Has anyone ever bought a GM OEM Crate Motor ? I have 1990 Chevy Silverado C \ 1500 5.7 TBI. Several places offer a replacement long block that is brand new, same spec's as the original. I bought my Truck new in Jan. 1990. It used over 2 quarts of oil between oil changes. I looked in my Service and Unit Repair Manuel's and noticed the small block V-8's did not come with valve stem seals on the exhaust valves. I contacted the dealer about the oil usage, he claimed GM's policy was it had to use over 4 quarts of oil between oil changes to be considered excessive usage. He had no answer about no valve stem seals on the exhaust valves. I had to have seals installed myself before the oil usage went down. I can't figure out why they were not installed at the factory. I now have almost 500 thousand miles on the motor and it is loose and I need to rebuild it or buy another Engine. The crate motor sounds like a good deal, 2000 bucks, free shipping and no core return. I need to find out if it has valve stem seals on the exhaust valves, or if it is like the original motor. Has anyone on the forum ever used the gm crate motor for 1988-1995 gm trucks? Thanks, Mike Duckworth.
