Stupid mistake

The car has 182K then I changed my motor oil to Mobile1 now Radiator coolant become milk shake – now I don’t think my head gasket is bad, but synthetic oil somehow get to my cooling system.

Did I screw up the car, how do I fix this?

Thanks in Advance

 

milkshake in coolant = blown head gasket unless you poured oil directly into your radiator, which I doubt.

 

No I didn’t put oil in the Radiator

OK I just got my car back from EZ Lube – they changed engine oil no water founded any where. Then Flush the tranny no water founded, then Radiator oil all over it, now they flush the Rad using a machine.

Guy said drive around week or so, and then we’ll have to see if it’s a Head Gasket or anything else.

Other than H-gasket what else make this kind of problem?

Thanks

 

first of all, running the synthetic wasnt a mistake, all it has done is identify an already existing problem, if it is the headgasket (which it most likely sounds like it is), u may have caught it early before any serious damage was done

 

it was not a mistake using mobil 1 or JOE BLOW'S oil ,is not going to cause oil to get into the radiator,, no matter what weight or brand of oil you use,,

Do Not drive car around a week or so,, i cannot believe they said that ,,

there is an issue there.........have a shop do a leak down test,, do not wait for it to cause more, possably expensive problems

 

Thanks for the quick reply, yes I will get the leak down test, so far no oil coming to the Rad, drew around 200km today, no overheating, everything very smooth at the moment

 

yea thats usually how it happens, all is well until in an instant you got a thousand dollar problem, dont drive it anymore.

 

u can also remove the radiator cap and start the car, if the coolant is bubbling then its prolly the hg (unless u have a coolant leak somewhere else)

 

I'm confused on the milkshake thing...

Also, nice sig twisted

Yes I removed radiator cap and rev to 3000 rpm no bubbling – it just nicely flowing (I know what is look like – I saw this when my car was brand new) also if HG gone then I should have water in the Oil pan right?

I didn’t have any water in the oil pan and I don’t have coolant leak anywhere – I lift the car and check every where using 1500W Halogen Lamp

Anyhow I will not rule out Head Gasket

If I see more Milky coolant then I am going to take Engine Head off and change the Gasket. (I never done these types of serious jobs (except timing belt) – but if someone know how – please give me some info on HG replacement – yes I do have Helms Manual but Hands on always better)

Take your coffee mug and put some Engine Coolant then add half cup of engine oil – you will see Milkshake (and that’s what I had in my Radiator this morning
