If you are referring smaller air outlet on the cam cover of the engine, it would not add HP. You can add a little HP by making the engine "breathe" better by having better air filters like the washable cone type ones found in car shops. Another is by ensuring you are getting cold air. Others would put covers on one side of the air filter so the warm air from the engine will not go back to the engine. Other extreme ways are getting a cold air intake and adding turbo but may need further modification and tuning to make it efficient.

59 reg Mondeo 2ltr petrol hesitates on light excelleration when engine is warm fine when choke is on , otherwise car runs fine any ideas ?

check all the breather pipes around the intake check for air leaks, failing that and there are no leaks take the air intake pipe off and check to see that its clean and you should see a pin hole in the butter valve on the top. if fine just give it a clean with some carb cleaner and get any black rings out and soot off it so it like new, put back together. failing that and still the same then it might be a air leak from the gasket to the engine you can check this with the carb cleaner run the engine and spray over the manifold and listen for the engine pitch to change or cut out if it cuts out it's definitely were the problem is, you can use this to find an air leak in pipes as well.

1965 corvette fuel pump breather

It is a diaphram pump with a rubber diaphram. The rubber has more than likely dry rotted letting the gas go through it. When you take it off, there is a "lifter/pushrod?" that go's from the camshaft to the pump. And it will slide down, but there is a cover that holds it in. So it shouldnt fall all way out. When you install the pump pick the shaft up and make sure the fuel pump arm slides under it before putting it in place. Also make sure and lube the arm and lifter real good with duralube or another soft grease or at least lots of oil.
Start and run your car at least once a month and that will keep most of the parts from dryrotting as bad. Engines are made for running, not sitting.

I hope this helps.

Where is the breather filter on a 1994 ford taurus?

If you mean the crankcase breather filter, I've looked into this, but I haven't found any reference to this existing on a 1994 Taurus (at least with a with a 3.8L engine), except for some online parts companies that list it for the 1994, but either they're wrong, or if there were 1994 Tauruses that have a breather filter, I suspect it's for an engine other than the 3.8L. It's used on earlier Taurus models, but only up to 1991. Some people say the PCV valve performs the function of the earlier breather filter, but I don't see how, since the PCV valve just opens and closes, and does no filtering once it's open. On one web page where breather filters are discussed (, it's said that adding one to an engine that didn't come with one, doesn't help increase horsepower or mileage, and can bring in air that's not metered by the MAF, which can actually reduce horsepower and mileage.

95 saturn sc2 breather

It is an air intake silencer. It quiets down the motor when you are throttling up.

Cutting out

Its more than likely a vacuum leak, basically air is entering the charge system that hasn't been metered by the Mass Air Flow Sensor.

What you can do is take a can of WD-40 and lightly spray your intake plumbing from Filter to Engine and see if the idle RPM changes. Don't spray directly onto the surface close enough that the liquid collects, just mist it from about 1 to 1-1/2 feet away slowly to see if you can pinpoint the location where the air is entering the intake system and then tighten up the connections if its at a joint, or replace your parts if there is a hole, for instance in a rubber piece.

I don't know how modified your car is, but if you have other supporting modifications to your car, but if you maxed out your stock Throttle Body (Which is highly unlikely if thats the only thing you've done to your car), you probably need to upgrade your ECU and possibly your Camshaft.

Also, if I may make a suggestion to you about your modifications to your car. If you've done all of this intake work, with no other supporting mods. You aren't going to get very far as far as Horsepower, Throttle Response, or Torque. You only need to upgrade how easily the air can get into the engine if you start getting into some Head-work, some light-bottom end work, and a very good exhaust. The most you'll see out of these modifications is 10-15 peak horsepower, and you probably actually lost some throttle response. I recommend you put the car back to stock and start upgrading the engine from the other end starting with the exhaust. A set of headers, a free-flow true-dual exhaust and a mild camshaft will do absolute wonders for Horsepower, Throttle Response, and Torque-band, not to mention if you do all these things, at that point you could start adding some intake upgrades.

I hope I didn't offend ya by this post, I'm just truly trying to help ya man from a hardcore gear head. Hehe

Installing a chrome engine dress up kit 79 chrysler cordoba

I have done this with my '79, so yes it will work. Although my car is a 360 four barrel, the external engine size is identical. The black box on the stock air cleaner is the "Electronic Spark Advance" computer. It replaced the more well known "Lean Burn" as the ignition/fuel management system. Since you will be disconnecting and discarding the ESA due to the air cleaner change, another ignition system must be installed to replace it - if someone has not already done so. I used a Mopar Performance electronic ignition system-still available for about 200.00. This will not hurt anything. The chrome valve covers fit right on. However on my car, the vacuum amplifier bracket was attached to the right side value cover which I cut off the stock cover and screwed into the chrome cover. I sealed the screw holes with gasket sealer. I do not know exactly what you are referring to regarding the cover connecting the value cleaner to the crankcase breather. There is a hose from the breather which connects to a fitting on the air cleaner. This hose allows the crankcase to vent into the carburetor during wide open throttle conditions when the engine vacuum-operated PCV cannot function. I do like the chrome effect even if it does require more care and maintenance. Good luck!
