Carnage carnage carnage.
OK so...I removed the engine + tore it down on monday. I found alot of neat things. Firstly, this guy.
I believe this is the what happened the night I finished tuning with the WI off. From what I can tell, this break was the miss I could feel in the engine afterwards. It still pulled great vac, and ran well with even (sounding...) pulses while cranking. Obviously it was doing SOME sealing as all the pieces were there, but there is evidence inside the break of combustion passing between my fancy new 3 piece design.
Here's another expanded view of it:
Then there was the actual broken seal that caused a pile of damage.
Thats one of the best housing fragging's of mine yet.
There was also a chunk of seal wedged in the one remaining apex seal on that rotor. But some did escape as my T04-R's turbine is a notchey version of its former self.
Also of interest:
This engine was a jspec I tore down, and refreshed. The engine had an easy life before as there was no evidence of anyone ever actually throttling the car. So much carbon that it had almost zero compression, but only because every seal was bunged up. As such, there was alot of weird browinish staining on the housings from combustion hanging aroudn where it shouldn't - and all those marks have cleared up now. There was also strange marks around the spark plug boss's (not the typical line/stain) that have lessened, but are still there only in a more "typical" fashion then before, I'm unsure how well the jacket mod has helped.
Also, there is pretty well zero compression getting by my first side seal fitting job, they look minty fresh!
My EGR weld-shut job has also stood up well, although some gases are still reaching the port under the exhaust port as there is a small amount of soot in there. I'll check out what else needs to be plugged.
So, another rotor, another housing, and a few apex's and this baby will be rocking again....two more weeks tops. Busy with house construction ATM
