I believe the later revision was to thread the starter. The top nut for the starter is my least favorite fastener in the entire car.
Today, I removed my upper intake manifold in order to replace the coolant hose from the lower manifold to the ISCV, which I damaged while removing the ISCV in order to replace the injectors.
I did indeed have a silicone hose for that, but the stock constant tension clamps won't fit over it, so I need to get other clamps for it. I don't think that it needs much pressure to prevent it from coming off/leaking, so I'll just pick up some cheapish worm clamps, and leave the heads facing where I can get to them easier next time. (The constant tension clamp had the tines facing straight up under the manifold. It's a good thing that I decided to remove the upper manifold to get to them, because otherwise, I'd have had to lift the motor.
In the silicone hose kit, I can't find the hose that goes to the throttle body, nor the one between the TB and the ISC. (I figured that I'd just change them all over.) I did find vacuum hoses for the brake booster, which I wasn't really expecting. I know that there are some PCV hoses, and the ISC ones as well.
The cold start injector is totally gunked over with oil and grease. I figured that I could clean it with carb cleaner. The inside of the intake manifold is all pretty gross. There's oil getting in the intake from somewhere. Probably the PCV system. The lower IC line didn't look too bad, so probably not intake side turbo seals. It'll be a good thing when I swap out this motor. In the meantime, I think I'll use the upper intake manifold that I prepared with the TB and ISCV and EGR that it already had.
Looking at the intake manifold, and I see that Toyota took a lot of care to make sure that everything coming into the intake came in at center. The ISCV, EGR and TB are all centered on the runners. This is obviously not possible for FFIMs, or are the people making FFIMs for the 7M taking this into account and doing something to make the FFIM work in a similar manner? If there's EGR/ISC, are they running that to the base of the TB? What about cold start injectors? Those (when present) seem to be still in the center of the manifold.
