i recently put in buddy club cams and a few days later after it was running good i went to downshift and BOOOMM!! blew something...it was loud..so i just pulled off my head tonight and here are the pics! its ugly!

BEFORE!

 

damn

 

pics are big oppsss...but i guess its time for a rebuild huh lol....

 

Any valvetrain upgrades?

 

yeah that was the problem according to buddy club the spec 3's are fine with the stock valvetrain...guess not i didnt even go past 8k on them....but im upgrading everything now even the pistons..the head can be fixed right? i havent seen anything like that before

 

are those the factory vavles?? or what are they.

looks like they took a poop on you there........ what was the engine speed at the time... that sux bro

 

i had factory b16 valves/springs/retainers...i had buddy club spec 3 cams which were supossed to be ok with the stock valvetrain aslong as you dont over rev them...i was just shifting from 4th to 3rd or 3rd to 2nd i forget...i wasnt even going fast...it happened at about 7 grand

 

damn that sucks man... ive had the same thing happen to a few friends of mine... and that motor was fawking clean... the car still is though ... good luck on the rebuild

 

Where did you read that theyre good w/ factory valve springs??
You should have upgraded them.

i emailed buddy club and they said an upgraded valvetrain is not recommended but they suggest it...also search on here and there is like 87484 posts where people say its fine with stock..but i learned a lesson and i get to upgrade to ctr pistons and omni valvetrain..should be putting up good #s i hope

 

Yeah, doesn't look like the valves held up too well. Clean Sol though, I miss mine :'(

that sounds like a double negative to me lol... i think you mean it doesnt require an upgraded valvetrain but they suggest it... i would NEVER install any high lift cam without atleast upgraded springs and retainers... the stock springs are just too weak to close the valve quick enough due to the high lift... so thus you float a valve and the above happens

 

its not the valves that didnt hold - the springs didnt pop the valve fast enough and the valve and piston met and made baby parts

What they said makes zero sense.

If an upgraded valvetrain isn't reccomended then why would they suggest it?

Or did they say that an upgraded valvetrain isn't required, but they reccomend it?

edit: peckerhead 2 posts up beat me to it

who you callin peckerhead peckerhead

 

meh, called valve float correct? Cam spinning too fast for the springs to move the valves where they need to be ...

Shouldn't there be a comma between those two peckerheads? lol

Anyways, did they say that it was not reccomended, but they suggest it?

Or did they say "It's not required, but we reccomend it"?

haha yeah sorry i wasnt paying attention...they said it doesnt require an upgraded valvetrain but they suggest it... sorry lol

 

ouch. nasty. how did the buddyclubs feel before this happened?

 

damn, that is fubar'd

 

damn, that suxors mad donkey bawls

 

stock valvetrain on bc3's.. ok dood... don't touch engines anymore..

 

What happened is that you altered your engine's cam profile. The overlap was too much. the stock B16 is meant to have that much of an overlap, but with that cam, the intake didnt close fast enough, and the exhaust valve probably hit it, cause the valve went in more than was suppose to.

head can't be fixed, thats fucked... new head required... the block can be saved...

 

well if the say you don't need an upgraded valve train, then i would call them and see if you can get some type of refund. That is if that what was said.

good luck with the rebuild, you could maybe save the head but im not sure, block is fine though, just new pistons and a hone. good luck man
