New way to break your honda...

[HONDA GHANDI]

Heres a new one, I am working on a blown K series and found this. A free cookie for whoever can tell me the cause.
Beleive it or not this motor ran, poorly. The owner should go buy me a powerball ticket because he is the luckiest man alive that this thing didnt suck a valve and destroy the entire engine.

he took weight reduction a little too far?

:rofl: he took weight reduction a little too far?

You crack me up David. :rofl:

Hrmmm he did a valve job himself and never really adjusted the valves to where they were supposed to be?

BTW, clean your damn fingernails. ;)

How many were broken and what is the cause of something like that?

[exciv2000]

overrevving. lack of engine oil. dumping the clutch at redline. mtbf oil additive. What kinda cookies are they? :D

All the intake valves and about half the exhaust.


overrevving...


DING!

The engie was overreved to the point where the valves floated off the rockers. The rockers then fell down between the side of the stem and the retainer chipping the tops off the valves. Not normally you would never see this damage because the valve would break off and fall down inside the engine. However, this very smart and lucky person realized what had happened and shut the car down right away. The car ran poorly at idle and had several misfire codes. Compression was 140-0-30-125. The tops of these valves got caught in between the rockers and the valve stems causing them to hold the valves when they are supposed to be closed giving it poor compression.

Scott gets an e-cookie!

Any idea how high the revs were when he missed his shift? I'd say he's pretty lucky the pieces of valve stem didn't end up in his combustion chambers.

Man..what a waste of a nice motor. :( I imagine its not real cheap to fix that either.

Its easily fixable. If one of the 13 broken valves had dropped, then it would have needed an entirely new engine.
