Re: 98 isuzu trooper buring oil excessively

Hi Sword King! Your advice sounds inspring- I'm burning about a quart every 400 miles which would sound catastrophic if the car didn't seem to run so well and if so many others didn't report the same thing.

You're saying that it seems like the PCV valve is probably sucking oil vapor and droplets from the top of the head and valve cover, then burning it?And just to clarify, you're letting your valve cover simply "breath" by running a tube from it to some sort of container, then filtering "fresh" air heading into your intake manifold with a small rc filter?

If this is so, it would be an amazingly simple fix even for some improvement. Do I have the scenario correct? It sounds logical to me. Please let me know if I'm reading this right if you get a chance. Thanks!
