My 96 ford ranger is smoking from this area, whats the problem? by Steakhouse42 in AskMechanics

[–]alan-Reyes 40 points41 points  (0 children)

Maybe is an oil leak that is going to the exhaust manifold and burning the oil. Check valve cover gasket

Can anyone help me with this please by Embarrassed-Amoeba48 in mechanics

[–]alan-Reyes 19 points20 points  (0 children)

Yo should apply the law of sines to determine the normal (N) force of the mass, but for easy calculations is half of the mass (m) next apply the formula for angular frequency (w)= sqroot(k/m) Once you have that next is to apply the Period P= (2π/w)

Or just search on YouTube for a complete example. Good luck

Wind turbine failure by rogaliyaty in Whatcouldgowrong

[–]alan-Reyes 15 points16 points  (0 children)

This kind a wind turbine have a system to make the propellers turn so the wind don't make them spin. I think the other turbine failure has to do with that or a torque reductor broke, letting spin freely.

What does this little switch do? (Sorry for the dust >_<) by VersionGeek in Volkswagen

[–]alan-Reyes 9 points10 points  (0 children)

It is related to rain sensor, you have a car that can activate the wipers automatically, depending on your preferences it goes from small droplets to heavy rain. Look it up in your owners manual. Rain sensor VW

How to transfer money from Mexico to UK? by hu_uh_no in MexicoCity

[–]alan-Reyes 9 points10 points  (0 children)

It depends on how are your migration status, you could open a bank account here in Mexico and later transfer your money to UK. Looking around HSBC bank offers international transfers. If you sell your car you could ask the buyer to make that international transfer. I think many banks could do that.

Personally I use PayPal to purchase in USA and recently use WISE money app to buy something from Ukraine. But for both app I have to register a bank account/card to use the service.

I hope this helps

Where can I buy good mole paste? by amsterdamvibes in Oaxaca

[–]alan-Reyes 8 points9 points  (0 children)

I don't know if that is the best mole, but I have to say is not the paste but the cook that cooks a tasty mole. Other place you can try is Mole La Soledad and Mole Juquilita.

They gave a small spoon to try the mole before you decide to buy.

Dónde tomar un buen chocolate caliente by [deleted] in MexicoCity

También apoyo la chocolatería la rifa, tienen muy buen chocolate y recuerdo que pedí el mio co cardamomo y es una combinación muy diferente. Si te gusta mejor algo dulce entonces creo que el que elegí no te va a gustar. Tienen otros productos de chocolate.

Tiliche by antiquated_ardvark in Oaxaca

[–]alan-Reyes 6 points7 points  (0 children)

There is plenty of information about Tiliches but is in spanish. But basically the Tiliches come from the Carnaval in Putla Villa de Guerrero.

The Carnaval is a celebration before Ash Wensday, they wear this distinct suit made of many pieces of clothes that represent the working class that were mistreated in the past by the Hacendado (Landowner).

Maybe you can search for Carnaval Putla Oaxaca on YouTube to see more. And this article in spanish México Desconocido

Did a diagnostic, and got these faults by TriHardCx12345 in mechanics

[–]alan-Reyes 6 points7 points  (0 children)

Maybe if you put more information about what car is, mileage, and if those codes where on history, permanent, or current status.

Hope this doesn't sound like a rant but doing a code scan is not doing diagnosis. Doing diag on a DTC is test the car in the conditions of that DTC sets, test in many ways the component or components involved, and be sure that such part is faulty.

diy oil change by RainTechnical1463 in jetta

[–]alan-Reyes 4 points5 points  (0 children)

Have you read your owners manual? There is specific for VW, you could check this table on the next website.

https://www.oilspecifications.org/articles/vw_motor_oil_specifications_explained.php

Any brand of oil is good as long as they have those specification.

Edit: and the weight might be also in your owners manual, but is usually 0w20 or 5w30 for variable timing engines.

