95 4runner 3.0
I have a major water leak at the at the rear of the engine.It is coming from the #1 water bypass tube at the elbow that runs under the intake.I had a new hose on that tube but the metal tube must be rusted through. I can't keep water in her.It took me 3 hrs to go 25 miles home from work, had to stop about every 3 miles because I loose all the water.I had to wait for her to cool down then add more water and so on..... drive another 3 miles cool down and do it again.
I would like to know.... will I have to remove the entire intake to remove the tube?
this pic with the Red arrow pointing to the tube that has rusted out under the intake (really big hole)...I have removed a whole bunch of crap just to be able to see the darn tube but I don't want to remove the intake or timing belt and related components to replace that tube if I can avoid it....is there another way to replace that stikin water tube??? where does it go when it disappears under the intake?
any help will be appreciated

yoterr

wow, ur just not having any luck with this old yota huh? sorry i cant offer any help i dont have a 3slow

buckz6319

yoterr....thanks for at least replying....and your right no luck yet.....maybe there is a lesson to be learned here but I haven't figured it out yet, can the 3.slow really be this bad?..I know there is some good in her somewhere

You could try and cut it off down past the rust and run a long hose..... unless theres a line branching out... i can't really tell and never seen one of those rusted out....

to answer your question when the 3.0 is bad it's bad. Either you get a good one or you get a complete nightmare. I just hope you can sell it soon and acquire a 22re or whatever it is you're looking for.

pruney81....thanks for your input I appreciate it!...I wish I had a 22re, I wish I had a 22re....I wish.....but for now got to fix this one again so I'm going to keep on trucking....need to know if I have to remove the intake for sure,maybe someone will be able to answer that question and where does that hose go to?

I never tinker with my engine (no experience), but maybe you can get a diagram off of www.toyodiy.com ? Best of luck, looks likes its a frustrating task. Be patient and I'm sure you'll have it repaired in no time. Wish I knew what the hose was.

pruney81

judging by the pictures I would guess that you have to remove the intake to get enough of the hose exposed to cut a piece off and clamp a new one on there. (if that is your intention) Otherwise you could go to the dealership and get a whole new replacement hose, which might be the best way to go. They should have extensive parts diagrams there on the computer for you to peruse. good luck either way man.

^Yea Toyota will sell you just about anything so that won't be hard to buy...

pruney81

haha, point taken kiroshu, I was just trying to be helpful have you seen his threads on repairs he has done and his now for sale thread? It's a 3.0 nightmare...

What kind of clamp did you use to secure the hose? Are you 100% sure it is seeping out of the rusted part?

You can try to just move the hose down and reclamp it. Do this by litteraly kneeling on the engine. You will have bruised/cut hands, and you will get frustrated that you can't bend just a little bit more, but once its fixed you'll be so happy.

Here is a pic so you can see exactly where that line goes to.



Ok i suck and can't post pics. If you look in my picasa link in my sig you'll see where the line goes to.

thanks for all the advice...I have a block assembly pic from fsm but it just shows the tube going under the intake and disappears toward the front of the engine.I know for sure the tube its self has the hole, can't get to the location of the hole even to put on a longer rubber hose...I think maybe that tube is attached to the underside side of that intake

just pull the mani.... you got the plenum off already... and thats the hardest part! Just make sure u line up all the timing marks before u rip it out. While in there...I'd order a new pigtail wire for the knock sensor and replace that as well. U dont need new intake gaskets, just pull the rubber seals off the metal gaskets, and seal with fipg.

buckz6319

Well just what I thought the dam tube is under the intake I borrowed this pic from a member showing the #1 Water Bypass tube (Red Arrows).....well now is this a stealer ship item only?...I may be able to repair the tube? once I get my intake removed and the tube exposed so I can see where the hole is.

Kiroshu

Yea that seems to be a one tube assembly.... you can prolly order it over a fews days from a toyota dealer... its not going to be cheap.. i'm going to go ahead and estimate about 50-100$ for it.

buckz6319

yea your spot on with your price range....$87.00 and special order and $1200.00 labor!!..good thing I'm doing this myself......I did the timing belt a while back so this will not be to bad just sucks.

Team420

weird.... never seen one of those rusted out before!

I bet toyota red wasnt used that truck for a period of time.

I had this exact hose rust out on my donor engine when I replaced my 3vze. I did not know it leaked till I got everything back together and started it up.

I had to tear it all back down and replace the No.1 bypass.

Lucky for me I still had the old engine and just pulled the hardline off it. Did not cost me anything but time and gaskets. I would also reccomend changing the knock sensor pigtail while you are in there.
