The short answer is: none. A grade eight bolt that's broken off in the engine is almost certainly not going to extract in any conventional fashion. There's just too much torque on the threads. If you're going to drill a pilot hole big enough to get a grip on the remainder of the bolt, you're basically going to have to drill with a huge bit. Instead, the ...

Simple answer that all the forums seem to agree on, and that my garage also approves is that you will get better airflow to the manifold, however unless you also adjust your ECU, and potentially replace your Mass Airflow Sensor (depending on exactly what you are changing in the airflow path) then you may have problems. I had the full Prodrive Performance ...

There's an excellent Subaru parts catalog online. I think this is the drawing you want. I'm not sure what you mean by "front" bolt, though -- isn't one directly above the other?

From past experience, I've found that headerwrap (a company called Thermotec makes some nice stuff) is a lightweight alternative to replace heat shields.. HOWEVER..I've found that the wrap traps moisture. I had used this stuff on a set of headers and within 2 years (this is in the west coast mind you - no salt or snow), i had 2 primaries rust and ...

It sounds like a failing throwout bearing. When the clutch pedal is depressed the part that actually moves the fingers or diaphragm of the clutch is the throwout bearing. While the clutch is disengaged the flywheel and pressure plate assembly are still spinning at engine speed. With the clutch the face of the bearing spins while the backside is stationary ...

Check the seals where the axle-back attaches to the stock exhaust, you may have leak which can change the pressure and thus the sound.

This concept works surprisingly well on some engines. As you have mentioned, the issue is whether the dipstick tube allows full access to the sump. It's unclear from this diagram whether the tube would reach down into the sump. It's also unclear if the tube would run into a baffle or the pickup tube instead of going all the way to the bottom of the sump. To ...

I have one of these. Inserting the suction hose into the dipstick tube didn't allow me to remove even half of the oil (the container is marked to show the level of the contents, though it's hard to read except in bright sunlight). However, there is an easy solution! Measure the dipstick tube diameter and go to your parts shop for a suction hose with a ...

A trip to the dealer had the car up on a lift with a puzzled mechanic wandering around underneath, repeatedly causing the rattle to trigger. After a while, we both looked under the car and have concluded that the problem is the heatshield over the right hand exhaust manifold. That isn't terribly surprising: heatshield metal has never been good and, after ...

I just realized that I never followed up on this question: It turns out that the rattle was coming from the connectors holding down the large trim piece that lines the base of the windshield. It's a long piece of curved plastic with vents for the defroster and happens to have the VIN tag attached to it. If you pull this piece (using a wrapped screwdriver ...

The vin tag can get loose sometimes. It should be up by your windshield on the left side. They are intentionally not made easy to access. Which begs to question why they would also frequently become loose on old cars but I digress. Because of how hard it is to access I would suggest using some clear RTV on each end to stop it from rattling. The added bonus ...

Best source is your local dealer. Depending on how good the parts diagrams are, it can be a pain ordering the correct bolt. If you do it online or over the phone, there's a good chance they'll order the wrong one. Go to the parts counter and look at the picture with the parts specialist.. hopefully the exact bolt is easy enough to point out. Chances are, ...
