I'm assuming I use the same intake to the manifold for the NA8 as showned on this NB photo?

that's an NA but with crinkle coated cam cover

Oh yeah, Andrew, which hole did you use to put the cleaner through?

The one that goes to the brake booster

Make sure you post a video as well :mrgreen:

Hmmm... I don't know which one that is :oops:

I'll try and remember to do some video. I'm currently without camera, and the camera on the phone is rather rubbish.

Cool, thanks :mrgreen:

I suppose it's 50/50 really isn't it?

These two locations are also good, right after the throttle body. Probably end up with a better amount of the cleaner to the individual cylinders & more of the intake manifold will get cleaned too.

Throttle body cleaner spray also will do the same job as the Subaru stuff.

If you want to also while the engine is off, take the intake pipe from the throttle body off, open the throttle plate and spray the entire inside of the manifold. Let it sit for minutes and then startup the car.

Couldn't that cause hydrologic lock and bend pistons/valves? I thought the engine had to be running so this stuff turns to steam.

From green_comet's first post

green_comet wrote:These are the instructions on the can, bring the car up to running temp, then turn it off.
Spray half of the can into one of the lines going to the manifold.
Let it sit for about 5-10min, and start it up.
It'll run like crap so keep the revs high, so it doesn't stall.
When the car is running alright and most of the smoke has cleared, unplug that same vacuum line again and empty the other half of the can into the manifold with the car running.
Make sure to keep the revs high or it will die doing this.
Once the can is empty turn off the car, and let sit for another 10min.
Then start it up for more smokey action.
Then once its running clear go for a 15min drive.

I haven't used it but I believe it is a foam, therefore very unlikely to cause a hydraulic lock.

yeah its a foam, and I have never had a problem with it, even when pulling the plugs out and spraying it directly onto the tops of the pistons.

The instructions on the can say warm the engine up then shut it off, and spray half the can in. Then start the motor and spray the rest in while its running. I just spray the first half through the throttle body with a torch so I can see, that way I make sure the foam is coating the whole inside of the manifold.

Hmmm... just did this, and it seems like the car's idle has increased. It now sits on 1000rpm instead of the usual 800/850 mark. Did anyone else get this when they did theirs?

Also, I couldn't get those damned metal L tube sections off to get directly at the throttle body.

So long as it goes down eventually I don't mind, because it means it's done something. It doesn't surprise me that it went up. It just surprises me that after about a 15-20 minute drive it hasn't gone down.
