Maybe valve seals?
I've searched and searched and wanted to ask what you all thought about this:
My car smokes white-bluish on startup probably 75% of the time. When at low RPMs, the car sounds like it's ticking. And worst of all, I used to get about 25-30 mpg and now I'm getting 15 to 20. Could it be the valve seals? I've recently done plugs, fuel filter, and pcv valve.
Any ideas?
Thanks
