FYI, All 4th Gens came with ATRAC.

Theirs no bar in the visor to bend like the old style visors. Just buy a OEM visor. Trust me, it’s worth it in the long run.

This is from NGK web site.

You don’t have to use anti seize on the plugs. The MFR doesn’t recommend them because the threads/metal are coated with anti seize. If you do, they will seize up when you remove them. Toyota doesn’t recommend the iridium plugs for the V6 and change them out every 30k miles.

You're right, coils USUALLY work or dont work. But overtime they loose their efficiency. Coils produce thousands of volts and a lot of heat. With 250k miles on the original coils and the heat from engine will degrade the coils. Ive owned my 4Runner almost 16 year's now and I change my plugs...

Change the ignition coils for better gas mileage/throttle response. I would recommend you change all the ignition coils. I have just over 255k miles and I replaced the coils when I changed the plugs. I've noticed a gain of 2 mpg and a better throttle response. Bought 6 Denso coils on Rock Auto...

Like everyone said, don't worry about the WP until it makes some noise or leaks. I'm on the original WP on my 03 with 255k miles.

Oil change every 5k miles with conventional oil.

I had the same issue and ended up replacing the drivers side CAT PO430. I was told their was only one California Approved CAT available at the time for the 4Runner. New CAT and labor was $1000. You should check the gaskets after the CAT to see if they are bad just to confirm its not the gasket.

Im still on the original timing chain at 254k miles.

On my December Trip to Alabama Hills, it got down to 28 deg at night and it snowed. I slept in my tent with a 30 deg sleeping bag and 32 Deg Heat long Johns. To help keep me warm, I added two Super Warmers by Hot Hand in my sleeping bag and I was nice and warm. The 2nd night I used 3 and it was...

Just passed 253k miles on my 2003, V6.

Its a common issue with the 4th Gen and 5th Gen. Possible issue could be its coming from the rubber hangers for the exhaust/muffler. I have over 253k miles on my 03 and I still get the burning rubber smell now and then.

Thanks for the info! I already replaced one CAT 3 years ago (PO430) and now im wondering if it was the just the gasket? I also got a PO420 a couple times in the past 3 months so I will have to check/replace the gasket before I buy another California CAT.

If the plugs were soaked in oil, then the spark plug tube gaskets are leaking and should be replaced. Common issue. You should start with replacing all 6 tube gaskets before doing the HG and go from their.
