I cruised cross country many times with 75mph or more, without any problem.
And those were old Vanagons without reconditioned engines, most all 2.1
engines.

Along similar lines...regarding the temp -

I've been hesitant to drive mine faster than 105Kmh (65mph) ...but my
wife asks me if we could go a little faster! Hmmmm

Yes.. back to the Bus - Therfore...If everything is running cool, say
300-350 then would it be OK to cruise at 110kmh (68mph)?  - assuming
road is basically flat. What about 115 kmh?(70mph) Or would I be
shortening the life span seriously / risk of over reving etc?

Does it all depend of the HP the engine is making and how well it's
running? I have oil cooler on it

Thanks for your help gang

Hi Nathan,

I'd say that extended running above 450 is to be avoided. Get off the
gas ASAP and it'll drop back to 450 or less and you'll be OK.

Running past 550 is going to reduce the life of the engine.

The valve seats often don't drop at high temp... they drop when the
engine cools down and the seats shrink. When my bus dropped the valve on
the way to JBB it ran fine all the way from Scarborough to Fort Erie,
but when I restarted it after our breakfast stop at the Duty Free I knew
immediately that the seat was FUBAR. I had not passed 425 at any time
that day.

There are lots of variations on this theme. As they say: Your Milage May
Vary.

Happy Trails,
