Hi all, EJ251 shortblock, EJ25 D heads, STI gaskets I'm getting an unbalanced shake/hesitation from 1800-2500 rpm. I can't effectively accelerate until rpms are above 2500. Taking off from a stop, the car feels bogged down. Plugs, Wires are less than a year old. Fuel pump/filter/strainer within 6 months. Coil and ignition module are within spec according to an FSM that I read. There was a vacuum leak with the purge solenoid under the intake manifold. It was not operating. Before I found that, my STFT, and LTFT indicated (at idle) 3-10%, and 18-25% respectively. After plugging the vacuum line I have the numbers seen in the photo below. I just did a leak-down test. According to the gauges, I'm within 10% for each cylinder. ALTHOUGH, I do hear/feel air escaping through the intake, and the oil filler tube. I followed this for instructions: I have also done multiple compression tests. For cylinder #3 is 225 psi, the remaining cylinders are between 210 and 215 psi. Can one cylinder being higher than the rest cause an unbalancing/misfire/poor low-end acceleration? Even if the numbers are good, the fact that I have air coming through the oil filler tube and intake, does this suggest the motor is shot? Check my timing again? Is there any change in timing instructions when mating an EJ251 with 25D heads? The heads are closer together, and the bolt holes for the intake manifold needed to be filed down a bit in order to properly bolt it onto the long-block. I've done a smoke test in/around the intake/intake manifold/hoses etc, and don't come up with anything. Thanks for the help, Greg

Hello I need a little help. I'm working on rebuilding my EJ22t that come out of a 1992 Legacy. When I was putting on my new piston rings I noticed my compression ring was really loose. So I pulled out my calipers and measured my old rings. Turns out my oil scraper ring and my compression ring were the same thickness, so I'm assuming I need to get a set a rings that are 1.5mm 1.5mm 3mm. so I went online and all I been able to find are 1.2mm 1.5mm (3mm or 2.8mm) and the set that I all ready have is 1.2mm 1.5mm and 3mm, at this point I'm starting to feel like I'm going crazy. If you guys need pictures of anything just let me know and i will post them up. Thank you -
I see bits and pieces on other posts but can't find exactly what I need. I had my cylinder heads rebuild at the machine shop. I need a timing kit (looks like gates is the consensus here), rings and bearings, head gaskets (I can get wholesale price on Fel-pro at Napa), and a complete engine gasket set. The machine shop is quoting $600.00 and it's mostly JDM parts. There are so many cheap sets on Ebay that I don't know where to buy. Are Cometic any good. I have read yes and no. Any advice would be greatly appreciated. I am looking for stock performance with good reliability.
