I just bought a 2007 Outlook XR FWD(210,000miles) with only 50psi in cylinder 3. It should be 140psi. I will verify before disassembling the engine. I plan on doing it myself and would like to know if anyone has had experience doing an engine tear down. I bought it from my aunt and know that it has had a very good service record. The timing chains have already been replaced, but nothing has ever been done to the transmission.
