So by looking at the pics, the problem is way bigger than anticipated. I feel your pain. The bright side is, now would be the perfect time to "crak" apart the engine and do internal upgrades.
Do you mind telling us how it happened? Were you driving it hard moments before or just happened out of the blue? I know you were showing your friend the car but how hard or easy were you on the throttle. |

So finally i got some good news the compression issue is now fixed the timing was thrown off really bad intake valves are all good but i cant see the exhaust valves fingers crossed they are okay! now as for the what caused the timing jump i have two theory's i know for sure that the the tensioner had something to do with it [Marked with the red arrow]. Now if you look at by bank two with the green arrow that cardboard type gasket blew out. Now i am not to sure what that is can anyone chime in on what that exactly is? in the youtube video the number one spark plug was out

So from 11 PSI went to 14.2 PSI. That much boost (relatively) is the cause of the failure? WOW, is incredible as what a few LBS of boost can do.
I had an Evolution a few years ago, and after installing HKS exhaust, air filter and a Profec B controller, the damn wastegate actuator went bad and I could easily hit 25 LBS of boost. My limits were set to 19 since I did not wanted to fry the turbo. Anyhow, I manage to stay away from heavy loads off boost (until wastegate was replaced) thus saving the turbo and possibly the engine. Since you mentioned the over boost, once you get everything back together take a look at your boost controller. I suggest a manual boost controller over a electronic unit. In some instances you can install a manual controller inside the cockpit so you can adjust on the go. I had two electronic units and both failed at one point or another. Good luck on the findings and repairs. |
Darn, lot of burgers in the oil pan.

Those are some big chunks to have flying around. I would start looking for a replacement engine

I hope this can help a bit (I know you are not doing such replacement but it can be beneficial at some point) http://www.the370z.com/diy-section-d...on-mounts.html
Search through the forum (especially on the DIY section) and you can find many removal projects, some with cool pics and details. The engine removal is just like any other car and that is.....disconnect/remove as you go along. I will post more links as I find them. I hope the link can help you since you are going to need a few extra hands/help. Are you doing it by yourself or do you have and can count on some friends? |

I was wondering how are things going with your engine rebuild or replacement. Any progress?
