First I have heard/read about the dowels not doing squat.....
I don't want to spend more than I have to for one intended cam swap, but if needed to save me from lifter fishing, fine.

Thanks for the offer Beau.

Like he said, heat it up and it'll slide on with ease. I actually put mine in the oven for about 30 min. and it went on as if astroglide was involved.

just make sure you have the correct pulley puller..otherwise it will take you hours....as far as springs do you have a compressor with a fitting for the sparkplug holes if not get one it helps...
you can buy a brand new crank bolt at any dealership i think i paid 5 bucks for mine...you can use the old bolt for turn the motor over to get everything lined up before you finish putting the timing gear/chain back on...

also take a piece of tape and put it over the small lip of the oil pan once you get teh timing cover off(trust me just added insurance, i dropped a bolt in there and it took almost an hour and a half of fishing till we got it out)

and pen magnets are your friend

Let me draw you a picture...literally

The left pic in the drawing is the JPR tool(the green semicircle blob)...you see it's a semicircle that engages the notch in the lifter. The dowel(the green circular blob), in the center pic, does not. The far right pic is a dramatization of what can happen if the lifter falls while the dowel sits back and watches. I have no idea what happens when a lifter falls...but I thought for entertainment purposes I'd include it



This is a pic of the camshaft location...you can see the tips of the lifters hanging and the oil journals at the top right and top left corners of the pic. The red circles in my drawing are those oil journals where you stick the JPR tool.


This is what the lifters look like and you can see the notch



Again, these are my observations and you don't have to take my word for it I've seen the JPR tool in use, I've seen how the lifters cross those oil journals and that's when I went and bought pen magnets to do my swap. Let me know when you're doing it and I'll see if I can swing by

Intersting Colby, thanks for the picture. My guess is that the effectiveness of the dowels would then have to depend on the diameter and whether or not they are able to exert any pressure on the lifters. I will consider the JPR tool.....but we'll see.



Zzebes.....college station isn't that far but I can probably piece together the bits I need.
