I found some fuel in my oil. How involved is changing the fuel injectors?

Check your fuel lift pump on the stbd side of the engine. Most likely the fuel is coming from a ruptured diaphragm.

thnaks I'll look at it. I replaced the pump 2 years ago

I took my injectors out last year or so and had them re-calibrated, the engine sounds and starts so much better. It was not hard at all to remove them and reinstall them. I do recommend taking a picture first for reference.

If I purchase new injectors do these need to be tested and calibrated or are they good to go as purchased. I see them listed for $53 at Torreson. I figure by the time I ship old ones back and forth and pay for calibration, I'll be close to 100 bucks anyway. Does this seem correct? Thanks

They should be good to use out of the box. The pop testing and shimming of used injectors is to get equal spray. If you put two new injectors in you should be fine. Make sure you also get new mica insulator disks that go between the injector nozzle and the head when you put in the new injectors.
