I did the timing belt kit myself on my Odyssey. This outcome was my worst fear so I followed the factory service manual instructions to the letter and triple checked alignment before daring to start it.

[@billbarney4937]

you need a service manual or cd for your specific model and manufacturer and year (ie say 2003 honda accord). helps a lot so youre sure the belt is properly aligned

[@iboswell]

It also really useful to mark all the pulleys and old belt carefully and compare against the new belt going on i.e. pre-mark the new belt in the exact same place. Occasionally you will find that some belts do vary between model years i.e. one might be slightly longer and this is a good way of double checking. A Peugeot 306 tried that one on me so just as well I checked...

Same here, did my very first timing belt / water pump on my wife's 2006 Toyota Highlander Hybrid last summer. It was both exciting and terrifying but in the end was not the huge deal I made it out to be in my own mind. I also have a Honda Odyssey and plan to do the timing belt on that one too.

[@cwmoser]

I never thought about the correlation between voltage drop/current increase by the Starter when the Piston travels up under compression as a way to find a low compression cylinder. That was indeed interesting. Thanks for the great explanation. I have several Oscilloscopes I use for nonautomotive work, I might see if I can set one up the way you described it. Again thanks for showing us this technique to find which which cylinder has low compression. Also, us amateur DIYer's got to discern what we can do and what we can't do. If I can find a shop with someone like you with your diagnostic skills, life would be gooder.

[@jasonalexander6417]

I mark the crank, the cams, and the belt before taking the old belt off. Then I transfer the marks to the new belt and then put it on. I was made fun of for doing that and called an idiot, but it worked out great for me. Seeing this validates my methods. I also turned the crank manually several times before starting it just to make sure nothing was hitting the valves.

I've been bitten by the getting in over my head stuff, too had a BMW 330xi that would randomly run rough. Went to some forums, watched a bunch of KZbin videos, and became convinced that it was a VANOS issue. (A variable valve timing system that would allow the engine to dynamically change the timing of the intake or exhaust valves based on RPM). After dicking with the fuel injectors, coils, etc., I decided to jump in and disassemble the entire top end and replace the entire VANOS system. Didn't help much. One of my neighbors, who used to work at AutoZone lol, tell me that I should check the oxygen sensors. Nah. I would have gotten a code for that. I had a BMW scan tool, and a laptop with a factory program that would allow me to check and change all manner of things. I had just decided that I had driven her too hard for too long, and I'd have to live with an intermittently rough running engine. Well, I gave the car to my niece when she went to college, and the next summer, she said that it was getting worse. So I decided: "What the hell... O2 sensors are cheap, might as well change 'em. Wouldn't you know, that car ran smoother than it had in many years, and she drove it about 30,000 more miles before she sold it.😂

[@scottelder3141]

Having done a honda v6 timing belt as a diy'er, there is a trick to make sure the belt it in the correct position before pulling the tensioner pin. Before you pull off the old belt, use a paint marker to put wittness marke on the cam zero marks and a mark that you mark on the crank. I always mark the points on the belt the same way, either point or tooth. Pull your old belt and transfer these marks to your new belt. Install the new belt, lining up the marks with your cam and crank marks. Once the belt is installed, hand crank the engine 2 revs and the thr marks should line back up.

[@SteelheadTed]

An OEM belt already has marks on it that line up with marks on cams.

[@scottelder3141]

@SteelheadTed I bought the Aisen kit from rock auto. It comes with a Mitsubishi belt which I believe is OEM, but no marks.

[@craigw3033]

I did this on my two honda timing belt replacements. It makes it so easy. It's easy to not pull the belt tight enough and be one tooth off. The marks you make (different from the cam and crank TDC marks) make it easy to see if you're off a tooth.

So I pull the covers and TDC the engine, the firewall side cam was a 9 oclock, right where it lands if the cam springs without the belt on, so I reset the cam and finish that part.

Very good!, also remember on Honda Acura J35 motors , valve lash adjustments are needed every 30 k , they are sensitve and many times they are tight to zero lash because no one has done the service.

[@steve2736]

Absolutely correct. I just did my valve lash adjustments on my ‘04 Pilot (200K miles), along with sparks plugs, spark plug tube seals, pcv valve, valve cover seals, and spark plug boot seals. Obviously the exhaust valves were tighter than the intakes. A GOOD manual is imperative.

[@johnmac9055]

I see this as well. Customer complains of misfires and previous shop throws plugs and coils at it but the misfires continue. I perform a valve adjustment (the valves are almost always too tight) and the vehicle is running fine again. I don’t know why this isn’t more well known.

