Complete Machine Shop Service

Bob Forrest Engine Rebuilders has been in business for over forty years. We pride ourselves on performing the highest quality machining of engine components in the Willamette Valley.

Pressure Testing and Magnafluxing

Bob Forrest Engine Rebuilders believes Pressure Testing and Magnafluxing is vital and neccessary.  What you can't see, can definately hurt you!  

Cylinder Head Welding


Don't use a file or a belt sander on a cylinder head or deck.  Just because someone did it on YouTube does not mean it's right.  Bring it in and let us machine a surface for your vehicle.

Engine Rebuilding

Whether you need a few parts assembled or the whole engine, we do it right.  Every engine build by Bob Forrest and Mike Sanchez is done right the first time.  You may have to wait, but when it comes to YOUR engine, we do not and will not take shortcuts. 


Everything Else

We are a machine shop, plain and simple.  If it involves metal, it's what we do.  If you broke a bolt off, stop messing with it and bring it in.  Need something random, we probably do that too, just ask!
