Crower 264 cam broke? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

A little background on the situation. I had ordered Crower 264 cams for my s13 at the beginning of summer last year. I have the invoice of the order somewhere but cannot seem to find it at the moment. I ordered them and waited 2 months for them to be manufactured and shipped. During this waiting time I decided to buy a FP Big28 turbo, 550cc injectors, the cams, and a re-tune of my ecu. I received the cams, and other items, at the end of summer but did not have time to install anything.

Around December I finally get around to putting everything in. I fired the car up and it felt amazing. Nice sounding idle and smooth powerband. I let the car run for 10-15 in the garage, and reved it a few times; I was pumped. I shut her down and went inside. A few hours later I go out to take her for a spin when the car does not start. I try a few more times and still nothing. I am like whatever I will figure it out later on; being it was winter I just drove my jeep anyways.

Fast forward to today, I get to look at it and I am stumped. I pull the valve cover to find this....

Intake cam

WTF?
Little info
- I always follow a fsm RELIGIOUSLY
- I have installed cams 4 times and never had a hitch
- mechanical timing was PERFECT, I checked it 3 separate times
before starting the car the first time ( I hand spun the crank ten bajillion times)

I pulled the motor tonight and am pulling the head off tomorrow to see the damage (will update with pictures), and plan on contacting Crower on monday.

could have been a bad cast from the factory. give BC a call.

Ductile torsion failure. Something over torqued that shaft

Crower is not the same as Brian Crower.

Father/Son and two different companies.
