i plan on doing it right with machining etc. i have heard cooling is an 
issue with a large engine, but i thought 1776 would be on the low end of 
what would be considered large.

i wanted a counter weightedcrank and ported heads, but what is a case saver?

it is hard to keep track of my progress for this problem because the car 
runs and drives fine. the only way to do it is to take it to an emission 
test center and pay a fee. i do have an appointment with a local porche shop 
(high labor, but they are the only ones in the area that know the fuel 
injection system) to see if they can figure it out. i have been trying to 
figure it out as well, to hopefully save the money i will be giving the 
porsche shop. maybe i should just take it in and let them find the problem.

i mainly want to rebuild the engine for peace of mind, to stop some oil 
leaks and to stop the burning oil.
