Subject: Changed to 5W-30 oil, but...

   Date: Fri, 1 Nov 1996 23:13:07 -0500



Today I changed my oil to 5w-30 to get rid of the lifter noise that I've

been getting when starting the engine cold. It was my first experience

changing the oil in the Miata ... had a hell of a time getting to that

filter. :) FYI, I used Castrol GTX 5W-30 oil, and a Mazda oil filter.



Anyways, now that I've changed the oil, I'm getting a new noise. When

listening closely to the engine, I hear a random knocking noise. Its pretty

faint, and has kind of a deep sound to it. It can be heard especially well

with the hood open. However, you can't hear it from inside the car at all.

The noise is constant, you hear a knock pretty much every second even though

it is totally random. I should also mention that I filled the tank with some

new gas at the same time, but I don't suspect this is the problem as the gas

was from the same place I always get my gas.



Any ideas what this might be?



Thanks!

Ryan
