SOURCE: need to replace the starter

nope... it's on the bottom of the motor... or rather mounted there... i'm not familiar with that car... is the motor in sideways or front to back.... either way... the starter drives a gear on the back of the motor located where the transmission is bolted onto the motor. so look at that spot on either side of the motor on the bottom.. best to just lay on the ground and look up at the motor... unless you have car ramps you can drive the car up on. be sure to unhook the battery... usually two bolts hold it on.... drop the starter... unhook the cables and make sure you put them on the new starter the same way... mount the starter back on and tighten the bolts and you are good to go.

you do know for sure the issue is the starter ?

SOURCE: car will not start, starter will not engage

REMOVAL & INSTALLATION

  1. Disconnect the negative battery cable.
  2. Raise and support the vehicle safely.
  3. If necessary for access, remove the splash shield.
  4. If equipped, unfasten the flywheel inspection cover bolts and remove the cover.
  5. Label and detach the electrical connectors from the starter.

Fig. 1: Unfasten the starter motor electrical connections. You may want to tag them first to avoid confusion

  1. It may allow more room it you remove the right side cooling fan.
  2. Remove the starter-to-engine bolts, then carefully lower the starter from the vehicle.
Fig. 3: The starter is attached to the engine with 2 mounting bolts (see arrows)

SOURCE: Excessive Oil consumption, 1995 Bonneville Vin K 3.8

The PCV valve gets it's vacuum from the plenum itself. Some 3.8L have different types of connections on the top of the valve (electrical or mechanical), but none have a vacuum line on them.

If you replaced the lower intake gaskets, it is very likely they crushed around the intake bolts. This will cause oil to leak into the intake and pool in the recesses of the lower intake. You are also likely to be leaking anti-freeze.

This is a very common problem with OEM gaskets. After market gaskets made by Fel-Pro have metal rings in them specially to stop this problem. They are available at NAPA and other stores.

SOURCE: I need to remove the upper intake manifold plenum.

There are no fasteners inside the plenum, The electrical connection for the injectors is very tight due to a rubber ring gasket the seals the injector assembly to the plenum. Carefully push down on the electrical assmbly while prying up the plenum. You also may have to remove the thermostat and hose. I've done this 3 times on my ladies 96 Yukon.

What are the correct rockers/lifters to order when replacing ALL of them on 97 nissan pickup?
A normal sohc 4 cyl. has 4 intake and 4 exhaust.
That motor has 8 intake valves (2 in each cyl.) and 4 exhausts.
I thought all the lifters were the same ,but if what you say is correct you need 4 intake front ,4 intake rears and the 4 exhaust,if they were all bad.

Were is that camsensor located
Fred is correct when he says it on the left side kind of in the middle. In any case below is a picture that should help. I know the power steering pump does need to be removed/repositioned in order to replace but I have myself been able to replace it without having to remove the upper intake to do it. also if you're getting a trouble code of P0300, I would look into the crank position sensor first as that has more of a job as far as how the car is timed and misfires. hope this helps.....

Water leaking from rubber elbow on intake manifold passenger side of motor
It could be the intake gaskets, or it could be that the upper intake is starting to fail. Both are common problems. How fast are you losing coolant? If it's fast, then it may be the upper intake. Also, how many miles are on it, and has the upper intake been replaced before? It may be due for a new one.

Anyway, the procedure for doing the gaskets and for replacing the upper intake are exactly the same, except that if you replace the upper intake, you put on the new one instead of reinstalling the old one. I've done this with mkaake over a couple of days. There's a lot to remove and replace, but nothing that's especially hard to do. Have a service manual of some kind on hand, and do some serious research before you take it apart.

Parts you'll need:

1) Upper intake gasket set
2) Lower intake gasket set (make sure it's the new upgraded version, with metal inserts)
3) Plastic coolant elbow (it's under the alternator, and rarely comes off in one piece. It's also a dealer part, so if you're doing this on a Saturday and the dealer is closed... you get to wait until monday to put it back together - unless you get one ahead of time)
4) Fuel injector O-rings (might as well replace those while you've got them out anyway)
5) Carb/TB cleaner - several cans (you'll want to clean up the upper and lower intakes, and the TB while you've got them off)

That's all I can think of right now. I also don't know prices. Maybe someone else will have that info.

Spark plug location in a 2001 ford escape
Need to remove upper intake manifold to reach valve cover close to firewall.
1) The location of spark plugs 456 are under the plastic shield in front of the engine. It takes an 8mm socket to remove the three bolts holding the shield once the shield is removed you will see a coil for each spark plug. Use the 8mm socket and remove the coil and rubber boots. You will now see the spark plug (note there are not any spark plug wires).
2) The location of spark plugs 123 are located to the rear of the eng. You have to remove the air intake manifold in order to get to the spark plus. Remove the throttle wire then remove the other items on top of the intake manifold.
