Cam Replacement

[Dick Little]

Out of curiosity, where does one find an XPAG crossflow head?Probably in the same aisle as the box of hen's teeth! I have an MPJG in the TA, so a crossflow head would be at least two orders of magnitude more power.Dick Little TA1326

Just so you know, the radiator has to come off and the front motor mounts have to be removed before you can jack up the engine to remove the oil pump. To answer some of the questions. The engine has less than a 1000 miles on it since being built. It has Len s roller cam, billet crank, Saenz rods and J&E pistons. It s a later TD engine with the later TD oil pump and yes, the pump was rebuilt using Moss parts. The gear is held on by a solid pin, not a roll pin. I am expecting to have to replace the cam but the reason I don t want to pull the engine is SPACE. The garage space it s in is barely longer than the car and I don t want to move it to the larger garage because I don t want to leave my wife s car outside until I finish the job...that s why I was asking about doing it with the engine in place.

I wonder if 3d printing could be used to generate a usable core, based on modifications of scanned data derived from the standard head (e.g. stud/water passages, combustion chambers, valve centers, etc....)?   ----pps

Len probably nailed it...I found part of the circlip in the recessed portion of the cover above the driven gear.  The remainder of it is probably jammed between gear and the side of the pump.  If so, I ll be needing a new oil pump...anyone have one for sale...with a good circlip! 8^) Thanks,Gene Sent from my iPad
