Cant find rear sparkplugs

Valve cover gaskets for that much oil i would say rear main seal.

If your sportage has the 4 cylinder engine, there is a plastic cover over the engine that is held down by 4 bolts, one at each corner. Remove the bolts with a 10mm socket and lift he cover off and lay it aside. You will see the spark plug wires and the 4 holes where the spark plugs are. The spark plugs are about 4 inches down into the holes. Be careful removing the spark plug wires, they will be tight, and you will have to rotate them back and forth while pulling up to get them loose.

Open the hood to access the engine compartment. Locate the sparkplugs sitting to the side of the motor. Six wires run to the motor, three on each side.

Twist the rubber boot and pull away from the sparkplugs. This will expose the sparkplug.

Unbolt the sparkplug with a socket wrench. Use a 5/8-inch deep-well socket attached to the socket wrench.

Pull the sparkplug away from the motor. Discard the sparkplug.

Screw the sparkplug into the motor by hand. Make sure it is hand-tight.

Tighten the sparkplug with the socket wrench, using the deep-well sparkplug socket.

Click the wire to the sparkplug wire to the end of the sparkplug. Gently pull the wire to ensure it clicks into place.

Repeat the procedure for the remaining five sparkplugs. Change each sparkplug one at a time.

I dont have scematics avail for this vehicle. Here is some info though. There are three at the front top part of the engine. You will see three black ignition coils over plugs (COPs) with a grey electrical connector connected to it. Onece removed, Below these COPs are the sparkplugs. At the rear of the engine, there are another three COPs. (coils). But in order to get to them, you must remove the intake manifold. its the large black plastic pipes atop the center of the engine heading towards the rear of the engine. This entire unit needs to be removed. This job is about $450-$860 at the dealer or auto repair shops. It's not an easy task!! Hopefully this helps!!

They are located at the center of the cylinder head. V-6: the v6 has two heads, front and rear. In each of those heads (front/rear)at the center, there are 3 ignition coils(black circular units- 6 units total) atop the sparkplugs with an electrical connector attached.

4-Cylinder: They are located atop the engine and at the center. There is a black plate/cover across the top of the engine, remove this to access the sparkplugs. Hopefully this helps

This is a lenghty job!! You would have to remove the plastic engine cover to locate the plugs (cover that has the lexus symbol). There are 3 coils(black squarish units) on the front head and another three in the rear head. You must remove these to access the sprakplugs. Front is very easy!! The rear is difficult, you would have to remove the intake(special tools are needed) to access the rear coils and sparkplugs. hopefully this helps

Its located in the head and accessable through the top of the engine. Very easy too replace!! You must remove the plastic black cover, and you'll notice 4 blk ignition coils. Remove those!! And the sparkplugs will be at the bottom of those shafts. Make sure to use a sparkplug socket, otherwise it will be difficult to take them out of the shaft. Hopefully this helps!!

there in the back where you cant see.you just got feel them some times its easer to do them from underneth

under the trunk lip rear seat

Youre going to have to take the engine cover off and find the coil packs in the center of the valve covers. The rears are located begind the back of the intake manifold, they cant really be seen well. Not an easy task for a beginner. Fronts are really easy, rears are not.
