I need a Bare block

[djmixerx]

Anyone around the bay have a 6bolt 4g63T bare block they wanna give up for cheap. I was just told by someone that my new motor is crap!! . Needs a rebuild less then 100 miles. Yes 100 miles!!! fking SUCKS ASS!! Donations would be koo but I know dsm'ers need the money. Let me know what you have.

Thanks.

who is that someone that told you your new motor is crap. who built the motor? and what did you do to mess up the block.

The only difference between the turbo and n/t block is the knock sensor right? I have a n/t bare block if you want it.

 

[djmixerx]

Its a very known dsm shop in the area. As for the N/T motor the difference is theres no oil squirters.

 

[unlmtdndeavor]

so the shop that built the motor also are the ones who told you that it is bad?

 

[djmixerx]

Nope someone in fremont built the bottom end. It was not balanced that well. it has piston slap.

wait, so not all dsm'ers have spair blocks in their garage?

am I the only one?

hit me up on email, I'll pm you my adress, my pm box is full though....

i have a spare motor...but it's going into another project. get at single nut^^

Piston slap doesnt mean that your block is bad/needs a rebuild.

Who ever built it, probably didnt check the piston/cylinder clearance and its probably a little loose. Balance wont cause piston slap either.

Looks like someone just wants some money. Just run it until it wont run, seeing I'm going to guess its a "stock" rebuild by your profile. Save up for a built block later if you are worried.

Piston slap doesnt mean that your block is bad/needs a rebuild.

If you do not want a performance engine then small amounts of piston slap is tolerable but annoying and causes premature cylinder wall and piston skirt wear; this wear would be rapidly accelerated if your engine had extreme rod angles like a 2.3 stroker. If you are planning on having a performance engine then you do not want any slap/chatter/wobble/whatever you want to call a piston clearance machining error. If you happen to be using an Engine managent system that is knock sensor dependent (factory ECU, DSM link) you will have tuning issues which will become compounded if the engine is also not balanced correctly.

Who ever built it, probably didnt check the piston/cylinder clearance and its probably a little loose.

If a machine shop didn't check the clearances of the piston there is a good chance they didn't check other vital clearances.

Balance wont cause piston slap either.

DJMIXRX never said the balancing issue caused the piston slap. "It was not balanced that well. it has piston slap."

An engine being out of balance is completely different from having piston slap. If you had a machine shop build you an engine and the engine has both piston slap and is not balanced correctly then you should not go back to that machine shop. Robs Auto Machine in hayward and S&S in San Leandro both get my thubs us.

There are a few ways of fixing piston slap.
1) different block that is bored to the correct clearances. Approx $300-500
2) new pistons the next bore size up. (don't have the same machine shop do the bore and hone) $450-600
3) Knurling. This is a very old way of correcting small amounts of piston slap and isn't recommended for performance applications but I have seen people get positive results on ocassion.

There is only one way to correct a poorly balanced engine.
Tear it apart and send the entire rotating assembly to a reputable machine shop.

There are several options available with your engine's situation. I hope this post broadens your menu. There are several members on this board that can help you.

Easy there turbo... He never said it was a 2.3 and in his profile it states "stock" so thats what I took it as, if you couldnt see it from my original post.

If a machine shop didn't check the clearances of the piston there is a good chance they didn't check other vital clearances.

From what I read and what he has told me, it was some guy that had the block machined and then assembled it himself. So there for if that is true you cannot really base this on the machine shops fault. The person that assembled it could have told the machine shop they wanted a larger piston/cylinder wall clearance, or if they told them nothing at all, they would base it on the specs that come with the pistons.

If I remember correctly, Ross pistons "SUGGEST" .006 piston to wall clearance with an additional .002 thou for turbocharged applications. Which in return is very sloppy and will cause quite a bit of slap. I know it has Wiseco's in it, but those are the specs I have on the top of my head right now.

DJMIXRX never said the balancing issue caused the piston slap. "It was not balanced that well. it has piston slap."

Sorry, I took that the wrong way, I guess I read it a little fast. I didnt see an "AND" in there or the period and took it as if the balancing somehow caused the piston slap. After talking to him, I understand what he was saying.

An engine being out of balance is completely different from having piston slap.

I am very well aware of this as why I stated it in my first post... Again, how would the machine shop be at fault if they didnt assemble? Balancing is an option. Whoever built the block, probably didnt want to spend the money on balancing the crank.

Also, not sure what "get my thubs us." means... Is that good?

YOU BEST not be talkin about lily's engine, ### I already told you, Im gettin that shit running with my spair parts this next school year, you ALREADY know that.

if thats the case, I might need to keep this block too and throw it in lily.

you need to give me a list of the shit you've stripped from that car so I can get it ready for when I make the trip down there.
