2003 Subaru Outback H6-3.0 Bend Valves?

Post by sbebenelli »

We have a 2003 Subaru Outback H6-3.0 VIN 4S3BH806237606903 that has something wrong with the right timing chain. We have not pulled the cover to see what happened. Does anyone know if these bend valves when the chain breaks?

We do not see many Subaru's around here.

I know a 4 cylinder would, not 100% sure on V6. I assume they will. Let me make a call

Wholesale parts guy at Subaru doesn't think it bends valves.

Cover Area


SOURCE: Subaru Tech Tips

TITLE: Engine Noise - All H6 Vehicles

APPLIES TO: All 6 cylinder vehicles except SVX

SERVICE TIP:

If you encounter an H6 engine with a noise coming from the front timing chain area and suspect it might be caused by the timing chain tensioner, please follow the instructions below. SOA has tried this procedure and found it to be an effective fix.

Repair Procedure:

1) Start the Engine
2) Raise engine RPM's under cold condition, up to 5000rpm 3 to 4 times.
3) Confirm whether the noise is eliminated.
4) If the noise still exists, repeat above procedure again.


If you cannot eliminate the noise with above procedure, replace Chain Tensioner.

Forcing the tensioner like this isn't a proper repair as far as I can see. Improper oil, restricted port to tensioner feed, bad tensioner, bad guides or stretched chain comes to mind.
