Ok,the deal is my friend has a 91 integra with a stock b18a1 right. The car had its auto tranny replaced and ran for about a week and had 2 rockers or whatever you might call them,in the head break and drop a valve into a cylinder. Whoops. So he finds a b18b1 for 300 bucks,does the swap, car runs for a week and the same thing happens. i dont know what exactly they are called if they are still called rockers on a overhead cam but those keep breaking. 2 engines,same problem within weeks? what is causing this,i've heard maybe the way the tranny/torque converter is bolted,i've heard it could be the timing messed up,i've even heard it could be the ecu?! but anyways i need to know what is causing this problem? we want to get this car fixed but we are stumped. I know its a teg but you guys in the 4th gen site are always very helpful,thanks.
p.s.- just got a digital cam so i should be able to post pics of my 4th gen civic soon,late
