Removed lower intake last night, it had coolant in oil, and its full of the milky mix, whats the best way to clean this??? before going back together

 

Change the oil. Drive it like normal for a day or so and then change it again.

 

thanks, its the 1st time ive had a 4.3 apart, didnt want to screw up, ive done all the car v6's this one had a mess like no other lol

 

With the drain plug out pour in a couple of quarts of oil to try to flush as much of the coolant out as you can. As swartlkk said change the oil & don't forget the filter. I would suggest changing it after a day of driving also but I would also suggest changing it again after a week or 2.

My son's car was loosing coolant very slowly and we could not find the leak. I sent an oil sample off for analysis. It only had 5% coolant in it but it was already causing excessive wear on the bearings from the amount of metals in the oil as reported on the analysis. The amount of coolant in the oil was so small that you could not see any froth or any other sign of coolant in the oil. So you can imagine what kind of damage a higher percentage of coolant in the oil can do. His car had a very small crack in the head.

 

got it wrapped up yesterday, LIM on the 4.3s arent that bad at all, didnt really run into probs either, but i will change the oil tomorow and again in a week or so, thanks for your help guys.

 

i added lucas oil stabilizer when i replaced the LIM gaskets with the oil, its been 3 days i still havent changed it, i plan on doing it tonight. i had a small tick on startup this am, its pretty cold here about 19 degrees. have u guys seen this???, i checked oil and coolant and both are good, have good heat and good oil pressure also.
