96 blazer water in oil

[pizon6979]

Hello, I have a 96 blazer. I let my mom borrow it for a few months, when I got it back I started it cold and it began to ping or knock. sounds like lifters... so I pulled it into my shop and checked the oil... To my surprise it was like thick choc. milk (water in the oil) but it was also about 2-3 qts high on the dip stick. I put it up in the air and could see antifreeze "burnt" around the small exhaust leaks in the exhaust system. I drained the oil.. it took literally 3 hours for it to drain the "oil" was like grease. I could see the water in it. I was really surprised at how thick it was! I am guessing it is the intake gaskets, My question is... is it worth it? Not knowing how long its been like this, I don't know what Coolant will do to the inside of a motor? Any insight would be great! Thanks!!

pizon6979. if it was mine I guess i would fix it and cross my fingers the antifreeze didn't do too much damage, it was still running so that's a good sign. Honestly I've seen a little coolant in the oil ruin an engine but the lumina I bought and sold had the intake gasket leaking for three weeks before I got it cheap. I fixed the intake gasket leak and changed the oil twice and drove it for a month and it was fine.

I have seen water or coolant tear apart engine bearings. For the sake of cheap I would agree though. Fix the leak and change the oil afew times. It might survive.

After you fix the leak, pull all the spark plugs and put a gallon of regular diesel fuel in the crank case with a new cheap oil filter and turn the engine over with the starter. This will rinse any water out of the system. Do not try to start the engine with the diesel fuel in it. I did this until the oil light goes out numerous times. Then drain the diesel fuel out and put in some cheap oil and another new filter, put the spark plugs back in and start the engine. Run this for a day or so then change the oil again with another new filter. You should be fine.

Same situation here with intake gaskets.

Similar situation with truck and who knows when it happened.

I repaired the gaskets, changed the oil 2x in 1 week, and I'm 60,ooo miles since....
