Then again probably not that common....as mines had a top end rebuild and probably wasn't done right

I got the coolant changed and flushed 2 weeks ago with red and all was fine, but the temp gauge has been up and down, never goes over 90 though. I looked at it in the bottle tonight and it looks grey/black, but when the guy I use did it, he had it idling for a good 15-20 mins and nothing happened but it's not red in the bottle now!

Thanks Mike......I didn't think there was but thought I'd ask, yea the temp never (well so far) goes over 90 so hopefully ok, I know that wasn't along time idling, he revved it quite a bit too to get thing circulating. I hope it just old coolant/oil in the bottle, I'll keep my eye on it

Sorry forgot to say, there's no mayo under the cap

Early signs of a oil cooler failing? the oil & coolant mix & oil gets into the cooling system.

Headgasket should be no problem, but the oil coolers have been known to have issues as mentioned already.

Time to cut my losses and get rid then, enoughs enough
