As title suggests, I found coolant under driver side, right under the oil filter. I followed it up and found a bubbly leak right above cylinder 7 and just under the intake runner. Was curious if this is a valve cover gasket, intake gasket, or headgasket issue?
My 1990 Corvette coupe is stock with only 51,000 miles. Never had it overheat on me. I have noticed the 'Low Coolant' light came on a few days ago and I added some back to the resivuor but the light has stayed on since. Any ideas? Very dufficult to get a photo of the location, but its right under the intake runner where the valvecover and intake meet. the white residue seems to be related to the location. Here you can see what looks to be coolant pooling on top of the intake, leading to the leak.
If you have coolant pooling between the Valve covers and under the runners, that's an Intake leak if you look in the back corner on passenger side odds are you will find a Big Puddle there. If you are handy with a wrench you can do the repair yourself. It just requires taking top of the motor cleaning up very well and putting back together with gaskets it's a 5 hr billing repair at most repair shops may vary
Low Coolant light you need to add more water/coolant. on your 90, with engine cold, open the cap, add distilled water/coolant to near the top, let the engine warm up and notice when the thermostat opens and the level will quickly drop. Then add a little more to near the top and stop engine and put cap back on and done for now. check it frequently when cold, if you don't let the level go so low, then a quick top off the resevoir will be good enough. until it gets fixed.
