Good Morning, 1997 Subi Legacy Outback 2.5 Limited. When i start the car ( in any weather ) a loud knock is going on until the engine is warmed up then the knock stays but you can hardly ear it. I thought it was the injectors or at least 1 because it as the same knock sound, but no it's not the injectors. I ear it coming from the back of the engine, maybe from the throttle body area. Any Thoughts ???

Question edited for clarity.
Question moved to model category.

That is pretty crazy. It would be cheaper to get an auto electrician for an hour than to keep buying alternators. If a fuse melts, you have to find the reason why before replacing it. Jimmy rigging electrics just passes the problem along to another component. A Professional Grade Scan tool computer can diagnose in 20 minutes. They cost $3.5k to $5k!

I think you should go for manual first after that it would be easy for you to solve your problem. I had visited this site past 2 months before for my vehicle and find it quite helpful may be you will also get something useful here

You may have the ORDER correct, but the STARTING POINT off by one plug! If you can find the timing mark on the crankshaft, place it in line with the timing indicator, and that should make the rotor (under the distributor cap) point to plug #1. If it looks way off, like 180 degrees away from plug wire #1, rotate the crankshaft one full turn, and recheck where the rotor is pointing! If the knocking problem persists, there may be a problem with the timing belt or chain which drives the distributor at 1/2 the speed of the crankshaft. That would explain the smells because the valves would be open at the wrong times. Caution! Pistons can hit valves that are open at the wrong time! Things can BREAK under those conditions!

I would change it anyway. I would scan it again and see if the knock sensor code is stored.

Check for an exhaust leak at the exhaust manifolds and flanges.

The knock sensor is located on the top of the engine block almost hidden from view by the intake manifold. It is almost directly below the spot where your throttle cable connects. It will have a bolt running right through the middle of it and a single wire coming out of it.

The ignition timing is not adjustable. It is computer controlled by the crank sensor, cam sensor and knock sensor. Would be easier to help you if I knew why you were trying to adjust it. Have a great day.

Sounds like the transmission has reached the end of service life. I have a 93 that did the same thing. It would drive until the transmission heated up then nothing, except for reverse. I had a TRW rebuild transmission installed and now my 93 Legacy has 500,000 miles. $2,200 to repair vs $25,000 to replace. The only thing you would miss is the new car smell for a few weeks. But you can keep $20,000 plus.

Hiya,

Here you go:

2.5L Engine To Remove:

1. Disconnect the battery ground cable.
2. Remove the air cleaner housing.
3. Vehicles with 5-spd transmission: Remove the clutch slave cylinder and set aside.
4. Disconnect the knock sensor wire harness retainer from the coolant hose.
5. Disconnect the knock sensor (KS) wire connector.
6. Remove the mounting bolt and knock sensor from the engine block.

Hope this helps...

Cheers,

knocks when cold ( Start ), then sort of diminish or disappears when warming up ???

Knocking goes faster when accelerating when cold ???

If Yes, then Piston knocking on the wall of the cylinder . The sound disappears as the engine is getting warmer it dilates and the gap gets smaller.

If this just started,

1. Put quality oil & filter ( Mobile Full Synthetic Oil & Mobile Oil Filter or Purolator )

2. Do not put cleaning agents mixed with oil.

3. Personaly i've put "Restore" Engine Restorer & Lubricant in cars with more then 200 000 km and the results are amazing. But only "Restore". My Volvo is at close to 300 000 km, and it runs great. It's not a cleaning agent.

By experience if the knocking just started you can put an easy extra 100 000 km on the engine before a rebuilt. Quality Oil & let the engine warm up ( 3 mins ).
