Unhappy 95 Chevy SS oil in coolant

This just happened, so I have not yet had time to run a compression test. Engine is not running rough!

I am new to the SS Chevy, so I was wondering if anyone has any experience with oil in the coolant-it is engine oil- not transmission fluid.
1995 Chevy Impala SS RWD.

? is there any other source for engine oil to get into the coolant other than a
blown head gasket?

Also if anyone has directions to a site specific to SS Chevy Impalas?

Cheers, Erunner

Before you get yourself all in a dither, don't you think the first step would be to at least determine what the foriegn substance in the coolant is? Then the next step might be to tell us what kind of "SS Chevy" you're refering to. Cobalt, Silverado, FWD Impala, RWD Impala, etc. Get the idea?

Probably not.

Updated the original query per your comments-thanks.

95 Impala SS, RWD, auto, 5.7L MPFI engine, with oil and transmission coolers in radiator, plus additional tranny cooler.

I put 40 lbs of pressure in the oil cooler with no apparent leaks.
Definately engine oil in coolant.
Running compression test this morning.

Any thoughts on other sources of oil in coolant?

Cheers, Bill

vwhobo doesn't believe in compression tests, but let us know how that turns out.

If your oil cooler isn't leaking then i would definitely lean towards a head gasket, however it may not always show up in a compression test. If it does, great, but if you get the same compression on all cylinders don't rule it out. Is there no sign of moisture in the oil?

Hey douche bag. Instead of casting aspersions and telling downright lies about people, why don't you go back to work and sell someone the wrong parts after cleaning the toilet.

YOU re-worded his description to make it sound like he didnt:This just happened, so I have not yet had time to run a compression test. Engine is not running rough!

Umm.. Hobo was right actually, did you even read the guys second post? or even notice that his first post was edited atleast a day AFTER Hobo said that? He didn't have 'Impala' anywhere in there but has since changed it...

Edited original post- yes I did per hobo's first post

Thanks all. Working my way through the situation.

To be safe, I drained the oilpan- no water in oil.
Plugs out and ready to start compression test.
Missed the noon deadline on the radiator shop- so will have to wait for Monday on that. But will run pressure test on tranny oil cooler just in case, since I have the time.
Cheers, Bill

Well now, how does it feel to publicly display that you are a COMPLETE IDIOT? Even the gentleman who created the first post seems to think he forgot the information and had to edit it in. Have you ever heard the words STFU newb? I bet you have, many times. Go crawl back under your rock.

Off to radiator shop tomorrow.

Compression test was sound.
1,5,7 4,6,8 @ 225 lbs.
2, 3 @ 215 lbs. just a 4% variation.
Nothing abnormal on plugs- like 8 peas in a pod.
Pulled radiator- excellent shape. Off to radiator shop tomorrow morning for test of radiator, oil cooler and transmission cooler.

Cheers.

Thumbs up Oil cooler was cracked.

Radiator shop checked it out: oil cooler cracked and new radiator obtained.
Sorry for the delayed response- been out of touch for a time.

Quite a mess getting the oil out of the engine and lines.
And wouldn't ya know it- when we installed the radiator, it is the wrong one- oil cooler couplings are the wrong size. Back to the shop tomorrow morning. First time I have ever had a problem with them.
At least we didn't have to tear the heads down.
Cheers.
