cracked my placstic valve cover

i noticed over time my oil level was getting low. i park my yj in the garage and there is no signs of a leak on the ground. but on my valve cover there's always a mess (like that when i got the jeep). well tonight i decided to try and tighten up the valve cover (i read in some other threads that might help resolve my problem).

well, i cracked in on the corner. is it ok to drive like this for a short time until a replacement comes in? i don't have to drive it, it's my weekend cruiser, but i need to get it inspected before the end of the month. of should i just leave it parked, replace the cover and then inspect it?

where you cracked the corner does show any signs of leaking. Hows your oil level? If it is not leaking then drive it I would if it shows no more leaking but keep an I on your oil level

it just happened about 2 hrs ago. i've been searching the google for info on this situation. most people with various different vehicles are saying they are drivable with the cracked valve cover and to watch the oil level. i will be ordering a new cover soon, but my guess is it will take about a week to get in.

like I said if it is not leaking more oil then it should be fine take it around the block a few time while running hot and with good flow and check for leaks again

i've driven it around town and then checked it, and i didnt see any more of a mess than before, so that's good. but now i can't find a new valve cover. everyone i see that's for 2.5l yj says not for fuel injected engines. if that's the case, where can i get a replacement valve cover that will work. all the ones i've seen look like mine but all the descrptions say they won't work.

Ordered a new cover. Should I clean and degrease the mess now with the old cover still on or wait until after I put the new cover on?

I have a 4.0. When I bought mine, the PCV system was not intact and must not have been so for quite some time. I bought new PCV ports, hoses and gaskets, then took off old valve cover............ And was encountered by what looked like a compost pile of carbonized oil. In fact, it was so full of hard oil that it maintained the look of the inside of the valve cover even after I removed said cover.

I chipped away as much carbon as I could, trying to keep any from going down valves. Then I emptied te oil from the crank case and filled it up to the brim with diesel fuel, letting it sit for about 24 hours.

Next day, I emptied the diesel fuel out and had ordered a brand new valve cover because the PCV ports were so clogged with carbon, it was trashed.

Installed new cover, ran engine for a few minutes, then changed oil again. Now she runs like a gem...

Just my experience.

got my replacement valve cover today (plastic) and it came with a pre-installed rubber type gasket. is it sufficient? i ordered it over the phone, so i didn't realize it came with this. i also ordered a gasket. can i use the installed gasket and return the one i ordered? anyone have any experience with this please weigh in. thanks

Ok the rubber gaskets are best, but what about the pre installed gasket? Do I tear it out
