• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Yep, I'm a complete and total idiot for thinking my oil and coolant are mixing.

only the rear cover gasket failure would result in the oil into coolant (well a cracked timing cover would...)....at the same time it would allow tons of coolant into the oil resulting in a milkshake

oil would flow into the cooling system at running/startup. at shutdown the coolant would flow into the oil passages then to the pan.

you would have contamination both ways.
coolant in oil is a longer list of causes/pathways.

but since most rear cover leaks ive seen have been external...
 


I have to ask what exactly is so wrong in your life that you feel compelled to come on to a forum to potentially prove someone wrong. You look for advice and then when you don't like what you hear you go and try and find someone that will agree with you. There isn't really a point in doing this unless you're so insecure in some aspect of your life you need the justification and misplaced satisfaction of maybe "proving" someone incorrect here. It makes no sense.

Good luck on your repairs

Has more to do with ego, especially when you cuss me out and start name calling over a disagreement like a damn child.

Well I checked the O2 wire, it had come loose from the engine hoist bracket and was indeed touching the #6 spark plug wire, although it was the connector touching, not the actual wire.

I'll change the thermostat today but if I have bubbles in the oil again here in 300 more miles I'm putting a new gaskets in again. Not sure if it's normal or not but the level in my overflow has gone below the full line (I had it sitting 1/8 inch over the top of the full line) and the coolant level in the radiator went from at the top of the neck to at the bottom of the neck. No milkshake in the oil but I do have some missing.
 
That's the engine cover bracket btw. Hoist brackets are in the passenger back corner and driver front corner.

You are expecting a little much when you look at your coolant bottle that closely. Seems like the air is slowly coming out of the system. Again..if coolant was pushing into the oil, you would have a lot more.

Good call on this, I had commented in his other thread that I have seen oil in the cooling system, but never in a wbody, and can't confirm it personally in this case, good to know about the rear cover, and I would be intrigued now as well to see a case where there was a rear cover leak that did not leak out.
 


I'm found several 3800 rear covers where the gasket cracked and was allowing coolant to seep into the oil pan without affecting the adjacent oil passage
 
I put my LIM gaskets on backwards and got coolant in my supercharger. Super crappy. Cost me over 1,200 dollarydoos from Holden in Australia. Adam also pointed out because I didn't use RTV in the 4 corners of the LIM coolant also got into my rear differential on the GTP.
Guess ill just sell the GTP and go back to my '94 SVT Tempo...
 


Light hasn't come back on. Not out of the woods yet. Read on another forum someone had very similar issues after replacing the lim gasket on a 3400, except for the misfire. CEL came back on a week later with the same p0128.
 
3100 and 3400 are very different motors. Your LIM isn't the same as them and you aren't anywhere near as likely to get air bound trying to fill the system as them. Plus..on those ... someone didn't likely booger the tstat with needle nose pliers like you did.
 


I just found it odd that it took a week for any damage that may have occurred to throw a CEL. I grabbed it at the very top, were the pin for the thermostat slides up and down is located. I didn't crush it any, just left teeth indentations on the metal itself.

I also had my defrost on full blast last night, whenever I run the heat the temp gauge hovers at 1/4 for 20-30 minutes and finally settles short of the half way mark. Sounds like the thermostat may have been boogered before I yanked it out with pliers unless it's perfectly normal for the vehicle to run cold for a long period with coolant flowing through the heater core.
 
Well you see when you don't use a gasket for the thermostat it can lead to overheating. The coolant will escape and run down the engine block. At this point you will notice the car over heats a lot. That's because as your coolant ran down the engine block, it then leaked it's way into the oil pan. The oil pan gasket lets coolant in but not out. It's a special GM gasket. Very expensive.

The steering rack can be fixed easily. Lean over the engine , place both hands on the cowl just below the windshield. Have a buddy use a bottle or 2 of power steering fluid , apply liberally to a bag of dicks, and proceed to shove them up your ass one at a time until fixed
