Anyway, I'll know on Thursday if the VSV fixes it. He's too booked up
tomorrow and since he charges me very little labor, if any, I have low

I just have to keep buying Toyotas since that's the vehicle he's most

a local community college, and it's not only for new mechanics but
continuing education classes for existing mechanics as well. My mechanic

ever stumped on a problem he can call someone from Toyota and get free

OEM parts so it wasn't too outrageous, though it was my own oil filter.
The oil pan gasket appears to be leaking a bit but the mechanic said to
forget about it, that they all do that eventually and it wasn't worth
replacing on a 14 year old car.
