For all of you with, or contemplating the purchase of, a Roush crate engine, you might want to read the following warranty exclusions from their website: Specifically, it suggests that these engines are set up with loose tolerances and
oil consumption is going to be higher than normal. If you can't live with that, then you might want to consider another engine manufacturer.
"ROUSH Crate Engines are high-performance engines that are based on and operate like the engines designed and produced in the 1960s and later. However, unlike engines of that time, Roush® Crate Engines (like other crate engines currently manufactured in the marketplace) product significantly more power and torque. As a consequence of this, these engines have characteristics different from the original production engines upon which they have been based. The following characteristics are not covered by the Roush Crate Engine Limited Warranty and should be considered before purchase.
Specifically, Roush Crate Engines:
■Are assembled with larger operating clearances
■Will likely have a rougher idle due to the high performance camshaft design
■Will likely make more mechanical noise
■Will likely consume more
oil during normal operation
■Will generate more heat due to the increased power level
■May exhibit non-production-like drive characteristics at various speed and load conditions
■Will likely consume more fuel due to the increased power level"
