nah, I don't loose brake fluid. I do however have a clogged CCV valve that causes the crankcase gases to cause pressure to push oil into the air filter which could get pulled into the throttle body and burn a minuscule amount of oil.

You should handle that... especially if you have to use higher than piss-water octane.

Basically, if you can't run on 87 octane, part of the reason could be b/c you're burning small amounts of contaminants in your intake due to a clogged/impassable PCV system.

For the few dollars it costs to diagnose/fix, you could get like 10% better mileage out of it. It's worth looking into.

Sort of on topic: One time I drove about 120 miles round trip in extreme cold. I had IAT showing on the Scangauge and it went as low as -6* F. The next day I noticed a small patch of white stuff on the bumper directly above my tailpipe. I couldn't identify what it was or why it was there, and thought it might be some sort of combustion byproduct. But I can't imagine what, or what the cold had to do with it.

Nah, the jeep runs on 87 octane.

and it doesn't use a PVC system, it uses 2 CCV valves on the valve cover, one is clogged (the famous cloggy rear one) and the other isn't. excessive pressure causes the front one to spit oil into the intake, which gets sucked slowly into the throttle body.

I could fix it if I had money. not at the moment. oil change first. then fix oil filter elbow leak, then spend the 30 bucks on the new valve.

Same boat, I'm probably going to take my car to the junkyard and get something more reliable, and safe, even if it doesn't get 40MPG in most any condition. I'm thinking a Subaru wagon across the street from me.

What do you drive?

Quite frankly, this jeep is probably one of the toughest things I've ever laid a wrench on. I could light a bomb and the engine would be ok. the only problems so far is old worn out rubber o-rings. and that valve that's clogged with soot.

It's a 1989 Honda Civic DX. Engine's been rebuilt about 30K ago or so, 5 speed, gutted, runs great w/ the CAI and 2.25" exhaust/header, gets about 40MPG on good weeks, and is a rolling POS.

I'd love to take the time to fix it up, but I don't have the money, and it's not really worth it. It's not enough to be considered a family car, and never will be, honestly. And we're expecting in June, so yeah. Time to get something a little more practical.

too bad you weren't nearby, my brother wants a Civic.

Christ · 12-15-2008, 11:32 PM

LOL... not this one. Seriously, I have a hard time thinking about selling it to people I don't like... and I like you, (so far) so I wouldn't wanna do that :P

I'm pretty sure I'm going to load it up with junk, take out all the useful bits, and send it down the road... its' gotten me plenty far for less than $1000 invested. I am thinking about using the proceeds to buy a van, to help prepare for the upcoming family addition.

DifferentPointofView · 12-16-2008, 12:20 AM

understandable. I wouldn't sell my Jeep unless I knew It would be taken care of, and in the event I wanted it back, I could easily buy it back from the person whom I've sold it to. If its someone who collects cars and works on them as a hobbie, Fine with me. As long as its not someone who doesn't know what oil changing means or doesn't know the difference between a metric and standard wrench.

Time to buy a van eh? make sure to get a squishy one! (those family vacations are hell after a 7 hour drive. imagine one of those 18 hour vacations *shudders*)

Too bad vans don't come in a manual tranny option these days. Hard to come by. Gonna do anything to the van for efficiency?
