What did you do today to your 3/S?

I had decel exhaust popping last spring but it was because my TPS went bad. It wouldn't read low enough to put my car into decel fuel cut. However your wideband being 18 means it is probably not that.

Got this today.

Need to replace my broken power antenna.

So setting mine initially to the 3sx ones was completely backwards...:facepalm:

My block and heads are completely stock. No machine work to the heads or decking was done to them. So I never degreed them. For now I'm just going to move them all back to zero and see how it runs. Should have it all done in the next couple days.

The only way to verify zero is actually zero is with a degree wheel, solid lifter, dial gauge, and a piston stop.

That comment was in regards to the findings made a year or so ago about certain 3sx and some Fidenza cam gears being a couple degrees off from the start. I verified the ones I have are not off by matching them up to a stock cam gear and ensuring the zero mark matches up to the stock cam gears, which they do.

Got my rear mud guards installed!! and while I was in there with the wheels off, I inspected the pads and cleaned up and re-lubed the calipers with Permatex Ceramic Extreme Brake Parts Lubricant.

The cams still aren't "zero" on your engine unless you degree them. If they are degreed it actually doesn't matter if you have ones marked correctly or incorrectly as the cams will be set correctly through the degreeing process regardless.

Are you referring to the actual cams or the Cam gears?? I'm taking about the cam gears... They are exactly the same stock vs adjustable and the zero mark used for setting timing is the exact same place on both. So setting my adjustable back to zero would be the same as swapping the stock cam gears back onto the car.

Assuming you were able to get them to match stock cam gears within a degree or less does not mean your cams are where they are intended to be if you have done any of the following: different cams, resurface block, resurface head, different HG.

Adjustable cam gears are first and foremost to set the cams to where the manufacturer intended (OEM or cam card of aftermarket) and second to adjust the opening/closing timing and overlap to suit your mods and desired powerband.

This is accomplished with a piston stop, degree wheel, dial indicator and solid lifter. Takes a little time but worth it. Especially on a DOHC V engine with two sets of cams.

Stock cams, Stock heads and block. No surface work done to either. Stock OEM Head gasket. So the zero mark on my Adj cam gears should be in theory the same as what my stock cams have. or am I missing something....

Should be good.....So why not run stock cam gears?
