I changed all the seals in the spark plug cavities on my Honda Accord because they were filling up with oil and when I put it all back together and stated it there was a loud steady ticking noise.Still runs good and there seems to be no loss of power when driving the oil level was also good.
Richard, On your 1991 Honda Accord, Make sure the sparks plug are tight and torqued to specs. Make sure the ignition wires have good connection. Check the valve cover gasket. That is a common problem and can cause oil to fill up in the spark plug cavity. Good luck.
