Need a engine diagram for a 2.8 ltr v6 showing rear main seal

Hi. The output speed sensor for the speedometer is located on the right hand side. On the rear tail cover, near the rear main seal.

Don't need a diagram, you have to pull the transmission to replace the seal. It is the seal in the engine block that goes around the crankshaft output to the transmission.

This may be from excessive pressure in the sump from blow-by from the compression process . It is from a blocked PCV valve that is not equalising that pressure. I have also known oil leaks to happen because the rear main bearing cap is leaking oil past the join around the bolts (loose) or no sealing compound used in assembling the rear main bearing.. I would look at the PCV valve as it is the cheapest test first.. Check that the oil is not coming from the front gear box seal or torque converter seal.

You don't say what engine it has. The 4-cyl was a better than the V6 for oil leaks.

The V6 had oil leaks from

-rear bank cam cover gasket

-distributor o-ring seal

-oil filter bracket o-ring seal

-crankshaft nose oil seal (less common)

-rear main bearing oil seal (expensive, just leave it)

The 4 cyl leaked oil from

-distributor o-ring seal

-camshaft cover gasket

-rear main bearing seal (expensive, leave it)

You can leave the engine in, just drop the transmission and replace the seal from under the truck.

The next, I "bid" it. Good luck.

no. honda had a problem with the balance shaft seal poping out,they made a retainer arm thats in stalled when the new seal is installed, you must remove the timing belt to get to the seal, here a diagram. hope this helps.the arrow points to the shaft where the seal is,

Ford V6's - rear bank of cylinders are 1 - 2 - 3. Front bank are 4 - 5 - 6 starting from passenger side (front) of engine.
Your firing order is
1 - 4 - 2 - 5 - 3 - 6

You're welcome.

No it does not. But there is a crank shaft seal in the rear. Check to see if the intake manifold is leaking from the rear as well.

In order to replace the rear main seal u have to pull the transmission out to access it, u will need a special seal installer tool to install the new rear main "full circle seal", it u don't use the special ford tool the seal will leak again, also if there is a groove worn ion the crankshaft the crank must be repaired or replaced or the or the seal will leak again, so this is avery diff job, a 9 on the scale of 1-10 with 10 being the mos difficult.
