The cylinder walls appear to be in good shape and the short block may be salvageable. In any case it'll require a rebuild but may not be as bad since a large chunk of the cost is in sourcing a good block nowadays.

Hopefully, it just needs a light hone and rings.

 

What a range of opinion here - from "light hone and rings" to "engine is done." Geeeze. I suppose if you are young and energetic and skilled, if you do all the labor yourself, and if you have all the time in the world, you could pull the motor, disassemble it, do some measurements, maybe do a hone and rings your self for next to nothing in parts, put it all back together, reinstall the motor, and see what happens. Or, if the measurements are too far out of whack, you could search for a good used motor at that point. Or, you could just source a good used block and be done with it. You could sell the motor as is and let someone else try to rebuild the old motor. That is what I would do, mostly because I am not young and I don't have the time, or the energy, to do all that labor 100% myself.

 

Do yourself a favor and read through my previous posts regarding a (or several) builds through Inline Pro.

 

You can get used F20/F22 for much more reasonable prices than on eBay. PM me and I will be happy to connect you with a warehouse in Sacramento stocked with plenty of F series engines. I recently bought my F22 with 100k miles for 2800
In my opinion buying a stock bottom end is the most reliable way to go.

 

Head is off with the help of Tony Fuchs.

Cylinders (1 and 4 below) look fine but #4 valve on cylinder 4 doesn't.

Hey that’s good news! You might be able to get away without touching the bottom end at all. I’m guessing you’ve moved down to SoCal since you’re working with Tony. You’re in good hands.

 

Damn, so I guess my WAG was right, your exhaust valve was bad.

 

Yup moved to LA a little bit ago, glad the forums pointed me to Mid Valley Auto. Fingers crossed its just the head. Good call @Slowcrash_101
I'll keep you all updated

 

Weird. Why the leakdown results?

 

The leakdown said he was missing compression, not exactly where. Everyone assumed it was the bottom end, but the cylinder bore looked too good to be a bottom end problem.
