This thread is about making lemonade. This 2015 Chevy Tahoe made it to just 77k miles before cylinder #1 stopped building compression. Come join us for a L83 AFM delete and cam swap in vehicle. Watch as we knock some reliability into this gen V motor..

 

 

Big shoutout to Jim and the great bunch at Cylinder Head Exchange for the great machine work. Due to our less than stellar planning we ordered the valve springs after the heads went out and so here we are swapping springs on fresh heads..

 

There are 2 ways to upgrade the rocker arms in a gen V motor. You can buy the rocker arms or you can buy the trunnion upgrade kit and install it on the rocker arms you already have. Here is a video demonstrating how to install the trunnion upgrade on gen V rockers..

 

This thread is about an in-vehicle camshaft swap and here that is. In order to make room for the camshaft to come out the radiator and fans were removed. The A/C condenser is still in place and the A/C system still has it's charge. My apologies about the poor quality from the low light at the engine block..

 

As we raise valve lift and extend the duration it becomes important that we limit or restrict the allowed movement of the VVT system or we might happen upon a PTV clearance issue. The BTR stage 2 camshaft we are installing instructs to add in a 4 degree limiter that gets installed inside of the camshaft sprocket also called the camshaft phaser. Here is that limiter being installed..

 

With the BTR stage 2 cam installed and the 4 degree limiter installed in the phaser the next step is to get the timing chain on..

 

Here we are getting the heads back on. Instead of the standard torque to yield hardware we are bolting the heads down with ARP hardware..

 

This Tahoe already has a CAI. To go along with that and the camshaft we just installed we are also installing Texas Speed long tube headers. Here is a side by side of both exhaust systems out of the vehicle..

 

We hurt the rails and injectors on removal. They just did not want to come out of the heads. So we must setup new rails and injectors for this Tahoe..
