ok, so i changed my oil about 4 weeks ago. i started to hear some tapping from the top end and assumed it was a lifter…. nope, 2 quarts low!!!! WTF! no leaks, no noticeable smoking… the hell?
i changed the plugs, this is what i found…
the nasty one came from cylinder 3. the white specs could be caused by knock, the rest of the plugs looked great. i replaced the plugs with Densos.
a week later i pulled the plugs to check them out, look at cylinder 3 again…
i did a compression check, 180psi across all 4.
the sutty plugs could be a faulty injector, (none of the plugs were oily)
i pulled all four injectors and cleaned them. i put injector 3 in #1 spot to see if the problem follows the injector.
while i have my injectors off, i figured id check the manifold for oil… this is what i found:
and touching the TB blade i get this…
my car is 100% stock minus a cone filter that i installed tonight. i had just replaced the PCV valve with the Densos. all emissions are intact (i assume thats where the sutty black came from the manifold)
i really need to figure out if the plug and the oil are one in the same. i can't have an oil leak/burn killing my octane rating and causing knock when i go FI.
