回複：thanks a lot! unfortunely I did that for many times.

I only replaced timing and blance shaft belts on my 96 Accord at 75k miles.  My guess is that valve job requires engine head to be disassembled and reassembled.  If the pistons are dented, you may have to replace pistons, that requires whole engine out off engine bay, a huge DIY job.

• Replacing pistons is very easy once you removed the engine head. -buddy1234567us- ♂ (378 bytes) () 12/30/2010 postreply 21:06:02
