ok so i put a used EJ22 in my car and the engine i used had sat for probably 1-2 years. and now it has a missfire and one of the valves is like stuck and just sits there going tick tick tick.....also im wondering is there anyway to check the oil pressure????


Thanks
Ben

Change the plugs and wires or use known good ones. Check the cam and crank sensors plugged in and mounted. May need to check timing belt marks aligned. Add sea foam to the engine oil and run it for 20-30 mins. Change oil. That should clean it internally and free up the lifters.

ok so i already changed the plugs and wires and ive tested them by pulled the plugs off one at a time will the car was running and it dropped the idle about the same on each one.....so my next question is could a clogged fuel injector cause that??? because i know one was totally clog and i had to remove it to clean it....and when i went to run some fuel injector cleaner through it i just plugged of the incoming fuel line which then blew the fuel line off at the tank :evil: im not to happy....im pretty sure this is a stupid question but could a stuck lifter have anything to do with missfire??? also i ran some BG engine cleaner which didnt seem to help so what would be the next step for that lifter???

A few more things to try.

Rambling things off... thinking is there Air / Fuel / Spark.
My JDM injector rails had four plugged injectors probably from the accident it was in or from sitting in fuel for who knows how long. I unhooked the fuel line after the filter and turned the key on and had massive flow and reconectted. next removed the return fuel line and had plenty of return flow but no fuel squirting into the cylinders. When pulled from the rails they all had completetly plugged screens.
So you could have a more dirty or bad injectors. Your fuel is good? fuel filter is good? You should be able to blow through it.
I dont think a stuck hydraulic lifter would cause a misfire on these cars. Have you verified the timing marks?
The oil you changed after the bg flush didnt have metal in it...bearing metal?
I would get a compression test if timing or the injectors dont get you anywhere.
There are oil pressure gauges out there maybe Pep boys or Auto zone rents them. Probably have to rig up something onto the oil sender on top pf the block below the alternator/ps pump.
I had a used motor with major carboned up ringlands and one out of round cyl wall it would stumble at low rpms but run good revved up.
