I have a small amount of convo but unfortunately a lot of our convo was on aim so I made my first mistake there by not having my aim set to log convo's. Lesson learned.

While I want to take it to court just to teach people a lesson, I just don't have the time to do so right now. You know how that shit goes, and that is unfortunately how a lot of people get away with shit like this.

Lesson 2 learned, when doing a motor build, build your own motor. We'll see how this motor works but I really don't know how it will go in terms of blowby with those gouges being so bad.

Who knows, maybe I'll get lucky.

Just out of curiosity what did the guys at the machine shop say about the scratches? Did they seem to think it would be alright? Sorry for the misfortune...

Its going to be fine, but it is going to cause some extra blow by. I think they were under the impression this was going to be a high maintenance race motor (tore down and worked on every weekend). When in reality we wanted it to be a 100k mile, better than stock replacement. We didn't really have any other choice with his budget. Id have personally sold it back to him and waited to do the build a bit longer.

I do hope the guy sees the pictures. He kinda pissed me off with his "your guy is trying to milk you out of more money comments" Jon

Yea, that's bullS***. What amazes me is he either noticed the scarring and didn't care or he is just F***ing blind. It is pretty apparent even after the hone that there was substantial trash in the engine on the original build. The scarring looks like it is too high to be piston skirts.

**Z28pr0jekt** · 06-25-2009, 03:10 PM

Yea he was pretty adamant about trying to tell me that I knew of these gouges, when every single picture of the motor that I have, is also posted at the beginning of this thread.

If ya'll can see those gouges from those pictures, I must have a serious eye problem because I can't. If I had known about them I would've never paid for the motor. I was told that his car never had any blowby or problems or whatnot and I just don't see how it is even possible to not have blowby when you have 10 gouges right next to each other that are over .005-.01 deep

Run it.

Those gouges suck ass but they look like they are in normal places. Arent those from when the pistons are cold and slap around? I pulled my LS1 apart and all the tubes had them, all 8. But that was a 92k mile short. I suspect you got jewed a bit Ryan but you should know how it works. Kids are pricks and you get shafted with some parts but when its all said and done you will surpas your goals and not have a single issue.

Good Luck.

And you have to remember. When running forced induction you're gonna have blow by and theres really no way to prevent it.

Nah these aren't from piston slap.. these are from either the rings (maybe some of the scratches) but more likely something was in this motor either when it was put together or no air cleaner or something of that nature. These scores are over .005-.01 deep so the ONLY way to get rid of em is to bore it out.. then it needs new pistons/balancing etc etc.

Remember I posted pics in here of my stock 152k mile long block that was running rich as fuck and had the cc306 in it for about 15-20k miles. There is NOT ONE vertical mark on my cylinder walls. I understand that motor never had FI put to it but regardless, a motor should not incur gouges vertically like that unless it sucked some dirt through the motor or the rings were gapped incorrectly (In which case, the rings that came with it were completely at the wrong gap)

If the rings are gapped correctly (Which the previous owner had them all fubared) you should HARDLY have any blowby at all as long as they are broken in right.

The majority of my friends down here have FI cars and not one of them burn oil
