Ok so lately i have had a weird noise becoming more prevalent on my engine. From underneath it sounds like its toward the rear and from above it sounds like its on the drivers side. The engine has more a rougher idle than it used to....i put stage 2 jammer nozzles in like 3k ago. There is some blow by coming out of the tube but not terrible. When the engine is off i pulled the dipstick and blowby comes out of there? Whats going on? Seems to run fine and have great power but its idle has been changing and so has this noise. I'm a little worried about it could you guys help, i should be able to keep driving it shouldn't i? I can't really describe the noise other than it sounds like a slight buzzing sound...idk...lol.
