Lately I been noticing some powerloss once in a while. It just feels flat after 3k rpm and doesnt climb up like it used to. But sometimes it drives fine.
I also feel the engine sputtering in low RPMS, and sometimes I hear a pop from the exhaust which i never heard before.

Also, my oil comsumption is kind of high. 1qt per 700miles
I also found some oil leaking in my intake.
When the car was started, I took the dipstick out and noticed some smoke blowing out. Not a crazy amount but noticable

I havent got any CEL's
I have a testpipe and a Berk highflo cat
No smoke when i drive, sometimes greyish smoke when i hit vtec
bumper gets a lot of black soot

Any ideas what can be causing my problem?
Im worried of major issues

have a leakdown performed?

Sounds like a Piston Ring problem. Do a compression test followed by a wet compression test.

thats what i am afraid of. Will be getting the test done tomorrow

hoping maybe something like bad coils are causing issues

If your getting oil into your intake it could be something as simple as your PCV. This might also cause a vacuum pressure issue in the valve cover which could be pulling the smoke out when you pull the dipstick. A real bad PCV could cause high oil consumption and poor performance.

I took the PCV out, it was pretty oily, and i heard the rattle when i shook it so I assumed its good. Should I try replacing it still?

bgoetz

Yeah they are cheap

f20racer

just changed out the PCV valve

Old one was a aftermarket one, hope it helps
