Looking for some feedback. I have a 2000 GTS. I have 300,000 miles on it and need a new clutch. Which brings me to my issue. Since I started driving in the City I have developed the 'Oil' problem. Going through a quart about every 600 miles. I am trying to decide between dropping a crate engine in it or rebuilding the existing engine and transmission. My mechanic prefers rebuilding since everything is original and would like to keep matching serial numbers to keep potential collector value. Price difference is around 2000. Though to quantify that he will be going through everything and fixing everything that needs done. I have one brake not working well, catalytic converter if necessary, syncro's failing on 4th and 5th on down shift, etc.
