Default replacing 04 Sedona timing belt problems

I have recently taken on the project of replacing my timing belt. I had all the timing marks lined up when I took the belt off. The right bank cams did jump, but I got them back on their marks. I got the new belt on with new pulleys and auto tensioner. I went to start it, after rotating it by hand first, and now have a miss and a slight tapping like a lifter. I stopped the engine and rechecked my timing marks they were still the same. Anybody have ANY suggestions are some other advice, PLEASE HELP! I have been working on this for over a week after I get off of work. I just want it done.

Did you also check the timing marks on the crank pulley? Just a thought.
Did you see the recent post by "humphry" on his replacement of his TB?
He did a super job of documenting it with text and pictures.

Yes, I did check the crank pulley mark, it was off maybe a half a tooth. Tried repostioning it back and forth. Bringing it forward made it worse. Yes I did see the post from Humphrey, I did exactly what he did. Didn't work for me.

a possibility could be, if your engine has hydraulic lifters, one of them has leaked down and isnt opening the valve properly. my daewoo rattles like skeletons in a dustbin if left unstarted for more than a week and if left longer can take ages to quiten down
if you suspect there has been a valve/piston clash when the cam jumped, try a compression test

Hi ditchboy,

I do feel for you. I know what its like working on the car after work - only able to get a few hours in on it each day.

I am not sure what you mean when you say the car has a miss. Are you describing that it is not firing on one cylinder?

One thing I can tell you is if the timing marks on the crankshaft appear to you to be off by half a tooth, this would then also mean that if you line it up exactly, then your cam marks would have to be off slightly. Since everything runs off the crank, you may need to realign the crankshaft marks, remove your belt again, and then realign the cam marks.

The cam marks should not be too far off if your crank is only off half a tooth. That's going to feel like a big pain in the butt to you since you've already been at this for awhile but for your peace of mind it may be worth it.

Also, verify your cam mark alignment by sticking a digital camera down there and taking pictures. I did this constantly because it is not really possible to view by eye on the right bank cams.

If you do all of this and the problem continues, it is likely unrelated to the timing belt. Maybe tune-up related. Timing belt is all mechanical, but there is a lot going on with ignition and idle control too that is beyond a home do-it-yourself to adjust.

Thanks for the feedback 93fxdl and humphry. I think I was panicking at first because of the 'interference', and didn't want to destroy the wife's van. I think it is a lifter I hope. Got a friend that is going to hook up his scanner to it tommorrow. Will post something back on the results.

Default 2000 Carnival Timing belt info

Hi

I am considering taking on the task of changing the timing belt in my 2000 Carnival (Australian version of the Sedona).

Does anyone out there have a step by step accurate chart on how to go about this.

Also, is the information on this post relevant to my model, 2000, as the car you are talking about is a 2004.

Thanks

Rob:
I would clean the heads up at same time as doing timing belts.
Replace head gaskets as well.
For that age vehicle anyways. But check your vehicle history on Vcheck.
As its likely the engine was changed before ya got it?
And new belts fitted anyways....
But you really do need a manual. The alignment procedure needs to be understood.
Ebay sell the V6 gasoline 2.5L CD. The kia site no longer has the appropriate details for our Carnival engine from what I can see. Last time I checked.
(You need to access it thru internet explorer - wont work with other browsers)
Replacing timing belts fairly easy, just takes awhile, and hard to see the cam shaft belts,
Fiddly replacing those as well - check your final tensioned timing mark alignment with the centre popped back plates crucial.
As you can easily get stuck lifters jamming valves into piston heads.
The risk of stuffing something up is far more than the risk of a modern timing belt breaking !

It does pay to do them yourselves, as ebay is constantly full of vans up for sale after a
gasket/timing work. The big shops just rush thru the job, and everybody is human - mistakes happen. And the engine isn't tolerant of mistakes at all.

The carnivals V6 2.5 was essentially unchanged up until 2006.
So plenty of spare parts around. Just wreckers charge expensive for engine parts.

Re Carnivals:
The lower drive cog on crankshaft has varying alignment grooves, marks - changed over the years. From description, he appears ok with his alignment, Though confirm your LH & RH bank is aligned correctly, as a newbie mistake is to align the crank, but the top cam pulleys are out... Full rotation of crank.... As top pulleys have two grooves (interchangeable, left to right)

And watch the lifters though after any rework - they can seize - and main timing belt jump teeth. and you get valves/piston collision.
A borescope down the spark plug holes will show if all valves/lfters performing correct as engine rotated....

If vehicle seems to stagger or difficult to initially turn over.
You may have lifter/valve/piston problems. Check piston chambers internally with borescope..

Always important you manually rotate engine a dozen times by hand prior starting !
Valve interference !

Default 04 Sedona Timing Belt

I found it most helpful to secure the cam gears in place while changing belt. Drill two 1/2" CPVC couplings with a 1/4" hole from side to side at the midpoint. Insert a 1/4" x 20 x 4" stove bolt through the couplings and then a nut. The couplings sit in the "V" area between the gears at the top and bottom. With the gears on the timing marks, tighten the bolt.
