I have removed the engine from a 2008 3speed. It has around 190k miles. I got it from a friend who was the 2nd owner. It had what appeared to be a bad head gasket. It has great service records with many oil changes and other services. It does have a K&N intake and filter and a Cobb access port with what I think was the stage 1 tune installed (I wonder if this caused the head gasket problem???). I did a leak down test and cylinders #1 & #2 were fine, but #3 leaked a lot of air out the spark plug hole in #4. So I took the engine out and it did have a bad head gasket. The head is at a machine shop getting refreshed. So while I have the engine out I plan to update/replace the following:
  • Timing chains, the VVT and tensioner
  • Clutch plate, throw out bearing and pilot bushing
  • I removed the engine balance shaft and installed the Corksport oil pan baffle.
  • ARP head studs
  • New PVC valve
  • New power steering hoses, they were badly rusted and has started to leak
  • Corksport rear motor mount
  • Timing cover crank seal
  • Cam cover gasket
  • rear main seal
Should I replace or add the following items while I have the engine out:
  • Water pump, thermostat?
  • O2 sensors
  • Pressure plate (do they go bad? my other MS3 with 216K on the original clutch is doing great)
  • Fuel pump high pressure internals
  • Oil cooler, Oil temp and pressure gauges? (I plan to do a few track days with the car down the road)
  • Anything else??
Thanks

Oh can anybody tell me the part number for this part? took it off the engine weeks ago and forgot where it came from. Upon inspection recently I noticed a small rust hole forming. I can't find it in the a Madza parts catalog. I tried looking under coolant parts but did not see anything that looked like it.
