Well if you only put 5qts in you might want to check your level, I put 7 qt in.

 

And if you put 7 quarts in, you will do more damage to that engine, -long or short term. Running 7 will froth your oil, - as soon as your @ operating temp. Keeping your crankcase over filled will blow the gaskets and eventually smoke the engine way before one would last following your manual.

Don't do this, - never overfill the crankcase in a modular engine. They DO NOT take that well. Use 6 qrt's per manual , always. Running at 5 qrts won't hurt it, - any IMO. Just try to keep at 6 if it uses oil. And use a Motorcraft PCV valve so she can circulate by design. Other 3rd part valves are a , -one part fits all application, - don't use 3rd party when it comes to your engines PCV valve as well. 3rd party lacks proper margins and restricts flow.

Be good to your engine

 

Hey jbrew, not saying your incorrect at all, but just keep in mind the only thing that really constitutes a dangerous overfill and will actually cause those conditions to happen would be to fill one up to the point the crank is in a bath of oil while the engine is running. Pretty safe bet on an engine built for the general public one quart's not going to do that. Not saying it's good practice to overfill it, just sayin!

 

Well, nutshell is, -air can get to your bearings, - engine wear, you can hurt her some. Sure, over filling by two quarts is worse than one.

To dangerous IMO, -@ a quart over. All you have to do is get the engine in a position where the crankshaft whips the oil. As soon as that happens, it's going to aerate (enough or some). The Crank doesn't have to be totally submerged (from front to back) for cause and effect..

FTW = -don't do it. lol.

 

Agreed!!

 

It isn't over filled at all it actuly doesnt even fill it all the way on mine.

 

It is the dip stick that is off. If you put more than 7 quts in, it is overfilled, regardless of where it shows on the stick. Correction, 6 quts for your year.

 

Unless the previous owner put an oversized oil pan on it........

 

As stated...unless there's been an oil pan change (and that would be the only reason), if you're putting 7 quarts in an '98 and it's not showing full on the dipstick, you have a dipstick problem...not a low oil problem.

If you have stock oil filter and stock oil pan, next time you change the oil you need to add 6 quarts, start it up for a few, shut it down, and let it sit for a few more. Now check the dipstick...where ever the oil level is on the dipstick is full regardless of what the markings say. Mark this level as your new "full" position.

 

You mean 98 I hope - the 08 5.4 holds 7.

 

Well I also have a rare engine, I am finding out, and here is the info off the serve I use for work.

Engine Oil
A/T Models 6.3L (6.7 Qt)

M/T Models 6.0L (6.4 Qt)

NOTE: Listed capacities are approximate. Check fluid level after filling.

 

My son in law has a 98 with a 4.6, and 6 quarts brings the oil up about halfway between the ADD and FULL lines. My 03 V-6 is the same way.

 

That's really weird that you would have different oil capacities for different trannies with the same motor. What is your "rare" engine?

 

Its a 4.6l vin 6. the more common ones are vin W and 9.

 

6 = Windsor.
W = Romeo.

Orientation - Windsor along with the 5four blocks. Nothing especially different between Romeo and Windsors besides the valve covers. Heads are slightly different for the 4.6L's but all are still interchangeable, - including the 5.4L's.

Capacity's have never changed for the any of these modular blocks from the factory. That goes for standard oil systems and remote, which both include the 6.0 quart crankcase, same pan and oil cooler on the block.

You can lookup "Babcox" = Engine builders for Ford Modular engine changes. Specifically look for, - "Rebuilding the 4.6L by Babcox". If you want to learn about Ford history and/or modular differences.

Yea, here's just one article to get you started -
