What kind of oil does a Ford 302 hold?

I have recently acquired a 302 out of an 88 mustang with 75000 miles on it. When first started it will hold 50 PSI oil pressire. After it warms up the pressure drops to about 25 PSI driving, and about 15 PSI at idle. I am using 10w30 oil.

What should oil pressure be on Ford muscle car?

If you want to see a slight increase in oil psi, just bump up your idle speed a tad. Your oil pressure is a bit low but not off the chart low for a stock motor with 75k miles.

Where was the original Ford 302 engine made?

Optional was a four-barrel version rated at 230 hp (172 kW) at 4,800 rpm. The 302 was manufactured in Windsor from 1968 to 1978. This is where the 302 Windsor name comes from. In 1970, the manufacturing of the engine was moved from Windsor, Ontario to Cleveland, Ohio.

What’s the difference between spark plugs on a Ford 302?

Spark Plug Size Differences: The 302 came with (2) different size spark plugs. The large plug (left) has a 13/16 hex 18mm thread, and the smaller plug (right) has a 5/8 hex and 14mm thread. Ford switched to the smaller base spark plug in 1977 with the appearance of the D8OE heads.

What kind of oil do you put in a 302?

As Mavman said – weight of oil depends on bearing clearances. I go by old school method – 10psi oil pressure per 1000 RPM. If you expect to max out at 5000 RPM I would want to see 50 psi but not less than 25 psi at idle. 10W30 works pretty well with normal 302 clearances which would be around .002″.

When did the 302 cubic inch engine come out?

The 302 cubic inch engine was introduced in 1968 to the Mustang. Although it is a derivative of the 289 mustang, some parts are not interchangeable. In fact the block of a 289 cannot be used without some machining.

Can a 289 engine be used with a 302?

In fact the block of a 289 cannot be used without some machining. Since the 302 crankshaft is larger, it requires a notched out section in the engine sidewall to allow the connecting rod end bolts to pass. If you are unsure of the parts you are using to build an engine, check tolerances carefully.

What kind of gas does a Mustang 302 have?

The Tunnel port has 4 bolt mains and the 302 Boss has 4 bolt mains and is cross bolted as well. All 302’s drank regular gas except the Tunnel port and Boss engines, they gulped premium gas. Of all the 302 engines, only the Boss had solid adjustable lifters all others had hydraulic lifters.

What to do with a high idle Ford Mustang?

This is the fix for a stuck/high/surging idle. Example: You pull up in the driveway or to a stop light with the clutch in and the car idles it self up to 2K or 3K rpms and then stays there, then finaly drops down when it wants to.

Where are the trouble codes on a fox body Mustang?

The large connector contains the self test output (STO) and ground (SIG RTN). The small pigtail is the self test input (STI). You can easily grab your trouble codes, and this will help you diagnose your MIL or “Check engine ” light on that fox body Mustang of yours! Note: Make sure your engine is warmed up before doing these tests.

Can you count check engine light on 89-93 Mustang?

Using The Check-Engine Light (89-93 Mustangs) The 89-93 Mustangs (and the 94-95’s as well as some ’88 MAF equipped Mustangs) will allow you to use a jump wire and count the check-engine light in the dash. The jump wire (I’d use spades on each end) would connect the STI (test input) with #2 pin on the connector, see below:

Can you remove pollution control from an 88 Mustang?

Run the check engine codes. ’88s don’t have a function CEL, so no idea if codes are generated that could be cause of your issues. Removing the pollution control equipment from a 5.0 Mustang is a bad idea. All you have accomplished is to make the computer mad and spit codes.

What causes idle surge on a fox mustang?

The MAF measures the mass of air going into the engine, measuring this helps compensate for air density changes with altitude and even the weather. Try and avoid an open-air filter element in the engine bay, it has been known to cause surging issues on some Fox Mustangs.

Why does my Ford Mustang die at idle?

The car died every time it came to a stop. After driving it with this no idle situation for 50 miles or so, the engine would idle with a surging idle. I ordered the idle bleed plate and installed this and reset the TPS to .98V at idle and followed the directions in the kit about setting the throttle stop.

What’s the oil pressure on a 1931 Ford Town Sedan?

I just bought a 1931 Ford Town Sedan with a 1974 Ford Truck 302 engine. This engine was rebuilt about 4000 miles ago. I am getting low oil pressure readings so I replaced the electric gauge with a mechanical one. At start, the pressure is 40 psi cold. When driving it gradually goes down to 20-25 psi.

When to know if your oil pressure is high or low?

Before concluding that your car has a high oil pressure problem, it is a good idea to first check that the oil pressure gauge is working properly. If the car is on idle and the engine oil is hot – you normally have low pressure. If the engine oil is cold and you rev up your engine, the gauge should be much higher.

What should the oil pressure be at 3000 rpm?

The ideal oil pressure ranges between 25 to 65 psi when the engine oil is warm and 1000-3000 rpm, whereas if the oil pressure reading shows 80 psi or above then there is some serious problem.

What should the oil pressure be in a Ford 302?

You can add thicker oil but the only way to fix it is to replace the oil pump. You can buy the high volume one if you want but a standard one will bring your pressure up just fine. About 10psi at all temperatures seems to be the average. 10psi might not sound like much but it is, going from 5psi hot idle to 15psi hot idle is a bunch.

If you want to see a slight increase in oil psi, just bump up your idle speed a tad. Your oil pressure is a bit low but not off the chart low for a stock motor with 75k miles.

What is the oil pressure in my car?

I am getting low oil pressure readings so I replaced the electric gauge with a mechanical one. At start, the pressure is 40 psi cold. When driving it gradually goes down to 20-25 psi. At idle when warm, it is 5-10 psi at best. no unsaul sounds,
