Removing turbo oil drain.

[Randee of the Redwoods]

The time has come for me to do things to my truck that shouldn't be done. One of those things involves swapping the GM8 turbo I have laying around. BUT, after fooling with the turbo oil drain block piece, I had a good look at the areas I'd be working in. Can the turbo be taken off with the drain tube in place? How hard is it to get to the 2 bolts from underneath if it has to come off before the turbo can come off? How hard is it to get to the turbo bolts themselves? Since this is a Texas truck, I haven't had too much trouble on any of the bolts. Nice dry life has made them very compliant so far.

When I had the turbo off mine, I left the return plate on the block. I don't remember it I took it apart at the hose or if I took out the 2 bolts on the turbo though.

i just replaced my GM4, and it was not tough to get to the two bolts under the center section. I also discovered that even with 180k miles, all of the bolts and nuts came out with no trouble. that would never happen on a gasser with equal miles.

you will probably need a new oil drain gasket, mine was stuck, and it tore.

It's not to hard to remove the two bolts(10mm), it can be tuff if you have big hand, but it's doable.
The turbo is a diffent story there are four bolts that connect the turbo to the exhast manifold(15mm, i think)These are a little more of a pain in the ass. It easier if you remove the water splash guard from the fender well. Then it is a little easier to get to them. I used a large extenison and swivle. Also could use a reg. wrench on the to inboard bolts(closet to the engine).
Just pry that someone was kind enough to use antiseze on the install.
Hope this helps a little.
Good luck

My 92 has a GM1. What are the advantages of the GM8?

Supposedly the GM 8 flows better due to a relocated wastegate.
