Torque the bolts - inside, then outside - 5nm and then 10nm.

To clean you can wet a rag with carb/tb cleaner to sop up the oil deposits. Then spray with the same, covering the tb's if you're spraying a bunch.

Can someone confirm the torque specs on the Plenum bolts?

I see 5nm and 10 nm but my Craftsman 44595 torque wrench cant do anything lower than 20 ft pounds (and 10 nm equals 7.3 ft pounds)

I have been looking for a vacuum leak and found that my plenum bolts were only 1/2 turn tight from hand tight

That's correct - see attached TIS info...

THe specs are right,
Although it is highly unlikely that you are getting significant (if any) leak in a naturally aspirated engine.

Invest in a 1/4" drive click type torque wrench that's rated inch/lb for fine granularity. Your engine/aluminum block will thank you for it.

Interesting they don't have a torque # in there for the funnel nuts. I was going to ask in one of the valve cover threads, but I guess if it's not in this document then it doesn't exist. I'm sure I'll figure it out when I'm in there.

You wanna laugh? When I did my oil pan bolt hole repair (see sig.) I used this to put the lower pan back on. A good one of these lower-value units is pretty pricey. Didn't think I'd need it again so I went cheap. Looks like I was wrong.

The funnel nuts are self-locking nuts, but may have lost their locking capability if they have been on and off a few times. So you can either buy new nuts or use blue Loctite thread locker on them and just snug them up.

Damp a rag with a degreaser/brake cleaner and wipe it down, also spray the oil separators to get all the caked up oil out of there. Might as well check under the plenum for vacuum leaks and clean the idle control valve as well.

I should probably do this when I do my valve cover gaskets. Is there a DIY for this cleaning or is it a no brainer?

I should be replacing my valve cover gaskets this weekend. How exactly do you clean this thing?
