Need some help guys. I just had work done to my car at victor research in CT. They installed, magnus,hks cams,springs/retainers, and headstuds. I am not saying its there falut, but it might be. I got the car back sat, put around 150 miles on it. This morning on my way to school driving normal(50mph) hear a bang, i was like there's my engine. Got it pulled over and jacked it up, i saw a small hole on the front side of the block, but no oil from there, all from the back, so i assume there is a big one there. And this is weird the starter braket broke, atleast i think thats what it is. Timing belt looks fine, it would of snapped it it was off a degree right? So what could the casue be???


Thanks

That was sorta my point, if you didn't have any tunning done or a "stock" tune pre cams, then not knocking after cams wouldn't seem out of the norm to me. Now if you did infact have a good/proper tune, the cams or increased VE/airflow from the intake (or in your case head work) should be enough to cause a tune that wasn't knocking pre cams to knock. Abvoiusly the stock"tune" isn't really a tune at all, its pig rich & low on timing, this is less then ideal but like you said may allow you to add cams or other mods to increase VE & still be fine. Also if your not running higher boost/starting to push the limits of pump gas, this won't be an issue either (I just automatically assume that by the time you upgrade cams, your running 20+ psi )

I'm still running stock boost for now unfortunately, but my car does run veeeery rich (like you said). Thanks for the information and for explaining some things that I didn't quite understand, I really do appreciate learning about my car through others' experience, it saves me hell.
