3.5 TDC position
I just want to make sure I got this correct before I disassemble the timing case... came across quite a bit of set backs already and I dont want anymore... Do I have the engine at TDC?? I dont really want to take out #1 coilpack cuz it looks like I have to undo the intake mainfold.

Jacking the thread because I didn't want to start another one. I finally got time to work on the 3.5 again and I just wanted to make sure I got the timing right. I know I don't have the colored links lined up on the inner sprocketsb but they are right.

so all you have to do is line up the arrow to the darker chain link?
and to get the engine to TDC line up the chalked areas? those marks dont look very "exact" its kinda just a little chalk mark.
also, why does it have to be at TDC?

Yes you will line those up. when installing the 3.0 equipment on, dont just go by that arrow and the link, look at the cams as well make sure the lobes are aimed properly. And look at the crank also to make sure its lined up at TDC.
Chillin... TDC is a good point of reference for when your installing the timing equipment. If you just didnt set tdc, and tried to put on the new timing equipment, say you move the cams by accident or too far, you would have no way to get back to exactly where you were. TDC is a good point of reference, you accidentally move something too far, you can set everything back to TDC, and continue. Wouldnt want to start the car up and you have valves slapping into pistons and such . . . ouch.

Would any of you suggest using locktite to secure the the cam spacers/adapters? I dont think it would be necessary but my brother was suggesting it.
He was thinking of putting a little in the hole where the dowel pin goes inserted. Have any of you done that??
I honestly feel theres no need to because it will be secured between the camshaft and the pressure of the cam gear. Plus, I had some adapters made out of steel... nothing wrong with Stephen Max's adapters but I feel more secure having a steel spacer(base) to hold the dowel pins.

they relocate the dowel pin... its the same exact dimensions as StephenMax's but mine are made out of stainless steel. I bought StephenMax's to make sure I had the right dimensions and just had my friend make some for me at his machine shop. So once I finish the swap, I'll re-sell the ones StephenMax sent me.

four spacers are needed. I also want to know if people are actually using a degree wheel to help them set TDC with the cams. And if so, does anyone have a degree wheel they recommend.

a degree wheel isnt needed to set TDC. a degree wheel would be useful in drilling the cams.

I dont know if he would make just one set... its real time consuming to make them. I actually thought about having him make me a few sets so I can sell them. If I decide to do so, and if he's willing to do it, I'll let you know.

Ok I'm assuming this is about the vq35 cam swap...If so is anyone planning on doing a write up with pics? Not that I'd be doing the swap myself (shop would) but I would like to see whats going on.

the sticky provides many pics and pretty much all the information you'd need to know for the swap. there are a few small things here that werent included but the big issues were tackled in the sticky.
