Lower intake manifold gasket replacement

[senordan]

Hey you all! long time lurker here. I am about to replace my lower intake manifold gaskets due to the constant amount of coolant pooling around manifold and the valve covers. I am afraid of what I am going to find, specifically rusted bolts.
Anyone know the part numbers of the bolts holding the lower manifold?
For someone that recently done this job, anything insight on the job would be greatly appreciated!

I just did my knock sensors and my bolts came up great after a bath of degreaser. That being said, here's the diagram for the intake. From what I can remember, it looks like you'll need 4x 90148-80002, 4x 90119-08609, 4x 94623-10800, and 4x 90179-08117. Might be better off just taking the bolts that come out down to the local hardware shop.

As for some insight: this thread is a great reference for torque specs. Also, it might be overkill, but I used paint pens to mark holes and bolts, which I then put into a zip lock bag. It made re-assembly dead simple.

Thanks! this is very helpful. I happen to stumble upon Toyota Maintenance's intake manifold video: Toyota Intake Manifold removal nightmare ! - YouTube

He did mention this being something of a nightmare!:lalala:

I've done it 3-4 times for sure now. yea it sucks.

this site has good parts diagrams and also some things even have real pics of the actual part IRL.

last couple of times I have done this job I took the truck to the car wash and pressure washed the engine. I also use the soap feature to help cut the oil buildup around the area's I would be taking apart.

things like to fall into the engine and getting it cleaned off will help quite a bit. when the engine is a oil coated slip n slide with sand and bust and stuff is falling into the intakes.... yea not good. so take some time and get it nice and cleaned up before you dig into it.
