EJ22T Rebuild Time

[cj91legss]

Could you post a picture of your water lines coming from the pump going up to the top of the block? I'm putting together a motor right now and it's been a long time since I've worked on an SOHC motor and I'm having an issue with one of the lines coming off the pump.

Well currently have the dohc head setup for it and waiting to finish up the assembly so no pics of current setup as have not quite finished it all. Also dont have any old pics of that line itself either.

[cj91legss]

I got it figured out. Accidentally grabbed my dohc lines.

Gotcha lol such a simple deal. Anyways another question I do have is since using the ej22t block and ej20g heads which spark plugs should I now run? Since going from sohc to dohc not sure how much it changes that. Thanks

[cj91legss]

Use 02 05 wrx plugs.

Just a heads up, i had an issue using the 20g/h cross over pipe because of the vent on the top of the block. I ended up using the 22t cross over pipe and plugging the vent. There' a pic somewhere in my build.

Thanks I will just use the 22t crossover and do the same thing than once I find your build.

Its cjs 92 prefaced legacy or something like that. Im starting another build for that car in a few months. Goin 02 03 bug eye swap, dash and all.

Sorry, It's not in my build thread. it's in the DOHC installation thread.

there ya go.

Well thought everything was all great and ready to go but guess not which is my luck. So need some info on what this would be and there are no CELS. Has like a misfire and when hit throttle a back fire. I am thinking lifter based on the sound I am hearing. Have tried swapping tps, iac and mass air flow for one. Have sprayed around manifold to double check for leaks none apparent. Have double checked all vacuum hoses were connected and going somewhere. Made sure was getting spark and all 4 are. Fuel can tell getting that as well as listened to the injectors which all are ticking. Now if that is the case in which I would have to pull the motor again, the head has been sitting for a few so would I need to do the manual bleed on it and get it setup or will ej22t ones work to replace. Unless any of you have suggestions on any ideas I could try would appreciate the help very much as drives me crazy, Upload a video in a second.

You can remove the valve cover and rocker assembly with the engine in the car. It may not be as easy as doing it on an engine stand, but is doable. I had to do this with my motor when I found out I had to put shims in due to the Delta cam.

The ej22t & ej22 lifters should all be the same if you have spares.

[92legacyawdturbo]

Thanks Josh. Decided to just man up and pull the thing so got it removed and do some work tomorrow and get this issue resolved. Just so I am correct if the lifter is ticking it would cause like a misfire right? Like it is stuck open or closed one way or another.

[Legacy777]

Not necessarily. The ticking is just an indication the valve clearance is not properly set. This can cause the valve to not open all the way or stay open as long as it should, but unless the lifter is completely toast I don't think it would cause a misfire without some other issue being present.

[92legacyawdturbo]

Alright so got the lifters that were dead replaced and seems to run somewhat better. Idling on its on but still seems to be off. I am wondering if the wrx spark plugs are the right ones or not for the block and could use any help on this. Still has slight misfire but not as bad. Heads were pressure tested and passed that part and all valves look good. I am either wondering A) fuel injectors not working proper B) spark plugs are not proper (wrx 02-05 plugs) or C) bad spark plug wire. If I could get some more input mainly on spark plug would appreciate any and all help at this point it in driving me crazy and just trying to get it to run proper. Thanks

I think your timing is off.

Pulled covers, verified timing and it is still correct for timing.

[92legacyawdturbo]

Replaced plugs and wires while I was at it to double check that. So new plugs and wires. Timing is good. Still sounds like a slight miss though so guess next step is the injectors on this. Just been trying to get it going and has been a pain in the rear. The EJ20G heads I had gotten sat for about 6 months or so, feeling it could be an injector but as I have spare sets around just requires my labor and time on it. Also it not misfiring just has a miss like a cylinder is not acting proper, it seems to be coming from the driver side. So should have done the lifters there to double check but already got motor pulled again, going to check driver side lifters and swap injectors. Than of course retime it and hopefully this is the last time the motor is out. The engine this time cranked up on its own and idled on its own just a slight miss and lifter tick driver side. So on to phase 3 of this deal lol.

[Legacy777]

Can you describe the issue in a little more detail. You say it's a miss, but not necessarily misfiring....they are the same thing. Any chance you can take a video once you get everything put back together?

[92legacyawdturbo]

Well got the motor back in and runs better after dealing with driver side lifters, still a misfire when you try to give it acceleration. All that's left is to figure out code 13 cam angle sensor and 31 throttle position sensor. Will post a vid again see if it works.

[92legacyawdturbo]

Also for crank pulley should I run the 2.2 one ? For cam sensor do you have to shim it or should it work right away? Looking for some more detail. You can hear it struggling to get above this and if you go higher it wants to misfire/backfire. Than you can see tach is bouncy as well. Not fully shown in this small video. Also so you know the cam sensor wiring harness was hacked by previous owner however did not have any issues before the swap.

[cj91legss]

Even tho the sensor worked before the swap, with hacked wiring, things just being moved around a bunch can tend to be bad. Especially sensors. Do you have a wrecking yard around you? Might just be a good idea to go snag another cam sensor and throttle body. N/A will work, they're the same.

That'll eliminate your engine codes, then you can reset your ecu and see if the problem is still there.

[92legacyawdturbo]

Well I have multiple cam sensors and throttle bodies. Gonna depin the ecu cam sensor and run the other one I have that has not been tampered with. Could try throttle body but I am sure the issue is for sure tps also as I unplugged tps while car running and no change at all.

[92legacyawdturbo]

Issues have been resolved. Ran used cam sensor from ecu to actual location and fixed it. Ran a used tps harness from location to tps and fixed it. Idles great no issues so far and get to try it out more tomorrow

[Legacy777]

Good deal. I was going to suggest taking care of the codes before proceeding with any further diagnostics.