[@watchwizard321]

Every 30k??? Honda disagrees. Honda recommends inspecting valve clearance every 105k miles. The exhaust get tighter, the intakes get a little looser, but most people at 105k are still fine. I'd say 150k is really the point where it should be brought back to factory specs, and the valve cover gaskets will likely be hardened and starting to leak a little by then.

did you time the engine before you did the relative compression check? and was it out of time that bent the valve?

[@theroyaltyautoservice]

The sync was connected to the signal wire to the ignition coil. You can find the connector pin out in service information. The amp clamp was on 600 amps. The Escope does not need attenuators. One of the best things about it. You don't have to worry about damaging it when you connect to a vehicle. As long as the waveform is displaying how you like to see it it doesn't matter.

I had a no start in my bay that cranked and I thought for sure it had a compression issue by ear. Put a scope on it and the rc test showed uneven peaks relative to each other. In the end it ended up being a fuel pump issue and a starter. The starter was causing the erratic rc waveform and the failed fuel pump was causing the no start. Rc test only shows you starter motor amperage or drops as the motor is loaded on. That's all. It shouldn't be the only test. It doesn't mean you should sell the customer a head job or engine because it failed an rc test and you assumed it crashed a valve. That's why it's important to finish diagnosis even after an rc test or any current ramping test being performed. You may have a washed out cylinder, valve stuck open by carbon , valve adjusted too tight, customer may have dropped something down the intake, ect.

I would not stop at the RC test,i would go a little further to see if i could pinpoint what is the issue. Depending on the engine and acsessibility follow up with pulse sensor on intake/exhaust, or leakdown test or borescope affected cylinder or we might even go incylinder on some cases. Thank you.

[@flacarpetracer]

that is fine, but its just more work. nothing will be gained. you already know what cylinder head to pull off to fix it, and as soon as the head is off, you will see the problem. one of three things - bent intake valve, bent exhaust valve or a friging hole in the piston, or a hole and a mangled valve, yea thats four

[@mrblonde2013]

​@@flacarpetracer i have been fooled by just doing an RC test, i back it up with another test. Lets face it, i already have the scope out, just hook up 2x more leads to say intake pulse and exhaust pulse, it only takes a few minutes to get more conclusive data.

[@theroyaltyautoservice]

I don't disagree. It depends on the situation. This is a pretty unique case. But ended up being a great opportunity to show how to do the RC test. When he picked up the vehicle he told me he let the cam slip when he had the belt off. He took it and said he can do the work himself.

[@curtisj2165]

I will wrench on my car, but i would not touch a timing belt. As Dirty Harry said, "every man must know his limitations"

[@gulfrasta5844]

In fact i haven't purchased a Honda V6 after 2001. I bought a brand new 01 EXL V6Taffeta White. I traded it at less than 75k miles 5 years brcause the paint faded. It was a bad year for white.

[@michaelpowers4731]

Always put your amp clamp arrow away from positive terminal or toward negative terminal and you won’t have to invert it

[@ghostwrench2292]

Sorry but checking comprsssion is not my first step when a car comes in with a misfire. I check plugs first. It’s easy to see a plug that is worn enough to cause a misfire and I would say 90% of the time, it is in fact worn plugs that are the cause. If the plug looks ok, I’ll go ahead and stick a borescope in the hole to have a look around. However, I do really like this method of checking relative compression. Thanks for rhe tip!

[@mrblonde2013]

What if the plugs are not accessible?

[@red7fifty]

To the owner of the car, the cost of the repair, is part of the price of mechanic education.

[@ddblairco]

thank you

[@markanderson350]

I have now done 2 timing belts myself and never watched KZbin. Its just common sense. I put it on snd hand crank a few turns to make sure i am not off a tooth. I did a v6 and i was so i re did it. I had a hydraulic tensioner on that one. I really dont want to be a mechanic. The first was to save money, the second was for my friends son.

[@TheDutchGambit]

This is a great video, now what, borescope all cylinders to check for damage (if non) take cylinder head of with bent valve and repair it (valve and valve guide). Engine only has 100K on it.

[@theroyaltyautoservice]

He took the vehicle and is going to remove the heads and have a valve job done.

[@red7fifty]

Great Video. Here is the easy fix, put the old timing belt back on. (That's a joke guys, just making sure you're paying attention)

[@bryantwhitis6446]

This should have been a shop job. On a job like this no room for error. Even myself as a diy I draw my line in the sand. And this would be one of them

[@davidmann4533]

Changed many a timing belt and head gasket no problem

[@steve2736]

@@davidmann4533 Precisely correct. One must fully understand the sequential steps, their correct order and adhere stringently to published torque tables. On the J35A4 engine, it’s the hydraulic tensioner that does all of the work, and most frequently the part which fails causing belt wear and tooth jumping.

