Is it possible?

Has anyone done it without pulling intake?

Never tried it, but I don't know how you could loosen the ISV bracket w/o having the intake off. It would probably make the job take longer than just removing the intake, IMO.

Pulling the intake is so easy ... c'mon

Leave the fuel rail attached to it and just undo the bolts to the cam tower. Along with all other attachment I can usually have it off (actually folded over the cam tower) in 5 minutes.

My mechanic took the intake off and the fuel rail and the injector wiring got all messed up he couldn't figure out what the problem was. He thought it was the computers but they were not. I also paid 5 hrs labour to fix the turbo oil feed because he had to take the fuel rail & intake off.

My new mechanic fixed the wiring problem but he also said if the intake get's pulled off again then 'all bets are off'

Maybe if you use a cutting torch....

If your mechanic has a problem with removing the intake manifold then you should have a problem with your mechanic...

What Chris said in regards to your "mechanic". It is less than a 5 minute job to get it off. I have had mine off several times with and without the fuel rail.

Yeah i have since moved to another mechanic... but the mechanic came highly recommended from rennlist. But I'm much happier with the new one.

****! sorry i was wrong i just went to check the invoice.... it was 6.5 hrs for changing belts, rollars, water pump, thermostat,all seals. It was 2 hrs for fixing oil leak at turbo, remove intake.

Bracket?

Hmmm. My ISV isn't full-on attached/bolted down to anything. The ISV itself has a bracket wrapped around it, and the bracket has these little rubber nubs on one side. Then, bolted to the block, is another bracket, also with rubber nubs on it. When the ISV is "in place", the two rubber nubs line up. From what I can tell, these separate nubs were never one nub at some point in time, they look like they're meant to be this way. The only thing that keeps the ISV in position is the ISV hoses themselves (sorta like the heater control valve.)

So at least on my car, if I pull/tug on the hoses, I can get the ISV out from under the intake manifold towards the front of the motor.

Jim: After more looking it appears that mine is in there "loose' also; just attached by hoses and not bolted down.

Hey Blown: well, I did not think about pulling with fuel rail still attached. that would make it a much easier job.

OmniGLH,
You're partially correct. The "nub" that you're referring to is a solid piece of rubber with studs on each end. If yours line up, it's because the rubber is broken. I don't have the part number in front of me, but they're about $5/ea from pelicanparts. Not that it will negatively affect the longevity of the ISV, but if you're in there it's worth the $10.

Luis de Prat

Yes.

I have.

It does require some patience and dexterity, but where there's a will, there's a way.

Really?

The nubs on both brackets look like they were intended to be separate. I mean, they're perfectly smooth, with perfect edges. It doesn't at all look like it's failed and just worn smooth.

I'm gonna have a look at the fiche diagrams... now I'm intrugued.

ramius665

They're called: Bonded Rubber Mounting (Idle Stabilizer) x2 928 110 191 10

The only reason I know that they are one piece: They were so burned up from the engine fire that I had to research WHAT they were to figure out how to replace them.

User 52121

Well I'll be!

Ok. I guess in the interim I can just try zip-tieing it down...
