Well I was driving home last night because prostreet closed a lil early so I couldnt make it to get a Valve Adjustment, well once I got on the 110 Freeway I heard the most disappointing sound, Valve to piston contact. Could anyone here tell me, why this happened? Did I over look something? Well I will be picking up an LS block bored to 81.5, is there anything I need to do before putting it together? Any help would be appreciated, here was the setup....


B20b Block (Completely Stock)
Golden Eagle Headstuds
Type-R Water Pump
Type-R Oil Pump

B16b Head(Stock Port)
Skunk2 Retainers
Skunk2 Valve Springs
Skunk2 Pro Series Intake Manifold
Buddy Club Spec 4 Cams
Stock Injectors

 

Nobody can tell you why you dropped a valve exactly, though it most likely has something to do with improper installation of the retainers/valve keepers....

A picture of the damage would be a bigger help than a shopping list.

 

i'm thinking the problem is the "completely stock" b20b block and buddy club 4 cams not getting along

ok yeah thats wat im thinking, well its blown now, taking the motor apart in the morning so ill try to get pics up of the damage.

 

Why on earth would someone put BC4 cams(or for that matter anything larger than a type r profile) with a stock B20 block???

Judging by your sig, Prostreet has allot to learn

 

I find it hard to believe ProStreet would assemble a motor like that. The B20 pistons just dont have deep enough valve reliefs to accomodate big cams like the BC4. How long did this setup last?

 

NO NO guys prostreet didnt but this motor together I did, please dont blame them, I was running it stock block until I got my rods to put in all my other parts. Prostreet did my last motor setup

believe me, Prostreet (Eugene) is extremly knowledgeable about Honda motors.

Did you drop a valve or bend a couple on the domes?

well, you live and learn. Hopefully, you'll never run cams in a vtec head with that much lift on pistons that don't have the vtec valve reliefs.

Even if it did work, you wouldn't make power on such low compression.

Well I'm glad to hear that he did not assemble this motor

these 3 things dont go together that well (i know it wasnt the injectors fault)

like they say, live and learn. you cant teach experiance. at least you have a good attitude and didnt come in saying how shitty b20 blocks are lol

gl with your next build

Yeap, unfortunately several of my friends have experienced this event. You really need the pockets machined in the pistons even with B16 cams. Type R or larger it is a absolute must.

 

stock pistons without valve reliefs and big cams with vtec heads dont mix.i dont think he droped a valve ,he bend some valves...

 

thats rite what jcushing said,good attitude cause b20at 85mm tuned rite dont blow up.and are some bad *** motors for n/a.i got one coming soon...

I forgot where I heard/read this quote but I really like it...

A wise man learns from his own mistakes but a genious learns from the mistakes of others.

With that in mind, I try to make different mistakes.

yeah well imma try again this time with a LS block but going to be throwing in CTR pistons, anything I should know about this next build so something like this wont happen again

 

goood luck!

 

make sure you put so good pistons in there!!! Also did it do damage to the head ???

 

you drove the your car without getting the valves adjust? did you hear any kind of clicking while the engine was on idle?

No motor idle between 800-1000

Clay the motor. Although it should be fine but if you would've done that with the b20 block you would've saved yourself a rebuild. Why don't you just get new pistons to go in the b20 like the ones made by rs machine. Don't forget the arp rod bolts either.
this will help also:

yeah I took the motor apart and lucky no cracked sleeves or ne thing, but the sleeves will need to be bored and honed, so ill probably just bore it out to 85mm, and just use this block instead of getting another one. Wat do u think? Use 85mm RS Pistions?

 

85mm on stock b20 sleeves are going to be paper thin. better relseeve first if you want that kind of bore.

yeah, dont use ctr pistons.
