I was meant weld it up after you removed it <img src="/forums/images/graemlins/lol.gif" alt="" />
Good one. I wonder why i never though of doing it the easy way... <img src="/forums/images/graemlins/rolleyes.gif" alt="" />
I had a 22re specialist look over the 22re 3 wks ago. Compression test was 220/220/175/220. Injector #1 & #4 was louder than the other ones (using a rod to listen to). We haven't yet figure out the oil burning issues but for gas mileage consumption, he's saying the injectors/fuel filter are in need of a cleaning when spring comes. I asked him about rebuilt but he said it wasnt needed yet, especially since the 22re has a head swap just over 100k ago.
Would it be my rings or valve seal on cyl 3?
Comp is good, especially for the mileage.
How much oil are you losing/month? Are you actually seeing it go out the exhaust, or just having to top off every so often. If it is just slowly disappearing, it could be a number/combo of small things, i.e, leaky valve seals, rear engine seal, oil pan seal/plug, and a little getting by #3 rings seeing how it is 45psi off from the others. Unless the oil loss is visual in the exhaust or you are having to put a quart in/week, I wouldn't worry about it.
Leaky injector seals could be the loss of fuel economy, though unless you can smell gas w/the hood up it is likely more from the exhaust leak.
I know you are concerned w/the repaired manifold studs, but I don't see another way of getting the exhaust leak fixed. Even if you were able to get the nut off, with the bad stud you still couldn't the flanges tight enough to seal up. I would pull the manifold and if the heli-coiled repaired studs don't work, just re-tap using a standard tap and stud, just a little bigger than the oem metric ones.
