When did Ford stop using Slinger on Crank block?
When did Ford stop using Slinger on Crank block?
In April 1983, Ford switched to a one-piece, rear seal, so the slinger on the crank was eliminated along with the groove in the block. The new block was an E3AE casting.
How many rods are in a Ford 4.0L pushrod V6?
Ford has made a number of changes and improvements to the 4.0L since it was introduced. Engineers revised the block, changed the heads, played with four different cams and used four different rods, so it would take about 10 short blocks and even more long blocks to rebuild all the combinations exactly the way Ford made them over the last 11 years.
What kind of casting is a 2001 Ford FWD block?
The 2001 FWD block is a 1F2E casting that has the short mains, but it has six studded main bolts that are used for the stud girdle that has a windage tray in the center. This girdle is much thicker than the earlier designs, so it clears the crank and rods without the spacers that were used under the windage tray in 2000.
Is the 1999 FWD block the same as the 1998 block?
The 1999 FWD block was an XF2E casting that was identical to the ones that were used from 1996 through 1998. The bolt holes were all the same and this block still had the deep mains, so it can be interchanged with the F68E and F78E castings.
How can you repair a cast iron head and block?
With cast iron heads and blocks, 80 percent of cracks can usually be repaired with iron or steel pins or tapered plugs while 20 percent of cracks will require furnace welding, flame spray welding or brazing.

Which is harder to repair aluminum head or block?
Small porosity leaks in aluminum can often be easily plugged with a single pin or tapered plug. Cracks in an aluminum head or block, on the other hand, are much more difficult to repair by pinning because aluminum is a softer metal than cast iron so the pins and plugs can’t achieve as much “bite” as they do in an iron casting.
What’s the best way to repair an engine block?
Another cold repair technique that can be used on areas that are outside the combustion chamber or on exterior casting surfaces is to fill cracks with a high temperature epoxy. Many epoxies can provide a strong and long-lasting repair. Metal-filled epoxies may even be drilled and tapped to restore broken bolt bosses.
