Help,

I have a 96 V6 Accord with an intermittent valve tap, it seems to fade in and out once the engine warms up. My mechanic has recommended an engine flush over a valve adjustment since it seems to be in only one of the overhead valve. I'm very lery on engine flushes since this engine has over 250k miles on it. I've tried Seaform to no avail, any suggest, comments?
Thx

Like alko said, valve adjustment. An engine flush isn't going to make any difference if there is a little too much clearance between the rocker and valve (parts do wear). When was the last time one was done? Without pulling out my service manual, I think the Honda recommended interval is probably every 30K or 60K miles.

 

Pretty sure its 30k
TO OP: i would say the same valve adjustment 1st.
