Under plenum maintenance...................

[Z51JEFF]

Ive got the plenum off for injector replacement and before I get it back together what if any preventive maintenance should I look into?

Check out your Vaccum hoses, Spark Plugs wires & Coil Packs.

Don't forget to tighten oil box bolts.
Check, double check, check again, *ALL* vacuum fittings/lines/solenoids.
If you don't already have a vacuum tester, get down to your local parts store and buy one.
Check the PVC's and associated hosing, it's easier to get at with the plenum off.
For some odd reason, mice seem to love to take up residence under the plenum. Be on the lookout for nesting material down around the starter.

Ive got new coils and plug wires going in.Would it be wise to coat all rubber fittings aswell as all vacuum lines with some Krytox.Id hate to put something on these soft parts with the intension of preserving them only destroy the parts in the process.

I posted on the other forum, Glad you have the coils dont forget cleaning out the drain hole and a stainless bolt upgrade.

Check all of the injector housing bolts. When I pulled mine for porting I discovered that the inside row on both sides were finger tight. I understand this is not uncommon. While I was under the plenum I took small plastic wire ties to secure all the vacuum lines.

Change the serpentine belt if it needs it or you don't know the last time it was replaced!

I totally agree with what Tom said about. Take everything off to look at the starter (down below the coils). Then remove the starter and clean out the drain hole. Best of luck!
