I had a problem with loading WIS from the eBay disks so working on that with the tech support. I will share with you once I get it going.
It it has taken a lot of time so far but nothing really complicated. The 4 or so videos on YouTube and couple of posts here are awesome.
Tools that I bought were crank pulley holder, T60, 27mm deep impact and 2” extension, 1/4” e10 because a 3/8” doesn’t work and the Matco swivel e12.
Replace the crankshaft sensor. I hear it is a pain to do with engine in and it is in a heat soak area so prone to fail.

You'll need the rear main seal tool and the pin pullers for the chain guides. The pin puller is easily fabricated if you don't want to buy it. I agree with Viper - it's just time. The work is not overly complex.

I am also replacing the manifold actuator with a metal one instead of plastic. I have read enough about them breaking and the freakin intake needs to come off. Might as well fix it when this is being done.

Cmriv, Balance shaft is left thread too...right? So need torque wrenches capable of counterclockwise.
Where did Did the heat gun come in handy? Upper oil pan I assume? Timing cover?

yup heat gun to remove oil pans and front cover. I would suggest making a cardboard template for front cover bolts. multiple different sizes and lengths.
recommend using a rivet to hold cam adjusters in place prior to removal and during re-install. Or a skinny punch would work.
wire brushes and razor blades do wonders during cleaning, you are going to spend probably an entire day doing that. I would get some loctite gasket remover if i were you, makes a day and night difference in cleaning.
MAKE SURE YOU DON'T TOUCH THE CRANK PULLEY DURING REPAIRS.
AFTER YOU RE-INSTALL FRONT COVER AND INSTALL TENSIONER, ROTATE THAT BAD BOY OVER HOWEVER MANY TIMES YOU WANT WITH EVERYTHING OFF MOTOR TO MAKE SURE 1000% THAT ALL TIMING MARKS LINE UP!!!!!!!! Don't wanna have to do it all over again if you catch my drift.

Thanks again. I wasn’t going to use a heat gun but I am removing the upper oil pan this weekend and that is a great idea. The lower one was a pain enough.
One last thing that I haven’t been able to wrap my head around. I read that you have to remove the cam bolts and impulse wheels to get to the head bolts to timing cover. Can you really get to the bolts then or do you need to also pin and remove a gear? Not that it is a big deal at that point but just asking.

the black portion of the lower oil pan has a threaded hole to help with removing it. apply heat and gradually insert e10 in hole and it will pry off.
Yes, you need to remove pulse wheels and adjusters to access those bolts. You also wouldn't have enough slack in chain if you didn't. It's possible to do it with them installed but by this being your first time i would advise you to r/i adjusters!
