Ticking on 1990 CrownVicLTD

When ever I press (even slightly) on the gas pedal... I get "Tick Tick Tick Tick Tick... etc." When I release the gas. It's normal engine sounds. It's hard to explain. It's not an overly loud noise, but I would still like to know...

Thats what I'm thinking. It could be your oil lifters BUT before you go and order those give it an oil change with some good oil(preferably synthetic) and see if the ticking goes away after driving it for a while after the oil change. If not then yeah get some new lifters. DSMs are notorious for that. Mine starts to tick about the same time I'm due for a change so I just call it the you need an oil change sound.

Owning a DSM is like having retarded kids. You get angered and frustrated by them yet you love them to death.

Newyorker was the only one making fun, but trying to help at the same time. All other posters were trying to help you.

I doubt that doing a burnout one time would cause the ticking in his car unless he has done more than one burnout of that we don't know. The other solution i would have for this is to repace the oil lifters or it may indeed be valve tick.

This is hardly enough information to diagnose an engine with a major hardware failure such as a lifter problem. All we know, thus far, is that an oil change did not solve the problem. You could have many things wrong with the engine in a spectrum of insignificant to major. We'd need more information that this to assist in providing an accurate diagnosis online.

I have not seen anywhere that tells us how many miles are on this engine. I don't even see any information on WHAT engine we're talking about other than it's a '90 Crown Vic. and it has a V8. What is the history of the car? What conditions has it been driven under for most of it's useable life and how many owners has it had? Does the car burn any oil and has the engine ever had any major work done on it in the past.

As Dodger pointed out, this could be as insignificant as an exhaust manifold gasket that is blown. Do you smell exhaust under the hood when the engine is running? Is the engine quiet at idle and then when you place a load on it (ie....increasing throttle pressure or accelerating in DRIVE) If it is a tick as described, that sounds to me to be exactly what it is. A blown exhaust manifold will cause this exact problem and it can make the engine sound horrible if really bad. If not manifold, could be a leak near the manifold.

With the info. provided, look for the simple things first!

Well she's got 252,000 KM on it, the engine idles nice and quiet. It was used by an older man, only in summer on highways mostly. It has brand new brakes(irelevent I know) and exaust system in. If I'm cruising down the road with just a feather throttle I don't hear it. When you increase throttle it gets louder and seems to be less noticable in higher gears.

Sounds to me like I'd be checking that exhaust manifold(s) and see if I have any leaks. Since it's a V8, check both sides and see if you can smell exhaust under the hood when you increase the throttle pressure and accelerate the engine. Also, stand at the front of the car with the hood up and manually gun the engine at the throttle linkage and see if you can hear where the noise it coming from. I am not 100% sure what you mean by a "tick," but a tick tick tick to me is more of an exhaust leak noise. Lifters are going to be an internal noise but I guess they could tend to make more of a ticking noise, but usually I would describe it as more of a "slap" or "knocking."

Either one of the problems could be exacerbated by placing a load on the engine or increasing rpm. Sometimes lifters will be worse at certain temperatures such as making noise when cold and lubrication is not optimal vs. they shut up when they get hot. Exhaust would be all of the time. Lifters could be, but depends on the problem.

An example of this is my 2002 Trans Am with the 5.7liter Ls-1 V8. When I start the engine cold, she likes to have a couple of lifters talk to me just ever-so-slightly. It is a known design flaw of that engine but does not hurt it a bit. Once I have driven it a mile or so and have lubrication optimal, she shuts right up and has no noise. I have checked with the folks in the know and they say normal. I don't worry about it, that being the case.

At this point, you'll need to do some troubleshooting on your own and perhaps have someone that knows cars take a look. There is only so much we can remotely do online. Good Luck with it!
