Adjustment of headlights...how to

Check compression...on all cylinders

Look for a poor ground on the LH light assembly. You'll need to remove the assembly to do this.

The service manual calls for 5W-30. Full synthetic would be your best bet on oil changes with a OEM Subaru oil filter and new gaskets (o-rings). Depending on your area (hot or cold), the viscosity rating of the oil you use can vary to off set efficiency in the hot or cold temperatures.

have you checked your fuses under the hood

sounds like it is air bound look for a bleeder

there are individual fuses for each side headlamps,both are 15amp located in fuse box underhood,check em out

Are you absolutely positive you are installing the correct amp fuse ?
I think headlights on Subaru's run thru a relay, which could be bad.
Here's a how-to that may help.


Headlights Not Working Try These Fixes

i read about a recall on some subaru headlights/check with subi dealers?

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.

I have a similar problem, engine management shows code P0327, knock sensor 1 dont know what that is.
