Alright open air box and bam oil. I need a part number for the ccv if some one could help me and whatever else I need. I will do a compression test to just to be safe. Thanks in advance

 

Welcome to the world of renix/blowby. Clean out all hoses/pcv, change the air filter - and learn to live with it. They all have it. Period. Minimizing it is key, and yes, the main thing you can do is replace the hoses/grommets from the VC and check all other hoses connected to the airbox.

Also, as per cruiser's tip(s) - you'll probably want to do the valve cover gasket, and while you have the cover off you should give it a good cleaning (air compressor helps), and also trim down the 2 metal drain tubes that are connected to the top of the inside of the cover. These tubes go down too far and suck up oil a bit too greedily. However, in his tip he suggested cutting the lines down as well as drilling holes at the top of them - mine actually already had holes (and they looked stock) but trimming them down by about 1/2 with an angle grinder and doing the gasket (felpro) seemed to help quite a bit. I still get oil in the airbox, but owell - it ain't gonna hurt anything, and it's minimized quite a bit.



I'm 99% sure the hose COMES with the grommet, but you can order a grommet to make sure - I now just have an extra grommet.
