well i just got done with my desmog. Carb rebuild, new int and exh. mani, downpipe, tune up. get it running with a little skip. figure it was sitting a long time but after hours of dicking around i find the 3 and 4 cyl. are bone dead. 0 compression. after some test seems like its some bad valves. I can't believe this. totally sucks! So does anyone have suggestions on my tears down and build. I will need a good head gasket set if anyone knows one. I guess i will need a new mani gasket afte the $45 oem toyota one. And get this it didn't leak at all. well any tips would be great. thanks Also i bought this off the net and got burned by the previous owner.
