My SA200 is leaking oil from front and rear seals. Will probably put an
additive in there, but am not expecting a lot. Has anyone rebuilt one of
these four bangers? Doesn't look like anything complicated. I've rebuilt
about half a dozen V-8's in my life, the old 283/327 Chevies. Parts seem to
be available, probably even from NAPA.

Ideas appreciated. I know it will cost a bit, but compared to a new one, it
will be less, and I like this old gal. If the back half checks out, I may
spring for it. Get a new circuit board, too. I'm guessing $500 for full
gasket kit, bearings, carb rebuild. More for machine shop work. That might
be another $500, but I think less unless it needs to be bored, and it
doesn't smoke. Anyone know the real price who did one of these?

Bill's specializes in SA200's and they want $1600. Plus it is in OK City,
OK. I figure half or more of that is labor.

It's running now, just leaking, so there shouldn't be any big ticket items
for catastrophic failure items. Exhaust doesn't smoke, no oil in radiator
water. Haven't done compression check yet. Maybe have the crank turned and
go with oversized bearings. Do a compression check, and may or may not put
new rings. I figure it's apart, why not. Hone the cylinders and check for
tolerances, break the top ridge. Valve job, and new inserts. Carb rebuild
kit. And put a new muffler on that loud broad. Repaint. Maybe a decal
set, and a new faceplate.

TIA

Thanks. Good manuals. I couldn't find what the compression should be on a
compression test. Anyone?

I don't have the manual but I'd be happy with around 110 psi or so. Even
across all is more important. And for any engine used under continuous
load, I'd expect the valves to be quite burned. I know you LOVE spending
money but new seals and a valve job might make the old baby run for a
lot of years at far less money.

Indeed

And thats what most of the oil field welders around here do every 4-5
yrs

I like that. Take it to the machine shop. Pick it up. Slap it back on
there. Quick and easy. Steve W suggested that I might just change the
front and rear seals without having to totally disassemble. So, we'll see
which way to go. I got to do the compression check first, and that should
tell me a lot.

These are simple very low tech engines and are not difficult or tricky to
repair or rebuild, but I would advise against 'overfixing'. They are low
speed engines that will run for a long time if given clean oil and coolant.
I have rebuilt several of these, some of which were very badly damaged.

IIRC, Your old Sally has done a lot of sitting around and no doubt the seals
are getting hard and maybe brittle. IIRC the front case cover is aluminium
and also is the front engine mount. One of my machines developed a front
leak that I thought was from the crank seal but turned out to be a cracked
case cover. I probably could have welded up the original cover but the
crack was in the high stress area of the mount and I was able to obtain a
new (maybe used?) cover and new seal which seemed like the better option. I
kept the (unrepaired) old cover 'just in case'. IIRC, the front seal was a
common one piece circular rubber lip type.

IIRC, the older engines used a jute packing in the rear main seal but
suspect that later engines use a two piece rubber seal similar to the two
piece Chevy engine rear seal. I would expect yours to be the jute type.
The seal is mounted in a removable lower filler block but I cannot remember
if the upper seal is mounted in a removable block or in the iron engine
block. Replacing these jute seals is easy with the crank removed, but I
think it is possible but more difficult with the crank and weld generator in
place. I suggest you will need to remove your pan to see what you have. At
this time you will probably want to check the condition of the main and rod
bearings and roll in a new set if required. Some people have had good
results by just changing the lower jute and trimming it a little long and
carefully compressing the upper seal using a plastic or wood tool so as not
to damage the crank.

I am not a big fan of leak stop additives and IMHO they really only work in
machinery with these jute type seals. I doubt they will help your front
seal problem but may help the rear seal.

If you are not burning engine oil and/or making smoke (after warm-up, lots
of these engines smoke a bit at start-up when cold, and will continue to do
so for years) then I would not bother with cylinder or valve work. You
should do a compression check with the engine warm and cylinders dry then
again after adding a couple of squirts of oil to better seal the rings and
give you a good check of valve sealing of compression. Don't be too
concerned about the actual compression measured but rather pay close
attention to the variation between cylinders and between dry and wet tests.
If you have access to a bore scope then have a look in the cylinders
(through the plug hole) to check for scoring and compression ring sealing or
blowby.

If the upper end checks out then I would just reseal the crank and check the
crank bearings and hopefully not even need to remove the block or the
generator or the crank. This will all be a lot easier if you can drain the
liquids and roll the welder so you are not doing all the work overhead. A
hot roder's body roll frame would make this easy and you could make one
easily out of old pipe or get an electrician to bend you one out of
electrical conduit. They are very handy for any type of positioning.

Good luck, YMMV

IIRC, we used to use PlastiGauge to check the journal wear. Is that still
standard?

PlastiGauge is not as accurate as we would like to believe, but is better
than nothing if used correctly, and it will make you feel better. The crank
must be held against the block side or the readings will not be accurate at
all. If the engine is inverted this is easy as gravity is working for you,
but if you are inspecting overhead then the crank must be held up against
the block with a jack.

IMHO, PlastiGauge is best used as a final check to catch big problems like
installing the wrong sized shells. The old shells should be size marked on
the underside but you need to mike the crank to check for regrind size.
Usually? you are safe just installing the same size that came out but if you
want to install .001 undersize then you had better mike the crank and the
block and the rod bearings and not depend on PlastiGauge.

Continental cautions that " TC and Y crankshafts MUST be nitempered after
regrinding." I am not a big fan of routine regrinding unless necessary.
(KISS, I also prefer plain cast iron rings when re-ringing as they will
break in much easier and are much more tolerant of bore finish.(and are
cheaper))

IMHO visual inspection is the best indicator of not only wear but also of
prior maintenance quality. Visual inspection can also show evidence of
fatigue. Main bearings are easy to inspect visually because most of the
wear is likely on the cap side but con rods are the opposite as the loads
from both the compression and power strokes are on the rod side. The wear
patterns can also tell you a lot about alignment. In the big picture
bearings are cheap and easy to roll in. Some people do not like to
reinstall bearings as they claim the required crush has been compromised.

Cat truck engines recommends rolling in new main brgs @ ~500k as routine
preventative maintenance, as the upper engine will outlive the bearings but
bearing failure usually scraps the entire engine. Diesel engine bearings
are a lot more heavily loaded than most gas engines but the thinking is
similar. Your Continental will run for years with leaky valves and rings as
long as it has clean oil and coolant and the crank does not fail. Lots of
welders run for years but need to have one or more plugs cleaned of fouling
periodically when they start miss-firing.

It will also run a long time with leaky seals as long as you keep checking
the oil and do not run low. Do not lengthen your drain intervals very much
or at all. A catch can strategically placed or hung with wire can solve a
lot of messy type problems if the leak is not too severe (and you do not
need to worry about getting oil on a clutch disk) but you should carefully
inspect the front gear cover for cracks at the motor mount.

Good luck, YMMV

It is cloudy outside, and drizzly. Tomorrow it will be a high of 32, and a
low tonight of 13. I think I'll wait a couple of days to go check anything.
My BIL brought over a forklift assembly for me to weld yesterday, which was
when I noticed the leak. I'll just keep it full of oil until I can figure
out what's going on.

It might tell you if you have bad valves..that is an L head engine.

One of these....
