Newbie to this site. Looks like I have water in the oil (grey and thin). Some help in determining the cause would be appreciated. Head gasket? Cracked block? Plan on draining and refill/filter. Should I flush w/ something?

Thanks

Hi and Welcome to FTE!

Yes it could be either crack or head gasket.

Can you give us a little more info? Has the truck been driven regularly lately or has it been sitting? Does it run ok? Have you done a compression test on it? Have you hooked a vacuum gauge up to it? What were the results of these?
