water in oil! HELP!
 

I noticed some oil on the dipstick was white,
I was wondering how to determine were it is comming from.
this is my first blazer btw. so any help would be great.
its my daily and its parked until i fix the problem.

First drain the oil right away, if it sits in there to long it will eat your bearings. The obvious thought is you have a blown head gasket, so that would be the first thing to test for. You can do a compression test or you can go rent the kit that tells you if you have exhaust gasses in the radiator fluid. But that might not give you a result if your HG is only broken between a oil passage and a coolant passage.

Is there oil floating in your radiator? If no, then its intake or head gasket. If yes its the radiator broken internally. If no, remove intake. If coolant is in below the intake, this is your leak. If theres no coolant here you are pulling heads... Sorry

If you end up pulling the lower intake be very careful about cleaning everything. Make 100% sure nothing falls in. Time and time again i hear of 4.3's spinning a bearing after someone changes a HG or the lower intake manifold gasket because crap gets in and stops the oil pump. Just happened to my neighbor

Welcome
 

To the blazer night mare where not just the simple things go bad everything as well will also.Sounds like either a head or intake.If your head gaskets make sure you check the heads for cracks at a machine shop

and it is a blown head gasket.. :( found alot of oil on the outside of the block, i cranked it up to run for a second and it started leaking again.
starting to think now would be a good time for vortec heads and injection..