[@charlesmecum5009]

What if u dont have scope? Can u still go to ATS training

[@theroyaltyautoservice]

Absolutely, just let them know you need to use one of their scopes while you are in class.

[@strikeryachts]

Cool show !

[@blumobean]

Never fire up an engine after timing belt replacement until you have turned the engine over by hand a couple of times. Never!

[@theroyaltyautoservice]

He actually bent it when he had the belt off. He let the cam slip. When he picked up the vehicle I talked to him and he knew right when it happened.

[@mrweisu]

I didn’t expect that it’s harder to read with a fancy amp clamp

[@RD-qp3mu]

Toyota techstream allows you to do a relative compression test without any battery clamps. It must use the current draw sensor fitted on the battery clamp, or voltage sensor.

[@theroyaltyautoservice]

It uses the voltage drop at the DLC. The EScan will do it also but I wanted to show it on a scope. Ford software will do it too.

[@RaymondKunkle-pk2sd]

Can't blame the guy for trying .these shops charge one to two hundred bucks in labor .

[@iwhineTL]

A lot of Honda & Acura owners are simply too cheap to do a proper 105K service, which also including replacing the spark plugs and valve adjustment. They hear prices well over 2K and immediately say "F this" and prolong the service or try to source out the parts themselves to either attempt the service themselves or have a Indy shop do the repairs. Here's where they continue to make mistakes by buying the "OEM" timing belt kit from amazon or Ebay not realizing these are NOT OEM but counterfeit kits in Honda or Acura bags. They end up using these parts just to have a failure around 12,000 miles. Now just imagine such vehicles like the MDX-S or TLX-S where they have high performance low profile tires, brembo brakes, timing belt, air suspension ect... Your typical Honda / Acura owner will not be able to keep up with those hefty repairs when the time comes around for replacement. Most 105K services are almost usually skipped and the next person to purchase these vehicles are lied to being told "Timing belt was replaced"... surprise surprise later on down the road.

[@jankarlsson118]

I really appreciate your videos but why not just measure the compression with a ordinary compression meter?! The video would be much better if you did that. Happy Holidays from Sweden!

[@theroyaltyautoservice]

This technique is much faster. Especially if the cylinder is under an intake. Happy New Year!

[@sheerwillsurvival2064]

Great video

[@kissitnow898]

Watched several videos on the timing belt change for my 03 Highlander. Could I do it... maybe.. Should I do it.. No way

[@kevinbarry71]

I guess this guy didn't do the last ditch check, gently bar the engine over to make sure everything clears before you start it

[@flashover8231]

" How's it go? " 😆

[@dmulkearns]

So did you fix the engine??

[@theroyaltyautoservice]

No, he took it and said he is going to do the work himself.

[@dmulkearns]

@ I guess he didn’t learn a lesson

[@ryans413]

The owner didn’t time the engine properly when putting on the new belt and bent a valve.

[@steve2736]

Sounds like it.😱

[@theroyaltyautoservice]

He actually had it timed correctly. But he told me, when he came to pick it up, that he let the cam slip when the belt was off. That's when it bent the valve. Really bad luck.

[@charlespaluha1247]

I'm not sure if I've asked you. But where did you get that flashlight holder that's on your right hip. I asked my snap-on dealer and sent him a picture he has no clue.

None no one ! lol. Again very interesting one (or no one :)

[@BlewShirtGuy]

I always appreciate the content, and getting to learn, but let's not worry about the algorithm with the open mouth thumbnails please. Also, how can you do a relative compression test when the timing is off? If valve timing is off then you are going to get inaccurate results as valves will be open making it seem like they might be bent when they are in fact not, The engine just isn't building compression.

[@theroyaltyautoservice]

Timing was set correctly on this one. He let the cam slip when he had the belt off. That's when the valve bent. Thanks for watching!

[@Chuck_in_CT]

I've done many Honda timing belts .. I always have someone else verify the marks before pulling the pin

[@steve2736]

Yes that’s smart. But even if you pull the pin with the cam off mark and see it, simply remove the belt, remove the tensioner, and recompress the tensioner piston GENTLY, in a vise and reinsert the pin.

[@JohnJones-ew6io]

Haven't seen this recently with customers. They tend to panic and let us do the job. The rear cylinder is a bitch to get the belt on because of the lip on the end. The passports and the pilots are the worst cause the motors sunken down in the chassis. We have the special crankshaft socket to get the superman tight crank bolt off. Works like a dream.
