Code # P1399 = misshift owns joo

I looked on H-T for your code but no luck.

Good lists. I can look in the service manual today and see if P1399 is a valid code. I feel you on your misshift, been there, done that

Only a boob would mishift! Just kidding there seem to be a lot of mis-shifting stories around here. Fortunately mine (from years ago) had an uneventful ending (3rd-&gt;2nd).

I don't know what that code is, but I'm not sure it really matters. There's no code for "hole-in-piston, valve-in-oilpan".

The closest thing I found was DTC P0139: Secondary Heated Oxygen Sensor (Secondary HO2S) (Sensor 2) Slow Response

Ok, something real close to your problems:

DTC P1336: Engine Speed (RPM) Fluctuation Sensor Intermittent Interruption

DTC P1337: Engine Speed (RPM) Fluctuation Sensor No Signal

No, wait I found it.

DTC P1399 - Hole in Piston (HP) Valve in Oil Pan (VOP)



p.s. google came up empty except for someone saying it isn't a Honda ECU code. It was seen when the engine was misfiring.

Thanks for all the info guys...im going to do a compression test in a little bit to see how it is and ill let you know the #'s but i think im gonna have to start tearing the motor apart....it runs and has power cause i had to drive it home from the track cause no tow truck would drive it but sounds like ****(the exhaust sounds like a wrx its wierd). The p1399 code came up and said pending next to it and i still cant find what it is this really sucks

Could be worse! Sounds like good news to me. Let us know how the rebuild goes.

Did you have any transmission-related mods? Short shifter? Lightened flywheel? Grippy clutch?

The one time I did mis-shift, it was on all OEM parts and had time to put the clutch in before anything really bad happened. I went from 3rd to 2nd gear.

I have a short throw and had a skunk 2 shift **** on, stock clutch and flywheel and ill keep you guys updated on the build, it should come out very good

You're not the first with a short-throw shifter to have this happen (although stock shifters do the same). What about cams (and cam timing?) I wonder if a more aggressive cam would cause damage to be more likely?

ITR.#1446

I ran with completely stock motor, advanced timing to 19 degrees, full exhaust, intake, throttle body and fpr.
