Thanks PKRWUD. I'm printing this one for sure.

I'm pretty sure that it is the intake manifold. I torqued the bolts to 30 lbs., but they seem to have come loose after just a few miles. Looks like I need to be very careful with the aluminum to aluminum contacts. I had the same problem with the water pump bolts. Now I'm thinking that I really need to re-torque everything again just to be sure.

Thanks again for all your help.
