Need an oil system schematic for a 1989 Isuzu Pickup

We're trying to find out what is causing an oil leak. We can see where it's dripping; however, don't know what's connected to the spot where the leak is. Thanks! Mary Alice

Sorry we do not have this type of diagrams. If you wish to see that you need a factory service manual, for a price you can download all the factory manuals and TSBs and service info at this site. It is a small fee to join.

Hello there, I have a 1989 GMC Sierra, 6cyl. After about 15 minutes idling after startup, truck bogs out on me and dies. Have replaced the fuel filter, gas lines, battery & alternator, new transmission...

The basics are fuel, timing and igntion. Seeing as you have changed the fuel filter and it runs for quite a while, you should take a look at the igntion system. The most common cause for your type porblem is the coil over-heating and shorting out. This could be caused by leaking plug wires or the coil itself is bad. Another less likely cause is the igntion module an-or the pickup coil.
With the approximate running time being the same, I'm betting the coil is the cause.
Good luck.
