Crappy day.... how to break the seal on LIM gasket?

I've already had the coolant flushed once as per manufacturer recommendations. There is sludge in the overflow however it clotted up and stuck to the bottom. I took off the oil cap last night and looked in it with a flashlight. The oil around the rockers was cloudy and had a nice haze and sheen to it despite having 100 miles on it.

The vehicle has under 90k on it.

Yes but coolant contaminated with oil will find its way into the overflow as expanding coolant makes its way into the overflow. This is how I found out my LIM had failed in the Buick Century. Oil in the overflow and coolant in the oil. Taking off the radiator cap yields a white foamy substance on the top of the coolant.

I'd rather spend $40 and a few more hours making sure everything is right than need a new engine down the road.

for the last time its not oil, its impossible to have oil in your coolant. its dex sludge.

drive your car and stop over analyzing stuff.
 
It's very possible. It happened with the 3.1

If the head gasket is blown or the LIM isn't sealing correctly the oil and coolant will mix due to the water jacket and oil passages being close to each other.

There's no other explanation for sweet smelling oil and exhuast on top of coolant in the oil and vice versa.
 


If we're going to have a pissing match about it then I'll have the tech who is doing the recall work on my ignition tomorrow check the oil and coolant. If he thinks everything is ok I'll kiss your ass and whisper sweet nothings in your ear, otherwise I'll rub it in your damn face if he says the oil and coolant are cross contaminated.
 
punching out maverick!!!!!!!


due to you not understanding the inner workings of a engine. like talking to a god damn wall i tell ya.
 
Do a Google search and you'll see bad LIM gasket, bad head gasket and cracked block will cause coolant to mix with oil and vice versa. It's common knowledge these things will cause the two fluids to mix. But what do I know, I'm the noob around here with a 3.8 gpa in automotive technology courses whom also diagnoses and repairs his own vehicles. I've screwed up before but I always fix it.

just stop, every time you say that you sound dumber and dumber. oil can not get into the damn coolant, end of story for the last time.

coolant can get into the oil tho. your oil will be over filled, and be milky looking.

trans fluid can get in the coolant tho, ( i know i just blew your f ing mind) but thats not the case either.
 


so why is it not tranny fluid in the coolant? your killing me hammer.

google some engine cut away's or something, learn how a engine oils and cools.

then google dex coolant sludge.


im un subbing, your on your own pal.

Ok, I see this on both sides, it is very possible to have engine oil in the cooling system, but that usually indicates a crack in the block near where the oil pump is since it will end up with 60 psi of oil, but that would mean a crack on the block at a water jacket and oil passage.

I have seen this yes on a turbo Honda, now I am curious to see though how this all turns out. It was engine oil and not trans fluid, and there is a possibility that a head gasket might also be the cause, but again I cannot say that I have seen this on these cars and can't confirm whether the OP is actually seeing oil or not.

Although this has been a fun read.

Seeing as how the car never overheated, I doubt it's the head gasket. As I said before being called an idiot for knowing my **** I've seen a failed or improperly installed LIM Gasket in this case, cause oil to make its way into the coolant which will then make its way into the coolant reservoir as the coolant heats and expands, causing the system to build pressure and open the valve in the cap releasing coolant into the reservoir.

The Buick Century used ethylene glycol coolant and when the oil made its way into that reservoir, it caused the green coolant to turn brown along with an oil sheen on the top of the coolant. My reservoir as it sits now has the sheen along with dark and cloudy coolant despite being flushed less than 30k miles ago and completely topped off with new coolant.
 




The level in the reservoir last night was above the full line, now it's below the line. No external leaks that I can see.

If you look at the reservoir towards the right you can see a nice sheen consistent with oily water

you never saw this, cause it cant fvcking happen. please tell me in great detail how oil gets into the coolant. do f ing tell. im waiting.

ill add this tip. if you have oil in the coolant, the car no longer runs, cause it blew the fvck up.

no please take this BS to facebook or something.
