1990 Integra LS, there is oil in the radiator, and i saw bubbles in the coolant when i started the car without a radiator cap on.

Otherwise the car runs PERFECT, no smoke, idles fine, never overheats (even in this HORRID 100+ degree weather)...

anybody else have an experience similar to this?

think i should change the headgasket to be on the safe side?
Or possibly just flush the radiator and see if the oil comes back

i bought the car this way... didnt pay that much so im not too worried

 

Oily appearing coolant can sometimes be caused by people putting "stop leak" into the system. The bubbles are more worrisome... However, if it runs fine, doesn't over heat... I would just watch your coolant and oil levels and drive it.

 

Bubble could be just air bubbles in the system. Only culprit would be headgaske though. Id drain the system and flush it with water and replace with new coolent. Then if oil re-appears Id bet on your headgasket leaking.

 

thanks for the help
