Would you consider the camshaft oil seal to be an internal engine part?

I am sure some would say it is and others would say it isn’t. The others would be the warranty company looking to avoid paying.

One could argue that the oil seal can be changed without the need for opening up the engine. However the timing belt has to be removed along with the back cover. So if the timing belt is considered an internal engine component then the camshaft seal would also have to be considered internal.

My opinion is the camshaft oil seal is an internal engine component. I am basing this opinion on the replacement procedure of the oil seal itself according to the auto repair manual procedure. The new camshaft oil seal is to be installed first and then the camshaft into it. This means the camshaft needs to be removed before hand. And there is no denying the camshaft is internal. I will ad the auto repair manual procedure so you can get a better idea of what I am talking about.

Buick Century

What would make my car stall all of a sudden while I’m driving at 40mph. And now it will not start or even crank the engine over. It has gas, lights come on. Please if you can point me in the right direction.

Will not start but lights come on

Quick answer would be the BATTERY and or Alternator.

If the alternator quits working the engines computer and engine runs completely off the battery. This could be from a failed alternator, alternator connections or a broken serpentine belt. The engine continues to run off the battery until the voltage drops below the computers threshold then causes the engine to die. At this point the battery is too weak to crank over the engine.Generally if this is the case the BATTERY light comes on.

The battery does still have enough juice left to operate the lights and radio. The lights draw about 15 amps, the radio draws about 5 amps to function. The starter draws up to 250 amps to operate.

2010 Pontiac G6

I put a new (used) motor in my 2010 Pontiac G6. And when you turn the car on the backup lights come on and stay on.All the lights on the dash work. But when you go to start it nothing happens. It won’t click it, won’t do anything. I figured it’s something to do with the security system but the security light goes off as soon as you turn the key on so I’m stuck.

We have developed a Flow Chart for diagnosing no start situations. Take a look. I will ad a wiring diagram of the starting system to help assist with this issue. Check your battery connections, then your starter fuse #26.

1998 Toyota Corona

Jerks backward uncontrollably

My 1998 Corona Exiv rolls for a bit when in reverse, then stops suddenly even though the accelerator is still depressed. It eventually jerks backward uncontrollably for a few meters. Then responds to the brake pedal being depressed. This problem doesn’t occur when the car is in Drive.

This sounds to me like a transmission related issue. The first thing to check would be the transmission fluid level.

If the fluid level is low, top it off and retest several times. While checking the fluid if the color appears dark or burnt looking it may be too late. Burnt color fluid is an indication of worn internal material.

Chevy Silverado

My battery went dead. I replaced it. Now I have no power windows, locks, lights, etc. and it wont start.

No power windows

My guess would be you didn’t get it connected right, have corrosion at the battery/cables or you managed to blow a fuse or two. The starter has a relay a two fuses to check. Fuse 60 and 64 should be checked. The windows do not have a fuse, this is what leads me to think it is a bad connection at the battery. Not to mention it was the last thing that was worked on. Double check your work.
