looks like spun a bearing to me...

I would say less than 1g assuming no machine work is required. That is cheap to me, may be not to you?

I would expect motor to need a new crank,possibly new rods and could even need a new block,main webbing has been known to crack if bearings weld themselves to the crank. Camshaft and lifters probably look torched too,could be bearing babbit welded to piston skirts from molten bearings splattering debri around.I wouldn't expect ANY part of it to cost less then a 1000$ except maybe the RxR,Smitty

BETTER, do NOT reuse that engine builder !!!!!!!!!!

AND believe me when i say i know what i am talking about.
Had an enginebuilder work onmy motor about 6 weeks ago and i am taking it out again for the second time after he did it.
I can hook you up with the right guy if you are sirius about NOT getting screwed.
To rebuild a complette engine should not take more then 4 days if parts are there.
Last guy who did mine put all wrong stuff in it.
NOW getting done wright for less what he robed me.

i would say that if you took that approach to fixing this then you know less than the guy that put it together in the first place.

That is some nasty looking oil. Looks like it got way too hot. For the next build, take some time to search and read a bunch of oil system threads. A lot of good information there. If you have a well designed oil system and a proper tune, you can run full throttle until the gas tank runs dry without hurting anything. Good luck.

Just got off the phone with the builder.. FULL WARRANTY !!!, sending both to him next week..

Dave, hope all goes well, just offer him thos suggestions I said about oil system, I bumped my pressures with new coolers and have no issues YET! 75psi cols, 40-50 after a good run, that seems to be helping me this time around. oil temps running hard 190-200 all the time!

as always, if you need any help I will do my best!

I would say if you conclude from some bronze in the oil filter and no spun bearings this is total destruction you are jumping to conclusions. I see one set of bearings, a polished crank, cooked block and all new gaskets. Any other conclusion from what is posted in this thread is ridiculous and most likely designed to line someones pockets.

Glad to hear the builder will take care of it for you DMC. You can see in this thread who not to ask for advise going forward unless you want to unload fort knox.

BT :cool:

I see both points... first off, Dave is a good friend and I am not and engine builder by trade, just for me..

I have had one hell of a season with similar issues, I wiped out mains 2 times this season, once on each engine, nobody in the world could give me a "perfect answer" I figured I had oiling issues, I pumped up my oil pressure and bought new cranks so they were not cut at all, I will tell you though... with the scrap Dave found I will pretty much gaurantee the crank needs cut, I have yet to ever have that much metal and was able to polish the crank.
even when cutting and repolishing a crank you are looking at 300 or so just for that.

I hope Dave gets fixed up, I know how many issues he has had in the past and this sucks for him, happens to all of us at some point but still sucks.

Dave... I would also talk to him about running coated bearings, that is another change I made, I have always done it with my car engines and the coating gives you a little extra room for issues, it acts as a film that the oil itself gives you, if you have a little less oil for any reason the coating will normally save you at least for a short time...

Like I said, Dave.. I will offer what i can!
