If theengine coolantis warm.

 

when the engine warms up its about 600-700 idle...good or bad...

also when i take off the oil cap and smell it i smell gas also...is this typical or no

also on the passenger side of the engine..where my fuel injectors go right by the valve cover iam gettin alot of build up in tht vally...on the driver side it's so build up and gunk but the left side is way worse....and i beleave it's gettin worse...not just build up but now iam starting to see liquid and gunk...is this just typical 80.000mile ware and tare or iam thinkin i have a leak..

and if i did have a oil leak would'nt my oil gage go down....
