Internal Oil Leak?
Posted 17 January 2013 - 03:59 PM
A month ago I noticed some stumbling when starting the car first thing in the morning. Replaced the spark plugs and wires. Front left plug showed white flakey buildup, the rest are fine.
Replacing plugs and wires didn't fix the problem, and now it's getting worse. The car is definitely running on 3 cylinders for about 30 seconds after I start it up after letting it sit for 4-8 hours. Today I finally drove it in the daylight and saw a puff of blue smoke in the rearview mirror when the 4th cylinder finally started firing. Once it starts firing, it runs like a champ. It's not burning enough oil to get me worried yet, but I guess I should start buying parts to fix this soon.
So I'm guessing I have an internal head gasket oil leak or a bad valve stem seal, and it leaks oil into the cylinder while it sits parked. Any thoughts from the gurus out there?

The valve stem seals may be the source of your oil burning. Try replacing the PCV valve.

Thanks for the tip on intake gaskets, I hadn't thought of that.

Also, my fuel mileage went way down from 30 to 26. I was chalking it up to cold temps, snow tires, and driving fast to the mountains with a full load of people, aka Ski Season.
