Have a 00 lx with 250,000 km on it. About 3 weeks ago, the engine started ticking. Noise seems to come from the front right of the top of the motor. When first started, there is no noise at all. After about 30 seconds, you hear a knock or two here and there and then after about 1 minute it's steady and loud.
As you rev the engine, the knock gets faster. Engine still runs fine, lots of power, but the knock is driving me nuts. Still sounds as loud when the engine fully warms up too. The strange thing is, I figured out that if you disconnect the front right injector plug... the noise is gone.
I've replaced the injector, but there is no change. If it was a bad or sticking valve, or water pump, tensioners, etc...removing the power to the injector shouldn't have any effect right? I'm just trying to figure out what this could be before it goes into the shop....or up for sale.
I'm starting to think it's a nasty piston slap or worse like bolts coming loose on the rod. This problem also didn't occur slowly over months. One day it was fine...the next..knock city.
Any suggestions or help would be appreciated.
