Is it true that most of the engine wear during its life time occurs during a cold start up?
처리 내용
From advanced-auto-maintenance.com : It’s widely acknowledged by automotive engineers that most engine wear occurs within this first ten minutes of driving before the engine has reached its highest, normal operating temperature. From bloomberg.com : When you first start the vehicle, do not race the engine. Accelerate gradually until the engine (and the rest of the drivetrain) has completely warmed up; it takes about 10-15 minutes, depending on the outside temperature. Most engine wear occurs at cold-start and during the first few minutes of operation. Revving a cold engine will greatly accelerate this wear and tear. Basically, yes. It is true, and basically it's because the oil has settled and is no longer properly lubricating all the parts, creating a greater amount of friction and consequently, wear.

Hello! I have not driven my car for a month and now have this noise. It is a 2016 V Jetta and normally in great shape. The noise is in the background and sounds like something soft is rubbing against something. It picks up at 10 mi/hr or so and then stays on…Thank you! https://global.discourse-cdn.com/cartalk/original/3X/3/f/3f6ae6628ea80cf8d6b1899d0b2392d868545516.mp3

Power seat - Whenever vehicle is started or shut off and the seat slides forward of back, the power seat makes an annoying, obnoxious noise… I thought something was stuck in the track but now I think it’s the motor going out. Guy at the local dealership said it just needed grease. He appears to be incorrect. Any thoughts? Thoughts?

A buddy and I were trying to replace his right front wheel hub, on his 2008 Chevy Impala LTZ. He described the engine size as 3900, I would think that means 3.9 liter, although I didn’t know there is a 3.9, I only know of the 3.8 liter and 3,1 Liter. One of the mounting bolts is so tight that the socket would not keep a grip on the bolt head, no matter how hard we tried to force the socket onto the bolt head. We had tapped on it as best we could with a hammer and metal rod, we heated the area with a torch, no luck. Of course, very little access to this bolt head, so impossible to use an impact
