What Does A Timing Light Do?


Recommended Posts

Hey guys

I bought my first Skyline. R33 s1. My neighbour came over who is a mechanic and instantly noticed my crank angle sensor looked to be at 17deg???? That does not make sense to me.

He suggested I get a timing light.

Can you please tell me what a timing light does? Is it something that is always connected to the car like another gauge?

My car has a turbo back zorst, pod, 10lbs boost, Spitfire coils.

My advice, never let this guy touch your car.

You can never look at a CAS and "guess the timing advance"

hahah thats what I was thinking :P

Thats why i think most mechanics a dumb grease monkeys, they seem to get their trade cert in a kellogs box and know stuff all about cars! They just assume

Orrrr, the bloke knows that Skyline's normally operate with about 15 degrees base timing, so he just wanted to appear like he knew something? Lol.

Nah never mind. What Jez and Mafia said.

/\ this!

if you're not sure a mechanic or someone shouldn't charge much to throw a timing light on it?

have seen one with the cam belt not set up properly where they f'd with everything else trying to make it run?
