lol... no, it doesn't.

 

They stopped buying locktite, this was gm's way to cut costs before they went bankrupt lol.

 

I had the same thing happen to me on a Ford 351 Windsor. Bolt backed out and then the pin sheared. I was like WTF?!?!?!

 

My cam pin fell out of my comp cam without the bolts loosening up. pulled the cover to add a bit more advance and the pin was just gone...

put a new pin in with loctite retaining compound...

 

This happened to me, but it was definitely my fault. My first time to dig into a motor in any way, I was doing my first cam swap. I loc-tited the threads on the cam bolts, but I never cleaned the oil off the bolts or out of the bolt holes in the cam. The loc-tite never cured.

I was lucky, though, as the bolts never sheared off. It did, however, do quite a number to the motor when the cam backed into the engine far enough for my BRAND NEW lifters to start hitting two lobes at once. The engine was complete trash at that point.

 

I have only heard of this happening one other time. Definitely a rare occurrence and costly.

 

We just had that happen not too long ago with one of the cars that I tune. It was not stock. As a result, I took the stock motor apart and put loctite on those bolts before I dropped it in my car.

What springs were you guys running?

 

PRC's at 155-160 on the seat. This was a while back too, and I have seen more so this. Especially the big hp turbo car that shift at low rpm's believe it or not. Car has been going strong for a while on the stock Lq9 at 825+whp, now on E85 too.

 

Never here also...
