Its not that tough. Just lube it up and slide it on the tube, put the tube in the bottom of the pump and squeeze with your hand. The flange should come together easily.

Found a picture of it. Definitely would save a ton of time on a future swap.

Thanks.

The chain damper helps control chain slap during periods of sudden engine RPM changes which reduces chain stretch and prevents wrapping which can induce chain breakage.

Don't know about being discontinued but I just ordered one from Fitchners and received it.

Give them a try. Make sure you order the one for the C5. The C6 one wont fit. If your block has the provision for it,, why not install it.

The POWER BOND Dampener is the Harmonic Balancer mounted on the crank shaft. Its a quality piece.

Thanks.

I used a length of small diameter rubber hose. The hose slips easily into the sparkplug hole. When you rotate the crank to get the piston to TDC the hose is compressed by the piston and you can no longer 'tug it back out'. Actually, 2 pistons will be at TDC at this point.

As Pewtvette says there are actually two cylinders at TDC. I don't rember the exact order but someone will post it. Therefore you can change the springs on two cylinders then two more so on and so forth. It actually speeds the job up and in my opinion a much safer way of doing it with the heads still on the motor.

Oh, it's when replacing your springs (spring upgrade mandatory with new cam). You don't want to drop your valves into your engine. Top of piston keeps valves from dropping into the cylinder (as long as piston is somewhere close to TDC). The hose or rope simply let you know when the piston is at TDC. Please excuse the over simplification.

You wont! I didnt think my 02 ZO6 had the holes (I was willing and planned on drilling and tappin the holes). If you tear it down and have the holes, order and install it.

Simple as that.

It's the "NUTS" tool. It is pricey but it saves some heart ache because the tools that use a piece of plate steel and lever themselve off the side of the head and are screwed down with with a stud in the rocker bolt hole can break that stud off in the hole or damage the threads in the head. Both outcomes are not good.

If possible post up on here and see if someone will let you borrow the tool. Brian (Cobra4b) comes to mind he has the tool I believe and might lend it to you.

You are in FL and the best price on that tool is in Orlando (Vinci).
