Just got word back from the dealer. I’ve got a bad catalytic converter, possibly bad rear o2, and am leaking oil from cam carrier, oil pump, and valve cover (just replaced valve covers, not sure what I did wrong). Car is worth around $5000, has newish (30k) head gaskets and clutch. 100% rust free which is unheard of in Michigan, and is already lifted. Dealer wants $4700ish, which isn’t gonna happen. My main issue was getting very low mileage, I can live with the car eating some oil. Right now I’m thinking I’ll get a tsudo hi flow cat and an o2 sensor and o2 sensor fooler since the high flow will trip the p0420. This should clear out the MPG issue. It doesn’t seem like fixing those leak points is too hard (I’ve done clutch work and a lot of stuff on my brat, I’m comfortable doing anything besides engine/trans internals). Do you guys think it’s worth it? My only real hesitation is the engine has a nasty piston slap. Thanks, CL

I recently picked up a 96 legacy OB, 190k miles, fairly complete maintenance records to 175k, EJ22 motor, manual tranny. The engine makes a ton of noise, which I have gathered is normal, but the ticking / knocking is louder than most videos I have looked at. Initially i assumed lifter tick - replaced 1 qt oil with MMO, drove around. 500 miles later, not difference, if anything it is louder now... Bought some valve cover gaskets, plan to pull the lifters this weekend and see what they look like. Thought it might be a fuel injector, so i tried disconnecting each of the injectors on the driver side one at a time, no difference. symptoms: coming from driver side head (seemingly). louder from above the engine than if i crawl underneath. Tried to do some ghetto stethoscoping, but wasnt able to pinpoint it. Noise is present cold OR warm, idle or rev, coast or accelerate. Noise does get a little quieter when warm, but is still very much present. car drives fine, doesnt have all that much power, but I am not familiar enough with the ej22 to know if it is "normal" or not. No CEL or pending trouble codes in the computer (once i cleared the ones from my injector test ). video of engine running here: http://youtu.be/gzz8o9zHDYE I also looked at the sound clip, tick is every 2 engine revolutions, unfortunately most everything it could be happens once every 2 revs... it sounds too high pitch to be a rod knock, too deep to be lifter tick, too quiet under the engine to be a crank bearing, could be piston slap? I think piston slap would change more as it warms up, and it is never really cold here in CA, so the engine is never started all that cold. Plus I though piston slap would get quieter with a disconnected fuel injector? any suggestions would be appreciated! I love my sooby, but its a bit embarrassing to drive through downtown like this....
