man this is sure dangerous, today i start my car and as always when it's cold it starts like **** and shakes hard also it smelled like fumes so i get out and check under the hood and im looking around and seen little drops of see through liquid that is dripping down by some little cap by the throttle cable

is it hard to replace?

WAYNE88N/A

on the front of the engine intake mainifold or the back? throttle cable's on the back (86-86 n/a's, anyway)

check your pulsation damper.

dewey

Akabane

its the primary delivery pipe it's like by the thermostat area

WAYNE88N/A

yep, sounds like a PD- lots of rx7"s have died an early death because of that (hint- CHANGE IT!)

Akabane

thanks much, do you guys have any tips for me on this? what should i take off? the manifold,intake, and dynamic chamber?

yeah thats where it's coming out of

totallimmortal

Change that pulsation damper now please no one wants there car on fire

Akabane

doing so now but it's taking me a while to take off the throttle body im a newb at mechanics but slowly learning any tips are appreciated thanks again guys

10 & 12mm sockets, 1/4 and 3/8 drive ratchets, 6'' extensions, offset needle nose pliers for the hose clamps, some rtv if ya don't have new gaskets, small 90 degree pick/ or/ dental pick for the electrical connector clips, new o-rings for the injectors (if desired), new PD, new PD seals (2), clean out or block off EGR valve while you're in there, clean throttle plates while ya got it apart, think it's 3/4, 7/8 somethin like that end wrench for the PD, I know I'm forgetting something, just did this 3 weeks ago though...

You'll need to take off the intercooler (if you have one), and the upperintake/throttle body (leave those in one piece so it's easier. There will be a coolant hose underneath your upper intake, and a ton of vacuum hosing and a brake booster. Don't confuse the brake booster with the coolant hose, they're both close to the bottom but the coolant hose is underneath completely. Search for Pulsation Dampener and you'll get a lot of stuff. Be prepared for it to take a long time, go get some 5/32" vacuum hosing to replace all the brittle hoses you'll have there and it will save you some time later in life. Don't be afraid to stick a screwdriver under the U's in the upper intake manifold to pry the piece up. It will be practically cemented on there after the roughly 17 years its been on. Some bolts may be hard to get off, be patient use a lot of force (higher torque ratchets maybe) and try using Rust Eater spray. It helped me get all of mine off.
if you need more help PM or email me.

that sucks wish they had a recall and fix it? is there any recalls on this car?

Raymr

After a few times you can have the UIM off in like 20 minutes or so.

Raymr

Theres also a good fix for the EGR valve if its brittle, and you need it for emissions.

Akabane

well i just took off the throttle body took me forever from inspecting hoses and being aware of what i should take off next is the dynamic chamber huh

AusTexRex

Did you take off the throttle body AND upper intake manifold in one piece? If you did, you'll be able to change out your pulsation dampener from there. It is on the end of your fuel rail. It is a hollow screw with a plastic piece on the end. Email me if you need pictures or more advice.

BTW it took me about 6 hours start to finish. But that is due to some.. unusual circumstances of trying to get a single bolt off for an hour straight, and dis/re-assembling twice because I forgot to connect the brake booster and I couldn't get it on, the thing is a huge pain in the #($ to me. It broke the second time, had to replace it.. ugh.

Akabane

well i took off the throttle body but don't i have to take off the dynamic chamber? so i just have to take off the upper manifold with the dynamic chamber and throttle body all together?

Amur_

If you plan on getting at the goodies beneath, YES.

Akabane

im just stuck on trying to take off the dynamic chamber and manifold i don't know where to begin removing i was also reading that i can take off the dynamic chamber and manifold off as one?
