You are correct. I started at the back of the 2004 Corolla maintenance book, and took the first one.I believe the interval for checking valve clearance is actually 60,000 miles. May be up to 7 missed adjustments.
Apparently not true as these checks have never been done...I guess my car is a miracle...
Mmmmmm glorious 5 cylinder noises![]()
The real problem with the J35 isn't the timing belt, it's the VCM!
wasn't it the tensioners that would always fail?This isn’t exactly true. Excluding the ea888 gen 3 all the 4 cyl or less now use belts. All engines over 4 cyl use chains with no issues on any of the current production units.
I'm not certain if chains are superior, but Honda belts are super easy to replace in the J series - maybe 3-4 hours even for a DIY like me. I've changed 4 of them now. 3 were right around the 100k mark and the belts looked just fine. 1 was in a co-worker's Honda Pilot with 190k miles on the original and it was well past its prime. Personally, I love the design of the J30/32/35 and think it is one of the best V6 engines ever made.I don't get it. Chains are far superior, yet Honda keeps using belts...makes no sense...
Yes, the original design of tensioner is the week link in the ea888 gen 2. It’s designed to ratchet out and take up the slack but the teeth brake off and allow the chain to slacken off on start up. Timing jumps, game over. The issue of chain wear/ stretch is a secondary issue that in my experience if the latest tensioner is fitted and the oil is changed on time with 504/507 isn’t an issue. Neglect an engine anything can go wrong!wasn't it the tensioners that would always fail?
I shouldn't say the valve clearance has never been checked on my Corolla because it had 148K on it when I bought it. The original owner may have had it done, but it hasn't been since I've owned it...
Yet here’s one that jumped at 60k:All this talk about guides and buffers wearing out. How is it my Corolla is still on the original timing chain, and all of its associated parts, with 423K miles and never needing any repairs?
this is why the UZ V8 and lots of other direct bucket engines have no interval at all.If the exhaust valves aren't already riding the base circle of the cam Id wager they are really close to it.
Yes, not pretty.Remember when the Ford 351s would clog up their oil screens with disintegrated nylon timing gear debris?
Not missing, not needed...Sounds like your daughters habit of missing service items is passed down from you!
That's correct...Okay but you have added 300,000 on the motor and not checked the valves?
