Blueprint warranty status Thanks for all the comments, I did follow the break in to the letter and no this is not my first rodeo. I did not tear the engine down before sending it back, didnt want to void the warranty. I am still thinking it was probably a cam lobe. All the plugs looked good except number six. Completely fouled out. My guess is that one of the valves in that cylinder are not opening. I also think zinc is not the cure all. Up until recently I never added anything to the oil expect STP for break in. Cheap chinese metal may have something to do with it. And yes this engine survived the intial break in. It wasnt until about 300 when it failed. Called them today and they received the engine yesterday. Said it could be up to 4-5 weeks before I get a replacement. If you guys have seen the couple pics I have posted you can see a have a car that I am very proud of and deserves to be shown off. It was built completely by me and my father in law in a small garage. Metal work, interior, paint, suspension, electronics everything. 4-5 weeks in the best part of the year to drive a car with no ac sucks. I worked my butt off to have it ready in time for spring and the guy on the phone today told me it takes 5 weeks to build a motor. My machine shop can do the machine work in a day and I can build one in less than 6 hours taking my time. I don't care to wait I wish I would have known that before I pulled it in my garage. Now I cant work on anything else and I don't have my car to drive. Garage is on a hill or I would push the darn thing out.
