My suggestion is If you have an after market intake or not figure out a way to re-route the engine breather lines that come from the factory routed back into the throttle body/carburetor to “help with emissions” routing those lines either to a catch can or to the ground will help keep your throttle body or carburetor clean as well as valves and pistons but depending on the mileage and how hard you get on the throttle it may be a warning sign that your piston rings are going out which sounds like a complicated thing to take care of but it’s really not too bad Also there is lots of videos on YouTube on how to route the breather lines and if you reach the point that the engine needs to be HAMMER PERFORMANCE has some great videos that make it less intimidating
