2001 FORD FOCUS 2.0 SPI Rattle Part 2
Started it up at work today and it was smoking bad, so I knew toady really wasn't gonna be good..lol I went to my buddy's house and punched the cat out and took off all the shields that were hanging down. Noise is still there, and is now getting worse. I believe it may be the dreaded SPI cam issue, or the crank has issues.. I don't think the video shows it well but the harmonic balancer is jumping a lot more then it has before. Just the fact that it does it all the time now and has chewed up almost a 1/4 tank of fuel in 20 miles tells me she's hurt.. 3 years on a 2 grand investment aint bad..

Buying A Used Ford Focus: Warning
Warning to anyone thinking of buying a Ford Focus car. The single cam split port 2.0 liter Ford Focus engine has a design defect in the valve seats. They eventually come loose and drop into the cylinders and destroy the engine. This is called a dropped valve seat. You can see what happened to my piston in this video. If you are thinking of buying a Ford Focus, or if you have one that's starting to run rough, your valve seats may be starting to go bad. My car ran rough for a while before it finally died. In this case it was possible to have the head rebuilt and install a new piston and connecting rod, and the engine runs great now.
