Hi,I have 1995 1500 chev suburban,just the other day I started to hear this low ticking sound,i checked the oil i poured 2qrts.of oil in. After a while my oil needle kept jumping and the check guage lite kept coming on after I put oil in,mind you I just got an oil change 2wks. ago what do I do? jgchevy1995sub.

IF you did not add oil, then you have a leak that is allowing antifreeze to leak into the oil. The oil will look milky. The coolant level will drop. This wont be a cheap repair either.

I have never heard of an engine noise being described as a tick tack rattling noise. (I assume you mean Tick Tack candy/breathmints?) \

Either way, if it doesnt start, but just makes a rattling/knocking sound, I would ask you did it just quit on you and not restart? Or did it get you where you were going and then would not start when you were ready to leave? If the answer to the first question is yes, then you are likely facing a broken timing belt. The sound you hear are the valves coming into contact with the pistons when you are cranking the starter. This is a bad sound. Lets hope your answer was no to the first and yes to the second. Are you sure have gas? I cannot tell you how many times people have told me "It just won't start!" only to pour a gallon of gas in and varrroooom! What about oil? The tick tack sound just doesn't sound like a healthy engine sound in my head. Do you have oil in the engine? Does somebody hate you enough to drop nuts and bolts into your intake manifold? That would sound like tick tacks. BIG GIANT tick tacks, but tick tacks nonetheless.

When you start the car with cold engine the oil light indicator is on even after the engine started?
If the sound comes from the engine itself you could check the oil level with cold engine before start.
If oil level is ok ( between low and maximum marks on the dipstick ) then could be 3 posible causes:
1. Bad oil
2. Faulty oil pump
3. Worn camshaft bearing, worn crankshaft bearing, or faulty piston bolt.
It may help if you bring on some more details like since when is making that noise, in what circumstances appeared and so on.

Ticking sounds like a dry lifter, when was the last time you changed the oil and filter? Humming sounds like you need a tire rotation because of uneven tire wear.

The ticking sound is a valve ticking probably sticking if your car doesnt start now its probably cause the valve dropped and fell in the cyc and now froze the motor i would recommend not trying to start it again or it could harm your car more ....hope i could help Shane

try checking the oil sometimes when oil is low u will hear a ticking sound, it is important to maintain all fluid levels at appropriate levels. if ur oil isnt low u could have a time bomb on ur hands.

Definitely change your oil every 3 months or 3000 miles. After you change it add a half cup of Lucas engine oil suppliment when the engine is hot.
If if goes away you know it's cam or lifter issue. If it doesn't the ticking you hear may simply be your fuel system.

Check fuel pressure and fuel flow, If the pressure is lower than what is recomended injectors will not function correctly , no start condition (trys real hard though)

Low oil, lifters, cooling fan, serpentine belt

hi try getting a service done make sure they use genuine toyota oil and filters

cheers
