cam swap
 

ive heard two different things on the matter
1. i would have to remove my engine to slide out the cam shaft
2. i would not need to take the engine out, the cam shaft does not need to slide out in my motor (m42)

i know its expensive for ~15 horsies, i was just wondering which is true
thanks much

You don't need to remove the motor, the cams come straight up. (There are two). Look at pelicanparts.com for a writeup.

To really get the most out of a cam its worth having a
knowelgeable person degree the cam(s) in.

My engine gained 5hp just by this little act. Cost between 1 and 2 hundred. depending on the hours required, and if you have it ready for him to work on...

thanks guys
pdxmotorhead, i'll look into what you said. seems more reasonable than the $500 - $1000 it would cost me for new cams (bavauto being my resource there)
thanks again

Yea, when I rebuilt my jeep engine the builder assembled it for me I installed it and he had degreed the cam originally, but after I got it running he fine tuned it and it made a nice gain. (5hp) We did this trying to slide as close as possible to the peak power and still pass emissions testing....

Of course on the M42/M44 engine its hard to say how deep he needs to get to get at the cam drive sprockets.

You might need new cam gears to truly adjust it...
Which I would only do if I was putting in a new cam...
Sometimes it just takes offset keys to get a cam "in".

The m42 has stock adjustable cam gears. All you need to do to get to them is remove the valve cover.

This is true.

interesting... this information could be useful
thanks

What about tuning the M44 cams? I haven't seen the motor without the Valve Cover Plate though.

The M44's cams aren't adjustable.

Funny I'd only seen a M44 apart and assumed the M42 had the same setup.. :) and I own one... :redface:

Its worththe hassle any time you install new cams to do the whole job, degree em in. It pays back later....
