Lmm Turbo Removal/Install Tips.

So either tonight or tomorrow, i'm going to start pulling my turbo out and could use some tips. I also have to pull my inter cooler and clean that out as well.

Jack truck up, pull front tires, remove fender liner. Take the intake and mouthpiece off. Take the down-pipe off. Use a good 12 mm 12point socket for the up pipe bolts. You can get them through the wheel wells. Remove the up pipe bolts on the turbo with 12mm 12point. Remove oil line. Remove bolts that hold turbo to block.

you might be able to get that off by unhooking the glow plug controller (i'm pretty sure that's what that is) and snaking it out that way, but it's a MF to remove..

I just used a pneumatic saw, and cut it in half to remove it.

Don't forget about the coolant lines and I evacuated my ac to get the plumbing out of the way. And you can undo both upipes from the passenger side wheel well, the drivers side on the lmm is too tight to get your arm in. Becareful with the oil feed it has a banjo bolt fitting and the copper gasket can tear. Good luck.

This project defiantly sucks. I have about three hours in it so far, and I've got the down pipe heat shield out, trans dip stick tube out, Piping from the inter-cooler to the y bridge out, and that's about it. Going to hit it hard again tomorrow night. This would be 100 times easier if I just took the cab off.
I still have no idea what i'm doing with the whole egr delete. I bought a new down pipe and the egr delete from rick. Hopefully I'll have that mid next week and we'll go from there.
