Nominal leakdown test numbers for a f20c with 45k?
My compression is 216, 216, 216, 214. Those numbers are 20 points lower than my old numbers i had before i sucked some water up.

I believe all motors are different, as long as they are close its all good. Someone will correct me if I'm wrong.
im ok witht he compression numbers that the dealer got, but tomorrow they are going to do a leakdown test

When you do the leak down test make sure you didnt wash the cylinder walls with fuel. (when you do a cranking test and dont disable the fuel, it would wash the oil off the cylinder walls, and may or may not show you a leak that wouldnt be there with the oil on the rings).

You do a leak down test with the key off, after the engine has been running at operating temp. Then you rotate the crankshaft by hand with a ratchet, once you get the tester hooked up to each cylinder.
You don't spin the starter over for a leak down test like a Compression check.

wow. morons. 10-15% leak on EVERY CYLINDER is NOT "good" in any way, shape, or form. what asshats. i hope you told them to shove it. even the helm's manual or honda manual tells them those numbers mean something is wrong.