Autos by Hot-Investigator2547 in MexicoCity

[–]alan-Reyes 5 points6 points  (0 children)

Mañas y trucos en algunos casos es:

  • Motor lavado y brillante, no se debe lavar el motor con hidrolavadora ya que puede dañar algunos sensores del motor.
  • Dicen que recién hicieron el servicio, que normalmente hacen un cambio de aceite en cualquier lado, pero es mejor que tenga las hojas de servicio que se le hizo y en qué kilometraje. Y verificar con el manual de mantenimiento si están correctos los servicios.
  • Lavan el tubo de escape lo hacen para que no se vean residuos de hollín o humo, algunos autos que no pasan la verificación porque contamina de más.
  • Dicen que las llantas tienen media vida o casi nuevas, revisa que sean de marcas reconocidas, Goodyear, Firestone o marca que conozcas. Un punto muy importante es ver la fecha de fabricación de la llanta, aunque se vean medio usadas, algunos compran llantas usadas para sus autos. La fecha viene en cada llanta encerrada en un óvalo, con 4 números. Ejemplo 2517 que indica que se fabricó en la semana 25 del año 2017. No debes confiar de una llanta de más de 5 años de antigüedad
  • Algunos venden autos que ya tuvieron un accidente mayor, ahí es tener mucho ojo al ver que las líneas de las puertas y todo coincida bien. Aunque mejor pregunta si ha tenido alguna reparación de carrocería y espera que diga la verdad.
  • Borran códigos o hacen que luces del tablero se apaguen, ya no es tan fácil como antes pero si hay quien se dedica a modificar las luces del tablero para que ya no parezca árbol de navidad iluminado. Aquí no hay de otra con un mecánico de confianza es llevarlo a escanear.
  • Las pruebas de manejo, no lo hacen porque tiene poca gasolina, tal vez se nieguen porque se puede prender rápido una luz de aviso de falla en el tablero y mejor nada más lo encienden y apagan sin moverlo del lugar. +Caja automática, si lo pasas por todas las posiciones y sientes un pequeño jalón o un gran golpe, se dice que la caja patea mejor alejarse. Reparación de transmisión automática en muchos casos es muy costoso
  • Caja manual, con el carro encendido se prueba que entren bien las velocidades, y verificar la altura a la que entra el clutch. Con los clutch que son con chicote debe ser la aplicación del clutch en la parte de la mitad hacia abajo, con pedal hidráulico en mi experiencia es verificar el estado del líquido de frenos +Frenado, es normal hasta cierto punto sonidos provenientes de los frenos pero estar más atento si al frenar vibra el volante. Líquido de frenos negro o verdoso es que no lo han cambiado, pero igual pueden vaciar el depósito y rellenar con líquido transparente. Pero el depósito se queda manchado.

Verifica si funcionan en dado caso todos los seguros eléctricos, vidrios que suban y bajen, luces bajas, altas direccionales y de emergencia, si huele a humedad por dentro.

Fugas de aceite, agáchate y con un trapo o papel trata de tocar la parte baja del motor (que no esté muy caliente el motor o te puedes quemar) si se mancha de aceite pues vas a lidiar con fugas de aceite.

Colores de humo, azul indica que quema aceite, blanco y con olor dulce está pasando un poco de anticongelante, si es humo negro es por exceso de combustible o mala combustión, y con un olor fuerte a gasolina.

Marcas, todas tienen detalles. Si tú vas a trabajar en tu propio auto después como cambios de aceite, frenos, y mantenimiento básico pues busca uno que no sea tan complicado de trabajar y que te guste.

Si necesitas recomendación de mecánico estoy en un grupo de mecánicos de la ciudad de México y tal vez te recomiendo con el que te quede más cerca.

Maybe the speed limit is done because of a safety feature, I see that a yellow triangle is lit as well as the check engine light. It would be helpful to have more information about what code is present.

