: I rebuilt my 318 V8 a couple years ago and the
: cam shaft was tight, too tight to let it go
: that way. I could see where it was tight by
: the marks it left in the cam bearings.
: Especialy around some of the oil holes and
: the edges of the bearings. I used a
: triangular scraper to carefuly scrap off the
: high spots in the bearings. This is much
: easier to do without the crankshaft in the
: block. It takes a steady and carefuly guided
: hand to do the scraping. Now over 10,000
: miles later all is working well. I don't
: know where to tell you to get a triangular
: scraper. Mine is a Nicholson brand (same
: place that makes files). I've seen others in
: catalogs over the years. Try your machine
: tool or industrial tool suplier.
: Scraping bearing was a common task many years
: ago in the days of poured babbit bearings.
: Good luck.

: I have also had this problem and actually took

: This sounds like the best tip so far. But, with
: the #4 journal being a little undrsized,
: will I lose oil pressure to the top end?

: I made a puller to install cam bearings a few
: years ago. I cut the journals out of an old
: cam and then welded washers on one side of
: each journal-to form a "T" shaped
: plug. I drilled a 5/8 hole thru the center
: of each plug.
: I used a 3' piece of 5/8 threaded rod as the
: pulling device, using an old valve spring to
: cushion the load as each bearing was drawn
: into its bore.
: I found that you can maintain better alignment
: of the bearings, as well as the oiling
: holes, by using this method. There's much
: less chance of distorting the bearings this
: way too.
: Anyway, the newly installed camshaft could be
: turned by hand with minimal effort. I've had
: machine shops install bearings that didn't
: work this well (they usually drive them in
: with a hammer)
: Hope I've been of some help.

: I did something similar. I used washers for the
: plug, loose but did a pretty good job of
: keeping the 5/8 thread rod centered in the
: bearing. Also, I did not use a valve spring.
: Mine went in with no muss or fuss too.
