Okay, I have no idea why my car keeps ripping the boot of the cv axle and spraying grease everywhere. My car is low, real low. Does that have anything to do with it? I'm talking a few days pass and boom, grease on the walls of the engine bay.

Also, my idle is now at 1,500 steady. I bled the coolant, I don't have any vacuum leaks. No CEL. Before it would idle at 1,500, bled the coolant and fixed. But should I bleed it again?

Last thing, I notice the hose that goes from my PCV valve to the intake manifold, it's being like sucked. I took a pic of it. Is that normal? My buddy with the same car and motor does the same thing.

 

Replace that hose with a vacuum hose. That hose is old and softened so it's sucking in. Regular hoses are rated to handle pressure from the fluid being higher than ambient, so usually won't handle vacuum. Change the PCV valve there while you're at it.

 

Actually got a vacuum hose now and new PCV valve and it doesn't "suck". However, thy bucket is still idling at 1.5k.

 

adjust the idle screw on the TB simple over looked fix

 

Yep, first thing I checked. It's almost closed. Maybe like one more turn and a half and it'll be closed.

 

check for any VAC leaks.


As for the CV what brand of driveshaft are you using ? I've used part store ones before for tracking and they held up now the car sits about an inch above the ground with part store axels, mine are still intact. I have the DSS ones on standby tho make sure they aren't snagging on anything

 

Man, can you believe I had to replace both axles again today. Haha. Seriously, it's been a month. I'll be honest, I was cheap and bought remanufactured ones from autozone. But I have purchased these before with no problems! Question, what is the purpose of denting the axle nut when installing?

 

Another thing. I replaced the hose, it was working just fine and bam! The damn thing is sucking in again! *****. Any ideas?

 

Another thing. I replaced the hose for the PCV along with a new PCV valve as well. Noticed this morning that the damn hose is crap again and it's sucking the heck out of it. Any ideas?

 

So the nut doesn't come loose over time I always do it, it's like a cotter pin so to say at least function wise.




that's what it's supposed to do I'd be worried id it didn't, until WOT there is vac pressure in the ITM.


see pervious post^ that's what it's meant to do, yes it gums up the ITM but that's when catch can set up come into play. something HAS to be snagging the CV boot on you axel.

 

Outer boot or inner boot?

If outer, then quality of the boot is poor.

If inner, then you're forgetting to let air into the boot after installation.

When the shafts are newly-installed, are the inner boots puckered instead of being smoothly corrugated? If they are puckered, then lack of air is the problem. Aftermarket shafts are shipped with the plunge-joints fully compressed to save shipping space; you are meant to relax them on installation.

 

Agh, I completely forgot about these notifications. I want to say inner? The one that goes onto the transmission. I have never heard about the whole air thing. Basically, when I move the whole hub assembly to the side, boom, the axle basically snaps off, leaving just the part that goes into the transmission in place. I'm not sure if I'm making sense. All is good for now, if I happen to see another rip, I will post pics.

 

if adjusting the idle screw doesnt work there is a little diamond shaped metal plate with two screws holding it on and its on the backside of the intake manifold on the tb side. take that diamond shape plate off and there is a plastic circle thing with two knotches on it. tighten that down then put the cover back on. start it up and your idle should be lower. if not then it could be something else.

 

Isn't that the fitv?

 

Another thing, what I have understood is that the fitv works just until the car warms up. Once it's reached operating temperature doesn't the IACV take over? Correct me if I'm wrong. I took the IACV off, cleaned it well, installed it and now just idles at 1,250 most of the time.

Sometimes it'll idle perfect right under 1k but it's fluctuates I guess? Doesn't stay right under 1k permanently.

 

Completely forgot I had take this picture. This is my driver side that I just changed a few days ago. When I changed the passenger side it was just like this one pictured. I should add, the part that broke off, it was dry as hell, looked even a bit rusted. I know it sprayed the grease all over my firewall but I'm pretty sure it's not supposed to be dry at all. Any ideas?

 

is your IACV working? It seems like it isn't getting enough air and sucking that hose closed.

 

Yep, cleaned IACV and all is good. I ended up getting an "OEM" hose that comes from factory at the junkyard, the one all cars typically come with. Isn't sucking it anymore haha.

 

how low is your car? most likely your snagging the boot some how or your car is super low and putting tension on the boot but i still don't see how it would tear the boot. I have had bad experiences with axles from auto stores but i never had a boot rip. I just had my driver side boot rip but i think it was from being old.

 

This, you might have one loose + It might be your intake gasket that's cracked and leaks air... therefore the IACV tries to compensate by giving more fuel, hence a higher rpm.
I just had this same problem (Idle at 1500rpm) and came back from the garage... just a heads up.

 

I already went over my screw, my timing is advanced, can this be the problem? I doubt since just recently it has started the idle issue. It's really random, when my AC is on, it idles perfect (although I know idle will drop a bit once the compressor kicks on). I'll spray the intake manifold area tomorrow and see if idle changes. Thanks guys.

 

there's ALSO the TB butterfly stop screw no timing shouldn't do that it may bump you 100 rpms or so(mine did but pro1 cams).

 

Okay, how many screws are there? Isn't there just one? Lol

 

Do you have an fitv? Under the tb? If you do then it means the valve body has come loose interally

 

Haha. Oh okay, damn y'all just say FITV. I'm taking it off today and taking a look at it.
