I've got a problem, my oil is milky when I changed it , I have been having problems bleeding the cooling system, I keep getting air in it , so the pump isn't circulating , I am getting bubbles in the overflow tank when the engine is running , is it the head gasket ?

No I don't have a pressure tester, its an aftermarket alba radiator (fairly new), Its constantly getting air in the cooling system. I'll bleed it and it will run cool , then I'll let it cool down and I'll have to repeat the process all over again, So my logic is telling me its the head gasket, plus the water in the oil is confirming that , other then that it runs great . thanks !!

Nope... Don't need to pull engine. Just the head. :)

Seriously its not hard. Download the service manual and should be able to do it in a few hours max.

I blew a head gasket on my grizzly 660, replaced it and it blew it right afterwards. I ended up taking my head and cylinder to my machine shop to have them surfaced because it was warped. Yes my was sleeved cas it was 5mm over but it was still needed. So i would try to check to make sure there are no problems there, it sucked taking it apart many times.
