Corrections & Notes to the
(Red and white cover)
- Page 43: A reader
suggested the following addition to the section on removing the
valves from the head:
Before pushing the valve stem through the
guide to remove it from the head
inspect the upper section of the valve above the recesses where
sit to insure there are no burrs on the valve stem otherwise the
burr can damage
the inner diameter of the valve guide. Whether your valve guides
are relatively new
or worn this will make slipping things out easier."
190, Figure 10-16. This figure may not be
perfectly clear to those with 911SC and Turbo engines. This
is a photo of a 2.7 distributor installed in the engine.
When installing plug wires on your distributor, be sure that the
wire for plug #1 always lines up with the notch on the inside rim
of the distributor (shown in Figure 9-13). The location of
the clip that attaches the cap to the distributor has varied over
the years, so don't use that as a guide for installation - always
use the mark on the rim of the distributor.
168, 1st paragraph, last sentence: "you would turn the
crankshaft until the value on..." It should say "camshaft".
134, 2nd paragraph: "Install them in the case so that the
nuts are located on the left side of the engine." It should
say "right side of the engine", similar to how they are shown in
Photo 3-28 (the photo is correct).
200, Page 139/140: There seems to be an issue with
people using the wrong type of bolt for the air conditioning
pulley. This bolt should be a 12.9 specification bolt.
If it's not, then the bolt will probably snap when you tighten it
up to the proper torque. There's a
good thread on this in our forums.
155: The text is confusing in the 2nd paragraph in
the left hand column. The text says "If you look at this
camshaft down its axis," when it should actually read "If you look
at the left-hand camshaft down its axis"
73, Photo 4-11: There is a
white dot in the photo without a number. This points to
valve stem seals and assorted extra o-rings. The valve stem
seals are typically installed by your machine shop when you have
your heads rebulit.
- Page 84, Photo 4-14: The photo shows a replacement steel stud from Porsche. The steel studs installed in the cases often do not have black paint on them, and look just like the Dilavar studs. Use a magnet to determine which ones you have.
- Page 105, first line of text on the page should read "moving the rotor closer to the firing point on the distributor"
Bearing Sizes - Rod Bearings (D2). The numbers listed for
the 2.0/2.2 and the 2.4/2.7/3.0 are incorrect. They should
911 Turbo (1976-77)
Euro Carrera (1976-77)
Arm Bushings, (901.105.043.98).
Porsche doesn't appear to be carrying this part anymore. I'm
currently looking for an aftermarket bushing to be used in place
item number 21, should be listed as 911 (1978-89)
- Page 185 -
In the caption for Figure 10-6, the swivel
foot is shown on the left, not the right.
120 - Plastigage
should be used at the sides of the rods - not in the middle. The
rods stretch when under load, and you want to measure the
clearances at the side.
- Page 160
- Figure 6-11 shows a mirror image of what it should be (chains
should point in opposite directions)
- Page 169
- Figure 7-14 is slightly misleading. The 0.1mm indicator in
the left of the figure represents the valve clearances while
setting the cam timing.
- Page 210
- The very first
column at the top of the page says "2.2" when it should say "2.0"
Corrections in the First
(all Red Cover with yellow lettering
in the title)
there are 11
total through-bolts that need to be removed, not 10 as stated in
the last sentence of the first paragraph.
the rod bolt
torque value lists the Porsche spec for the later-style rod bolts
(911 1984-89 and Turbo 1978-89). There is a note at the
bottom of the page regarding the change in the spec. Some
people prefer to use the earlier spec of 50 Nm (36.2 ft-lbs),
documented at the bottom of the page.
1973 1/2 911T,
engine types 911/91 and 911/96 are listed as having a bore of 90mm
instead of the actual value of 84mm.
the final torque
value for the 1978-89 911 flywheel bolts is incorrectly listed.
The actual value should be 90 Nm (66.3 ft-lbs) as is listed in
- Page 208: the notation under the cylinder
diagram says "cylinder CT." This is a layout marker and has nothing to do
with the actual diagram
- Page 208, on the same diagram:
- A = tolerance group for cylinder height
- B = tolerance group for cylinder diameter
- C = Manufacturer's Identification
- Page 154 - The cam
nuts should be torqued to 75% of the value listed in Appendix A.
- Page 159 - The value
54.8mm should be subtracted, not added to the value.
Also, the shim thickness is 0.50mm, not 0.25mm
- Page 199 - It should be
915 transmission, not 914 transmission.
- Page 77 - The four
vertical lines are indicated by the green arrow, not the blue
- Page 216 - The intake and
exhaust valves are numbered incorrectly in the photo (1 = Intake,
2 = Exhaust)
- Page 204 - The 911SC Rod
Bearing Journals should be 53.020-53.059 for the bore, and
52.971-52.990 for the shaft
- Page 204 - The 3.2/3.3
Rod Bearings Bore should be 55.020-55.059
- Page 77 - The Turbo pump
has a larger pressure side as well as a larger scavenge side.
- Page 16 - "...when the
cylinder heads have broken..." should read "...when the cylinder
head studs have broken..."
- Page 112 - 44 Weber Carb
should read 40 Weber Carb
- Page 112 - Typo
- Page 183 - Section
Heading should be "REAR ENGINE MOUNT BAR" or simply "ENGINE MOUNT
- Page 197 - "...you let
the clutch out..." should be "...you let the clutch pedal out..."
- Page 119/120 - "Plastigage"
- Page 82 - Glass plate
method is described in Chapter 5, Section 9
- Page 180 - Valve Covers,
13mm hardware should be 8mm hardware
- Page 153
- Figure 5-9 shows an area that is larger than needs to be covered
with the sealant. The flat surfaces of the heads shown
in the figure directly above it are what need to be sealed.
In reality, the horizontal bars on the cam towers (on the ends and
in-between the cylinders) do not need to be coated. If you
follow the diagram, you will use more sealant than you need to -
possibly creating a messy situation.
- Page 73
- Valve cover gaskets should be listed as 25/26 in Figure 4-1.
