it is a red top, its still sitting in my old s13, well its currently at the mechanics and i'm pretty damn sure its the headgasket, my dad just wants to make sure so we left it at his friends shop to test it. i would dig in, its just that i'm renting right now and i don't have a garage to work on and driveway is out of the question because the home owners association will flame me with fines and i'll die... and i'd be doing all this for the first time, i actually want to do it now that i think of it but i'm going to peru for 9 months some time at the end of this month as a missionary so i cant, and if it needs head work i don't know how to go about all that stuff, and my dad couldn't do it cuz he's going back to school, oh boy complicated. he wants to sell the sr and everything on my swap and do an rb25 for me while i'm gone. I DO NOT OBJECT! =)
