Timing chain to Oil pump clearance???
Timing chain to Oil pump clearance??? How much clearance is there supposed to be between the timing chain and the oil pump? I'm installing a double roller and a ported TSP pump with the rollmaster aluminum spacers.
Any other clearance problems? It's a 98 Z-28. I've heard of timing cover problems.... on Vett's??

I think the more important question is how how off are the crank gear and cam gear from each other? IIRC, the difference should be less than .010". I'm really interested to find out if those that have broken double rollers have actually checked this "run out" before running the motor.
The double roller should have came with shims to shim out the pump.

How do you check or adjust the crank to cam gear alignment? I seated the crank pulley all the way... by hand, then I put the old gear on the snout and gave it a few taps to be sure it was seated.
If it came out any farther than the chain would hit the pump, and it can't go back any farther!
I did use the spacers provided by rollmaster for the pump.
Did you modify the pickup in any way?
Thanks

You got it right. Everything should line up. Just take a look from the side with the chain on. It should be straight top to bottom. Make sure that your cam gear is fully seated on the end of the cam. Sometimes they get stuck, and don't go on straight.

I didn't have to modify the pick up at all like others have had to, but I did purchase a new pick up as I pieced my motor together.

Did you have any clearance issues with the timing cover?
I realized that I was having clearance issues with the timing cover, on an F-body (don't know if that makes a dif.). I did as SpeedyZ (from Corvette forum) suggested, and put on the cover w/hand and moved it around, then ground off the part that looked like it was rubbing, I MOSTLY did the grinding on the pump though.
I used a sharpie and marked the THREE touching areas (on the pump and the cover) then rubbed and then ground. Took quite a while, I removed alot of material. I hope the double roller is worth it. Kinda wish I'd just went with the LS2 chain. O-well, hope it all works out!
