Will The 1FZFE Run Without Intake Hose On

[turbocruiser]

Sorry, no real results after searching, but, will a 1FZFE engine run without the air intake hose attached from the air filter area to the throttle body? The reason I would want to do this is to be able to shoot some spray of BG air intake cleaner into the throttle body and intake plenum while the engine is on and while I work the throttle. I know on my 4Runner, without the intake hose on, the engine wont run without the signal from the mass airflow sensor and/or other sensors. Is this the same thing with the 1FZFE? If not, and if the engine would run, what about doing this with the turbo that I have? IOW, since without the intake hose attached the turbo will still pull air from the air cleaner area through the intercooler and then through the now open ducting up to the air intake hose, would it hurt to run the engine for a few minutes while shooting some spray through like this? Thanks.

can't you just spray it in the airfilter box (w/o filter), should get there?

or look for a vaccuum hose?

The engine will not run with the air intake hose disconnected........ for the same reasons your 4 Runner wouldn't run....... the mass air meter, etc....

Intake Cleaner can be introduce into the intake through the PVC hose while the engine is running, but that doesn't clean the throttle body. The throttle body will have to be removed from the intake to thoroughly clean it...... that's not a difficult task either.

What about threading and tapping an area after the air filter area, and after the intercooler but ahead of the throttle body where you could spray the intake cleaner through while the engine is running? I would not want to spray through the air filter area as that would take the product through the intercooler and I would not want to do that. On the safari system there is the aluminum intake tube that takes the place of the rubber air intake hose on stock engines. I could thread and tap there, or, I could just drill a super small hole in the 3 inch long rubber sleeve that attaches the intake tube with the throttle body, afterwards I could just screw in a screw to seal that spot. Any ideas, what I'm looking for here is a permanent way to preventatively clean the throttle body and the intake plenum without removing those things and without the typical soaking spray method? Thanks.

Sounds like a lot more work than just removing the TB and cleaning it.

Yes it is, once, but from then on it is a lot less work especially when you consider how much time it takes to totally remove the intake plenum and clean it and it is even less time when you consider how much more time it takes to then remove the lower runs of the intake plenum that go to the head. Think about it, if this would work, we could all introduce air intake cleaner at will and clean everything right into the combustion chamber, from there we could let the BG stuff or the Redline stuff clean it the rest of the way out. Too cool, and, perhaps too good to be true, I'm just trying to think this through to see if it would work.

yup, just drill a hole. You can just put a plastic plug in with minimal sealer, will suck it close; but screw and rubber washer is probably better.

or you could put a whistle in the hole and pretend it's a jet engine...

Cool, thanks E, with the whistle sound that already comes from the turbo and then another whistle added before the turbo, I could drive around goosing the throttle and making it sound like I was whistling at all the lovely ladies on the streets!!! Wheee, whoooo, wheee, whoooo. I'm sure I'd get another good date with Junk's moma!

Seriously, if this works though, it could save a lot of time with R&R of the TB and IP. I'll see how it works sometime soon probably. Thanks, i appreciate the advice.

If it were my project I would drill and tap a hole to acccept a 1/8 inch x 1/8 NPT brass hose nipple. You can slip a piece of 1/8 vacuum hose over it when you need to spray, and then use a black neoprene vacuum cap to cover the nipple afterwards.

This is a much more professional and satisfying approach then just drilling a hole somewhere and plugging it with a screw.

A 1/8 brass nipple will be impossible to find at NAPA or Pep Boys, but any decent hydraulic vendor will have it. Look up "Hose Couplinga and Fittings" or "Hydraulic Equipment" in your Yellow Pages. I needed a brass 1/8 tee for a boost gage install and they had plenty of 1/8 barbed fittings at my local hose shop.

Don't use a plastic fitting - they are too fragile.

John, thank you so much, this is an awesome idea and absolutely what I was wondering would work best. What I would really like to get is the 1/8 inch x 1/8 NPT brass hose nipple fitting where on the inside of the intake tube the fitting then bends 90 degrees so that I can "aim" the spray parallel to the intake tube and get more of it into the TB and IP in vapor form as opposed to squirting it into the tube in a perpendicular way, having it hit the opposite side of the tube and then lose some of the vapor into a pool of liquid. Do you know of any such fitting? Thanks again, that was awesome.

