This is Part 4 of a 7 part video series documenting the replacement of cylinder heads on the Toyota 3.4 L V6 5VZFE Engine. There’s many reasons why you might find yourself needing to remove the heads. You could have a suspected bad head gasket or cracked head. You could have a suspected issue with the head, like a burnt valve, and you need to rebuild the head. It could be because you’re rebuilding the entire engine. Whatever your reason to pull the cylinder heads, this video series will walk you through all the steps necessary to get the job done successfully.

In Part 4, we visit Yota1 Performance in Riverbank, California to show you how engine cylinder heads are torn down, inspected, vacuum tested, pressure tested, resurfaced and built up. We spend the day in their machine shop with Allen who has 45 years of experience in the Machining and Engine Rebuilding Industry.

Nick and Rebecca, the owners of Yota1 Performance, were gracious enough to invite us into their shop and let us do some filming. We owe a huge thanks to them!

We hope you enjoyed and appreciate the tech we were able to share with you in this video.

Happy Wrenching!
