I just couldnt make power with it. Just couldnt control knock noise in 2 and 4. Engine was audible noisy when cold. had rod knock sounds. Horrible lifter noises cold and hot. And was burning oil. And I mean burning some serious oil. I has just changed the oil. And after about 1/3rd tank fuel it used about 1.5 quarts oil. So decision was made to tear engine down for freshening up. And holly hell the things I found wrong with her. glad I didnt try to pushing it any harder. 2 and 4 are leaking oil at guides. 4 getting hella lot of oil. either that or horrible eth distribution. But I am leaning toward oil coming from head in that cylinder. no 2 cylinder missing 1/3 of its threads. (poor plug cooling) And last but not least rod bearing wiped out from excessive hot start issues I had with the ID1000s that were in the car last year. on the good side pistons look amazing. No signs of knock whatsoever. I had Zero blow by and seemingly perfect ring seal. and excellent head gasket seal as well. so good news is so far block doesnt have to come out. just needs fresh bearings. just need to build a nice cylinder head for it.
