FIFY, lol

I am now facing a leaking head gasket due to PO's ignorance and negligence.

The correct 4 hole injectors for my Renix, OEM t-Stat, and everything tested and adjusted correctly. Also my "highway" is just that. Ether I bump around here hoping to see 16, or I'm on a road trip where it is pretty much all highway. Hwy 101 does have hills and curvy, slow sections, but just a couple places of stop and go. (Eureka and Willits).

I doubt the Castrol 30W is helping, except that it runs like it was young.

I seem to be getting 16-19 mpg around town, Depending on my driving of-course and 21-24 on hwy.. I have about 3K on new motor now and climbing...

When I got the heep she had 170K on the clock along with a blown head gasket, this was due to PO neglecting it.. The water pump was so bad it had no fins at all, Had no chance to stay cool...
