You didn't buy a car Ang, what you did there was buy a boat.

 

Lol I love the boat ride of older ford and chevys. Screw handling I'll take a soft ride and serious bodyroll any day!

 

I might just put Lambo Doors on this one and then sell it off as a Land Cruiser Special...
Only has 57,000 miles on this one..Lil old man owned it and a 1 Owner of course...

That's a nice deal with only 51,000 at any price, too bad gas doesn't cost what it used to.

 

They're both operated by oil pressure, but the switching comes from the computer. Even back in the '90s on B-series engines. The ECU tells the VTEC solenoid when to apply the oil pressure to "turn the VTEC on".

The K-series iVTEC engines can also advance/retard cam timing (continuously variable) in addition to activating the VTEC cam.

 

Yeah I read that in my hanes manual a long time ago. I know I'm probably wrong, but I assumed the only way to retard or advance timing was to move the cam shaft away from the rocker arms, or move it closer to advance the timeing. How far off am I?

 

There are a few ways to do it: rotating the distributor (F22 and older), custom ground cams, adjustable cam gear, manually rotating a cam a sprocket forward or backward out of time with the crank, etc. The valves still open for the same lift and duration, with the exception of a custom ground cam, it's just changes the relation to TDC in degrees. Base timing on an F22B2 is 16*BTDC I believe.

 

Rotating the distributor won't do anything for cam timing. Besides, I'd like to see how you propose to rotate the distributor on a K-series engine. (Hint - it doesn't have a distirbutor)

Cam timing is adjusted by a funny adjustable sprocket (#7) that operates by oil pressure from a control that's ultimately driven by the ECU.

 

That's why I said F22 and older hehe. Even on the F23, you can't rotate the distributor to adjust base timing.

 

K-series ftw.

k24a4 only has vtec on the intake cam.......or was is the exhaust............no I think its intake.
