i was cruising yesterday nothing at all agressive shifting under 4 every time and as i am pulling into a parking lot i hear a weird noise. i get out and pop my hood and my car sounds like a deisel. i am not sure what is wrong the car gave no warning nothing just this sound like either i have a broken valve or i have a broken rod...

i have a crower head package.titanium valves/retainers and high rev valve springs,p&p and mild milling. i also have a gsr plate system(nos) but i havent hit it in weeks.the weird thing is just that she was driving fine earlier that day and now shiot...

anybody have any ideas..

 

rod or main bearings.. or valves needs adjusting

 

befor thinking the worst...as i did in my wifes volvo...check ur emission hoses..one may have come undone...when hers came undone the care ran like a broken down washing machine..sound familiar?

 

well, just hope it isn't as bad as my buddies engine. He just had the same thing happen to his LS engine. (Ironically he was on the way to the shop to get the compression checked out and about to get his Crower 404s P&P done, but not anymore).
Anyways he pulls over and his car sounds like a VW or Harely, or inbreed of the two. Rip apart the engine, two rod bearings, 1 spun crank bearing, 12 burntup/damaged valves, head was totally shot. Luckily block is still good. He is debating on getting a gsr engine or keeping his block and doing an LS/VTEC. He was going for a Nitrous built non vtec monster engine. I'm hoping he goes GSR so maybe I can get his block which is still good to go.

 

turns out that when i had the p&p and the crower package dont the shop didnt tighten the cam case bolts and it wating the calve cover to they tightened them up and off i went...no more cummings deisel in ,my eg...
