3rd & 4th Generation (1992–1996 & 1997–2001)Toyota Camry Discussion for years: 1992-1996 & 1997-2001
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
Hi, I have a 1998 Toyota Camry CE 4cyl, I turned it on today I heard a ticking noise. When I accelerate the ticks become much faster. What do you guys think is making that noise? I was using Castrol GTX 15-W40 oil. I changed the oil, and used 10W-30
and it's still doing the ticking.
Does it occur even with the car in Park? If so, try to use a mechanic's stethoscope, dowel rod, or rolled-up newpaper to isolate where the tick if coming from.
Yep, it happens all the time, it's non stop. I used an OBD2 scanner and one of the trouble code said P0171 system too lean. I used a stethoscope and I couldn't really locate the sound.

You didn't mention that your CEL was on. Is it? And what were all the trouble codes?
Were you at least able to narrow down where the sound wasn't? Like, alternator, A/C compressor, under valve covers, under timing cover, top of engine, bottom of engine, left side, right side?

Have you checked your oil level?
There was no check engine light on, that was the only trouble code was the one i mentioned before. Oil level is perfectly fine, I changed the oil today. The sound sounded like it was either coming from the left of behind the engine.

Lots of possibilities to in that area -- could be the alternator, A/C compressor, P/S pump, or one of the idlers behind the timing cover.
Can you pop off the passenger side tire and the wheel-well access cover (behind the wheel and kind of to the right-ish -- held on with a couple of 10mm bolts)? That might give you better access to things with the stethoscope.

I'll try that soon, I also have this feeling that it could from the oil pump. On the OBD2 scanner what would it come up as if there was low oil pressure?

You don't get a code for low oil pressure. If pressure gets obscenely low, the "oh shit" oil light will come on, but things have to be pretty bad to trigger that.
OTOH, the oil pump in these rigs is very simple and extremely rugged -- while they'll often leak oil due to hardened seals, they essentially never fail outright. Low oil pressure in a Camry generally is due to worn internal clearances (in very high mileage or abused engines) or sludging in neglected engines.
My Camry has 280,000 km on it. I bought it used when it had 238,000 km on it. So it's been taken care of very well for a while. Even before I bought it was in really good shape.

OK, until proven otherwise, we'll assume the engine is in generally good shape internally.
If you wish to check the oil pressure directly, you can always unscrew the sender (it's driver's side front on the engine -- dead easy to get to, but you'll get to buy or borrow a special "oil sender socket" to remove it), and connect up an oil pressure gauge. Renting or borrowing one from an auto parts store would be the cheapest approach, although the higher-end Harbor Freight unit isn't half bad, and not terribly expensive.
Do you happen to know when the timing belt was last replaced, and if any of the other nearby components (water pump, idlers, tensioning spring, oil seals) were replaced?
Sorry I don't have a solution, but I wanted to chime in...
My car has the exact same problem, although it seems to exhibit the noise mostly when the car is in warmer weather, or has been previously running.
I first noticed it when driving on a small street next to parked cars... the noise echoed back and was really loud.
