Chances of all 4 losing compression and being about the same is not likely. That being said, those who dont have compression testers, who want a backyard check, do this: Disable ignition by unplugging coil pack. Crank engine for about 5 seconds straight (car wont .
I was going to do a compression check today, but got a little confused while reading the directions to do it in the Chilton manual I have. I've done compression checks on .
Low compression is more likely to be a valve problem, or worn piston rings or cylinder wall. Lower compression during a dynamic test could even be due to a slightly .

Planning to keep the EJ22 in for reliability and fun to see how far I can go with it. I drive a turbo 2005 LGT wagon now but I miss the NA sometimes Anyways onto the plans: Pistons: From my reasearch I have seen overbored OEM pistons, is this true and how much would they bump up compression? Cams: going to see how aggressive delta can make them.
Yes I would definitely keep an eye on that cylinder. Compression check is easy. Buy a compression gauge, then take all 4 plugs out and disconnect the coil power wire. Screw gauge into spark plug hole then crank it . EJ22 is 2.2l and EJ25 is 2.5l . the exhaust is different. Note that later EJ22's are rated at 142hp..so the head design is a plus, along with higher compression and other minor differences. You're welcome, Jay Storm. . the sniff is the backup test. You're welcome, Jay Storm. Save Share Reply Quote Like. Z. Hey fellas, my 95 ej22 that is in my 86 has ZERO compression on cylinders 2 and 4. I installed new head gaskets and valve seals. The timing belt seems to be installed properly, all notches lined up, 44 and 40.5 teeth! . but I think if that were the case none of the cylinders would have compression. I'm doing a leakdown test tomorrow, so I'll .

After doing your compression test, you will want to see compression of no less than 165 psi if your engine is a Phase 2 engine and no less than 160-165 psi if the engine is a Phase 1 engine. My interest in the test result is to spot a sticking valve which would show up as an anomalous cylinder and lead you to follow up with a leak-down test. The phase one ej22e's work well, because they had slightly lower compression than the phase 2. 9.5:1 and 9.7:1 respectively). the phase two ej22's used a thicker head gasket, nearly identicle to the wrx head gasket. No matter which engine you choose, phase 1 or 2, run a phase 2 head gasket. the USDM ej205 has 8.5:1 compression ratio.View and Download Subaru EJ22 repair manual online.

a leak down test could show where the compression is going to. to preform a leak down test you remove the spark plug. put an adpater into the spark plug thread. and hook up air to the adapter. make sure the valves are all closed on that cylinder. then where ever the air escapes from while airing up the cylinder. is where the problem is at. But it sounds like its time for a compression test just to make sure the engine is ok. On upright engines the oil would leak down past the valve stems (when the seals are shot) and would burn on startup. If a wet/dry compression test is good, its a simple problem with a complicated fix. nipper Just did a compression test on a 2001 Outback donor engine before I pull it out. I’m planning to do head gaskets, timing components, water pump, reseal it all, etc. while I have it out as I’d like to try to get 50,000 more miles (maybe more) after the swap. Right now it . Well I finally got the engine all together - ej22,ej22t internals, ej251 heads, ej251 intake. Now the ej22 worked fine before with matching ej22t heads, but I swapped out the heads for ej251. . No, I'm not positive on how to do it but, there's a compression test you can do without cranking the motor at all. I didn't even notice that you had .
Then you get the headgaskets for that block and match them up to your EJ22 heads and drill the coolant passages from the headgasket into the heads. Then you will need to carefully drill the two small holes through the headgasket for the exaust valve coolant port for the EJ22 heads. Bolt it all together with your EJ22 acceroies and drop it back in.
is the hoae test hard
A quick little breakdown and comparison of the heads off the turbo and naturally aspirated version of the EJ22 Subaru Engine! We look over the similarities .
1996+ EJ22's have a single port exhaust and will work if you ALSO grab the exhaust manifold with the engine. . Can't really check compression by turning via hand, need to get it up to a few hundred RPM to properly test compression. Compression graphs are a function of RPM, with compression increasing as RPM increases. . yes, definitely do-able. I've got a friend running the opposite in his impreza now, 22 block with 20 heads. but probably not ideal. compression depends on exactly what it is, and what headgasket you use. assuming it's a USDM EJ20, it has to be an EJ205 ('02-'05 WRX), which means the pistons are designed for ~7.7:1 compression. and typically speaking, heads .
what are good ej22t compression test #s?
Using the thicker composite 1.4 mm Phase 1 gasket (Phase 2 gasket is 0.8 mm MLS but coolant pattern does not match Phase I head) will lower the compression ratio by 0.7 point. So using the Phase 2 block with everything else Phase 1 will give a compression ratio of about 10.8 (if my assumption is right that the Phase 2 Ej22 has a 10.0:1 CR). Are you talking about non-turbo EJ22's? I'm going to assume you are. The big thing is going to be the compression ratio. With the stock compression ratio of 9.5 to 1, you won't be able to run a lot of boost. Most people that I've heard of boosting non-turbo subie engines only run between 5-7 psi of boost.Subaru EJ22 Tuning "All you need to know about tuning the Subaru EJ22 engine!"

EJ22, worth fixing separator plate/rear main seal without rebuilding engine? Normally Aspirated Powertrain . I figured I could have a shop compression test, if ok then pull the engine, swap the seals, do a t belt/WP, etc, fix any other rubber or leaks while its out and just drive it till it has problems then deal with it later as it comes. don't do a compression or leak down test. exhaust gas testing of the coolant is the preferred way to test *for this engine specifically*. i have seen some initial blown gaskets even pass this test but that is rare. . another option is an EJ22 swap - they are relatively inexpensive and a direct and easy swap for an EJ25. they are also way more . With that said, a compression test's numbers dont necessarily spell disaster, it is the spread of the numbers. Yours dont look to bad, both pistons on each side are pretty close. You will know it if a ringland lets go you will have 3 with . EJ25 ,EJ22,EJ20,EA82 . Wow. That seems pretty far off. No wonder you were having issuses. *subscribes . 1 or 2, other times double digits (under full boost). I had one severe account where it hit over 20.that's when the compression test came in. I think if these pistons were stock they (or at least one) of them would have been toast by now .

I have tried swapping the coil pack between 3 different coils, new spark plugs and new spark plug wires. I've also smoke tested the intake track, done a compression test which came back really good, and a leak down test as well that was good.
