Tools and parts you will need:
- High-lift jack
- Medium- to high-lift jack stands
- 2 wheel chocks
- 10mm, 13mm socket and box wrench, extension, ratchet, and a swivel
makes life easier but is not required.
- WD-40 or similar
- razorblade (to scrape old gasket)
- NEW paper oilpan gasket and ultra grey sealent (Paper gaskets wont
seep like the cork ones do). They are available at any independent shop
but will have to be orderd. I can get them if you can't.
- A solid 6x6 timber to go across the shock towers and body molding
(make it a longer then you need so it won't slip). You should be able
to use a 4x4 too, but this depends on how much you trust the lumber
and/or value your life.
- Some scrap 2x4s about 8" long
- A piece of chain and 2 strong bolts with nuts and 4 heavy washers
- A can of brake cleaner
Procedure:
OK pull the car onto some nice, level concrete (safest materal to work
on) and chock the rear wheels (and use your e-brake). Drain the oil. While
its draining pull the nuts off the engine mounts.
Remove the distributor cap (mark were its suposed to line up) keep the
wires attached. This prevents the cap from brakeing on the fire wall when
lifting the engine. Connect the chain to the REAR pickup point with one
of the long bolts.
Lift the car on the center lift point (front sub frame). set the jack
stands and remove the 3 bolts holding the end of the down pipe to the
center section of the exaust. If the sealing ring isn't cracked, it can
be re-used. Now you can pivit the engine without damaging the exaust.
Drop the car back down some so that you can lift the engine higher, more
easily.
Take your high-lift jack and put the 2x4 on it. Line it up sidways on
the oil pan, i.e., across so that it passes beyond the sides of the oil
pan. this prevents damage to the oil pan when you lift on it. CAREFULLY
lift the engine with the jack. WATCH that the fan does not damage the
radiator. Your rad hoses should have enough flex in them so you dont have
to remove them. On one of the 2 cars I have done this on I did pull the
fan off as it was going to hit.
Depending on your jack you may have to stop and attach the chain up and
over the 6x6, now siting across the shock towers & fenders, and run
the chain to the front atachment point (install with 1 bolt the other
being on the rear). Watch that you dont lift too far and damage the fire
wall or slip off the oil pan. I always stop perodicly and adjust the chain
on the 6x6 as a safety measure.
OK now that the engine is lifted and supported by the 6x6 you can jack
the car back up and return it to the jack stands. Now it makes sence as
to why I had you drop the car due to the angle on the engine doesnt it.
At this point stop for a drink (preferably non-alchololic), while you
are at it get me one too.
Next, undo all the 10mm oil-pan bolts. You will have to fenagle the pan
down around the front subframe. If you have to you can drop the front
subframe (17mm bolts) but dont let its weight be supported by the hardy
disk (rubber disk on steering box).
Clean up the mating surfaces with the razorblade and wipe down with some
brake cleaner on a rag. Clean the oil pan itself with the brake clean
to get out any sludge and let dry. Also clean the bolts at this point
as they are usualy nasty. This is also a good time to paint the oil pan
(outside only!) if you are feeling so inclined.
I personaly dont like to mess with the oil pump or tube removal unless
I have to, but if you are feeling ambitious you can take the time to check
the oil pump, the torque on your crank nuts (sorry I dont have that spec),
and even to check main and rod bearings. If you don't already know what
this all means, make sure you research thoroughly before proceeding.
Once the pan is dry, take the ultra gray and put a fine line going aound
the pan. then place the paper gasket on top of it (please make sure the
holes line up). Next put a thin line of ultra gray on top of the gasket.
You do not need to spreed the ultra gray out as when it meets the block
this will happen naturaly and will fill in the holes better. The ultra
gray keeps the gasket from sliding and fills in any imperfections in the
metal.
Get the bolts ready and load one in the wrench. Lift and hold the pan
with one hand in place and put the bolts in. Drop the engine in reverse
order of how you lifted it, connect everything, change the oil filter
and add the 20W50. Now that everyhting is done go for a test drive to
the store and buy the beverage you were wanting this whole time. Enjoy
an afternoon well spent!
