HELP getting gas in the oil

I had NAPA do a valve job on my 97 Jeep wrangler 2.5 . It now gets gas in the oil. I thought maybe I had goofed putting the head gasket back on, so I took it back apart and put a new head gasket on. It still gets gas in the oil. It never did that before the valve job. I have pulled the fuel rail off and check for leaking injectors. No injectors leaked or leaked down. I am at a loss for the cause and wonder if anyone has ever ran inot this before. Thanks

If you have an engine mounted fuel pump, it's possible you have a break in the diaphram which is allowing the fuel from the top of the pump into the crankcase. The only other place would be the intake system. How are the plugs? If you were running very rich some fuel could be running down the cylinder walls past the rings into the crankcase(not likely).
Let us know what you find.94

Well its a 97 TJ 2.5 It never did it until after I had NAPA do a valve job and deck the head just a bit. I dont know if NAPA screwed up the head or what. I am at a loss,,,CAn I get 2500.00 for it,,Its has 31's a winch and besides the gas in the oil, its in great shape, its has a new Best Top Sail cloth top. and a kicken stereo. Thanks

how many miles are on it? it could be that the rings are a little worn, and the valve job, and head decking may have raised the compression enough to force some fuel past the rings on the compression stroke
