The ye old gasser cam swap
« on: April 13, 2012, 11:26:59 am »
Im sure some of you have heard or the gasser cam swap. The story usually goes to something to  the tune of timng belt snapped and a gas camshaft was installed. After the swap the car had lots and lots of power. I know the later 1.8 camshafts would make the valves hit the piston, but what about the 1.6 and 1.7 gas engine camshafts swapped into a mechanical diesel head?

pretty sure NO GAS CAM SHAFT works..

they have no tapered snout. and you cant get a diesel width timing gear with an 8v gas cam sprocket center.

so, ive never figured this one out.. rather than someone found a GASSER with a DIESEL CAM installed, and used it, thinking it was a gasser cam.

it cant work correctly.. besides, gasser cams have soo much valve overlap that the diesel valves would be injured..

There is no benefit to a different cam. Unless it is a Dr. Diesel custom ground cam.. Cams in gassers increase the lift and overlap and what have you.. there is no such room to do that in these engines when the pistons and valves are chasing each other with just a few thou between them.

not to mention gassers DO NOT HAVE A TIMING SLOT on the back side of the cam needed to get perfect valve timing
