Re: 199 MPG average? and oil usage

[speedyjeeper@xxxxxxxx]

Good idea on the heat riser..I haven't looked at it since I bought it and it sometimes seems to run hot too.  I'm not even sure it has one yet.  I've been driving the car more gingerly and the differeence is already apparant in the mpg.

I also performed the valve seal change this weekend on the 199, not a bad job to do..took a few casual hours to perform.  hope it fixes the prob.

thanks
