Default Cam swap question
I have a 2005 LS2 57,000 miles doing a cam swap. I’m replacing timing chain with C5R chain. Do I need to or should I replace crank and cam sprocket if no visible wear?

Plan on doing C5R timing chain kit. Just not wanting to do anything unnecessary. Also changing oil pump also. Anyone know on a LS2 if oil pan has to be dropped slightly to change oil pump?

My concern is isn't the factory oil pan gasket silicone? If so does dropping pan slightly cause any sealing issues when re torqueing the oil pan?

It's wise to swap the gaskets. Especially ones you don't want to change again...

You don't need to drop the oil pan to change the oil pump on a C6 LS2 car

If you had good oil pressure before and there is no visible wear, I don't see a reason to replace the sprockets.

Went ahead and ordered a complete C5R timing kit. Also have confirmed LS2 oil pan does not have to be lowered to replace oil pump on Corvette. Seems if an LS2 is in Trailblazer/GTO the oil pump bolt is on the inside flange and oil pan has to be lowered.

No you do not have to drop the pan at all to do the pump,
