Heads up Honda J35 V6 owners

[harrycalahan]

2013 Accord w/ 145k miles on it. Last timing job in 2020 at 100k with all Aisin parts. Went to leave for work yesterday morning and had a severe misfire on start up with P0300/301/302/303 dtc’s. All bank 1. Even threw a “FCW failure” across the dash (unrelated). Just had a chance to look at the belt and it jumped 3 teeth on bank 1. Belt looks perfect. Im guessing its stretched excessively since I had no prior symptoms of a failing tensioner. I’ll find out more next week when I get the lower cover off and replace everything. Could be a bleeding tensioner. Read on several other Honda forums of this happening with Aisin stuff as well as direct Honda parts. So Im just going to make up my own kit I guess. A mix of Bando, Continental and Gates maybe. I dunno. Very disappointing. The only symptom I had was a slight skip on startup when cold. But its done that for the longest. Now Im thinking the cam was progressively becoming -out of time- from a stretched belt and the tensioner maxed out when it jumped. Bank 1 cam is just along for the ride and depends solely on the tensioner to maintain correcting positioning. Think I’ll steer clear of all Aisin parts this time around and see what happens.

Keep us Informed.

I'll be interested to see what kit you build. My wife's van will need a new timing belt pretty soon.

Well…I ended up ordering Aisin again but also ordered an additional Bando belt. Bando belts have always been excellent for me. And I wanted a secondary brand to compare lengths with. After reading reviews, the Continental kit is all Aisin hardware with exception of the belt being continental. That kit would have been fine but it was more $$ and longer wait time. The Gates kit gets good reviews but outside of rubber products, Gates quality suffers. Mostly chinese hardware. I had two of their waterpumps fail in the first year on two different vehicles. And Im not chancing that on a Honda. The rest of the kits I have no clue about and are no-name chinesium. So my plan is to inspect the tensioner for failure and then compare belt lengths between the two new ones and then the original to see if it stretched.

I have a 2012 odyssey van that had almost the same think happen to. The front 3 cylinders had minimal compression so I pulled the head. The valves on 1&3 had touched the pistons just enough to park the carbon but not the piston. Took the head to the machine shop whe trued a warp out but didn't find anything wrong with the valves. It's still sitting here apart cause I'm not sure i want to put it back together with a 3rd new timing set and gaskets. I could probably get a remain for not much more and be sure not to have that problem again.
Oh and the milage was around 145k

Double roller timing chain or straight gears for the win.....You probably can't change that one

Did yours jump time?

Did yours jump time?

Yes sir. The tensioner collapsed and it was tapping really loud. It hadn't jumped time at that point so I put a new asin kit in. 3 months later it startd mis firing on the front 3 cylinders. That's when I found the low compression. They (my parents) took it to the local Honda dealership who said it jumped time and put a new set on it again. It jumped again on the way home so they brought it to me with the title.

What the crap…

I've been battling with some physical issues for 3 years and it became low priority. I'm going to fill the vavle face with mystery oil and verify the machine shop checked and faced the valves
