I have a problem with my 99 chevy blazer. It is the mid-size (S-10?) and has a 4.3 liter V-6 engine (vortec). It has fairly high mileage (140,000) but the engine was replaced after only 60,000 miles, so actually it only has about 80,000 miles on this engine. The problem I am having is with the oil pressure.
Chevy Silverado 1500 - Silverado Gas Mileage - Repair History - Silverado Accessories - Buying A Chevy - About Us. 3 try to swap the spider injectors. I have a 2002 Silverado with the 6. GM Shift Cable. The Review is in and the 2004 Chevrolet Silverado SS 1500 is noticeably quicker than a 5. Killing Heydrich.
