My findings with AISIN timing belt and replacement saga

Funny thing is that I took the dog to the groomers this morning and a V6 Accord pulled up next to me. As I get out of my Tahoe with the dog I can hear that car making the warble noise. 🤷🏻‍♂️

Maybe he used the Aisin kit also!😲 I am confident, that someone, somewhere knows what this noise is, and how to fix it.
 
When you release cams from their timing belt/ chain bondage they close. They want to close, the valve springs are making them. If they don't close all the way they'll close to an average of all the valve spring pressures, which should be enough to avoid damage if a piston comes within kissing distance.

I have yet to need to use a fixture or contraption to lock my cam gear. Generally just count teeth forwards from where the marks line up when it's resting naturally where the valve springs want, then repeat on the crank, put the bolt back in with plugs out, crank slowly by hand, to see if the marks line up on the next go 'round.
 
I've done three J35s with Aisin kits, haven't noticed the troublesome noise. Then again, I like to listen to Jimmy Dale Gilmore, so maybe I just like warbling.

It doesn't work this way.
 
I’ll try to keep this short and sweet but just wanted to talk about the AISIN timing belt kit for my J35 Accord. 2 1/2 years ago and under 30,000 miles ago I had and Indy shop replace my timing belt, water pump and blah blah with the AISIN kit. I didn’t feel like messing with it at the time and the AISIN kit was way cheaper then Honda parts but high recommend. Car alway made a strange warble noise with this kit but didn’t think much of it because it was faint. Lately it got to the point that I could hear it with the hood closed and I didn’t like that so I bought a Honda belt, water pump, and tensioner.
Yesterday we were slow at the body shop so I started the job in the afternoon as I tore the engine down first thing I noticed was the tensioner was wet. Great that’s already leaking and failing. Now this is where it gets good and I made a bone head move. I didn’t rotate the engine to TDC before taking the car apart. I had the crank shaft pulley off along with the alignment key and it didn’t dawn on me that the timing belt sprocket would spin freely on the crank shaft. I then set the timing of the engine up top by lining up the cams to TDC. Then when I went back down to the crank shaft area I seen that the sprocket moved but the crank didn’t. My stomach immediately turned to knots because I assumed that I caused bent valves. Now I went ahead and lined up the crank in the timing marks and made a couple phone calls to a mechanic friend to discuss what I had done and he said that I should be okay. Nonetheless still worried, I continue on with the job because IF the damage was done it’s already done and I won’t know until I start the car. I finish the job and rotate the engine assembly a few times to make sure that everything was in time and all looked good.
Time the cross my fingers and start the car. The car starts right up with no issues what so ever and is running like a sewing machine. I let it warm up and check coolant and also no more weird warble noise. So in the end everything worked out and saved myself a ton of money by doing the valve adjustment, timing belt and water pump myself.

TLDR :)
AISIN timing belt kit made a warble noise and tensioner was leaking at low mileage. I didn’t correctly set time on engine while taking car apart and about had a heart attack thinking I destroyed my engine. End result is that everything is okay and no more noise with Honda parts.
And if you did mess it up then no savings at all, it could have cost either an engine or overhaul. DIY on some things is good, but learning major engine or transmission tech on a needed vehicle is not the place to learn.
 
Agree! I had the warble in my Honda Pilot. Honda had a bulletin to use some sort of wedge to stop the warble noise. I had it replaced twice. Yes that is correct t 2 times!. Finally I had it done at the dealership,...no noise.
The need for a shim implies that the warble is caused by an alignment issue.

I wonder if the genuine Honda WP is built at the correct angle, and the aftermarket ones aren't.

"Yes that post was me. And I am sad to say I have that warble noise back again. It certainly is a crap shoot! I am so mad!:mad: I seriously do not know why some parts have it and some do not. I wish mine did not, especially after having had this job done 3 times. 2 times with the Aisin kit at a local mechanic and once with the OEM from the dealership."

I am cornfused- here you say the "warbling" noise is still there, "back again" even with Honda OEM. So...is the noise there or not? I've been following your adventure with this noise thru many posts and sitting on the edge of my seat for the next chapter LOL:ROFLMAO:
