Honda cam seal replacement

Last Updated on July 23, 2024 by Mutiara

So this write-up is going to be done on a B18b1 motor, but its basically the same on all Honda 4cylinder motors. This is a very easy replacement.

Things you will need:

Procedure

To start off, make sure your motor is cool. You dont want to burn yourself here. Start off by removing the spark plug boots and wires. Remove the vacuum hose if you have one, I use a breather filter instead. Remove the valve cover bolts and pull it off.
Locate your cam seal, in my case it is the left side on the front camshaft. It is the black circle.
Remove the four 10mm bolts holding the camshaft cover and cam seal cover in place. The cover may be stuck on there pretty good, so use a small flat head screwdriver to gently break the seal.
Remove the old worn out cam seal, and place in the new one. I am using the Skunk2 cam seal. It is much better than the stock, having 3 thicker O rings for a better seal. Put a small amount of Hondabond or other gasket sealer around the new cam seal and place it in its spot.
Put a small amount of sealant on the outer edge of the cam seal cover and place it back on.
Torque the four bolts back down to 7.2 ft lbs.
Place the valve cover back on. Torque the bolts back down in the correct order for your specific motor. Put the spark plug boots and wires back in place. Put the vacuum hose back in place if you have one, take the vehicle through a driving test to make sure the oil leak does not reoccur.
