Default loud tapping LOUDDD up to 3krpm.ENGINE IS RIPPED APART PLEASE HELP!

(972)302-0488 call me asap if anyone knows


after maxing out the car and then continuing home for the next 10 miles...(easy driving those 10 miles)we began to hear a slight ticking when continuing from a stop side.

WE PULLED THE F over.
*engine oil good(both sides of stick)

when you rev it up slowly, you can still hear how LOUD it is..even in neutral

-we have sandblasted worm gear and inside of piston on TCT about 3 weeks ago. made a big difference and alot smoother transitition it seemed like
-we have taken valve cover off and retainers do not seem to be cracked or broken
-valves were tight and loose so we set them back to spec. then we tried it again back to spec to reensure the work
-replaced tensioner pulley & belt on supercharger couple days back
-oil pressure fluctuates when warm from 42, 34, and later on from 12 , 0. it jumps back and forth so i know i need a new guage (this is @ idle; no boost)

im about to go back out and look inside the cylinders for fouling or damage and will also check spark plus to make sure they are not loose....


THE SOUND JUST SEEMS WAY TOOOOOOOO LOUD .... please help or give me a call

Didn't clean all the sand off well enough

Sand comes out

Sand goes into bearings

Bearings now spun

Your gauge isn't broken the bearings are what produce some pressure spun bearing=low to no pressure.

what does "maxing out the car and then continuing home for the next 10 miles" mean?
