Question Smoke coming out of the breather

This is probably a simple problem, but lately when I start up my engine ( I have a 258 6 cyl. btw), smoke comes out of the breather, it kind of varies depending on how how the engine is. Any solutions? I was told it was burning oil, but Im still not sure. All I know is that a few vacuum lines are kinked or missing, which is probably whats wrong. Thanks in advance for any help

Yes it is most likely blowing oil. How many miles are on your engine? Has it been rebuilt in the last 100,000 miles? Maybe some rings and/or gaskets are bad. For now, stay on top of the quantity and quality of the oil in it. Perhaps some Motor Honey might help, too (a $3 fix). Oh yeah, avoid driving by e-check stations

Yes, could be engine "blow-by" due to high miles. How many miles are on it? It is very common. Mind you, the motor is nowhere near rebuilding just because of that, just that you will go thru a little more oil, so check it often, carry some with you. It will make your engine oily, so you may want to wash the engine once in a while at the car wash.

I lived with blowby on my last CJ-7 for years before finally doing a performance 258 (Clifford Performance Products )

Hell, at one time, I had a complete burnt exhaust Valve, burnt off from the edge of the valve all the way in to the stem, in a V pattern. I had zero compression. Drove from RI to Pittsburgh, PA 90 MPH all the way no problem, and kept driving it for a year while I finally started building my performance 258. Then, when it was ready, I did the swap over a weekend, and was back on the road (ripping up pavement, this time) by Monday Morning! <img border="0" title="" alt="[Wink]" src="wink.gif" />

So, don't sweat it, if fixing your vaccuum lines doesn't do it (probably won't, unfortunately), your motor isn't anywhere near dying yet. Just needs to be fed some oil now and then, LOL.

Very hard to kill a 258!

Hey, no problem! The 258 is a die-hard motor. Good Luck with it!
