2000 Malibu and butterscotch pudding oil please

[dustystrucktoo]

My house mate has a 2000 Chevy Malibu with the 3100 engine.  She has been complaining of losing coolant and I thought it was the patch job that I did on her radiator.  On Sunday I took a look to see where her oil level was.  There was a high level of butterscotch colored something on the dipstick.  I figured that her head gaskets went bad and I told her I could have it taken core of in a week, starting on Monday.  It has rained 3 days of this week.
I took the top side off and the heads looked fine, but the intake was a mess.  Her engine requires the use of Dex-Cool, which is Orange.  The block has been drained, filled with Kerosene and drained.  New head gaskets are torqued on at 33 lbs lus 90 degrees and a smidge.  Should have been 36 I just found out.
Any ways, tomorrow I should have the engine back together, remembering now that I scraped off the block/intake mating surface and didn't peel off a rubber gasket.
You know of the project and it almost being complete, but the oil factor is the strangest part I have seen.  The Dex-Cool blended with the Red Line Oil, which ended up being an oily pudding. I didn't hear any knocking before this project started, and I am not surprised due to the oily pudding.  5 quarts were 8 or 9 quarts.  the Kerosene didn't do too much on thinning it out, but brake parts cleaner beat the heck out of it.. 
Cleaning the intake and the heads was simple by using some Aluminum jelly cleaner, a lot of Pine Sol, some carb choke cleaner, brake parts cleaner and Kerosene.  I will be throwing in some old synthetic and tinge of gasoline in the engine to help flush the engine out due to the Kerosene not doing much.  Just at idle speed and a tiny bit of gasoline, like a quart.  I think 1 to 2 minumtes will be a maximum of the effort. 
I won't blow up or destroy the bearings....  Right??

Woah! I have done the quart of gas thing. Super bad Idea. You would be alot better off buying a case of cheap motor oil, filling the engine, drive it or run it to get it good and hot, drain, and repeat until it comes out clean. When I did it, my engine smoked like a freight train and made all kinds of weird noises. Fortunately, I didnt damage anything (small block Chevy), but the 3100 wont be as forgiving. The tolerances are alot tighter. Just flushing it out with cheap motor oil, and maybe an engine flush, but I dont advise gasoline because of my past stupidity. 3100s are prone to heads cracking if they get hot, and I think the water pump is mounted in a place to where if it goes out, the coolant can get into the pan. I may be thinking about a different engine tho, its been a while. I have a 3100 now with a valvetrain knock that I need to tear into.(I hate these engines, and the cars they come in) Good luck with yours.

Yep upper intake gaskets, so now that I read it all, are you just trying to get the ugly stuff out of the crankcase?

First off you're not using the correct cylinder head torque procedure. #1 torque the NEW head bolts (you can not re-use the old head bolts) to 44 lb ft in sequence. Then tighten all cylinder head bolts an additional 95 degrees in sequence.



The crank case cocktail is unecessary. A can of flush and 2 oil changes should do the trick.
