LIM Gaskets or Head Gaskets
Great bunch of information here, I searched for a good hour before I thought I could maybe get a touch of input.
I have an 02 blazer (4.3), 3 days ago I was checking my oil when I was getting gas, I noticed it was slightly higher and was a little diluted. I instantly knew a internal issue, drove it home, 4 miles and it has sat there since. (I have a brutal work schedule till Wed) so trying to get my info first before I start on the project.
SES light never came on.
Runs perfect still, nothing that I noticed.
Coolant was low (obviously its in the engine).
No external leaks noticeable (at least that I could see).
My feeling is it is probably the LIM gasket, which I will do both upper and lower. But how can I be sure that it is not the head gasket, I read they have very similar symptoms.? If a head gasket goes does it bring up another set of issues, like mis-fire or anything?
Thanks for any help, I will have a few days till my next day off to soak in some info!

is the oil milky? or smell like coolant

Yes, diluted, slightly off colored like coffee. Not milky yet, as I check all my fluids every gas up, so I think I caught is pretty early.

good thing you did and didn't cause damage
sounds like your head gaskets id wait for a 2nd opinion tho

Thanks for your input, however my understanding (which could be off)... is...
Head gaskets usually push compression gasses/oil into the cooling system (which in my case looks fine). Not coolant into the oil, but I am not a master wrench, any other input would be very helpful...

to check the head gaskets go to a store like autozone..or any place with rent a tool.
get the compression tester kit, its easy to do just a pita.
that will tell you if you have head issues.
