My 86.5 n/a is acting weird and im stumped. Today, i was burping the coolant system and a strange thing happened. The was running great with the temp gauge reading under 1/2 way and then burp! The rad cap was off and all looked alright. Then, i rev`d the motor to 1000 rpms to try to get the coolant to flow faster and then the coolant turned milky brown with a foamy look. At first i shut the car off, and then shouted "Damn a BHG!" I just walked away and went for a walk. I came back and started to survey the damage. No milk in the oil cap, raditor, overflow and no antifreez in oil in oil pan. Then, i started it again with new fluids and nothing wrong. Just for kicks i did a comp test and the average number is 195psi! Please help im comfused! CLIFF NOTES: burping coolant system and coolant turned brown and then went away. Compression test is too high for some reason, avg 195psi. Sorry for my long post, just trying to thougho. Thanx and have a great day. Shelby
