Can I remove the long part of the oil filler neck as on the 3.2's. Just had a quick go at seeing if it comes off, but being a bit on the cack handed side I didn't want break it if the 3.0 is different.....twist and tug,  just tug or leave it alone? tia.

From memory, I think its held down by one of the cam cover bolts. Need to slacken or remove the bolt then twist anti clockwise.

i would imagine its the same on all v6's ? just lift the locating tag and twist anticlockwise to remove .

Thanks...will take a closer look.

Carefully lift the tab that sits over a bolt head and twist out like the cap/3.0 one

Exactly this. It's a bayonet type fitting, same as the cap to filler neck.  The is a tang on the bottom with a hole that locates over the head of one of the cam cover bolts.

surely removing the filler neck makes adding oil so much more difficult!
I'm guessing the reason for removal is due to mayo forming on it ....  I never had a problem with mayo on my V6 when I had one

Its common on shittier oils, like Castrol, even on longer runs

The 3.2's have both been done yonks ago, but on the 3.0, I'm getting a few seconds of misfire on a cold start up, plus a couple of minutes of white smoke which is slow to dissipate plus a small amount of mayo in the filler neck. But just having just done a 500 mile round trip without issues, other than the coolant changing in colour to a sludgy brownish colour, also oil checks out clean,I'm thinking possibly head gasket??

beyond rare to get oil/coolant mix due to HG on Omega V6. Oil cooler, yes, that's oil in coolant (but not other way, generally)

[Mutha Jugs n Speed]

Ooer! didn't think about the oil cooler. This 3.0 is an early facelift circa 2000, did they fit the oil cooler upgrade to stainless?

[Doctor Gollum]

Unlikely unless previously done.

That engine was built around 20k ago by Daz, loadsa time and money went into it, but Daz never did build sheets etc so must presume the oil cooler was sound at the time of the work being done. Luckily if that was a worse case scenario, Rock Autos still keep them for the Catera at £300 a pop. But further investigation will find out what's really needed. Strangely enough, I had planned to park this car and one of the 3.2's up for the next six months, as there's not much point in taxing them for the winter, that's nearly £800 that pig face won't be able to give away
