Default Valve cover VCT sensor grommet leak

I recently replaced my valve covers with the Ford Racing “chrome” powder coat covers. Just this last week, I noticed a small oil leak which appears to be coming from the VCT sensor grommet on the driver’s side cam cover. These are the 07-08 style covers with the smaller grommets, not the larger easy to replace ones that came on the 05-06 style covers. Can anyone tell me if the 08 style grommets are available, and if so does the cover need to be removed for replacement?

I have an 07 and I noticed a similar leak from a rip in my driver's side VCT sensor seal after I removed the covers for powdercoating. Must've been too forceful when I used a socket to hammer-jam the seal back into the (uninstalled) cover after it came back from the powdercoat shop. I ordered a new seal from one of the discount online Ford parts suppliers. I pulled the torn seal out of the cover and used delicate taps around the outer portion of the new seal to seat into place while the cover was installed on the head. Been almost a year and a few thousand miles, with no problems so far.

Thank you for the information guys, did you have to pull the cover to perform the swap? If not, how did you remove the grommet?

The 05-06 ones look easy and even have tabs for removal, the 07-08 does not look quite that simple.

I wanted to powdercoat my valve covers for my '06 GT and a friend gave me a set off his '08 Bullitt so my car and I didn't suffer any down time, as he ordered the FRPP chrome ones and had them dealer installed I didn't know about the differences between the '05-'06's and '07 and up at the time and didn't find out until I started the install.
The oil seals were already removed when he gave them to me and upon getting them back from the powdercoater discovered whoever removed them must have driven them out with a screw driver as both sides were torn. I ordered new ones from a local Ford dealer, but had to call Ford performance to get the part number. The correct number is
7L1Z-6C535-AA and are about $6.00 each. I would be afraid to try and remove the old one and reinstall the new seal with the cover in place. One bad move and if you ruin the sensor I think you would be in big trouble. I did find that by applying a bit of engine oil on the seal and hole in the cover that the install went easily with a few taps of my hammer on the outer edges of the seal. Remove and replace for one cover should take around 90 minutes. At least it did for me.

Same thing happened to me after I removed my valve covers and put them back on. I really don't want to take them back off again, so I was wondering if I could try and put some silicone around the outside of the sensor to stop the oil?

You can get them at your local Ford dealers parts department, as the previous poster mentioned the P/N is number is 7L1Z-6C535-AA.

As far as removing the only thing I can think of is using a small screwdriver and try to carefully pry the old one out of the cover. You may also try cutting the seal near the sensor with a razor blade and use a curved pick to pry it up. (Had mine off when I used a large socket to knock mine out when the covers were off)

As far as installing the new ones on the car..... try lubing up the seal and the seat in the cover with a little grease, then some easy taps along the edge with a small hammer and a rag over the cover and the seal. Just go slow and easy and you should be fine.

There is no way you can do this with the covers on the car. They are too tight to get back in place without damaging the sensors themselves. The covers must come off.

There's a write up the describes the process here:

Not entirely true. PITA and should be done with the cam covers off the head? Yes. Impossible? No.

I swapped my torn and leaky grommet out without removing the cam cover. I fashioned a tight 1/2 inch U hook with a handle out of a metal clothes hanger. I punctured the soft rubber 'valley' of the grommet with the bend of hook and engaged the tip of the hook on the inside of the grommet rim. And pulled. I would not recommend this as the hook may slip off the rim and gouge the metal mating surface of the grommet hole. I got lucky and had no gouges.

Anyway when installing a new grommet it must either be slipped back over the sensor by pre-installing it in the cam cover off the head or you slip the grommet over the sensor by installing it in the cam cover already bolted to the head. So I don't think that you can avoid the 'too tight' issue.

I have finished the swap leaving the covers on. The drivers one came out very easy and the passenger side was a little harder. I did apply some sealant on the seal before installing. I will for it to setup before starting it up. A deep 1 1/16 socket works great to press the seal on.

Glad to hear it worked out!

Bringing this back to life for posterity:

I have an 06 with the tabs and found my passenger side leaking.

If you have an 05-06 with the tabs the part # is:

3L3Z-6C535-AA

I ordered the part # mentioned earlier and it definitely does not have tabs. Thankfully the one with tabs was in stock. It was $12 at the dealer.

UPDATE

Wow, what an easy removal and replace. Not a PITA at all!

See pics. Pretty self explanatory. But after I used a flat head screw driver and mallet to crush in the edges the seal literally popped out. I tried pulling it out by the tabs but ain't no way that is going to happen. The seal is actually metal covered by plastic/rubber. In the picture you can see I had already pulled off the neck of the seal that went around the sensor. That was the part that was leaking.

hi guys - did you ever try getting your grommets out without taking off your valve covers? I have the same issue and posted the below questions on another fourm.

Hey guys, I have this same issue. I didn't have this issue until I upgraded to the High Output Whipple SC (I had the regular SC non-intercooled before). Now I get oil leaking out of the driver side VCT grommet. I also have the Ford Racing chrome valve covers, which came with the grommets. I used the above part number and purchased two new grommets. The assumption is that the stock valve covers and the FR chrome covers use the same grommet, which looks to be the case.

My question is has anyone changed these out without removing the valve covers? It looks like I can leave the sensor in place, but just unplug the electrical wire, and then perhaps some how dig out the old grommet and some how pop the new one in, all without messing up my nice valve covers and without dropping either the old or new grommet down inside the valve cover. Please confirm.

As a side effect of the oil leaking from the VCT grommet, I am collecting oil in the adjacent spark plug area. It's not real clear how the oil is moving from the VCT grommet to the spark plug area, but it is. Has anyone had this side effect? At some point that area will fill up with oil and kill the plug. It also sometimes drips on my headers (stinks like crazy), which is how I found out about this problem in the first place.

I've also read that you can get leaks from the PVC port as well, under these same conditions. The solution is a oil catch can, which is better for your engine anyway. So I've orderd one of those too.

sorry, I just realized there was a page 2. I had posted and cannot edit my post yet ,so posting again.

I have a 2008 and the drivers side is leaking. I now read that davisr014 has been able to change these without removing the covers. I'd like to learn how you removed it. I read that the other guy used a hanger, but that sounds risky. Also, how did you get the new grommet in without damaging anything?

I have changed two of these now since my original post, and stand by my comment that the fit is too tight to safely replace these with the valve covers on the car. I had to use a rubber mallet to get the new seals fully seated.

I suppose you could try working with the right sized deep socket to work around the top of the sensor, but if you bang that sensor by accident it's going to cost you a heck of a lot more and you'll end up pulling the cover anyway.

Just my 2c cents...

Thanks Tim. While I would really like to avoid removing the cover, I do think that is the best choice. I'm sure I would screw things up trying to remove the old one, or banging in the new one. what a PITA.

Did you ever have oil pooling in by the spark plug on the drivers side?
