I am about to replace both Rocker cover gaskets on my VG to fix a couple of oil leaks. Since I will need to remove the plenum, is there anything else I should think about changing while I am there? Obviously I will be installing new gaskets on the plenum, and i was thinking of replacing the rubber fuel hose between the fuel rails as it has never been done.
Is there anything else anyone can suggest? perhaps give the inside of the plenum a good clean? Should I replace the o-rings on the injectors, or should I leave them be if they aren’t leaking?

 

Clean the plenum and throttle body. Replace all hoses. Consider a tune up. Clean the MAF

 

and leave the injectors alone as long as they aren't having a problem

 

Definitely replace the fuel rail hoses.

 

-Plenum and upper intake manifold gasket
-EGR valve gasket (x2),Vacuum hoses (use cut to fit hose)
-Clean throttle body with carb cleaner and replace gasket
-adjust timing since you'll be pullin distributor off, screw making the rotor position
-Replace fuel injection hoses with fuel injection hoses (use NEW fuel injection CLAMPS)

 

What CM said.

 

y do u need two egr gaskets?

 

adapter to engine and adapter to EGR

 

Which do not have to be separated upon removal =only 1 gasket needed.

 

I'm doing this also this weekend. Gaskets, distributor, rotor, plugs and wires are waiting at Courtesy. Going to pick up on Sat. Figure I can just run to Autozone once everything is off and I see how much hose I might need.

So the EGR and adapter can come off as 1 piece?

 

yes, one piece..

 

Yea, but why not replace a gasket thats 2 bucks at most perhaps even a dollar at most...

Why cheap out on something that is perhaps original to save a buck or two? Not saying that its wrong but thats just me...I try to replace as much as I can when its cheap and I'm there.

 

In regards to the cut-to-fit hoses, how does others change CourtesyPart#11826 (the one that goes from PCV to firewall side rocker cover). I tried using largest hose I could find from Hardware store (which was actually heater hose).

What hose does everyone else use?

 

pcv to valve cover hose I had to get brand new from dealer as it was cracked badly. I paid 20 bucks locally for it. by replace vac hoses with cut to fit I was referring to all the tiny lil ones you'll have access to while everything is off. Just pull one by one and cut to that same measurement,

 

I understand your point, but the egr gaskets are metal based gaskets, the same as your head gaskets=very strong. They are very unlikely to ever fail considering the low pressure in this area. Don't get me wrong, I'm all for doing things right, but unnecessary is still unnecessary, no matter how you slice it.

 

you can re-use the gasket too as long as its not broke correct?

 

Once you break the seal on these gaskets, they are pretty much toast= replacement.