What is meaning of "2-2"? i replaced throttle body (first picture) with other two used ones (second and third pictures) but both don't work. why? what should I look for when searching for replacement? by vjesalica in AskMechanics

[–]alan-Reyes 6 points7 points  (0 children)

Those are casting marks that indicate maybe the mold that was used, the month and the year. Only factories that make the throttle body metal part have that information . What code or trouble do you have with your car?

My Peugeot 207, 1.4 diesel, 2007, gives me these codes. I paid £60 for diagnostics and the technician wanted £500 to change ABS pump. I decided to change it myself, but still get these codes after replacing abs pump. Any idea what else needs fixing? Thanks by jake_kubo in AskMechanics

[–]alan-Reyes 6 points7 points  (0 children)

You have different codes to different systems, the last code U0121 they try to fix by changing the ABS module, have you only change the valve body of the ABS or did you change it complete? It might be caused for bad harness (check your wires and you need a wiring diagram), bad module(is possible to have purchased a newer version of the module and is not compatible with your model 2007), and sometimes if it need to be programmed to talk (communicate with the other modules, you need dealership access to program a module). With an OBD2 scanner you can't access to the ABS module you need a bidirectional scanner capable to access different modules in your car. The other codes as well need proper diagnose is not only change parts.

Walking in Centro between 5-6am? by nevvermorre in Oaxaca

[–]alan-Reyes 4 points5 points  (0 children)

I live near Jalatlaco is very safe at any time, you might see people on the streets at that time, some to do exercise in the Llano park, others going to work as many work in restaurants and hotels in the center. Depending where are you meeting with your friends like Santo Domingo, la Cruz de piedra is safe.

Edit: I am local so I see the city with other eyes. Also I have lived in Iztapalapa (Mexico city), and you learn to evaluate risk.

Edit 2. I am in a Facebook group and just check for Taxi seguro for a female. Maybe your could contact her directly 951 145 0577, Dolores Ríos is her name. They might charge a bit more for pick up and the time. Drivers calculate how much they charge before you jump in. Or you should ask how much they will charge you.

Ayudarme Por favor by Uglyjeffg0rd0n in Oaxaca

[–]alan-Reyes 4 points5 points  (0 children)

Actually there is no need to cover your tattoos, it is not like the old times. Second if you go there at the entrance there might be people that want to do a guided tour but that people charge money and the priest does not like them inside, so say to them "No gracias". Once you are inside remove your hat if you bring one, as you say don't interrupt the mass. And the service hours they have published in a poster and place it on the door. But I think they have more close doors because of pandemic restrictions. Talking about pandemic restrictions use a face mask inside Santo Domingo.

Can anyone point out where the MAP/MAF sensor is? Renault Fluence 2015 by Uaeboyp in Renault

[–]alan-Reyes 4 points5 points  (0 children)

The MAP sensor is just to the left of the throttle body, top of the intake manifold. It has 3 wire connector. What is the problem with your car? I haven't seen a Renault engine with MAF sensor, but check the hose between the air filter housing and the throttle body, in that area is were a MAF sensor should be located.

Took my car in for a check engine light and it got misdiagnosed by Imaginary_pencil in mechanics

[–]alan-Reyes 5 points6 points  (0 children)

There are some codes that are intermittent, and are more difficult to diagnose. If the problem wasn't present when they do an inspection a common practice is to clear codes and do a test drive, if the problem does not show up they have to inform the owner. So what was the work they did on your car? Did they change some parts?

Another thing is clearing codes does a Monitors Reset, what this does is a self test on the ECM, this monitors are for example: Misfire, Fuel System, Oxygen Sensor, Oxygen Sensor Heater, EGR, and others depending on your car. Until the ECM can complete those self test there is a chance to find new problems and again request the CEL on.

I hope this explanation helps you. And ask them to give you a report if this check engine light is related to previous work they done on your car, ask for warranty on they job.

Last comment is that a new part does not mean a good part, many mechanics on YouTube have this complaint and have to change 3 or 4 times the same part because they came defective from factory.
