guys

sorry didnt see any thread on this

coolant puking out snot as per video. my engine is running (1986 NA 944). coolant is blue and all clear, then after the burp there's white goo floating

any thoughts? i was thinking maybe headgasket, oil cooler.

I would do the oil cooler first then look at head gasket

I would do a pressure check on the coolant system first. If it won’t hold pressure, then you definitely have a problem. What does the dipstick look like? More milkshake/white goo? Don’t run the engine lest you trash the bearings. Drain the oil and check it for water/ coolant. Then go to the ORPV/ oil filter assembly and change all the parts out. You may want to check for exhaust in the coolant as well… you can get a rental kit to do this from Advance or AutoZone. Might save a head pull with all of it’s associated terrors and costs.HTH some.

So:
- cylinder compression test was ok
-test for combustion gases was ok
-spark plugs are ok
-no loss of power while driving
-no milkshake in engine oil
-no white smoke from exhaust

seems like oil cooler issue. ordered gasket set and will change engine oil as well as coolant at the same time. Car parked to prevent further damage

will keep you'll updated on next steps/findings

cheers

Puking coolant can be a bad pressure cap but I have mostly seen it after shutdown.

An update:
-oil cooler removed
-O-rings perished completely
-Plenty of muck
-You can see the point where oil/coolant mixing

Going to have it cleaned and new gaskets/O-rings installed
