On the weekend i replaced the spark plugs, they were fine for about 20k's of driving, i then decided to rev the car out to 8,000rpm and ever since then my car is running as though one of the pistons arent firing 100%
Some may know of the "wrx" noise a honda motor will make if a piston is dropped, mine is making a very slight "wrx" noise, i thought it was just me being paranoid at first but it definately has a slight noise of a faulty piston, also there is more smoke than usual coming out of the rocker cover and the pcv valve.
The replica mugen rocker cover i have on had loose paint around the spark plug holes, this paint is almost like rubber.
I personally think some of that paint has dropped into the hole when the plug was out which is getting in the way of the spark, which would explain it not firing 100% as well as the extra smoke coming out.
Im planning on removing the whole head this week to get to the top of the piston to find this paint. The thing that i would like to know is does anyone recommend anything before i pull the whole head off for absolutely no reason?? Is there a way of cleaning the pistons without stripping everything apart??
