V6 oil Questions

[madsav]

Long story short, there is oil in the radiator
Compression test on the motor comes up at 180-psi per cyl
Oil in the motor looks to be black ...oil cap looks slightly milky

Drained the oil poped gtx2 and new filter in now the oil looks REALLY milky
Any advice?

Car seems to run 100% perfect not a miss or any sounds out of normal

did they do a proper leak down test or just a quick compression test?
you could have a split in the head gasket, or even a cracked water jacket
and if there is water in you oil i wouldn't be driving it, the oil will no longer be doing it's job and the internals wont be getting the lubrication they need

What about the internal transmission cooler in the radiator?

[madsav]

it running on external core tranny cooler,
did a leak down test and seems to be good holding pressure
before i changed the oil ,the oil was black and the car haddent been started in about a week
just wondering if it is possable that the sump might of had abit of water and its just smashed it all together?

Could be a leaking inlet manifold gasket. Check the bolts to see if they are loose.

Bingo. These things are known for degraded intake manifold gaskets. That will be your issue

its had a new ACL inlet gasket kit for about a week so far , think it could be the new gasket?

im guessing cracked/blown or rooted head gasket mate id say get ur heads replaced go to the wreckers and pick 1 up for cheap just make sure its for ur car i had the same problem when i first baught my car had to replace the head coz it was the same only to find out 2 months later i blew the engine driving it thinking it was nuthing to worry about bro if i were u dont drive it and get a second hand head gasket the service it again and im sure ull be ok

Cheers mate thanks

Yes it could still be the new gasket. Did you install it with a coat of sealant or hylomar spray ? Did you put the blobs of sealant on the ends of block ? Like you me and many others the ACL gasket is a shitty plastic one the same as what was in there before. Has caused issues to millions of gm cars around the world this stupid gasket. Anyway, it may not have seated properly and also only run water in engine for first 100 k's.

Hi mate yea i thought that might have been the case so i riped everything apart again and checked to make sure it was alla sealing 100% everything looks to be good, i was maily focused on sealing where the water jackets run
im going to drop the oil out of it again today and drop some new stuff in to see if that might be abit better
sorta hopign it was just water in the sump that didnt drain when i first drained it
