It's for my 2005 ford f150. It's a 4.6 2 valve with 45k miles from a junk yard.

I just spun a bearing on my truck with 165k miles.

Before I toss this new engine in should i check anything for wear? Is there upgraded I should do to this engine while it is out of the truck to help with the longevity of this motor? Ie high flow oil pump, cams Ect?
I've got the time and some cash to put in some safe guards.
Or just plug her in like it is?

(On a side note I posted yesterday about swapping in a 2011 4.6, I've decided against that now, bought one the same year)

 

Okay so you purchased a used 2005 4.6L right.

The most important thing to do right off, IF you haven't yet is to compression test the engine before wrenching it home. If it doesn't pass, take it right back, you definitely don't want it, - low miles or not.

 

Yeah good call.

Ill toss a starter and battery at it tomorrow and check.

If like to toss an upgraded oil pump on it. Not sure if that would be over kill though.

 

Well that won't work. Starter won't bolt up to just the motor. Need to have the tranny installed to bolt starter and check compression. I guess I'm just tossing the engine in as is.

Unless there is another way to check compression?

 

Sure, just stick an impact on the crank.

You have an impact ? What else ... An electric drill could work, but you'll need something as powerful as a Milwaukee Hole shooter or the Milwaukee Right angle. Those two right there have the proper torque and gear ratio for compression testing. The important thing it to test each cylinder the exact same way.

Bumping the starter is choice but not necessary.

Do you have the Ford CT chart ? Have you done this before ? I may be able to help there if your not familiar with it. (?)

 

A breaker bar works just fine unless your a weakling..

 

Just use any bolts and nuts that fit and bolt the starter to the plate/shield, also bolt the shield to the block if not already on an engine stand

 

A breaker bar won't turn the engine over fast enough to get good compression readings.

 

Here yuh go-

Compression Test—Compression Gauge Check

1. Make sure the oil in the crankcase is of the correct viscosity and at the correct level and that the battery is correctly charged. Operate the vehicle until the engine is at normal operating temperature. Turn the ignition switch to the OFF position, then remove all the spark plugs.

2. Set the throttle plates in the wide-open position.

3. Install a compression gauge such as the Compression Tester in the No. 1 cylinder.

4. Install an auxiliary starter switch in the starting circuit. With the ignition switch in the OFF position, and using the auxiliary starter switch, crank the engine a minimum of five compression strokes and record the highest reading. Note the approximate number of compression strokes required to obtain the highest reading.

5. Repeat the test on each cylinder, cranking the engine approximately the same number of compression strokes.

Compression Test—Test Results

The indicated compression pressures are considered within specification if the lowest reading cylinder is within 75 percent of the highest reading. For additional information, refer to the Compression Pressure Limit Chart.



If one or more cylinders reads low, squirt approximately one tablespoon of Super Premium SAE 5W-30 Motor Oil, XO-5W30-QSP meeting Ford specification WSS-M2C153-G on top of the pistons in the low-reading cylinders. Repeat the compression pressure check on these cylinders.

Compression Test—Interpreting Compression Readings

1. If compression improves considerably, piston rings are faulty.

2. If compression does not improve, valves are sticking or seating incorrectly.

3. If two adjacent cylinders indicate low compression pressures and squirting oil on each piston does not increase compression, the head gasket may be leaking between cylinders. Engine oil or coolant in cylinders could result from this condition.
Use the Compression Pressure Limit Chart when checking cylinder compression so that the lowest reading is within 75 percent of the highest reading.
