Default Missing Something Here?

Did I miss something when I reassembled the intakes? Does anyone know what this thread is for? That's the throttle actuator on the right.

REWARD EXCELLENCE!

We need a close up and one farther away for anyone to get a reference to what the picture is showing.

Believe you forgot to install the sheet metal heat shield that covers the EGR passage. That passage goes from the EGR valve to the intake plenum for exhaust gas recirculation as needed. There are 2 inverted Torx bolts that fasten the heat shield down. Your photo shows one of the unused bolt holes.

Here's slightly back, with fuel lines visible (firewall passenger side). Does anyone have anything here on their L300?:

"Much ado about nothing." As GregS&L mentioned, a sheet metal guard is missing, covering the egr valve fitting to the intake manifold. Its cosmetic to hide the hideous (mine) rusted egr fitting from the pretty intake manifold paint.

I doubt the threaded part goes thru the intake to cause a vacuum leak but if you don't find the aluminized cover and Torx bolt, find a replacement bolt and screw it on, using a dab of loctite if you want to seal the threads. If there is a vacuum leak with the engine idling, put a finger over the threaded hole; a vacuum will suck your finger into the hole.

hmmm. I never removed anything that looked remotely like that, must have been the po. The hole does not go all the way through. I noticed a few photos of other similar engines with the same hole. I will ignore it for now.

Thanks
