What is the easiest fix for an oil leak on my passenger side of my taco 2.7L motor? I have a steady drip covering most of the right side of my motor. What is the most common oil leak? I have a 2000 Tacoma Prerunner. Also what is the best fix for a sticky EGR? I keep throwing a 401 code. I have researched this topic and found that if the EGR is removed that this would create a lean condition (If I remember correctly) and heat the motor up a bit while cruising at highway speeds. I would actually lose power if the EGR is removed.
Thanks

I sprayed power tune into my egr valve on an older toyota and it cleared it out and freed it up.

I would guess it's probably your valve cover leaking.

power tune is sold under what brand name? found at Advance? thanks

It's actually a marine product, but it worked for me:

thanks- I will let everyone know my results! Anyone else out there have any more ideas about the oil leak? Not too sure it is coming from my valve cover.
thanks

Leaking valve cover gaskets are pretty common.

should i purchase a new gasket from toyota or go to my local parts store?
thanks

some times just tightening them to specified tightness is good enough but others yes new gaskets!

these trucks are notorious for loosening those bolts ans a simple tightening is necessary so try this then move on..
just be sure not to over tighten and bend the valve covers either way!!!
