Alright, TB, LIM and SC are all cleaned up and ready to go. Gasket surfaces are nice and clean. I am still miffed that someone didn't put a TB gasket on and used gasket sealer. The TB was so dirty, it took me 45 minutes to get it nice and clean.

I forgot to say that a sure sign the LIM gaskets were shot is when I took off my oil cap, it wanted to stall, but managed to regained itself.

You sure that isn't a sign of needing a new PCV?

Sounds like the "dealer" who did the original replacement had a crappy mechanic and no quality control.

Anyway, looks like you are doing it right this time. Are you using the newer aluminum framed LIM gaskets?

hmmm....no? The dealer had the plastic ones, Autozone didn't have them (like always), Advance had the plastic ones, Napa had plastics but were out of stock, so I went to federated and picked up a set of the Fel-Pro ones. I bet the dealer did do a crappy job, I bet they rushed it.

Question that is very important is...... What is the tightening sequence and what should I tighten them down to? I need this for the LIM, SC, and the TB. I just recently made a deal here on the forum to buy service manuals, but I haven't sent the check out yet.

No aluminum framed gaskets for Series 1. Use Fel-Pro or OEM.

Torque sequence should be a zig-zag. Torque in stages. Half torque zigzag, then 3/4 torque value zigzag, then full torque zigzag.

Sanding down the LIM is not good practice. It could cause vacuum leaks at idle and Boost leaks at WOT.

Alright cool, no sanding here, I'm really careful at what I did. So zigzag and do torquing in sequences... what should I tighten them down to?

EDIT - Found it in techinfo.

Crap.... my torque wrench doesn't read inch pounds. I'm guessing 89 in/lbs is 10 ft/lbs?