I think John's idea is good, providing you can find an appropriate place to drill and tap. You don't want to go thru a thin-walled portion of the intake runner

But I think the idea of putting TB cleaner thru the system this way is not going to be effective. You will never be able to properly clean the back side of the butterfly (where most of the gum tends to build up), nor will you be able to check and/or clean out the PER ports which also get clogged. Having done the "easy" TB cleaning this way, followed by an R&R cleaning a week later, I can attest to the fact that all I did by spraying cleaner down the TB throat was to make it pretty when looking down there. I don't think it did squat to remove any of the varnish and gum behind the butterfly--if for no other reason than that the butterfly protects the crap from the cleaner unless you happen to be running the TB cleaner in at WOT The PER ports are also behind the butterfly, so you won't see them.

I can appreciate how much of a PIA it would be to have to remove all the extra stuff, but if you don't service it properly/well, you'll never get the performance out of the Safari system the way it was intended.

Just my .02......

Scamper, some great thoughts, thanks.

The area I would likely thread through is the Safari intake tube which is at least 1/8 thick aluminum and probably pretty possible in terms of thickness required to hold a fitting that gets no great amount of force ever.

Your thought on the back of butterfly valve is probably super correct and also definitely something I did not think through myself. In fact, visually it would be super cool to see the vapor laden airstream flow over and under the top and bottom of the butterfly itself!!! Hey I know, clear acrylic throttle body!!! You are right that realistically wide open throttle would probably be the only way to totally treat the back of butterfly, especially with forced induction, that airstream would be so fine and forceful there is no way enough loose vapor would swirl and soak over the backside of the butterfly itself.

On the other hand, as long as it would not hurt anything at all, I would throttle the thing from almost closed to almost wide open throttle while just dumping that BG air intake cleaner in through the 1/8 fitting, this would work wonders most likely for cleaning the intake plenum and the intake runners that go to the head, in fact, it might clean them as well as removing those two pain in the ass pieces and cleaning em with parts washer. Perhaps a combination of removing the throttle body from time to time, and injecting cleaner through the fitting while throttling up and down, would be the best. Any other thoughts, I appreciate all of em!!!

keep it up

All I know is that you are giving me great info to think about as well as apply to my rig. All you 'cruiserheads' out there with turbo knowledge and experience please just keep it coming.

 

[CruisinGA]

Heres how I look at it-

My 1FZ-FE's have made it 100k and 110k respectively without ever having the TB removed. One of them is showing symptoms of a dirty TB, the other is not.

Remove the TB, clean it by hand, which will clean it better than any seafoam ever could, and you are good for another 75-100k miles. (not to say it shouldn't be done more often).

Yes, tapping and installing a brass nipple would make it easy to to clean most of the intake, but it wouldn't clean it as well as simply removing the TB and is more work.

It doesn't really hurt anything if the runners and plenum are dirty, and I bet they aren't. (The inside of the intake manifold on my '74 was spotless when I removed it for the first time probably since new).

It may help clean/decarbonize the head, like the polish part of a port and polish, but that is the only gain not attainable with a simple TB clean, and could be done just as well with an existing vacuum port or through PCV.

Yes its a neat idea, no it does not seem necessary.

But hey, its your truck, it won't do any harm, have at it-just be VERY careful tapping/screwing in that aluminum-1/8" thick is not much for a pipe fitting.

BTW that size nipple is avail. at home depot, or mcmaster.com.

It wasn't too tough to do it by hand by removing the TB. But your idea sounds interesting. I'm not sure how you would ever know if it was clean. I used Amsoil Super Foam FI cleaner the last time I did it. That stuff works awesome. It sticks to the sides and fills up the cavity. Then when you start it up it sucks it through. Doing it at full throttle with the Super Foam may or may not work because it might not have time to foam up prior to be sucked through.

 

[e9999]

that's a good point. Most cleaners you might want to leave on for a bit to work their magic. With sucking it in, it'll disappear right into the cylinders...
