BHG removal

kewlcoconut · 01-29-2006, 10:53 AM

I searched the forum for a tutorial to change a BHG, but i couldnt really find one. I saw somewhere that someone wrote a step by step guide on what to take off and repair. but i cant seem to find it. I think im gonna do my HG myself, but I need a really good tutorial for a newbie like me. I havent tackled something this big before.

EDIT

forgot to mention that my supra is an NA. just so i dont get confused when it tells me to unplug something and i dont have it. lol.

Here you go. He says Cam position sensor, but it's really the distributor.

Dont forget about cygnus tsrm too.

you can do it !

take your time and mark all the nuts and bolts . hardest thing is pulling off the turbo's oil feed and water feed.from underneath the turbo if you have one that is .

well i have a few more questions about the HG. should i replace any other parts in the block when i do this? gaskets, any other misc. parts? i had a rod knock a few years ago, and i have a partial gasket set, i know i have the intake gasket that rests between the block and the intake. i was hoping i had a HG in the box, but no luck haha. any special tools that i would need to get certain parts out?

sorry for all the questions, i just wanna make sure im prepared and not run into a problem if i dont have a part or tool.

thanks, kyle

A regular tool box should be sufficient, mainly size 10, 12 and 14 mm sockets. You'll need some large hex keys for the head, my uncle custom made some cut from a huge hex nut. IT is crucial to properly clean all gasket surfaces but not to a degree that you scratch major grooves onto the metal. Make sure you sufficiently clean up the block surface (this is especially important). Get the head milled, replace all injector seals, replace any gaskets, make sure you achieve true TDC, and keep track of everything. Get a stock toyota HG, some ARP head bolts and you'll be good to go. I was basically a noob when I did mine, but now it runs great and I didn't have to pay over a G to get it done. Just takes time and patience.

This is a great learning experience. Find a freind and get to wrenching

Good luck.

I chose not to have a friend help and make it a true learning experience. I agree with changing the injector seals. I learned from not replacing them the 1st time around. They should be available as an injector gasket kit (each kit services one injector and should be no more than $6 a kit) available at most auto stores. Don't go to the dealer for injector seals, too much money for each gasket and o-ring. Replace hoses as necessary. Some may be dealer only, usually the ones with tight bends, like the 90 degree 3" heater hose on the back of the head ($20).

Pain in the ass items (not in any order):

1) ABS Sensor connected to the top of the tranny.
2) Installing the turbo oil line. (NA is NA[not applicable])
3) Installing the ground line to bottom of intake manifold
4) Install the lower half of the intake manifold before installing the head with the EGR valve too, or it will be a PIA.

I can't really think of anything else at the moment. It's not all too complicated, just takes a little know how, and some time and patience.
