That is very unhealthy

OUCH!:bigeyes:

lets see yours tricky. you can't build that many high hp motors without at least one catastrophic failure...

Not Again :scared:

I just curious, what kind of RPM are you turning on that engine?

Type of pipe, compression, octane fuel, jetting, ignition timing, dome cc's, squish clearance, etc?

That was 2 blow ups ago. What caused it was to much compressoin. it's being rebuilt again now.

I have had a couple, but this one was the bad one. Rod snaped on OEM crank @ WOT. 85mm flat top lamey ~200 psi. The complete bottom end was trash. I Repaired the cylinder and it is running again today.

do you have a pic of the motor still assembled with the rod sticing out? good job on busting up the intake manifold too. :headbang:

Ahh....just change the o-rings....it'll be fine:biggrin: j/k

See what happens when you use OEM piston return springs?

 

[Idok]

come on matt E....we know you got some too!!!!!





right now I have a comeplete bench full of blown motors..will post some up tomorrow..

 

[Matt_E]

Eh, I knew someone was going to involve me in here. Let me look.
Okay, found it. This is disturbing...I had a folder setup for those types of pictures.

I think that might make a lean condition. better fatten up those carbs. :biggrin:

 

[Matt_E]

Hehe...that happened right after I ported & bored up my cylinders. In retrospect, I know exactly when that "oops" happened, but at the time, I Didn't know any better. I was trying to adjust the carbs to get that lean bog cured, but no amount of adjusting would change anything. ANd why was there a white miilky substance in the bilge? :aargh4:

Later that day....:17: :17: :17:

 

[WaveDemon]

I was trying to adjust my carbs to fix my piston problem also. I finally checked the comression and got 5 in one and 80 in the other. :bigeyes: :aargh4: :cussing:

 

[Matt_E]

You live in FL, I live in WA...yet I know exactly what you would have felt like. :biggrin: :17: :scared:

You got any pics of the one Casey trashed at Lanier last fall?

 

[RoyalFlush@PCB]

Here's one of mine...

 

[willycrumb]

Just for craps sake....how long did you wait to take that apart after the faliure? Just wondering how long it took for that rust to show?
