Hi Lewis. Yes We have all new vacuum lines gaskets seals O-rings breather hoses. We've already checked & cleaned the SAI's while we were waiting for parts. We also ordered some silicone boost hoses too. After it's all said and done I plan to put another 130K miles on this beast!

The SAI themselves? or the metal check valve on the back of the engine?. Part number 10. They get clogged and stick open causing rapid sai failure as the exhaust heat and soot wrecks the sai pump. Ask me how I know. 

 

One more thing is the thermostat, it's 25 bucks and really not worth the hassle if you have to change it later.

Oh I nearly forgot,..... take out your cam solenoid actuators part 21 and clean oil strainer 20. Its one bolt 22 and 10 mins work. In the future they will never be blocked with oil sludge debris etc and stop the variocam working! Pls take pictures of this and other stuff like the broken cam chain guide, stretched chain etc. It's great for the forum and a nice way to give something back. Thumbs up

 

Omg if only I had known what I do know when I had my engine out on the floor.

we cleaned the pumps since we had to take them off anyway. The valves will be changed along with all the other hard to get at stuff while the engine is out. thanks for the tip on the solenoids. I'll upload more pics as we go forward.
