I just finished the first valve adjustment on my '02 Acura RSX. The owners manual says the first adjustment is 110,000mi,and subsequent adjustments are 110,000mi intervals. I used 20-weight oil exclusively since new, except for one interval of Mobil1 0w-30 early on. I did oil analysis regularly which led me to choose Havoline 5w-20. Most of the oil changes were with Havoline or Chevron Supreme 5w-20. I thought you guys might want to see the pics.
Here's the oil cover. I'm pleased with the cleanliness. There's no sludge or varnish that I can see:
Here's some valvegear photos:
I tightened all the intake valves clearances a little. All the exhaust valves were OK except two where I opened clearance just a little.
Here's a picture of my OEM iridium spark plugs after 109,000mi:
I'm really pleased with the reliability, durability, and low maintenance of the engine.
