PCV hose leaks oil - Pirate4x4.Com : 4x4 and Off-Road Forum

Toyota FJ40 · 10-13-2003, 11:47 AM

Io searched and couldn't find anything, but the problem is that my PCV hose leaks oil into my air filter. I have replaced the pcv valve, the gromit that it goes into and the hose. I have looked in the chiltons manual and couldn't find anything,I also have adjusted teh valves already. Any suggestions, Ideas?

Either the intake line side of the PCV is stopped up or the engine is wore and has blow-by.

Thanks, I'm assuming it is the blow by, since nothing in the intake side of the pcv is clogged. I was kind of afraid that it would be something like that. Is there any semi-cheap repair or would only a rebuild fix it?

About the only thing you can do is put an inline fuel filter in and dump the oil out often, this way it won't get to the air filter element.

Not sure of your set up but on a F,2F and 3F the PCV is past the airfilter. The air filter does not need to filter it as it is "clean" air that is just full of oil/gas vapor. How do you have it run?

I had a J**p that had mad blow by. I just put a really long hose on with an nice "S" bend in it. When I got to work, I uncoiled the snake and drained the oil back in. I found a trick chrome breather to stick in the end as well.
