18. Remove the smog pump components. There are solenoids
and tubing on both sides of the engine. Take a few snapshots so
you can remember where things go and how they are routed.
21. The windage tray and oil pickup tube. Remove both of these
and set them aside. Note: If you intend to reuse this case or have
to split it, there is a 10mm stud underneath the tray that will need
to be removed.
24. Unbolt the cam cradles and remove the cams. Note: The
cradles and cam caps are line-bored and must be put back in the
same place you removed them from; otherwise they will not line up
with the cams properly and will either fail or eat into your cams.
27. “CC’ing” your heads. To make sure that your pistons and
heads will combine to make the proper compression ratio, you
must determine the volume of your heads. Go to www.subiesport.
com for an instructional video on how to CC your heads.

19. Remove the bung for the oil cooler (you will need it again)
and unscrew the oil pan.
22. Unbolt the valve covers and set them aside.
25. Un-torque the cylinder heads: This is done in reverse order
of the torque sequence: Start in the top right corner, then go to
the bottom left, bottom right, top left, bottom middle, and then
top middle. Do this in two stages: Relieve the torque about half
way first, then completely in the same sequence. Note: The cam
buckets must be kept in order. If these are rearranged at all, your
cams will be out of adjustment, don’t mix these up. Marking
them with a sharpie is a good idea since they will have to come
out.
28. The parts washer. All parts that are to be reused must be
washed. The first step is to run them through a solvent tank. If
you don’t have one, a basin and a good solvent with a plastic
brush will do.
20. Remove the oil pan. This can take some doing as it is bonded
to the engine with Fuji Bond. A paint scraper and a hammer will
help separate the pan from the engine; just don’t ding the block.
23. This is what the inside of your engine looks like if you don’t
change your oil frequently or use inferior -grade oil. Project LGT
made two trips back-and-forth, Seattle to Las vegas, in the span
of 4 weeks without an oil change.
26. Light scoring on the top of this cylinder wall is a good indicator
of a cracked ring land.
29. Clean vs. Dirty. You want to make sure that your new
engine is as free of old oil and contaminants as possible. When
you are done with the solvent tank, spray everything out with
brake cleaner to get rid of the solvent, then blast all parts with
compressed air to make sure nothing is left behind. Solvents
and cleaners can dissolve oil inside the engine and that would
be bad.
