2006 Timing

[nstoolman1]

I need to keep turning the sprockets on the head of the cylinder(#1)that is TDC until the marks line up,

Yes. Then it gets tricky. You then install the belt and slowly turn it until the next cylinder in the firing order gets tdc. Check to see if the valves are closed. If they are slowly move to the next and so on. If 2 are aligned chances are you are good. Once you have done that continue turning the engine over by hand and recheck your marks with #1 at tdc.

You not going to fing believe this!! I had a sneaky feeling and took off the valve cover and there lies a bigger problem..... Bend valves!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Dang it!! So The valves on passenger side head closest to the fender are bent and the valves on the drivers side closest to the fender are bent. I am going to have to order 12 Intake valves.... Man this is a huge lesson learned.

I just finished replacing the timing belt on my 2003 sorento,last week. what I found,was they tell you to line the timing marks up, & rotate the engine thru two revolutions & see if everything lines up. what they don't tell you,is when you go to put the proper tension on the belt,is that all the marks will be off one tooth. you have to set everything one tooth off, to get alignment with proper tension on the belt. this is not as easy a job,as everybody thinks, & believe me, it was scary when I turned the key to start it ! either I saved money or destroyed valves ! Started right up ! what happened with me,is when your trying to get it right, the passenger side sprockets are under pressure & will spin. As you put on the belt,zip tie it as you go, so things won't get out of hand. Hope this helps !

Sorry to hear that. Each time I read that you spun the engine I kept telling myself "I hope he doesn't bend a valve". Lessoned learned. When you put the heads back on do one at a time. PS #1 first then DS #2 next. If those 2 are installed in order the rest should follow suit. Keep us posted.

I have to order the valves so I can take a break for 5 days... Let me ask you a silly question What do you mean by PS #1 then DS #2? My mine just can't wrap around what that means... I know stupid ain't I.

[qwikbird]

he means passenger side# 1 -ps1. then driver side #2- ds2. sorry for your trouble,but if I had t to doover, I'd spend the money,& let the dealer do it !

Yes. And no, your not stupid. Frustrated maybe.


Don't forget you may need to lap those valves before you stick the heads back on. Lapping them in helps the seats match the valve seat.

Ok update, Got the valves in and heads put back on. The book states to put #1 cylinder at TDC (compression Stroke)? I know that you have to rotate the crank 2 times to line everything up, but i aint rotating nothing until I'm sure that everything is right(lesson learned) So how do I know what the compression stroke is? I read that you can have it off 180 degrees. What I did is rotated the crank until the #1 came up to TDC and the marks lined up on the crank. The way I think is when the piston is coming up is the compression stroke, is this correct?

Again Thanks for all the help.

[nstoolman1]

The piston comes up two times in a 4 cycle engine for one fireing cycle. That being said, with the #1 piston up and the marks on the crank and the block lined up you are at TDC compression stroke. I would have done that prior to the heads being installed to prevent "tapping" of the valves. If you did that then I misread your post. After the marks are lined up and before you install the heads, turn the cams so that the #1 cyl valves marks are lined up. The valves for that head are then ready and out of the pistons way when you gently install the heads.

[dixiepaxton]

Yes, I did put the #1 at TDC before I installed the heads, and the mark on the crank was lined up with that mark. I could not line up the cam marks because the marks to line the gear up to is on the valve cover. The only thing I am worried about is that the crank being 180 degrees off. Correct me if I am wrong but like you stated above the 6 cylinder rotates 2 times in one firing cycle. One is power stroke and one is compression stroke correct? Can the #1 piston be at TDC on both strokes? If so I need to make sure it's on the right one before I line the camshaftes up with there marks and install the timing belt.
