Ok so this is my first post here and its going to make me look like a total noob but whatever, I'm freaking out and I need your help, and I guess I am a noob to the Z anyway so who cares. I have a 2003 Z and I picked up a new APS Tall Boy Plenum from one of the members here, I went to install it yesterday and it went pretty smooth other than taking a little longer than I thought it would. My problem is that the 4 small bolts that go on the inside of the plenum that replace the longer bolts that used to go through the cover of the stock plenum. I put them in only a few threads at first, thinking I would tighten down everything later but I got a little overexcited when I had the new plenum ready to mount and I forgot to tighten those 4 screws down at all. They are basically all like 3 threads down so not much at all, I started the car and actually drove like 12 miles to my house after. I'm at work today, obviously didn't take the Z after I remembered what I did so I'm going to go home after work and take the plenum back off and see if the 4 bolts are still there hopefully. My question is what happens if they're not there anymore and got sucked through the plenum? Am I completely f'd? Is there anything I can do as far as taking off the lower plenum or what? Please tell me I didn't just ruin my motor. Any help or advice would be greatly appreciated.

BTW I'm new to Z's but not speed or the care that goes along with it, I just made the switch back to 4 wheels from 2, had a 2005 Yamaha R1 that I sold not long ago so I got the Z to get my fix.

you'd know if one of the bolts got sucked in, it would make a loud noise. just take the plenum off carefully and tighten up the bolts to the specified torque. If there is a bolt missing than you're in trouble.

 

If you think lose parts may have gone down the intake runners, take off your lower plenum and look down the lower runners to see if anything is in there.

Dont risk your engine anymore without checking first.

 

If they are there, take them off an apply some loctite to the treads, them re-torque them down...

 

if you are taking Vo's advice, make sure you use the right application of loctite. They range from different ones.

 

Werd. Use the blue rated Loctite. It's medium strength. Do not use the red rated Loctite. You'll never get the bolts out again...

 

Well you can, but you might need an acetylene torch to heat them up
