i am going to be replacing the intake manifold gaskets, should i replace the PCV valve during this time ?

 

PCV valve is a $5 item. Just change it out.

 

Replacing the intake manifold gasket is a major job and why do you think it needs replacing??? PCV valve is a one minute job at most. Also your question containing these two items makes me wonder if you don't mean the EGR valve?????

 

its not that major of a job, jsut take your time and make sure you clean everything you see, it makes it look better as well, and make sure you buy the metal fuel line disconnect tool, i bought the cheap plastic ones, and they were not strong enough, that was the worst part for me, and making sure it goes straight on when re-assembling.

did you check out that page under shoebox they have a whole walkthrough of how to properly do it.

o and yea, you my as well change out all the valves you can, that way you know its all good.

 

well i know i need to have the gaskets changed because the intake manifold is leaking, i plan to replace the valves when i replace the valve cover gaskets

 

nothing to do with the intake gaskets but I have never had to relpace a PCV on a car of my own. my friends have had them clog and all I do is clean them out with WD-40 and they are good to go.

you can tell if it is bad by shaking it. if you hear nothing moving then you know it is clogged

 

Yes, just do it. $5 item .

 

a good bit of advice is to NOT use the front and rear gaskets. a bead of sealant work 100x better and has less chance of leaking. also replacing valve cover gaskets is a very easy job. replacing valves, on the other hand, is just short of a complete top end re-build. do you really know how much work is involved in that?

 

well my friend works at a shop near my house and he does most of the work on my car, he also has a firebird so he knows quite a bit about fbodies and LT1s, i dont think im gonna do the valves maybe later down the line when i put new heads in

 

well i just had the new intake gaskets put in as well as vacuum lines and it sounds mean even with the stock exhaust
