Ok, well im taking on the removal of the intake manfold. Now Ive really never done anything like this. Do you think I should actually attempt this? Well I guess in all reality I have no options, dont have the money right now to bring it anywhere. Im smelling fuel underhood and I was told to look at the fuel pulsation dampener. Dont know what Im looking for, or how to know its bad when/if I find it.

So Im in need of some help. I REALLY dont want to screw something up, like I said, I dont have the money to fix it right now. Any links with step-by-step manafold removal would be great, and advise as to what to look for/watch out for. And any pics of where or what the fuel pulsation dampener looks like would be great. Im a little worried about doing this, but I think with the right info I can do it.

Also while Ive got the intake manafold off Im going to do a hose job, and info on that would be great too. If you can point me to good sillicone hoses that would be great. I know there are a BILLION options brands/size/color/will help you get chicks....Please make this easy on me. What do you use/have/recommend. Im a little pressed for time so I really dont want to go through the research that we all know and love. I just want to get the hoses on their way if I have to order them. Gotta get this done before the end of the week.

Well I really hope someone has some good info otherwise Im going to have to fly this one blind. Anyone in the FL area that wants to help me (doubt thats going to happen) Ill do the work and supply the beer, you just tell me what to do

 

Hey,

Check out Rob Robinette's site and www.scuderiaciriani.com. Both have lots of information on the vacuum hose job and on how to remove the manifold. The extension manifold is actually pretty easy and the vacuum hose job is more tedious than hard.

If you do a search for hoses on this forum you should come across all the available types of hose and the kits that are for sale.

I can't help on the fuel smell thing, but one important word of advise about the hose job: use a hobby knife to cut off the old, hardened hoses off the solenoid nipples, or they'll take the nipples off with the hose when you yank them off.

 

another word of advise. if your pressed for time, dont even start the hose job. im in the middle of it right now and its kicking my ***.

 

I highly recommend you either find someone in your area that knows what they are doing.. or leave it alone.. Once you get under that manifold.. **** stops working!!!

 

First, get the workshop manual free online so you can refer to descriptions and diagrams for procedures and part identification:

Here are two sources for silicon hoses:

Since you admitted you are "green" when it comes to working on cars, you need to realize that the FD is not a simple car to work on. The hose replacement process is time consuming and can easily be screwed-up. Doing the hoses when replacing the pulsation valve makes sense.

You need time, patience, tools, a place to work, and an alternative means of transportation while your FD is down, which could be for a few days. You better also have a fallback strategy in case you find the work too difficult or confusing. Do you have any friends experienced at working on cars? Have you located your nearest reputable RX7 repairman?

 

The nearest RX7 guru is (get this) about 45 seconds away. Nice guy, wears a rotor medalion (sp) on his chain. Knows his **** on first and second gens (his speciality) and is damn good with the 3rd. This is all good but he charges an arm and a ********. Normally Id bring my baby right to him. But like I said, money is not good right now. But he is the back up plan.

As far as technical friends, everyone is too damn busy to stop and lend a hand. (great folks around here) Thanks for the links. Im about to get started I think. Just starting to unbolt things.....so rewarding working on your own car, knowing that at anytime you could destroy it j/k

Oh...and what hose is better? I notice hosetecniques has a kit where as the barker one does not. Also if I went with the baker precision, how many Ft and what diamater do I need. I think im going to just go with the kit unless you should sudgest otherwise.

 

you will brake stuff

 

I don't see anything wrong with the kit from Hose Techniques. It might be a little more expensive than just buying by the foot.

There are three popular How-To web sites covering the FD3S vacuum hose replacement. Take a look at all three sites to find info on sources for hose, sizes of hose required, length of hose needed, gaskets that may be required, step by step instructions, and suggestions:

mindphrame, I just did this last weekend. Taking the manifold off is not a problem. The problem is to get to the fuel pulsation dampener you have to remove ALOT. Here is what I did.

1) remove tower bar, y-pipe, intake elbow, throttle body, extension manifold, vacuum chamber, throttle cables, throttle body coolant hoses. I also removed my intake to turbo hoses, intake box, airpump, to change my turbo coolant hoses.

2) to get to the fuel rail, you have to remove the solenoid rack. If you wish to do this, you can remove your alternator, and struggle with those pesky screws on the front and back of the rack (4 front 3 rear?) OR you can do as I did, I loosened my oil filler pipe, and removed my coils (only 4 bolts and a ground cable). Then if you can access the 5 bolts to the solenoid rack mounts. After these are removed you can bend the rail up far enough to remove the connectors/hoses to the solenoid rack.

