This a motor I recently rebuilt it Snapped a rod in half with only 13 miles on it. I also bent an exhaust valve

 

ouch sorry to hear man

 

 

Who ever did the work didnt do it right! Sorry to hear

 

well you know what they say . practice makes perfect

 

That sucks.

Every time I see this it makes me feel about rebuilding my B16A. No wonder I've been procrastinating.

Sorry for your loss, I hope your next one is bulletproof.

 

ouch sorry man that makes me cringe jus looking at

 

Its funny you say that this motor came out of anyone of my own cars i was the one that did the rebuild. I know what everyone is going to think but this is not my first rebuild but it is the first that snapped a rod right in the middle don't ask me how because I know the stock rods are good for over 300 whp. I cant call it bad luck but I am really upset.

No worries though I already had a spare block that was rebuilt a while back I took it out of my car. It was a 92 ls, But I was hoping to use it for my ls-vtec setup I was about to do but I guess this will have to be done right now. I have several motors in my house right now anyway I have a jdm b16 but i need to replace the valve stem seals. I have my turbo gsr motor that needs rings ( that's where the original block came from)

I bought the bottom end from a friend it already has forged rods pistons and rings with a block guard and a Type-R oil pump. So I used this gsr block with another b16 del-sol head I picked up from a friend. But its ok the coupe will have to wait I'm going to focus on my autocross hatch so I can put in a 2000 single cam turbo.

 

Was this one boosted or anything?

 

No this was for Just a simple O.E. rebuild and this block has never evr been boosted for the 5 years that I have had it or prior.

 

were you reving the **** out off it when this happen. i wanna find out the problem. did you notice anything about that rod when you did the rebuild?

 

eh 13 miles??

id say inproper rebuild. I mean look at the cylinder wall on the left- huge grooves down it, buildup on the top- did you even hone the cylinders? I see no cross hatch-

What were your P/W clearances?

what were you rod bearing clearances?

 

funny you say that i honed the **** out of it and Ill be honest I think it was improper rebuild to I wont lie. I haven't taken the pan off so I want to see the condition of the rod. I could be wrong but this is what I think happened. If anyone has rebuilt a motor you will know what im talking about.

When I put the motor together I always start cylinder no1 and over to 4. When I got to 3 I flipped the motor upside down and the rod bolt slid up a little so I checked it and fixed it and torqued it down. I am assuming the same happened to cylinder 1 but I never rechecked it. So that is where I F*ed up. I usually check my work 2 maybe 3 times and I didn't. This is a lesson learned no matter how many times you have done the same thing always go back and check again and again for good measure. and the cylinder no 4 looks like that because i have had it without a head for a couple days now.

 

engine really doesnt like you

Horrible first post

 

So you think it's cuz you didn't have the rod bolt torqued right?

 

could be or maybe the rod bolt slid up a little and I didn't notice or maybe I over torqued it. I will know more when I pull the pan off so I can see the dead remains. Ohh and EKFG I wasn't not revving it up i need to brake her in so i knew to keep it under 4k for at least 500 to 1000 miles.

 

that sucks

how many steps were you doing to torque the rod? sometimes ya forget to compelte a step or somethign ya know?

 

wow that really sucks. gl with the rebuild..

 

watever you do dont rebuild yourself your nuts

 

I have been building motor by myself for over 8 years believe me unlike you I know what I'm doing. I might have missed a step like I said i just got to comfortable. Just goes to show you like I said check and recheck your work.

 

The fact that you admit it was your mistake and tell us the reason it F**ked up shows your a classy tuner; as for egallmotor unless your perfect i wouldn't say ****

 

yeah.. sounds like a simple mistake, not a bad rebuild. Bad rebuilds usually last a few thousand miles until they're back to where they were before the rebuild. Definitely check the pan to see what remains.

 

b20 vtec time.
