It’s been three years and 25k miles since the last cleaning so I thought I would do it again to assess a good interval…and I’m already doing a bunch of other maintenance and cleaning chores.
The MAF was perfectly clean visually and the TB was clean on the frontside with a little staining on the backside.
I will probably increase the interval to 4-5 years and about 35-40k miles.
I replaced the air filter at this time as well.
I did see what looks like some minor rodent damage on some wire sleeve material for the fuel system. I didn’t look like chafing damage.
I put some electrical tape over the damage and will keep an eye on it.
While I had the cover and intake off I vacuumed up a bunch of sand between the cylinders too. The intake was fully protected while I did this.
