i just installed a f22b jdm SOHC in my 94 ex.it throws no code,it will start and idle but it seems to have some sort of misfire.the engine shakes alittle as if it running really sluggish.it willl rev. up but not with the normal snap like my last f22b1.im 90 % sure i have the t/b and b/s belt aligned correctly but thats the only thing i think it might be..if you have any suggestions id really appreciate it.thanks

do you mean jdm f22b DOHC ?

what ECU are you using?

 

no the SOHC,im using my poa.its the same as the f22b1 but it the jdm version.but it turns out that my compression is low in cyl. 2 and 3.i bought it from alljapaneseengines in florida and the guy says it needs time to break in and rings need to free up but hes probably just yanking my crank so my warranty runs out.he seems to think if i pour alittle oil in the cylinder it will free it up.ill try and see what it does but i dont think it makes a difference.i drove it and it hauls ass in the high rpms but the low rpms it just bla bla bla bla like its a miss fire but my ignition sytem is brand new and i had no problem with my last engine.but have you ever heard that oil frees up rings?thanks

 

i would do a leak down to find out if it's valves or the rings that are leaking...most likely you got a bad motor

 

you need to do a leak down test.

when you pour oil in the cylinder and it raises that means the motor is bad. sounds like the people you bought the motor from are shady.

also i have never heard of a jdm f22b SOHC,

 

definetly shady well put,but there trading me for another one,it sucks but rather pull it back out then get shafted for the price i paid.yeah everybody says they never heard of the F22B(JDM)SOHC but i swear to you there is.it says it on e block and the USDM says F22B1.its the same thing.the only differences are the tip of the fuel injector looks different and on the usdm there is a vacuum hose port thingy on the intake manifold for some solinoied sensor that isnt on the jdm,it takes a civic oil filter instead on an accord and F22B doesnt have the coolant sensor on the front coolant neck,which you have to switch over otherwise youll throw a code.other then that its preety much the same.thanks fotr your input though,this engine isnt worth my time trying to fix when this guy ay alljapaneseengines says hell swap it out for another one.thanks again.
