The VR6 engine is a hot one, we all know that, but I have a little concern over mine and what it's doing and if it's right or not.

On my run to Victoria it didn't miss a beat, cruise on 120 most of the way, at least as far as perceived running was going. BUT when checking the MFA the oil temp was always high, like 98, 100, 102. When I was slower that might be 96.

The water temp is... well the cluster was replaced and where the old one would sit bang on 90 all the time, the new one sits on about 70 (which I read as a faulty cluster). On this long run it would get up to maybe 80.

Note: Normall I drive about 9km each way each day, so barely enough to warm it up.

But back to the point, the oil temp seems a little high, even for consistent cruising at high speed, but is it? Is 120km/h for 9 hours going to result in high oil temps? (incidently the cruise to then up Macquire pass had the same effect so these temps seem to be common in my car)

Lastly, I do tend to burn a bit of oil... like a a few hundred mls on my 2,000km journey. On the oil burning point, the little pipe and valvy looking thing that rund from the crank case ventilation to the air intake was busted so has been replaced with straight pipe, same end result really, but maybe that little valvy thing held back some pressure and ventilated less, which would in turn burn less oil where my solution is more free flowing and potentially burns more oil. Providing this isn't detrimental to then engine I'm good with that, oil is cheap enough and I was taught to (and do) check the oil every time I put fuel in the tank so there is no issue of it running out.

All this seems sort of reasonable for a 10+ year old engine on a long drive, at least to me and considering everything seems to run spot on and the engine pulls hard, I haven't been too concerned. Still I thought it was worth the question.

So what sort of temps does eveyone else run??
