Your ECU monitors and reports any activity going on in your car. With the help of the Electronic Control Unit (ECU), with which modern vehicles are equipped, you can notice any unusual activity going on in your vehicle via the check engine light. Here is a more detailed list of the signs of a bad or failing oil control valve to look out for: 1. You may also notice issues with the performance, like rough idle, rough acceleration, increased fuel consumption, or low engine power. The most common symptom of a bad VVT solenoid or oil control valve is a check engine light on your dashboard. On my son's truck, it started leaking pretty quickly.Conclusion Symptoms Of A Bad Oil Control Valve (VVT Solenoid) You are absolutely certain that it's the head gasket? Have you degreased/ pressure washed the area, and checked again? The only Romeo 5.4s are the aluminum versions found in the first Ford GTs, and the S197 GT350s. Covered everything underneath, the tailgate and my trailer with oil.ĪLL truck 5.4s are Windsors. I did a 140 mile trip with the truck a few weeks ago and went through 2 quarts of oil. I was hoping to get away with not doing it but it's to the point I have to. romeo or windsor) but it's hemorrhaging oil from the passenger side head gasket. *Isn't it coincidental that the metal shavings always fell in the same spot on the engines for years? Why did it never happen on the other head? If you ask me, the machine tooling was starting to get worn out at the Romeo factory, and needed better/ more frequent calibration.Įvery now and then, an engine would leak, and Ford made up the excuse that it was "metal shavings"* to keep from paying for new machinery. ![]() When I removed the head, there was no evidence of any metal shavings, or whatever they were claiming the problem was. Just so y'all know, my son's '02 F150 with a Romeo engine had a head gasket oil leak, and it was outside of that date. While there is a TSB for 98-00 Romeo manufactured 4.6s and oil leaking from head gasket (due to metal chips in one corner of the head), it was for a specific timeframe on machining, and doesn't extend to 2009. If you have an oil cooler, look at the hose ends.as others have said, oil has a way of ending up a long way from the leak source. The 03+ gaskets were redesigned to help eliminate that leak source.Īnd, just so you know, I don't believe I've ever had a problem with head gaskets leaking oil. Also, what year engine? The valve cover grommets were also a leak source on a lot of the 96-02 engines I've worked on. It’s a huge pain, but I agree with SoCal Sam, a thorough clean up, then close monitoring will show you where it’s from, if you even still have one. (You likely saw the big factory gloop Ford puts there when they screw the engine together.) See photo below. There is a tiny seam where the head meets the block by the timing cover, and that area requires a small amount of high temp RTV. ![]() When you did the valve cover, you used high temp RTV on the block seam at the front of the block correct? You mentioned above you replaced the valve cover gasket, it’s a common leak area, that could be residual from your repair. If it’s getting blown around, could be from anywhere.
