Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Idle dropping and bouncing??



Yes the paste is highly recommened. Helps keep the oil from wicking up and seals the LIM bolts down. LIM Bolt torque spec is 132 inch lbs. Convert that to ft lbs and you have 11 ft lbs. I did mine at 15 ft lbs cause I used the AC Delco metal gaskets.

Make sure you tighten the LIM bolts in sequence.

89 inch pounds is for the UIM, not LIM. Tighten in sequence as well.

So bolted the lim down to spec and in sequence but when i look at it i still feel like theres a little gap between the two is thus normal?

No it's not "cause GM". Many manufacturers use PCV valves. It's your responsibility to maintain your car properly. Just take it out and check it once a year.

Also I've used 4 different brands of PCV valves and the only one that has worked flawlessly is AC Delco.

He asked why the PCV puts oil in the LIM.
 
Yes i put on the side rubber seal then the gaskets and then rtvd where the side seals meet the gaskets so 4 places

So theres two hoses that become one at the throttle body and then one go to the evap pruge solenoid and the other goes to the top of the fuel pressure regulator. Does anyone have a part # for this? I tried to custom make one but its not working out well.
