Just a quick question to ask you guys, My friend has a 95 gsr, last weekend a strange meta scraping nosie started to appear. NOw every time he starts the car, it has a scrappin noise (metal against metal) comming from the block (driverside mostly) what could this be, (bad block?

 

Does the frequency increase with rpm? Wheel speed? Stays the same? Does it go away when the car is warmed up to normal operating temperatures?

 

Yes it gets louder as you rev the engine, and it does not go away once the engine runt o normal operating temperture

 

It gets louder, but does it get faster?

 

BUMP
i had that same problem and i never figure it out,
at idle no noise but when gas was given knocking noise was really loud
at first i thought it was the head so i changed it but it keept doing it,
i took the oil pan off and check if the rod bolts were tight everything was good but if anyone knows what this problem is let us know THANKS

im having a similar problem too.... its a loud clickin type of sound. as i rev the engine it increases and gets a bit louder at the pace of my revs... any ideas?

 

Loose valves perhaps?

 

it can be the valves i check them i thought it was the head and i changed it and it still did it, it has too be something with the block but dont know what it could be
