Andrew: I think I messed up a lost the reply re. towing so i send
again more briefly.
Your tranny does not lube the rear bearing when towed on the ground
in neutral gear. This bearin is ONLY lubed when engine is running
and countershaft in bottom of tran is spinning.
Many cars towed to me with siezed tail shaft bushing and damage to
housing as well as to the output splined coupling.
OK to tow below say 30 mph for 10 miles or less. More than this you
must remove the drive shaft (put a baggy and rubber band on tail
shaft to catch oil) or town with rear wheels lifted.
The above applies to a great number of other types of vehicles and
because few mechanics or even service managers seem to be aware of
this damaging situation I suggest you phone up your appropriate
marque "zone office" and speak ONLY to a technical service rep.!
Owners manuals tend to gloss over this subject with a blanket remark
about not to tow etc.
Both manual and auto trans are subject to this sort of damage so make
the call.
Four wheel drive vehicles need to be also checked with the mfr. as
they have potential problems as well.
If you MUST flat tow a longer distance..... stop every 10 miles and
start the engine and allow to run about one minute, then resume your
tow. This will oil up the rear bushing and prevent damage in your
Sunbeam.

Jarrid; something is causing rapid wear in some part of the valve
train which causes you to have to make such frequent readjustments.
I cannot believe this is from pushrod settling into bottom of lifters
because I NEVER see this happen. Also you get the problem across all
valves I believe.
I never saw any heat treatment visible on rocker arm tips, such as
blue or other heat colors. My prior remarks remain as stated. The
tip of the rocker "wipes" across the valve stem and with normal oil
there is little wear until extreme high milage.
As you know, when a cyl. head height is changed by milling down this
changes geometry on the rockers. Basically we want a 90 deg. angle
between valve and stem when valve is open 1/2 its lift. Anything
which alters this by much will contribute to abnormal wear pattern.
My prior comments re. push rods fitting into lifters without wear,
remains my opinion on this subject.
The Series V crankshaft is 5 main bearings and is forged steel, not
cast iron, hence my remarks.
I sold three trucks of parts of parts to a Denver co called Scotland
yard years ago, then gave the rest away a few months ago to a friend
in AZ.
