I have always built engines for my cars. However I have been working on my car for a year and wanted to drive it this year so to save time i bought a blueprint crate engine. I followed the manufacturer installations instructions to the letter. Primed engine, set timing and installed a previous tuned carb. Engine survived the 30 minute break in and the oil was crystal clean. Ran it with rotella 15w40 and Lucas break in. Changed it after 30 minutes just to be sure it was clean. Engine had some residual in it when I received it so I am confident it was dynoed. Changed oil after break in with the recommended rotella oil. I have been driving it every nice day to reach the 500 mile break in period because I was excited to get on it. 80lbs of pressure cold and 30 hot. Today I eclipsed the 300 mile mark and the engine has performed flawlessly. Starts great and runs cool and shows glimmers of excellence, no ticks, no bangs, no smoke. As soon as you start getting around 3000 rpms it wakes up. I havent taken it above 3500 because I was following the book for easy driving in the initial break in. However with every race car I have ever built it is balls to the wall on the first crank. Driving today on the way home from work and coming to a stop a heard a little rattle. Looked down to see 8lb of oil pressure on my dakota gauges tapped the gas and it popped back up. I wasnt too concerned because they are electronic gauges and I didnt trust them. Went straight home and hooked up a mechanical gauge. Sure enough 9lb of pressure on idle but it wasnt rattling anymore. I dropped the filter and immediatley was shocked at what I saw. Silver oil. I drained the pan and the oil has so much metal in it, it was unbelivable. Changed the oil for the third time hoping to save the engine and still no pressure. I am sure whatever came loose has already trashed my brand new motor. Any ideas, I have never had one come apart that far into the break in period. I have thrown engines together with used pistons and rods and crank into a block with a big cylinder ridge and never had anything like this happen. I am so disgusted I am sick to my stomach. Any ideas what could have caused my issue. I am not going to tear down the engine because it should be under warranty. I am just looking to see if anyone else out there has had issues with blueprints and how they do their warranty claims. I want to drive my car. I have worked on it non stop for a year.
