Oil pan off, NEED OPINIONS ASAP!!

[1glaserfwd]

Well long story short I put a new engine in during the winter 2.3 stroker with weiseco and eagles. Machine shop that assembled my bottom end put a paper gasket on the oil pan and its leaked after the first 20 miles. I wanted to fix it so I pulled the pan off today. Engine has a total of 245 miles on it since rebuild. I noticed when I pulled the pan off what looks like a hot spot on the crankshaft. I have never noticed this on any other crank so wondering what it could be. The other thing is I have a heavy clutch so when I push the clutch in the rpms will drop a bit and come back up when I let it out, so I thought I would see if I could move the crank back and forth. It does and seems a bit excessive. Now I am all stressed out this is not good!!! I attached a picture and a video. I would really like somebody with experience with engines to give me there opinion. Thanks guys I really appreciate it, I hope to get some answers fast as I need to get it back together! Thanks again!!

Pull the bearing cap and see if it is showing heat as well. Hopefully that is just heat from a previous spun bearing and the crank was turned and repaired. If that is current damage the motor is coming out unfortunately.

Crank thrust is beyond excessive and as danl said, the heat on that crank is from a spun bearing, ether current or past. Are the thrust bearings in the wrong cap? That could account for the massive thrust play.

I am far from a noob have had 4 DSMs, and work in a mechanic shop! However when it comes to bottom end of an engine I'm a super noob!! Which bearings are the thrust bearings? How would I know if there in wrong place? I'm grabbing a tool to measure the play now. If its way out how is it corrected?

 

[donniekak]

That engine has crankwalked. The crank, and possibly the block are junk. Maybe your clutch was mis adjusted. It looks like the crank was forced against the thrust bearing excessively.

 

[JusMX141]

That needs to go back to the machine shop that assembled your low end- they either used the wrong thrust bearing or didn't align it properly prior to torquing the cap.

 

[Blindsey]

Such a bummer. How will we know if it wasn't aligned or the wrong bearing?

 

[1glaserfwd]

Ok so your saying a clutch being mis adjusted could cause crank walk in 244 miles? I need to know if you guys think this was a mistake by the machine shop. I am FOCKING PISSED!! SO much time and money spent on this damn car. I am praying it was the machine shops fault cause I dont have the money to fork out for another engine build!! I measured the endplay and its .030 and I guess max is .07! Think I might just puke!!

 

[donniekak]

If the clutch master rod was over adjusted, the fork would constantly press against the pressure plate. Ask the builder what the thrust play was at assembly.

 

[1glaserfwd]

Well the clutch master rod was adjusted out as far as it would go, if it was any farther screwed in the car would not go into gear. I am sure it wasnt .030 when it left the machine shop. I have never heard of a mis adjusted clutch causing this much of an issue before. Anybody else have any opinions on the clutch adjustment causing this?

 

[TJCTalon]

Theres no way a clutch alignment issue cause that much crank end play in under 250 miles.

Some dsms take 100,000+ to get that much play.

Someone had no Idea how to assemble an engine. The crank looks new too, if so that heat spot happened with in the 250 miles.

How does the oil look??

 

[1glaserfwd]

Oil looks pretty nasty, but I thought it took awhile for it to look clean. I have changed it 4 times in the 250 miles! Coming out it looks pretty dark and its a bit shiny.

Here are the pics of that bearing that had the hot spot on it. It looks toast!!
Looks like I had a 16 year old dumb ass kid putting my 600hp engine together!!

Was your block line honed for the arp studs?

 

[1glaserfwd]

It was supposed to have been!!

 

[JusMX141]

No clutch would do that in such low mileage- like others have said it was either mis-aligned, was not align-honed after the studs were installed, or the thrust tolerance was too excessive at assembly but I find that hard to believe with new bearings. The first two would be 100% the fault of the shop that assembled the low end.

Was the crank new or used?

 

[1glaserfwd]

I bought the short block from a guy on here. When I received it had a scratch in the sidewall so I had this local machine shop pull it all apart and make sure all was good and reassemble. The engine was advertised as only idled. The machine shop confirmed the parts were new but that the piston rings were installed upside down previously. The crank was advertised as new, as far as I know it was new.

 

[bigbird94]

I would get ahold of that machine shop ASAP.

 

[1glaserfwd]

So what is it gonna need to be right again? I am praying the machine shop doesn't tell me to screw off!

 

[TJCTalon]

Well you bought a used engine then took it to the machine shop to have checked? Used engine is a used engine. Unfortunatly Im affraid the machine shop will say F off. Thats the risk of buying something used.

I wouldnt warranty something I didnt build. Why would they?

 

[1glaserfwd]

I understand that but it was idled, they agreed took it completely apart and reassembled it! Obviously wrong! I specifically told them the situation and told them i wanted them reassemble it and make sure it was good to go! I paid 500 dollars for them to #### it up!

 

[Abe'sGST]

I'm confused. You bought a used short block from someone here, so what all did the machine shop do?

 

[1glaserfwd]

I guess we can all say USED! Motor was idled for 5 minutes and guy parted it out! I bought short block. Upon arrival I noticed a scratch in cylinder wall that I wanted to make sure was not an issue. I told them the story wanted them to completely disassemble motor and make sure it was fine and reassemble. They called said piston rings were upside down and all parts were new, and they would reassemble and all would be good! 250 miles later motor is junk!

 

[n0de]

Well that had to do something in order to charge you $500. You'd be a fool if you spent that kind of money to have them just look at it.

This sounds like something the machine shop needs to fix.

 

[MY1GDSM]

Man... This just sucks too see. Another Trans then THIS!

Good luck with everything and The machine shop. If they reassembled the motor and called it good. I'd say they have some responsibility here... . Hope they feel that way too... .

Hope the Car is back up and going soon. Sorry, about the luck.

seems like when you buy a used bottom end you have no idea that its been through, since they all seem to look the same unless you really know to dig in deep and measure all the tolerances. Theres a guy named jafromobile on youtube, that demonstrates how to measure an engine and determine when it needs to be machined before putting back into use. Educate yourself, so that y ou can better communicate with the machinist. but yeah this is what im most afriad of, after putting thousands of dollars into an engine to find stuff like this.
