Yes I will be getting sleeves from John. #4 for sure has to be resleeved so might as well make em better.

Crank looks ok but I'm not going to reuse it.

 

Why won't you reuse it??

 

Just get it checked/mic'd

 

I have 3 cranks to choose from lol

 

Hook a brotha up!!

 

Asked first. dibsies.

 

After I tell you shipping from Canada you won't want it lol. What's so special about the crank you like? That its knife edged and polished?

 

Ehh ill get one in the states haha

 

Doesn't Mongorat have like 10 stock cranks?

 

what would the scoring on the walls have come from? a bad hone job or just f'd up sleeves to start with?

 

Why can't you just replace the bearing

 

When I received the motor and looked it over in 2 cylinders there was some very light scoring at the top of tdc that honing wouldn't take out. They most definitely were not horizontal like billy says. I don't even know how you would get horizontal scoring in a cylinder. Well the scoring got worse in one of the cylinders again once the motor ran. I couldn't probably hone it again and be the same as when I got it but that's no good. So the motor has to be resleeved with new rings and bottom end bearings.

I'm sick of staring at my car broken so that's why I threw the other motor in. Plus it was a great deal.

 

Sell the crank and when you go to Bismark in august to tune ship it from there. ;P

 

I have a text in my phone about talking about the scoring. And 2 if you did clean the bottom end (after the motor was shipped and sat for over 2 months) if u sprayed any kind of cleaner through that bottom end or took anything apart and didnt reapply assembly lube,not oil, assembly lube, then I'm surprised every bearing wasn't thrashed.

I really did nothing wrong man. Every single part in that engine e was brand spanking new and I showed you pictures of everything and told you every clearance I set in the block. I built 2 other engines for forum me member and both over 2 years old and still run great. I'm sorry it happened and I know from now on in wont be selling any short block with the pistons exposed to the outside air for over 2 months with no head on it.

But all in all, that pic you sent me had thick gouges, literally 50 or more on that one wall. The 3 light scoring marks before did not cause that. One grain of sand, metal, oil dry etc, can thrash a cylinder wall like that.

 

I was in the car when it got tight. We put a safe base map on it because I wanted to ride in it and make sure the car was sound before we leaned on it. We dialed the timing back to ramp to 19* up top and did a 2nd gear pull to 7800 just to see where the fueling was at. Was a bit rich up top (low 11's) and we were laughing about how slow the car felt like that. Pulled over, leaned it out a little and did another short pull to 7800. AFR around 11.8 this time around, but at the top of 2nd it got really sluggish. Thought maybe belt slip so he grabbed 3rd and got back in it, and the car just sat at like 5500 and didn't want to accelerate. I signaled to cut it off and as soon as he could push in the clutch the motor went from 5500rpms to 0 in a split second. We both looked in the mirror suspecting smoke or something but nothing, which was at least good. As we were coasting down looking for a place to pull over I said "something got tight"...which was obvious lol

Dustin (Blue) was texting BIlly from my phone because he gets charged out the ass using his phone in the U.S. and he was responding quickly, I'll give him that. I can understand why he is upset though, especially since it was such a pain for him to get home. Pretty sure the U.S. tried to keep him in the country!

Thats just pretty much how it went down. Oh and sorry Blue but I had to share this. The little driveway we coasted into where we loaded the car up

 

So you think it still woulda ran if the bearing didnt spin?

 

2 cylinders had lower compression, but the bearing is what made it tighten up and become undriveable. The next morning after it cooled down it loosened up a bit and would stay running with your foot on the gas a little, but we didnt let it heat up again.

 

So the spun bearing is probably from getting dry after siting 2 months?

 

Honestly this is a question idk the answer to. If I had to guess id say no, unless it was in a hot environment where the already thin syrup consistently leaked off the bearings. I never built a motor and had it sit that long.

 

Man I wish I still had pic's of the cylinders on my old phone when I got it. I have people that can vouch for it that had worse than you are describing. But luckily #3 and #4 looked identical when I got it. And #3 is fine. So I will put pictures up tonight of the " 3 score marks" you are talking about. Like I said, I could hone #4, the pic I sent you and have it look exactly as I got the motor.

How can you say you did nothing wrong? If you would have said to me, "hey just to let you know there's some scoring on the cylinders but my machine shop said it would be no big deal" never ever would I have bought this motor from you. I'm a small engine mechanic by trade... I know how to build and prep a motor. This motor didn't fail from sitting, it failed from poor assembly.

The motor ran mint until I spun it to 7800 rpm. The motor got tight and would barely turn over. Come morning time the car fired up. That's a tolerance problem Billy and nothing else.

 

If u know how to assemble an engine why didn't you do it yourself

/thread

PS I'm a small engine mechanic too and its the same process

 

Dam this thread makes me nervous

 

Because the price was right on your motor. It would have cost me almost double to piece it together due to living in canada. Just good timing when you sold it.

You fucked up, there's no question about it. If you were a mechanic as you say you wouldn't have built the motor the way you did. And realized you made a mistake and reimburse me some money to now fix this motor properly.

 

Making popcorn who wants some?

 

What made the 50+ droves in your cylinder wall? Was there 50+ grooves in the block I sold you? No. Some contaminate was in the cylinder. End of story. Nothing else could have made those grooves. Please post the picture you sent me so people can realize that grooves like that don't just magically appear.
