fuel in oil again

I tried this before and got no responses so I'll try again. I have fuel in my oil after replacing the FPR and confirming it is not dysfunctional out of the box. I've also had the injectors cleaned and presure tested. After this the fuel is still contaminated. Could it be fuel blow by from the previous round of fuel in oil washing gas off the cyl. walls? I'm stumped and don't know what else to check. The car is parked until I can figure this out. Help from anybody would be appreciated. I know someone is going to say check the FPR again but I have confirmed the vacumn side is clean and dry and devoid of fuel. HELP!

Have you run any type of fuel system or engine flush through it lately. If this is the case it could just take a while to work it way out. If this it not case you might check your O2 sensor because your engine could be running very rich.
You might also try typing gas in oil in the search box at the bottom of the page. I tried and it came up with several pages of previous posts. Good luck and let us know what the problem was.

thanks. Yea this is a stumper. I've assumed the rich running only to be presented with tan, non sooty plugs. I replaced the O2 sensor just in case. I've recently switched to redline synthetic prior to this problem and had added an oil additive from IPD. The synthetic ran for about 50 miles before I discovered the fuel in oil. I drained it and filled with a non synthetic till I can figure this out. I'm also hoping when I get back from the holiays that the oil level is where I left it and perhaps the old contaminated oil wasn't all removed since I didn't drain the turbo lines. Most of the posts I've search center on the FPR and leaking injectors. I'm hoping for the best when I get back and check it. In the mean time thanks for responding! I was despairing that only Q&A about tail lights and seat heaters elicited responses!
