Think you guy's could take a look and tell me if this thing is salvageable, or just a expensive paper weight?
|
If you look you'll see that it looks like the rotor hit the side plate and it's also has a pretty good amount of blow-by around and past the side seals. I just don't know what came first the touching of the side housings or the blow by.
|
Both the plates and the rotors have blackened marking on them. I'm not sure what happened, but there was no signs of detenation when I drove it. Zero in fact. Motor was recently rebuild and clearanced with all seals. Stock turbo and electronics, only mild street porting done. I just don't know what happened? Anyone have any idea?
|
Lack of oil . Engine was about to seize or started to. The rotors are not salvageable. When the oil is not there to keep them cool they expand and the side seals are toast. The side plates may be beyond repair also , lapping them may save them but the hardening may have been damaged leaving only soft metal.
Best to find a new block. |
yep its toast
|
stick a fork in it, its done :(
|
Yeah, that seems to be the consenses from out here too. I think I'm done with these things. Had enough.
|
damn thats sucks.. it deffinatly looks like u need a new engine thats just gone!
|
Yeah I responed before with my freinds account, but ya pretty much sucks. I'm looking for a good S5 block. If anyone know of one please let me know.
|
that ****'ll buff out :p
|
Yeah I hear that, but listen try not to be so technical next time though.

About the best that can be kept out of this is the rotor housings, possibly. B |

Yeah I think we all agree on that, but what I'm curious about now is what caused the lack of oil and why? The motor was rebuild with all new internals including all new seals all new bearings and a new pump, but it seems that the problem started with coolant mixing with the oil, which then resulted in the failure you see now. I'm think it was this mixture of the coolant with the oil that did her in, so to speak. I could be wrong though. theres a freeze plug on the fron iron, almost the only way that can happen |
That's good i9fd3 and I will double check that, but I'm almost certain that was not missing when I opened it up.
