    Do I really need a Fuel Pressure Gauge?

    I believe there's value in having tools and test equipment on-hand, especially if they're inexpensive. So I'm thinking about getting a Fuel Pressure Gauge set, but not sure what scenarios it would actually be useful for. If the fuel pressure sensor on my fuel rail is faulty (happened twice so...

    Brake Hose fitting comparison (interesting)

    I recently purchased several Sunsong brake hoses from RA. One pair with the same part # consisted of hoses maded in two different countries, Thailand and China. They are very similar, but one difference is the bolt on the fitting for the caliper. As shown in the photo, the bolt is solid on one...

    OEM Timing Belts - do they really break?

    Is anyone aware of any genuine OEM Toyota timing belt that ever failed, whether it was the result of high mileage or old age? I have heard stories of aftermarket timing belts that broke, but not OEM. Of course, I don't know everything that's going on out there, so that's why I'm asking.

    Door Weatherstripping loosing grip

    The rubber weatherstripping around the edges of the rear door on my 2002 Mazda Tribute (a rebranded Ford Escape) is falling off the body where it normally slips on. The seal is broken causing a lot of wind noise while driving. I can push the weatherstripping back on ... it holds for a few...

    Fully Coated Brake Rotors and Ceramic Pads

    I'm seeing more brake rotors advertised as partially-coated or semi-coated where the coating is limited to the non-friction surfaces of the rotor. The friction area of the rotor where the pad makes contact is not coated (or is very lightly coated) enabling new pads to bed a little faster. I'm...

    Floor Jack - safe to use at an angle?

    I have very limited floor space on either side of my parking spot, so I cannot position the floor jack perpendicular to the side of the car. However, I can fit it under the pinch weld at an angle. And there is room for the jack to move on its wheels as the arm is raised. For the handle, I may...

    CV boot diagnosis on jackstand

    2008 Land Rover LR2. All original OEM CV axles. 168K miles. When I recently had new tires put on, they told me there was a small leak near the large clamp on the outer boot of the front left CV axle. Now it's spewing grease which is very thin in consistency, almost like oil. No clicking noises...

    M1 Flash Point - how do they do it?

    For their 5W-30 Advanced Full Synth HM engine oil, Mobil 1 publishes a flash point of 245C/473F on the product specs. This is significantly higher than other Group 3 oils, and even higher than some Group 4/5 oils. What are they adding to achieve this impressive flash point? Could whatever they...

    M1 Advanced Full Synth HM 5W30 and M1 Extended Performance Full Synth 5W30

    Attached are VOA's for these two M1 oils. I also included docs from the M1 website showing specs for each respective oil. As of the date of this posting, Walmart is selling a 5qt jug of the Adv for $22.37, and a jug of the EP for only two dollars more at $24.37.

    Check the runout on new brake rotors?

    I watched a video demonstrating how to check the runout with a dial meter. Unexpectedly, the runout was measured out of range for a brand new replacement rotor! It wasn't a problem with the hub surface the rotor mates to, but the rotor itself. They returned it as defective. I suspect that most...

    Air in ABS Brake System - impact on normal braking?

    Some drivers report a soft brake pedal and suspect the cause is air in their ABS (after they've done a standard bleed on all calipers). For most ABS systems, I understand the ABS remains in a passive/off mode during normal driving and only activates when it senses an extreme imbalance in wheel...

    Automated ABS brake system bleed

    I'd like to confirm my understanding of the bleed process when you have a scanner that supports ABS Automated Bleed. Step 1: Bleed the brakes in the standard manner (whichever method you choose). Step 2: Use the ABS Automated Bleed feature in your scanner to cycle the ABS. The pump action will...

    Brake Fluid testing - moisture & copper

    Typically, testing for brake fluid contamination is done at the master cylinder reservoir for obvious reasons. For moisture, it's probably the best place since air bubbles rise and the reservoir is located at the high point of the brake system. So you're getting a sample of the worst moisture...

    Brake Fluid contamination from Penetrating Oil on bleeder screw?

    Advance preparation for brake bleeding often includes the application of penetrating oil of some type (e.g., Kroil, PB) around the bleeder screw to assist in removal. In some cases, it's applied daily for several days in advance of the bleed operation to allow it to soak in and do its thing...
