Quick & easy homemade Porsche P237 camshaft tool.
All you need is a welder, a 2 1/2" length of 2" I.D. black pipe, a foot or so of 1" black pipe and 3 bolts. Picked up the materials at Home Depot.
Cut out a section of the pipe to fit past the chain tensioner:
*** Before proceeding block off the oil galley with some paper towels so you don't drop any parts into the engine***
I made some pins from some bolts I had in the garage (sorry don't know what size - something that fits reasonably snug in the sprocket holes):
Place the pipe over all 3 bolts and clamp 1 down with a needle nose vice grip:
Weld the first bolt to the pipe. Return to the cam, line up the second & weld and finally the 3rd.
Tack the short piece of 1" pipe across from the tensioner cut-out and you are done!
Shout out to "Squidmarks" for the inspiration.
