Thank you for all the replies. Yes, I change my oil every Sept before winter time. Glad to see others with their original chain. I hope you are the first owner because I am.

Most of it are highway miles. Maybe the chain life might change if you are doing a lot of offroading. I want to keep it that way to see how long it would take before I get a stretched chain code.

By the way, I use amsoil synthetic and filter eversince.

I wonder how often you change your oil.

Good info there. Me at 10k or 1 year with amsoil.

Now at 143000 miles. Full syn oil every 6000 miles. Never changed out the chain, and never will.
Most likely sell within few years anyway.

373k miles. Original timing chain.
Mobil 1 synthetic extended performance high mileage 5w-30.
Oil changes every 15k miles.

I thought that the 4.7 V8's had the infamous timing belt problems. I don't think you need to change a timing chain unless it needs it (hence why they switched back to a chain) because they are more durable. Or I could just be an idiot (very real possibility). Also, change the oil every ~5k ish.

what problem would that be?

203k miles

Never touched the chain and hope I never have to... still going strong and I hope it stays that way for miles and miles.

GupsT4R · 02-11-2020, 10:16 PM

sadly at 190km

rwh963 · 02-12-2020, 08:38 AM

210k on mine (meaning still on the original).

I think they would wear out after about ~100k. My Father had a GX with the 4.7 and his wore out right at 100000, as did my Mom's at a slightly higher mileage. I think (?) that the 4Runners equipped with the V8 had the exact same engine as the GX 470's.

ah. that's not really a problem/flaw inherent to the v8 engine. its EVERY timing belt engine. the belt is a maintenance item. our are good for 90k, others are only 60k. not a problem, just a different design.

I put the original back in at 170k when I did the head gaskets. It was in new condition.
