Title: Twin Cam inlet camshaft
Post by: Sherman Kaplan on Friday,November 16, 2018, 05:35:28 PM
Is there a setscrew to seal the end of the inlet camshaft on the Twin Cam?  I have a setscrew for the exhaust camshaft, but nothing for the inlet.   The setscrew for the exhaust camshaft does not fit in the inlet camshaft.  Is the inlet camshaft sealed by the bolt for the alternator pulley?   The parts manual only list one setscrew and shows it going into the exhaust camshaft.  The parts manual does not show anything for the inlet camshaft that I can see.

I was planning on using Permatex thread sealer on the exhaust set screw and the alternator pulley bolt? 

Thanks,
Sherman

Oil does not come out of the inlet camshaft with the pulley and bolt removed.

Thanks, so there is no setscrew, only the pulley bolt.    Do you think Permatex thread seal is a good choice for the exhaust camshaft set screw and the alternator pulley bolt?

Thanks,
Sherman

Interesting! I don't have a TC but a BDA built by Dave Bean. He modified the inlet cam to accept an alternator pulley and oil WILL come out if the central bolt holding the pulley on. Obviously, this isn't meant to relate to a TC but I find it a little ironic that my inlet cam will leak oil without the center bolt but the TC won't!

Is the cam centre drilled with small holes to each cam to oil the tappet where the cam meets the cam follower bucket on the head?
