Turbo BS Thread

Doing some welding in your combustion chambers???

 

Sorry. That was misleading. It is from my brother’s N2O LS1 that was making some funny noises

 

LOL he melted it good. Is he pulling enough timing when hes spraying??

 

Idk what his exact tune is. It’s one of those gm setups where they can tune the stock ecu somehow. Had had it dyno tunes for I think a 150shot

 

What it sounded like before he pulled the heads.

 

probably HP Tuners

 

Sounds like rod knock to me. Without being there to discern between top and bottom, it is a little more challenging to diagnose.

 

The aem one is just as good

 

If you missed it, start up in his thread..

Dakine beast yeah? Holy shit

 

That's what I was thinking too. He had read that it may be a bad lifter. He pulled the heads and took them to a shop to have everything checked and reassembled. He is debating on just pulling the rest of the motor out as well or just putting the heads back on and seeing what it does.

 

This is the part on the IAC that I suspected was causing low idle on cold start and rich afr’s and needed to be adjusted. This is the original the new one didn’t match up. I finally got a chance to adjust it today and it seems to have made a difference but we will see after I drive it some more.

 

Have him drain the oil and look for a lot of metal flakes.

 

I asked him just now. He said there was no metal in the oil.

 

Suction cup the piston crowns, pull up and down, and see if any rods have slop.

 

Thanks. I'll let him know

 

That motor sounded like a death metal song.

 

sounds like a collapsed lifter.

 

Thanks. I'll let him know what you said. He is supposed to take the heads to a local engine builder today. Is that something that they would be able to tell from disassembling them?
