I'm getting ready to pull my intake off to replace the intake gaskets, which is letting me replace the fuel injectors, which is letting me replace the egr valve and all the gaskets for the plenum and runners and such. Now, knowing this... I have a set of felpro gaskets including runners, plenum, intake, fuel injector o rings and distributor. I have some questions about various parts I'll be removing and hope someone can answer some or all of them.

<This is a 1991 Trans Am, 305 TPI, F vin, all atock, etc>

First, there is a hose connected to the front of the intake/engine that goes to front/bottom of the throttle body. It has two weird screw clamps that are quite tall. I want to replace this hose as it just looks icky and those tall clamps are getting in my way. The question is...

What type of hose do I use to replace this? It looks like heater hose, but... Size and type if possible. Also, what kind of clamps should I use to replace those weird ones?
-----
Second... The fuel rail is coming off obviously.

Do I need any other gaskets/seals for the fuel rail, fuel pressure regulator, etc besides what I will have for the new injectors? The kit only has injector o rings, nothing else fuel rail related in there.

The o rings that came in the gasket kit... Will those also come with the new fuel injectors? If so, which should I use, or does it matter?
-----
Third... The distributor. From what I've read in 2 or 3 manuals and on here, I need to mark the distributor where it enters the engine. Mark it on the engine and on the distributor shaft and then mark the rotor before and after removing the distributor.

As long as I don't mess with the crank or try and turn the engine over, reinstalling the distributor with all the lines pointing in the same spots as when I pulled it out will guarantee it won't have screwed up timing, correct?

Also, once the distributor is out, can I turn the rotor or replace it and just set it back to the final mark I made and that will keep the timing the same?

Do I need any other gaskets/seals other than the blue distributor gasket that came with the set?
-----
Are there any other gaskets, seals, anything that I need to have on hand that the kit is missing? Like I said, I'm replacing the injectors, hose and clamps, all seals/gaskets down to the intake and the egr valve. The valve has a gasket in the box already too. Anything special I need to know?

 

Hose to TB is a coolant hose to add heat to the intake. Get a replacement hose at parts store and any standard clamp will work fine. On the fuel rail there is a special o-ring where the fuel hoses connect, good idea to replace these. Orange colored as I recall. Injectors should have o-rings with them, be careful with the locking rings on each injector, they rotate a bit and then the inj. comes out. Watch the heat sensor on the EGR valve, ceramic is easy to break. A replacement sensor is about 12 bucks at NAPA. Put some sealer on the intake lower bolt threads. Best to put engine on TDC and mark dist. and rotor carefully but you'll still have to reset with a light.

 

Alright, do you mean the 2 fuel lines that connect to the fuel rail or the line that connects the 2 halves of the fuel rail that has this o ring? For that fact, how would I go about getting new o rings? Meaning, do I just get an o ring kit and find one like it in it or do I give them a specific part name to get the exact one?

As for the timing... So, even if I don't touch or move anything, the timing will still need to be adjusted when I put the distributor back in, even if its at exactly the same spots as before?

 

great thread, as i will prolly be doing this project myself and i plan on putting lots of new gaskets in.

I was wondering the same exact question with the distributor cause someone told me i was gonna have to redo the timing in which i dont know how so ya...good thread nice info coming.

 

It's pretty sad... I have no problem replacing an axle, pulling off the intake, replacing a radiator, etc, but when it comes to timing, it's like someone dropped a nuclear reactor in my lap.

Yeah, I'm putting in every single gasket I can find from the bottom of the intake and up. After thinking about it, I'll be replacing the thermostat and that gasket as well...

Don't mind the next rambling paragraph. Just going on about a few things.

You know though, quite frankly, unless I'm incorrect here... This having nothing to do with the gaskets, but... People seem to have a hassle with the passenger front 2 intake to runner torx bolts... Since the intake is coming off and the runners only bolt to the intake, I see no reason to try and break my neck rerouting all the garbage on the passenger side of the engine just to remove those 2 bolts when I can take the intake out with the runners still attached and just remove it when it's outta the engine. Reinstalling it with either one or both runners attached. Not to mention that this all cam about cause I absolutely CANNOT remove the egr valve. I can't find a tool to get at that one bolt. Crows foot or anything just won't get at it. My tiny lil wrench will, except there's no room to get any grip with the fuel pressure regulator and the rail in the way. So I'm doing all this because of the egr valve. Well, initially it was because of the valve. Now I can replace the bad intake gasket and the 14 year old injectors, etc and possibly get rid of my poor acceleration problem with one of these repairs... Ok, done rambling now!

 

Did you get a kit with all these gaskets or what?

Where are you ordering them from and what kind?

 

Well, I initially asked for plenum gaskets. The guy came back with a long box that had 2 different throttle body gaskets, I guess for 2 different kinds. 6 runner/plenum gaskets, 1 distributor, 2 intake and 8 fuel injector o rings. Not sure if anything else is there, but I think that's it. It's a Felpro set. I will need more though, apparently. Such as the fuel line o rings, the thermostat gasket, prolly with the new thermostat. I just went into discount auto parts and asked when I went to get the egr solenoid, valve, etc. I believe there are kits with all that and a lot more for more comprehensive engine work. Headers, oil pan, timing cover, etc.

 

felpro does make complete engine kits but they can get a bit pricey especially if you dont need most of them, check the felpro website i believe they make smaller kits for cam changes an whatnot.

 

If im doing the intake gasket what other little stuff is handy to replace at the time of taking everything apart?

like EGR solenoid like you said right? its cheap right and is like a tuneup part?

What gaskets do i HAVE to replace from taking this all apart and what are some i should replace?

Intake Gasket / The Runner gaskets / Distributor Gasket?

is that the main ones?

Also what type of sealant? RTV stuff?

If someone can pm me some helpful tips and what not itll be appreciated.

 

I would go to NAPA and ask for a Gates 10777 hose for the little bypass hose. Standard hose clamps will work if you dislike the Weitek hose clamps.

 

Ah ha! I knew there was a specific hose for that. It didn't look like some regular hose. As for the clamps, it's not so much that I don't like them... They are easy to get at with the screws, however, it seriously gets in the way of the lower throttle body to intake bolt, plus these are showing their age and even though they work, are looking rust colored and 14 years old now. I'd hate to have one break off at some point due to age, rust, etc Hmmm, I might look into getting new ones of the existing clamps maybe. It's not like I have any great need to remove that hose frequently, so once it goes back on, it ought to be there for a long time. Not to mention again, that they are easier to remove and get at.

Thanks, yet again. You seem to have all the information I need. I THINK I'm about done asking qustions. Can't seem to find anything else I missed, so far. and now I have part numbers to boot.
