oil in throttle body
 

Anyone have a supercharged 5.4 have any problems with oil. like always having to add oil and oil all over inside throttle body?:mad:

yes, i have a 2001 lightning that does the same. i dont have all the answers on it but apparently its a design flaw with the p.c.v.system causing this under boost conditions. i saw a kit that allegedly rectifies this on e-bay under parts and explains the situation somewhat!!! im reluctant to pop for it though and sort of looked at it as a sales pitch without any real proof it works behind it. good luck.

oil in throttle body
 

I just had a frind of mine (hes a mechanic ) take my intercooler out and clean it. What a oil coated nightmare oil coated everything he even said he couldnt beleive what a bad design by ford. I also installed a oil seperator from razors edge and after only 30 miles I had about a teaspoon of oil in the bottom. For $50.00 I think its a good investment. :-X22

sounds like a great idea harley. =)

harley, where exactly did you place the oil seperator?? between pcv valve and hose to intake i assume?? also where is razors edge??. thanks.

Oil separator
 

03Harley, does Razors Edge have a website? I'd like to get one of these for my 03 HD.

From what I know the problem is caused by going into boost then releasing the throttle quickly, causing the intake to suck oil thru the pcv system. You can purchase a oil seperator system from several sources. Go to NHTOC.com and do a search for this same topic, you will a truck load of info!

Oh...and I dont believe its as easy as adding valve cover breathers...unless you have your pcm reprogrammed Im pretty sure it will set a code.

Heres some links to vendors that sell the kit...

breathers
 

I wrote an email to Lightning Enterprise regarding breathers and this is the reply I got:

Personally I have tried it both ways...only no one seems to ever know what
figures to use when allowing for the corrected air entering the open
breather and into the air / fuel ratio.
I have dyno tested with the breather and found that without correcting for
the supposed added air that enters the equation that there is a small amount
of leaning out through mid range RPM but that it equalizes by 4500 - 5000
and doesn't seem to cause detionation during the lean period what so ever...

No I would not reprogram my PCM...besides what figures would you use anyway
as I have no knowledge of any being comprised...


So what are your thoughts on this?

so what do you think?
