Just finished 30K SC maintenance

Well it wasn't difficult, just time consuming. Thought it would be helpful to share a few observations and thoughts.
1. Front plugs were excellent and had the same gap as install. Back plugs looked good but gap had increased about .020.
2. PCV valve was clogged. Damn thing is plastic. I just replaced it since it sits under the SC.
3. Changed belt and used Dayco #5060885 (6PK2250).
4. Old SC oil was the color of light Maple syrup. New oil is slightly white.
5. Inner section of throttle body was dirty. I suggest cleaning it.
6. My coupler was in excellent condition. Snug on both sets of prongs with no apparent wear.
7. All the TRD vacuum hoses from the SC kit were cracking around any fitting it was attached to. I had to replace them all to be safe. Original Toyota hoses were just fine.
Changing SC oil is time consuming. Once you crack it open, you need to clean all the old oil out and clean the mating surfaces well. The Loctite 510 Magnson gives you takes a while to cure (2-12 hours depending on the temperature). DO NOT use a lot. It only cures anaerobically meaning it sets up in the mating surfaces only where it's not exposed to air. It will not cure if it oozes out the sides and contacts air. Needless to say you do not want any oozing inside the nose unit. I applied a small bead to the outter edge mating surface of the nose unit and spread it thin with my finger making sure I applied some around the bolt holes. I bolted it on and let it cure 5 hours.
Well, I was very happy that the car runs great and I didn't forget to do some simple thing. As a side note, I carefully drilled and tapped the flat circular area towards the back of the current boost port and it works great! Took off the washers and no rubbing. I DO NOT recommend this unless you are very careful not to leave shavings in your SC. A used SC has an oily residue inside and can trap the stuff like a magnet.
