Default Oil Consumption Problem Solved!

In a number of threads on this forum, I have mentioned that for years I have gone through a quart of oil every 1000 miles. It never bugged me, really--I just considered it like having an oil change within an oil change. Of course, I was a little put out at first because I remember some of my old VW Bugs using that much oil--but a modern engine? Why? No one really knew.

Anyway, I never had any oil leaks or oil burning issues, so I lived with it.

But a funny thing happened when I changed my PCV valve and its hose (the hose was cracked a little, so I replaced it too). After a month of driving since the new PCV valve, the PT no longer uses oil.

Hm? Oil consumption in PT's is a very common problem (for many PT's--not all). So if you're one of the "oil users", try replacing your PCV valve (with OEM, of course), and see if your oil consumption disappears also.

Neon filled up so fast it wasn't funny, took it off.
Not all liquid is oil; guess most is H2O

Well, I noticed when I changed the plugs and wires a while back, that the upper manifold gaskets and gasket area was oily. I didn't know where the oil came from, other than the PCV system. But I just put it all back together and all seemed well.

Then, about a month ago, I noticed a cracking at my PCV hose--where it attaches to the manifold. I figured it was time to replace the hose--and the PCV valve (74,000 miles). So I did.

Then as stated in the OP, I no longer had the oil consumption problem that I have had since about 50,000 miles ago. Obviously, the PCV valve was allowing, not only crankcase vapors, but also oil (too much oil) to escape into my upper manifold, which would, of course, be burnt in the combustion process.

And another thing: I have never had a drop of oil at the bottom of my air-cleaner box, as some posters have mentioned. So I never felt the need for a "catch can".

No, it's not a turbo. It's a 2003 Limited Edition. I could have gone with a turbo back in 2003, but the thought of having to buy premium gas just didn't sit well with me. I can't do wheelies, but I get around ....

Besides, turbos, to me, are like sticking your spurs into the sides of your horse. Something about them makes me think you're forcing the issue. I guess I have more patience out on the road. It's probably all those years of driving VW Bugs and Busses. After them, most any modern car seems like it has enough power to me. In fact, if it weren't for air-conditioning, I'd still be tinkering with a bus, I guess.

That's why you don't get any oil in the air box because you have a N/A.
Anyways, you should have bought a GT , it's only $2 more at the pump, because here is only 20c more a gallon. And I get better mpg than my wife's N/A.
