Clack Clack Clack!

[Zoobaru]

I thought I`d ask right off, what is the cause and remedy for the inherent clacking in many of the older Subaru engines? My roomate has a GL that has a bad case, and it's getting to the point it either needs fixed, or it needs a louder stereo.

Its a metallic tick... right? Get a screwdriver, stick it on your engine and hold the plastic to your ear to track it down. It may be piston slap or something real bad... but hopefully its the tick of death.

You could get tied up for days reading all the questions and answers about ticking/clacking/knocking.

 

What folks here cal TOD is lifter noise. Hope thats what you got. If not, could be anything from rod knock, crank walk, to piston slap or even mains.

 

I say if it goes away when it's warmed up, ride it till it dies. And if every week it's getting a little louder, start preparing for a new engine or a major rebuild.

 

Good luck and have fun!

Well then, I guess that proves that yours was TOD. Oil pumps don't fix bearing, crank, or piston skirt noise. (I have been told that piston slap is nearly no-existant in these engines)

 

Maybe a good question is how to tell the difference. One way has already been mentioned, listen with a screwdriver or mechanics stethascope to track it down.

 

I'd just hate to see somebody spend the dough on a new oil pump trying address a bearing problem.
