I have a 88 crx d16a6 turboed and just started noticing the vavle cover breather nipple smokes and under boost smokes even more and spits just a little oil y?

 

its call blow by

 

how do u fix it and can u explain blow by a little more. Just my first boosted car

 

the explosion blow by the gap between the piston and the cylinder.you can use a catch can to keep the spitting oil off your engine but only a engine rebuilt will fix it if it's to bad...take a compression test you will be fix on your engine health

 

big sign that your motor is going imo! could be wrong but it started happening to me and then I got rod knock

 

No, you have to much pressure in your motor from when you hit boost and your motor is not able to breath just from that one nipple. You will have to put a catchcan setup and weld bungs on your valve cover look up catchcan setups to see what I'm talking about. To the kids who said your motor is going to blow, not true, why do freshly built motors have catch can setups with 6 breathers? obviously they are not going to blow, its because of the extreme amount of pressure in the motor that needs relieved.
