It b seems that the OS V-Spec isn't the only OS engine to have this type of problem. I read the new issue of XRC and they did a test on a truggy in there and used the new OS .30 big block engine. It died after one gallon and the guys doing the test openly admitted there was something wrong with that engine as well. I have an older VZ .21 and a RZ .21 and i liked both of those engines. They were'nt power house engines.....but they certanly ran more than a gallon. i hope OS does some more research on their VZ-Spec engine. I also hope that they do a little more testing on their engines before they put them out on the market.
