We take an tried and tested approach to getting your engine in tip top shape. Valliant Industries Inc. will disassemble, clean, and inspect every part. All damaged parts are replaced. We place all new gaskets, seals, and the latest lubricants to give you an engine that meets or exceeds OEM standards. If machining is required we will get that taken care of as well!
