blocks and turn key engines are assembled from all new parts. Partial
engine break in has been accomplished by running the engine on the
dyno prior to shipment. However, it’s advised to drive the engine
conservatively for the first 1000 miles while keeping the RPM under
5500. Use premium fuel. Do not over rev a cold engine. Allow the engine
time to warm to running temperature before exceeding 2500 RPM. Blipping
the throttle on a cold engine can damage the rings, and bearings.
in new engines should be adjusted at the first 100 miles and thereafter
at every 2000 miles. High performance VW engines are equipped with
solid lifters and Chromoly push rods. The valves should be set at
.002 lash with the engine cold.
covers must be removed prior to adjusting the valves. A basic valve
adjusting procedure to follow is to set # 1 cylinder at TDC * and
check the lash setting on the intake and exhaust valves on # 1 cylinder.
.002 lash can be attained by loosening the adjusting screw lock nut
on the exhaust valve, and turning the adjusting screw inward (clockwise)
until the swivel foot fits firmly to the valve tip. Turn the adjusting
screw out (counterclockwise) until you can rotate the push rod with
your thumb and fore finger.
the adjusting screw nut, check the push rod to make certain that it
rotates. The adjustment should be firm, no extra end play, and allow
the push rod to be rotated. Repeat the adjusting sequence on the intake
valve. Re-check both valves on the # 1 cylinder. Make certain the
there is no extra end play and that the push rods can be rotated.
the valve adjusting operation on # 2 cylinder, but first rotate the
crankshaft 180 degrees to the left. A ½ (180 degree) crank
rotation to the left will position the # 2 cylinder at TDC.
the valves are adjusted on # 2 cylinder, rotate the crankshaft another
½ turn to the left and adjust the valves on # 3 cylinder.
# 4 cylinder is reached by rotating the crank another 180 degrees.
The valve adjustment procedures are the same on each barrel. Replace
the valve covers when all of the valves are adjusted.
lash becomes a safe margin as the engine warms. The increased temperature
causes the barrels to grow more than the push rods and additional
clearance is created in the valve train.
valves should be adjusted at every 2000 miles.
center (TDC) can be located by rotating the crank to position the
timing pulley at TDC. This will indicate that either number # 1 or
# 3 piston is at top dead center. Remove the distributor cap and check
the rotor to determine which spark plug terminal the rotor is pointing
at. If the pulley is indicating TDC and the rotor is pointing to #
1 terminal in the distributor cap, # 1 cylinder is TDC. If the rotor
is pointing to the number 3 terminal in the distributor cap, # 3 piston
is TDC. TDC on # 1 cylinder can then be reached by rotating the crankshaft
1 full rotation to the left.
or TDC cylinder can also be determined by rocking the crankshaft back
and forth in a quarter rotation. Valves will move on every cylinder,
except the one that is TDC.
oil should be changed at every 2000 miles. We recommend the use of
Kendal GT1 40 wt. or Kendal GTI 20 – 50. The oil pick up screen
located in the bottom of the engine should be removed and cleaned
as part of every oil change. Make certain to re-fill the engine with
oil prior to re-starting. Engines without accessory oil sumps require
slightly less than 3 quarts of oil. CB engines are often equipped
with accessory oil sumps that are available in 1 quart and 2 quart
engine will require additional oil if it’s equipped with an
accessory oil sump. Engines equipped with external oil coolers and
filters will also require additional oil. The amount of additional
oil is determined by the volume of oil in the external cooling and
procedures (after oil change)
the crankcase to the full line on the dip stick. Disconnect the coil
wire, crank the engine with the starter until the oil warning light
goes out. Re-check the oil level, and if it’s at a safe level
on the stick, connect the coil wire and start the engine. Observe
the oil light, and gauge, make certain that the engine has oil pressure,
and let it idle for about 1 minute. Turn the engine off and check
the oil level, add oil if required. Repeat the oil check and look
for any signs of oil leakage. Do not operate the engine without sufficient
timing should be set at 30 degrees BTDC at 3000 RPM. This is accomplished
with a strobe light. The exact ignition timing at idle speed can vary.
What is important is not to exceed 30 degrees BTDC at 3000 RPM. Idle
speed RPM should be in the 900 – 1000 RPM range.
plugs recommended for use in 044 cylinder heads are NGK DP8EA-9.
