PHH: Replacement vs By-Pass. My Thoughts. (1 Viewer)

[AlaskanLX450]

For 'side of road serviceability' I opted for the Around the Booster bypass. Quick and simple, and even after completing the bypass and getting the oppotunity to re-do the PHH again a month later by means of head gasket, I would do it again.
Its been beaten stupid off road, there are no signs of abrasion or deterioration of the hose or booster, and if any problems do come about, its a quick easy repair with just hose and clamps. Plus, IMHO the hose is much easier to get to, remove and reinstall on the head by it self.

i did the bypass and went around the brake booster so that id have a little extra hose just in case something happened to one the the ends ie cracked or damaged. i also used the constant torque clamps.

Ditto. Came as a kit.

I have a 1997 lx450 do I need to do the bypass hose thing to my year also . Would some one tell me if there is any differences from year to year in things around the motor or is every thing the same from 94 to 97 . Is there a video of someone doing the by pass . I have had my 2 450's for 2 years and haven't done any thing to the motor or surrounding parts . Would some one list the things I need to change or do right away before I find out the hard way . Thanks Steve

Pretty sure all the 1FZFE engines have the PHH and should be done in the comfort of your garage/home/driveway and not on the trail (not that it is impossible, just makes things easier) IMHO

However whether you choose to bypass or not is up to you.

Is a bypass still the best way to go or have things changed in the hose world and the addition of some kind of heat wrap so I can just change the hose and not do a bypass. I watched this video and it looks like its a good fix with a silicone hose with what looks like good clamps . And I was thinking with that and a heat insulated wrap clamped around that ,that it might last . Or does doing the bypass the best thing to do . If your doing a bypass are you plugging that pipe that your taking the hose off of and connecting it somewhere else.

yep. bypass is where its at. less points of failure. 2 clamps and 1 hose vs, multiple clamps, hose, and metal tubing. its like using a piece of 2, 3, and 4" wires, and butt connectecting them together to get one 10" piece of wire...doesnt make sense.

AMEN MY BROTHER....lol. I am with you on this,,,, I got very creative with my setup and looks professional making custom brackets along the way ,, many compliments on it. That OEM setup is way to involved for just one hose,, especially in my case removing the entire heater core, valve, pipes, octopus of hoses and clamps, etc ,,, and routed it right back into the thermostat housing ,,, made a custom aluminum bridge with custom brackets,,,,,over the valve cover,, sounds wild ,, but looks professional .... Everyone is different on how they do things in life,,, I like keeping things simple and adding a twist to it,,,,lol. No pics ,,,sorry,,,, money has been going to all the other Toyota OEM Parts,

No need to bypass around the booster, if you really wanna get crazy, just protect the line with some sheathing-like wire loom conduit. Seems to me that leaving the hardline in place would be a good idea. If you ever rupture the hose for whatever reason, you could use 2 smaller pieces cut off of the ruptured line (and the original hardline) to limp out of wherever you are...given you have some extra hose clamps in waiting. System redundancy.

Don't forget to use constant torque clamps with this stuff.

Very nice and creative,,,,,

No need to protect silicon hoses from heat........whole reason for silicon is they tolerate high heat for a very long time. My silicon hose bypass will mostly definitely outlive my 80.

Constant torque clamp isn't really needed either as long as the inside of the clamp is lined so it won't cut the softer silicon.

If having a long piece of hose flopping around was a good idea, it would have come from the factory like that.

What size is the inside diameter of the green hose you used and how many feet do I need to get .
