Built new head now need help with timing marks

[Napster]

OK, I got the head back from the shop today for the second time sense they lost a cam cap last time...long story, anyways i installed the cams in the head and i went to line up the cam gears before i install the head on the black and this is as close as I can get. Is this okay.

Also my comp cams didn't say straight out whether it was for exhaust or intake but the part number for one ended with an E and the other with an I is this a good assumption?

No, that's not correct. If you look at the marks, they should line up straight across, as well as with the valve cover surface directly behind them. It looks like they both need to be rotated inwards a bit, then put the timing belt on, put on your clips, and let them go.

 

[Napster]

Okay This is the closest i can get with the belt able to go on and i dint have to clip it it stays there pretty well.

Mark the center of the cam sprocket bolts with a sharpie. Put just a dot in the middle of each one. Then, take a ruler and lay it across the bolts and align it with the two dots. The marks on the sprockets should align with the ruler.

If you dont have clips, twisty ties work pretty good too. Thats what i used when I my timing the last time. Theyre just to keep the belt on the cam gears while your putting the belt around the tensioners and crank sproket.

Okay i think I got it down to a T now , But does it matter witch marks line up, because now its backwards as it was before but strait, if this is a problem i can turn it make around.

Intake cam will have a little retangular shaped mark above the slots where the tang of the CAS goes. This mark is to be above the slots to be in correct timed position.

Those marks look good now. I'd throw up a picture of all 4 marks with a straight edge just to be sure, but I think you got it.

What do you mean? are you saying all 4 marks on the cam gears should line up?

If i'm not mistaken you are 180 out on both cams. Look at the FAQ and you'll see that the timing mark with the groove cutting through the middle of the sproket tooth should be the intake side, and the groove for the exhaust should be cutting the half moon portion (where the teeth of the belt itself seat) of the cam gear. If you can get it that way, you should be able to get it the right way! If not, your going to bend some valves... aske me how I know!!!

On comp cams both the intake and exhaust both have slots. I don't know why.

Crap! you got two INT cams there ...!!

Yeppers - you're 180* out for sure on both sprockets.

Look at your first pict-see the cam's alignment pin (right above the bolt) on the EXH sprocket at the 12:00 position? The INT has to be at the same 12:00 position ...

They are two diff part numbers so i don't think they are the same but they may be. Is this an issue, also i have both of those marks at the 6 o'clock position.

Those cam gear marks are good.. You want the dial pins up when your timing it, so your good now!!!

is it a problem that they both have a cas cutout, they don't have the same part number, one ends with an E and the other with an I, I just took that for exhaust and intake...

 

[talondave]

Your good mine have the same thing.. E=exhaust and I=intake...

 

[Napster]

thanks I was worried for a bit. Thank you for all the help guys, I mean it!

 

[Rob10_99]

Just remember pins go up on the cams, that could have been bad!

 

[DSM1G90]

That Exh is still a bit off - slightly higher than the Int - readjust the auto tensioner and those marks should be dead even across from each other and across the top of the head.

Good luck - DSM
