it should be in the engine mechanical.

it suppose to pull out evenly, obviously will require some force, and also it will tap back in.

Get the pipe nice and hot then let it fully cool/shrink and it should come out.
Thats pressed in and not normally removed. Should have been left in the head
Is there any sign of a set screw underneath it? I am not familiar with this engine but the old Porsche water boxer engines used a bonded in pipe similar to this, they had to be heated to remove them.
They were prone to leaking, a different bonding agent and the addition of a set screw was the permanent fix.

I'm thinking an internal pipe wrench and some heat. It might be pressed in with Loctite on it.
Trav,
There is no screw underneath it. If I end up having to remove the pipe, do you know where I can purchase the bonding agent? I am guessing once I remove and reinstall it, it most probably will leak. Thanks!
Merkava_4,
Thank you. That looks like it will greatly reduce the chances of damaging the pipe when I try to remove it. I was thinking of using my hands while wearing thick work gloves. That idea was axed out completely as I will be putting a decent amount of heat to it. Hehe.

I've had good luck with a little heat and a slide hammer.
YMMV
Good luck

This is what I was thinking. How much could it be vs what is your time worth?

Check with Toyota parts dept at a dealer, if they look at you like you have 2 heads use Loctite 638, it works well for this sort of fitting.
Any word from the rebuilder? Did you find a new part?

I'm just a backyard mechanic, but I guess that if I tried to remove something like that, here's what I'd try.
1. Find some kind of wood dowel or similar (maybe long socket if you're lucky) that fits snugly inside the pipe to give it some internal support.
2. Run a vice grip on the outside and try to twist it to break it free.
3. While twisting, pull at the same time to inch it out.
Heat may be necessary (the hole in aluminum will increase in size more than the steel pipe will expand due to the difference in expansion rates). If you're throwing the old head away, then torch...
Good luck.

Skid,
Decided to have my nightly garage session and mess around a bit. Hot da*mn!!! Heated the aluminum section with my propane torch for about a minute on low and it came out without much effort. It was earily easy. Thank you!!
I used a Craftsman 3/8" drive 10 mm deep socket. The hex end of the socket had an outside diameter slightly larger than the internal diameter of the pipe. I decided to tap it in with a dead blow hammer.
Thank you very much to everyone for their suggestions!
