Howdy All!

2006, 135K mi...Recently, I have noticed the motor is getting loud, only from 2100 to 2250 RPM. Runs like a kitten, pulls hard sounds great, except at the mentioned RPM. It is like a switch, it comes on consistently and goes off consistently, if you hold it at 2200 it will continue to make the metallic diesel sound. I thought it might be the VVT engagement, if it is the tensioners, I hope I can wait till the warmer weather to change.

Looking for input, any and all is appreciated.

Might be a heat shield on the exhaust. I think it's a fairly common issue. Mine makes a metallic rattle at about that RPM as well, pretty sure it's a heat shield I've yet to dig around and find.

Thanks Airmap!

Have removed most of the exhaust shields, thanks to salt, cats and new exhaust, this is more associated with engine, I was hoping it was VVT solenoid but I think it would thro a P0011 if that were the case, I got no codes now. ???

thanks,
frosty
