Spool Turbo MP3 Blew Up

[Bigg Tim]

That cylinder must have been running lean to have the valve that white.

pics of the bottom end/rod bolts...

the considerable damage to the upper oil pan...

THIS IS THE SAME THAT HAPPENED TO MY ENGINE. Piston 1 and 4 bent and twisted the rods up to the limit that the piston reached the crank shaft and got pulled out of the pin (broken under it) and left the piston in the chamber while the rod is playing around doing some decorative holes in the block.(pissed)

Hey, and about the head gasket, maybe its not aligned in the block because the alignment pins are stuck on the head and not on the block. Look for it.

the pin is still in the piston though.. and the piston isn't twisted all that much off center... but yeah I follow you for sure!!

I'll have to look for those alignment pins.... never saw any sign of any of them.. the gasket was just floating around when I pulled the head off..

Have the blown motor 100% apart at this point... Also have my new motor torn all the way down and am taking the block and crank in for machining. I am/was taking the crank in for balancing reasons, but looking at it after pulling it out it appears that it may have been balanced by the factory as at least one of the lobes has metal drilled out of it. This motor I got is in fabulous condition as the cross hatching on the cylinder walls is still very evident. I'm going to have a glaze break done on it anyway and will be getting an align hone done on the main bearing seats as a good measure. I may look into having the crank knife-edged as well, not sure though at this point.

I'll be posting my archives of pictures up to our nsnmotorsports website. I have pictures of more or less every step of the disassembly. So it may be of use to some people. I'll post some of the good pictures Thursday when I have a chance to through them (I have a hundred plus).

Later!

isn't knife-edging the crank pretty expensive? or is that just getting custom knife-edged cranks that are really expensive?

 

[Brian MP5T]

Subscribing.

I've seen prices around a couple hundred. I am going to talk to the guy that I'll be using for my machining (also the guy who will do the machining for NSN Motorsports in general if you request machining through us) to see how much he wants for knife edging as well as his thoughts on it. I've been told that it isn't really worth it and from what I've learned it is really mostly a weight reduction thing similar to switching flywheels... so a flywheel switch is just that much easier really.

But overall the new motor will be getting:
Glaze Break
Align Hone
Block Deck checking
Head remachine for flatness
Full exhaust and intake port
Full exhaust and intake polish
3-5 angle valve job with back cutting
Valve swirl polish
Port matched intake manifold
intake manifold polish
chamfering cam galley oil returns
Deep cleaning and balancing of 8 550cc injectors
Complete rewire and regrounding of entire engine bay
CP pistons
Oliver Rods
High end main and rod bearings as well as excellent piston rings (brands in process of being determined)

I'll also be hand polishing all the exterior surfaces and painting the block Ford blue. Add that with my Microtech, dual fuel rails, Walbro pump, JandS safeguard and the like... this thing should move ok Assembling everything myself as well, just outsourcing machining.

Later!

wow. thats a GREAT list! (thumb)

btw, can you put all ur engine pics (blown) in a ZIP and upload it? (dont know if they are all here, or scattered around)

 

[TurfBurn]

I'll post a link for you on Thursday hopefully... I'll zip up the MANY pictures i have of all the blown bits and pieces and huge block hole.

Any questions or comments are very welcome... I have thought about moving this to a new thread to describe the rebuilds rather than people having to go through 14 plus pages to get to this stuff...

Watch Thursday for lots of pics and links!

Later.

Steve, my crank also had factory drilled holes. It still needed balancing though (machine shop drilled a few more ))

 

[LinuxRacr]

the considerable damage to the upper oil pan...

Upper oil pan = Main Bearing Support Plate (MBSP). Your s*** got eaten up! (eek2)
Why does this bring back deja vu?

Yeah you should see the piston itself and see the size of the hole in the block... it's at least as big as the upper oil pan mess (btw.. anytime you try to buy the part they call it an upper oil pan, but yep it does screw directly into several of the main bearing caps)

Cool... I'll be curious to see how much this costs... the guy has 2 or 3 crank balancing machines and he does it for all the local shops... so he should be the best and the cheapest on this one.

I couldn't believe how much that crank weighed just by itself.. It's a small part in some ways and it weighs a massive amount!

 

[ddogg777]

Yes, that thing is friggin heavy!

 

[TurfBurn]

Well I have BUTT loads of pictures... since the blown up part is pretty covered... I'm going to make a new thread of "the rebuild" and try to include enough info so that people can benefit from reading the thread if they want to do it themselves. I'll try to add some more of the blown pictures here... but here is a good teaser for you..

 

[Brian MP5T]

Please Post a link to the new thread here so I can find it.

If you need any help, I had mine appart at 500 Km and built it up. Let me know. You seem to have a real good grasp on the whole thing, just an offer. Brian

Any help is always welcome. Everyone's overall opinion is better than just my ideas and thoughts... I'm pretty much going to throw the book and about 6K at this motor... so we'll see where it gets me!

there is the new thread.

Thanks!

dude...
I really have no way to describe this ...
Your motor got freakin destroyed..


The thing that really struck me was the upper oil pan, I thought it was very insane the amount of dings in it...it seriously look like you had a snap, and then that space acting as a freakin jiffy pop of metal chunks...unbelieveable..and to this we still have NO idea what caused this...

Mad props on throwing all that money and effort into the engine..I love the fact that your going to make a big thread about it...

Can we say Bryan Pendleton of protegemp3.com?

 

[TurfBurn]

Yeah it took a HELL of a beating... I'm quite sure the rod snapped... the rod had to be moving to hit the piston with enough force to shatter the skirt and so forth. I think it snapped up by the wrist pin, and then swept through the block and the upper pan and then finally came off after it beat the living daylights out of everything else!

I like posting a thread on what I'm doing because it is just that much more information that is easier to find and hopefully someone finds something new that spurs us on to even better engines and better performance!
