Originally, this article specified an STR cam
seal. STR is no longer in business, but there are numerous
sources for an aluminum cam seal for your B-Series engine.
Summit Racing and JDM Password are a few examples of sournces for
this seal.
A simple problem, common to most B-block Honda
engines is to have an oil leak around the front cam seal. A
simple and aesthetically pleasing solution is to replace the seal
with an aftermarket aluminum seal. These cam seals are a machined aluminum piece which utilizes
multiple rubber o-rings to create a seal. The seal comes in a few
different colors. I chose the red anodized seal.
Tools Necessary:
- reliable socket set
- metric wrenches
- high temp sealant or Hondabond
The installation process is very easy. Start by
removing the spark plug wire cover. Once that's out of the way,
pull the plug wires out and lay them over to the side. Remove the
valve cover and set it aside.
Once you have the valve cover removed, remove the
rail across the cam caps.
Then, there are a couple more bolts that need to be removed to
get the cam cap off. Once you get those off, carefully pry the cam
cap off.
Once that's off, remove the plastic oil seal and pitch it. The
instructions for the seal recommend that you lightly coat the o-rings
with oil and apply some sealant to the back of the seal. I just
lightly applied some sealant to the inside edge. When you put the
seal back in, it's a tight fit so don't be alarmed. Reinstall
the cam cap and torque down the bolts to about 7 ft-lbs. With
the cap in place, reinstall the rail back on and torque those bolts down to
20ft-lbs. of torque. Reinstall the valve cover, sparkplug wires and
spark plug cover.
