What he said x2..:iagree:

Well thats it . I blew the engine ... probably due to oil starvation during a spin doing some left and right then tank slapper doing a 360.

Mr. Baker sent me a text about this last night! Bad news man....

Are you taking it in for an estimate for rebuild? Was there a catastrophic failure/piston out the wall of the engine type thing or just a dead engine?.....

Maybe a good time to think about a built motor! Sorry dude. Blown motor sucks....

so are you gonna rebuild a new motor?

Im gonna try to pass it under warranty , there is a new dealership here in town and im sure they wont accept the car .

my next bet is to put the car back completly stock as much as I can and Tow the car to another dealership where I went the last year for a new tranny under warranty (7AT).

if that doesnt work ...

There is a few option there and there

- rebuilt the short block and install my old spare Engine HR head with big cam !
- Get a used long block somewhere

if nothing is possible
maybe an engine swap for a lighter one ?

Sorry to read that. Hopefully you get it sorted out in no time.

Sucks to hear. Go for the HR head swap to ditch the VVEL! Thats what all of the Grand-Am/World Challenge 370Z teams ended up doing.

Im thinking about this but im not sure how to make everything work together.
the problem with this is that my 370z came with the 7AT ...
I would also need to swap the tranny if I go with the HR ECU since it was mounted with a 6MT ...

I do have the whole HR engine /6MT tranny w/shifter / wiring harness / ECU


I would need the pedal assemby / Clutch master cylinder for the HR tranny / clucth hose line / and some other stuff that I am missing.


also its been a bit more than 3 years that the spare HR engine/tranny didnt run ...

A few guys already know that I blew my engine at my last Time Attack.
this is some update from my diagnostic .

I towed it back from the dealership last saturday so I started right away to remove everthing in front of the engine to have a full acces to the front .

I removed both cam cover to look at the chain since I suspected a broken or loose chain .
the driver side chain that connect both Intake and exhaust cam was quite loose to compare with the passenger side !
until I compare them side by side , I suspect one of them elongated !

next step was to remove the driver valve cover to see what went wrong in the end where the knocking was comming from in the beginning while the engine was still running porly



Located at piston#6 ,, look alright and wet from the oil... not much sign of any defects.

located on piston#2

you can see the dried VVEL camshaft and the broken pawl , VVEL valve from piston #2

side holding pin pawl getting out !!!! ,, VVEL valve from piston #4 , the dried up VVEL is due to an extreme heat generated by the lack or lubrification !

soo after this ... my conclusion would be
do not rev up to 8000 rpm !! and avoid taking corner at 1.35-1.4G

Sorry to hear about the engine man. I really hope everything works out and let us know how it goes at the dealer!

no warranty...

Ouch. What's the contingency plan? Any plans to contest ?

its hard to contest agaisnt picture showing every mod you have done .....
like I said the new dealership lack experience and went way to fast in their procedure and she agreed with me..
she really wanted to have the job (manager) that would have gave some hand on experience also to their tech ! ..

too bad they failed

a quick update on this ..

I got a complete HR engine in my basement now ! :)

the VHR engine should be removed from the Z next weekend and will be deeply inspected.

Sorry about your engine. This is an amazing journal though, hope the rebuild goes well! Keep us posted!
