So I bought a JDM motor-got it-Re-Gasketed the whole thing!!!! My problem is that Im a newb to the Subaru thing and I did not replace the o-ring that keeps oil flow to lifters.. So a couple problems.- I used the entire intake manifold-injectors off the JDM motor but used my sensors of the running car.. Well I put the oil pump off the old motor cause it had good oil pressure along with all new o ring but as i was putting it in and this is hard to explain but there is a little copper ball and spring held in by a washer type thing right inside where the oil filter would seal-Well that popped out and I could not get it back on so i left it out and started the motor and no tick but as i drove a tick devoloped and got fairly bad.. But after I let it sit for awhile it will start right up and not tick??? Is this ball and spring the problem? or the o-ring or do i need a new oil pump.. Also the thing does not feel as fast as it used to be.. Before this motor the old ea82t had cracked heads-bad compression-TMIC-10lbs or boost and it was faster than my car now-Timing is set at 20 degrees btdc.. Any suggestions on what i can do to repair- Also under boost around 5000 rpms it startes breaking up a little bit.. What to look for... THanks

need some help come on!!!

hmm.. mechanics let me know if im wrong...(im a mech in training so to speak) I beleive that your little copper ball with spring is your oil filter bypass valve... it gennerely opens when pressure is really high in the filter... ex. cold start up.. or another ex. when your filter is 100000 miles old... better get that thing back in there!!! its not letting you get proper oil pressure... i think

 

as far as power concearns... I, We need more info on that... what do you mean it breaks up at 5000 rpm?? are you running 10 lbs right now... im confused on your situation a bit and what engine is this bad boy???82, 81 ,71 21.. just kidding

Its an ea82t.. Its currently at stock boost with a TMIC.. Okay if the info is right about the oil pump Ill change it ASAP..

The problem with it driving daily is that it has no torque.. It seems like I have to boost it to even get it to 35 mph.. Its so gutless.. Sometimes it will sputter around 5000 rpms but not all the time.. Most of the time its just feels gutless.. What can i look for!!

it's hard for me to say without looking at it but i'd replace that oil pump. i won't elaborate on what i think it does or consequences of not having because i really don't konw but i wouldn't mess with the oil supply.

 

as far as not running well....any check engine light? all the ignition stuff is new? hows is the turbo? any exhaust leaks before the turbo?
