hey how is it going everyone. new member here. ive got a 93 240sx ka24de and ive got a simple question. i have an ansawer but its kinda extreme. thought id check for some feed back. soooooo i went to take off my valve coveer off to replace a couple of items and the front two top bolts just spinnnnnnnnnn. any thoughts??? i kinda think ill have to just cut them off and replace them. also just put a custom intake (alumminum piping and silicone couplers) on the stock intake pass. side there is a hose connection under the stock hose. it leads to what appears to be the lower fan shroud . do i need to connect this or can i remove it. my goal is to remove as much of the clutter that i can.thanx

 

someone over torqued them beofe you got it. see if a vise grip can yank them out and helicoil those suckas. i believe thats a vacuum line for your radiator. prob best to keep it plugged in. someone correct me if im wrong.

 

The intake hose connection running down the left (from the front of the car) side goes to a resonator. Look at it from under the car and you should be able to see it. Take it out it's useless.

 

thanx for the speedy responce and i will take everyones advise
