I just unplugged the Pcv hose and sprayed in there..

Which is the middle thicker hose.

Did this last week. Took off the intake pipe, opened the butterfly and sprayed about half the cleaner into the manifold. Re-attached the intake pipe, waited 5-10mins, started her up and sprayed the rest through the three valves. There was some smoke, but not plums of it(will post a vid when I get a chance).

Car is definitely more responsive and pulls better. Though, the car is idling at about 1000rpm and had developed a slight stumble sometimes when taking off from 1st :evil:

I'll adjust the idle this w/e and see if things improve.

Overall, happy with the produc

My idle was out after I did mine too. At least you know it's definitely done something.

Is this stuff ok to use on cars with plastic inlet manifolds? I have a Mazda 6, figured i'd ask before putting it in.

i have to say this stuff is fantastic, before my engined died recently, it worked wonders, it revved a lot better through the gears and felt lighter and more responsive, if you can get your hands on it, buy it, i know i will be once i finish on this damn army exercise! :evil:

I just bought a can, $18.50. When it says "spray half", how do you know when it's approximately half? For example, under full press, how long did you let it spray for half a can? 30 seconds? 1 minute?

(Sorry for necro-ing this old thread, but I thought it was suitable)

Its not that important.

I have used many boxes of this over time.

Spray half the can into the manifold. Straight past the butterfly. Then turn the engine over. Dont start it. Just crank it once or twice to get some of the foam past the valves onto the piston crown.

Leave half hour then start and run at 2000rpm. Spray rest into pcv at 2000rpm.

So remove the intake piping and into the butterfly? Just to confirm, I spray it at the blue arrow, in the direction of the manifold or the pipe?

Yes, remove the piping. As for the arrow, cant say, im on a phone and cant view images.

Spray into the intake manifold via throttle body with the butterfly held open, & via the opening into the intake manifold where the PCV valve pipe attaches.

I used a can of this on my 245,000km NA8 a couple months ago. It made lots of smoke so I guess there was quite a bit of carbon build up in there. The engine now feels smoother (less vibration) and more eager to rev. I didn't have to adjust my idle RPM at all.

So my question is this...all that crap mystery go somewhere when it gets cleaned out. Does the cat catch all of that shite?

it gets shot out the arse !

zephyrus17 · Postby **zephyrus17** » Sat Jul 23, 2011 6:00 pm

Engine is so much smoother after the application!

But while revving it there was smoke coming out from the right of the engine! I guess there's a vaccum leak somewhere... :S
