Oil Leak...Valve cover Gasket?

So Im deployed right now and the wife, bless her little heart, decided to take my truck in for an oil change. Well apparently when the guy was filling it up with oil, there was a "significant" leak coming from behind the valve cover (passenger side obviously). I noticed a small leak before I left, dripping down on the up-pipes behind the passenger side valve cover. I havent had the truck long but the guy I bought it off had just done injectors and glow plugs so im thinking he cracked the cover or didnt get the gasket seated. Truck runs 110%, no sputters or abnormal smoking. What do yall think?

First off, Thank you for your service!

I would tighten the valve cover bolts, it's probably not seated well. If it continues to leak change the gasket but get a complete with wiring harness one from Napa, runs around $80.00 bucks, I would doubt it's a cracked cover, they are durable unless the other person twisted it which still would be hard to do.

Pick a good friend to do it for you since your not home, Ford will take your money and give you back a large smile.

Give it a good engine cleaning b4, removing the A/C compressor helps, loosen the serpentine belt ( check for cracks or unusual wear or replace it and keep the one you have as a spare) remove the four bolts and just set it aside, this will allow easier access to the valve covers, Watch out for the battery when setting aside, I placed a small piece of wood under it . Ask the person you purchased this from if he changed the glow plugs, this would be a good time to do it while you have it apart.

Thanks for the advice, the guy I purchased the truck from said that he did both the injectors and glow plugs. Is there any way to really tell if he did? This is my second 7.3 but I never had to do anything but replace the transmisison on my last one (01 dually with 280K)? And I always keep the old belts, the make a good oil filter wrench on these trucks when used with some vice grips

i had more leaks than i could count on the 97 when i had it. that was the biggest problem i had with that truck was new oil leaks developing left, and right! valve covers, hpop lines, engine seals. never leaked it too low so i guess i was good. my 2000 hasn't had those problems yet though the 97 had much higher mileage than this one when it started to get all the leaks. it did get a few before 165k though.

oh, and stay safe out there friend!
