I have a 4g37 and am changing the timing belt and my Chilton says there is a plug on the rear side of the block that I need to locate (I wont go into details) and they give this image:

(IMG:http://i173.photobucket.com/albums/w72/lukeblood/Oil_pulley_check.jpg)

Is this the plug I am looking for?
It is the only one I could find...

This view gives a better idea as to where it is

The sooner I can get help the better!
Thanks

According to Chilton:

"There is a possibility to align all timing marks and have the oil pump sprocket and silent shaft out of time, causing an engine vibration during operation. If the following step is not followed exactly, there is a 50 percent chance that the silent shaft alignment will be 180 degrees off.

12. Before installing the timing belt, ensure that the left side (rear) silent shaft (oil pump sprocket) is in the correct position as follows:
a. Remove the plug from the rear side of the block and insert a tool with shaft diameter of 0.31 in. (8mm) into the hole.
b. With the timing marks still aligned, the shaft of the tool must be able to go in at least 2 1/2 in. If the tool can only go in about 1 in., the shaft is not in the correct orientation and will cause a vibration during engine operation. Remove the tool fromt he hole and turn the oil pump sprocket 1 complete revolution. Realign the timing marks and insert the tool. The shaft of the tool must go in at least 2 1/3 in.
c. Recheck and align the timing mark.
d. Leave the tool in place to hold the silent shaft while continuing."

If you didn't bother with it, maybe I will just continue....
But you probably used up the good 50% chance and now I will get stuck with the vibration haha

it should be the right one, the hump in the block that the plug sits on is there for a balance shaft. But i'm not very familiar with the 1.8L

I replaced the timing belt on my old 94 1.8L too, I never messed with it, I guess I'm 50% lucky.
