So I have a 2.7 4x4 4runner and my mpgs are a little on the low side. Its kind of a wallowing pig in mud compared to the 3.4 anyway but on to my thoughts.

My tires measure 31.9in so those are well over the stock 30?(not sure but I have a base model). They also stick out from the side of the truck 1.5in so that doesn't help either.

I found the bigger problem tonight when I checked my valves. The picture tells all bit intakes are supposed to be .006-.010 and exhausts are .010-.014. Here are mine.


So x's cost me money.

I don't think I have toasted any valves but is there a way to tell? The valve cover had some toasted oil near cyl #4 but everything else is a nice golden brown. I will have pics tomorrow.
