IN. THING THEY RUN HOTTER STAT TO KEEP THEM TOASTEY INSIDE. OMEGAS DONT LIKE SHORT RUNS THAT COULD BE THE CAUSE OF THE SMALL AMOUNT OF GUNGE ON THE FILLER CAP.

Sounds reasonably normal for around town. That's also likely why you have the mayo build up.
Worth an oil change and breather clean followed by a good blast - you'll probably find its clear then.
-
You mention you added radweld.... it's quite likely clogged something up, causing the overheating.. evil stuff...........

As James says, I suspect the radweld use as the temp is higher than I would anticipate. Police or private, the temp should be the same.
I suggest that you refill and flush, perhaps with an additive (radflush by Holts?) then refill and see whats what, especially the 'had leaks before so used radweld' bit.... ;)
Creamy muck under the oil cap will probably be short runs whereby the engine oil does not get fully warm and that the filler sits higher than the engine, thus cooled by the surrounding air.
Clean it and see what happens after a reasonable run. :y

Absoloutely agree with B - only thing further I'd add is that I have had great results from forte cooling system flush...

just to add a note, as big griffin said (as i supplied his car!), a lot of the met police ones did come in running much hotter than normal, no explanation for this, maybe they used different stats?

Probably 'cos it had the 'dangle berries' kicked out of it from new...... ;D
Been there, done that.... ;) :y

i've used rad weld as a last resort with no issues, worked well in fact, thats not to say its risk free, only use one bottle per system.
Dont think i would worry tooooo much unless it went into the red to be honest.
Mayo in the filler cap is quite normal for anything approaching short journeys, if you want further assurance you can remove the filler cap then un plug
the filler neck by lifting the tab off the cam cover bolt and twisting it to remove as you would the filler cap. The cap can then be plugged into the cam cover directly. Run it like so and check the cap again after your normal journey. It will be clear of mayo.
The neck is only there to aid filling on the rear wheel drive v6 omega. On the front wheel drive v6 vectra the same engine is mounted sdeways on making filling the oil easier so no neck is required. Its the neck running in colder air that causes the mayo.
However the cap is a good gauge of the condition of the breather system, as the same principal applies. There is a guide on cleaning the bbreathers in maintenance section, if it blocks up piston blow by pressure will have no release and blows the cam cover seals, in turn oil leaks into the plug wells eventually causing missfires.
Dont panic, its the same on most other petrol engines but they dont have the filler neck to give a guide to the state of the breathers.
