GM Crate Motor Purchase

I purchased a GM Performance 350 Crate Motor in December 2016, installed it into my 56 Chevy Pickup. We experienced a very wet winter/spring in the PNW and didn't get a chance to drive the truck very much until April and May timeframe. I started driving the truck as much as I could, weather permitting and at about 300 miles on the motor I noticed a big puff of blue smoke out of the passenger exhaust. Talking with my car buddies, alot of them said that maybe the rings have not seated yet. I continued to drive it on short trips and the problem didn't go away, it just got worse. Pulled the spark plugs and number 8 cylinder plug was very wet with oil and the motor started puffing out blue clouds of smoke about every 10-15 miles.
I called Summit and spoke with their tech folks and they told me that they couldn't help me, I had to call GM and talk with them about their warranty. The GM representative that I spoke with was helpful until he ask me what shop put in the motor and I told him that myself and two other friends that are very well experienced put the motor in the truck, well is tone changed and became very rude. He eventually gave me a case number and said take to any GM dealership and have them evaluate the problem.
I called 5 GM dealerships and only one would even talk to me about warranty work on a Crate Motor, the dealership is an hour from my home. I drove my truck to the dealer and they had the truck for two weeks before calling me to tell me that I needed to pick the truck up and pull the motor and bring it back to them in two weeks to work on the motor, they said it had excessive blow-by. I picked up the truck, pulled the motor and took it back two weeks later. Now a month has gone by and they have had it for 2 1/2 weeks until they finally got the engine apart to diagnose the problem. They called me and said the rings are bad and the gaps are to big. They told me they don't do engine work at the dealership and were sending it to a Machine shop for final diagnosis. I called today 7 weeks after this nightmare began and they finally got approval from GM to fix the problem. I called Summit Racing about this over a week ago and explained this situation to them, to see if they could call GM and apply some pressure to fixing this situation and the only thing that Summit did was to send me a SURVEY, really, great service after the sell. Very disappointed with GM Crate Motors, their warranty and Summit Racing. Dan Dearing Vancouver, WA.