3) there are 2 bolts and 2 screws holding the primary injectors/fuel pulsation dampener onto the block. before taking the fuel hoses off, make sure to release pressure from the system before. *Note* when you go to remove the fuel line in between the primary and secondary injectors, the hose on my car was now connected by a banjo bolt, not just a hose with squeze clamps like in the manual.

4) congratulations now you've removed your dampener. Just a side note my injectors were leaky, so I'm having them cleaned and balanced. I will also add new insulators and o-rings to my injectors when I get them back from RC.

I also just bought new vacuum hose from Baker Precision (great people to deal with), but I don't know if I should change them out after all. The stock hoses are actually in excellent condition, they have good flexibility and I have a perfect boost patern. I guess we'll see how adventurous I am this weekend. Let me know if you have any questions.

good luck,
eric

 

Are you talking about Carlos? The owner of Sport Compact Performance? I don't know where that place is, but the previous owner of my 7 said to go there when I need work on the car.

BTW, hang in there, man. You'll be glad you did.

 

Whew...intake manifold extention is off, not really a big deal. However, now that im looking back and seeing what was connected to that thing(!), I dont think I did a good enough job of lableing what and where everything is susposed to connect. Im really fearing that now. Other then that I think I about have this thing whipped. Also, while I had everything apart I decided to do the removal of the double throttle. Went smooth aside from the last screw in the butterfly. Had to drill that one out. Dont know really know the true benefit of this, but it seemed like one of thoes "While I'm here, what the hell." mods

I just ordered the hosetecniques kit. Hopefully this will arive in time. What a mess under there. I just touched one of the hoses on the vacuum chamber and it snapped off. Also in the process of getting the intake manifold off I think it hit another hard tube, It broke the plastic sylinoid off. Thats going to be fun, I dont know where it broke off from. Most of the hoses seem allright, but others just crumble to peices. Its going to be HARD getting to all thoes lil bastards. I am going to take the rack out and follow your process Hapa, thanks. I am smelling strong fuel smell after I got the manifold off, so hopefully I can track it down.

Jonski, yeah Carlos of Sport Compact Performance. Hes been nothing but great. Always been real cool. Even gave me a loaner AST for 2 or 3 weeks when I was waiting for the Pettit one (took longer then he was told) when it still wasnt there, he actually went to pettit, and picked one up then he stoped by my house to drop it off. Said just swing by when you can to pay me and drop off the other AST. Cool. He also put my radiator in, I needed him to put it in for warrenty. He does good work.

Well overall, lets see the #'s in round 1.
Busted nuckles: 2
Broken hoses : 2
Broken silinoids: 1
Coufused Looks : 14ish
Thoughts that Im going to need help getting it back together : Constant

 

Oh...also I think that I want to get my injectors cleaned. Wheres a good place to send them? Or do I have to find a local shop that will do them?

 

after i started and got the manny off i worked on getting 3-4 hoses off and already was like Fu%@!!! i have gone through about 5 exacto knives cuts from them all over my damn fingers from scaping and tryin to cut the hoses they are brittle and some are rock hard? i am just working on the ones i can reach and get out easy which are only like 10% of the hoses.......i cant really begin untill i get the damn rack off otherwise i will end up breakin all the solenoids underneath there...its not that bad its just very very time comsuming !! i am still trying to figure out how to get the y-pipe out is there anything underneath the car i have to get at to get the damn y-pipe out..


good luck!!!

 

If that's it, you're not doing to bad. Counting everything that was already broke and that I broke...
Busted knuckles: 6ish
Broken solenoids: 3
Disappearing bolts/screws: 3
Feeling/fear of never driving the car again: daily?
Confused Looks: just about everytime I look at something different
Broken tools: 2
I'm determined to get it back together though, I have the Mazda Manual and a few printouts from Rob Robinette's site also. I'm doing the turbo simplification that's on his site.

 

Whats this? I dont see that on the site. Is this something that I would want to do while Ive got this thing apart?

Anyway..good luck.

 

if you can read, have the right tools and plenty of time I chimp can do a hose job. be patient follow instructions and buy new toosl if needed. If you are like me and get impatient you start to break ****.

 

This is one place that a digital camera is worth its weight in gold....whenever I do a new to me project, I take digital pics of every step so that I have a photo history, and can see later if I had something in the wrong spot.....my pics have saved my *** a few times!
