screw up big time

[1iwilly]

well murphy law hit shit does happens. i was doing a air pressure test on the intake to check for leaks. using soapy spray bottle i disconnected the hose that goes to the dip stick coming from the CCV and plug the hose up as to not put air in the oil pan using a 12 volt tire pump well i forgot to shut it off and after 3 minutes i heard a pop.like around the intake.i paid it no mind cause i though i saw air bubbles by disa valve was false.well then i notice all my engine oil on the ground . that seems to come out of the oil tube that was open after i clean up the mess got new oil put it in truck is smoking out the tail pipe still running smooth. i turn it off the next day i took valve cover off found no issues. spark plugs 5&6 had a slight coating of oil like when you flood the engine. any way is there a possibility that oil was push into the intake then to those 2 cylinders.?? i'm still curious what the pop was. thanks all this been in a hurry as it was getting dark and i didn't feel like waiting for next day. i know dumb ass now paying the price

oil separator was my first thought as well but I really can't explain why other than that i know a faulty oil separator can cause the engine to consume oil.

Thanks guys that's what I'm thinking too.
Should I just let it run to burn out the oil in the cylinders 5&6
The sparkplug just had a residue like when the engine gets flooded.
I've crank the engine over a few times and no oil what so ever has come out the 2 cylinders
Will try to spray carb cleaner in cylinder
Then push it out by cranking it over blow some air into it to make sure it is dry as to net have an explosion.LOL thanks again I was afraid I might of had to take the head off.

Actually I was using the hose from the valve cover that goes into the ccv.

QUOTE=trader4;1007233]From the wording, it's not clear where exactly you had the air pressure connected to, but you obviously pressurized the crankcase because you pushed oil out of the car. For oil to get immediately into the intake, the only way I could see that happening would be if the intake was *not* pressurized, but since that seemed to be your focus of what you were trying to pressurize, that doesn't seem to likely. The other scenario that would get oil into the intake would be for your pressurization to blow up the oil separator? Maybe that's the pop you heard. It has some kind of diaphragm in there and if you blow it out, then start the car, I think the intake could then suck in the crancase oil, ie the dreaded oil hydrolock problem.[/QUOTE]

i just change the whole CCV in june 2014 all new hoses $128.00 for everything i'm puttin the valve cover back on and plugs coils to test it again
just to make sure no more oil in chamber then tomorrow i'll look more deeper into the oil separator. thanks for the replies

OK, you mean you disconnected the hose from the top of the valve cover and connected pressurized air to that hose. It seems kind of an odd way to try to pressurize the intake system. That hose goes to the oil separator. I have no idea what exactly is inside, how much pressure it can take, but would expect that it's not designed for much pressure. All it's expecting on that hose is the typical pressure from the crankcase when the car is running. And as I said, as I understand it, it does have some kind of diaphragm in there. I would suspect you blew it out.

I would proceed on the basis that the oil separator needs to be replaced. Depending on how old it is, maybe it was due anyway. And I would not run the car anymore until that is done. You could still have a direct connection from the sump to the intake via a kaput oil separator. You need a new oil separator and the 4 associated hoses. When I did
mine, I wound up removing the distribution plenum that sends the recycled gases to the six spots on the intake manifold. You may not need to do that, but it makes getting at the hose connections easier.
And if you do, there are 6 little o-rings there that should probably be replaced. I didn't have them, so I reused the existing ones. You can find them online for ~$2 each, you need 6.[/QUOTE]

thanks well i clean most of the oil residue in the cylinder crank it over a few times until no more carb cleaner came out blew some air in the cylinder crank it over a few more times bone dry put it back together ran it for 20.minutes until all the smoke was gone then test drove it. it is all good no more problem i tested the oil separator tested good been i still had the old one laying around took it apart to see what was involved it's a no brainer. once again thanks to your replies made my job easier when everybody agreed on the CCV
what would be a good oil stop leak to use with synthetic oil i'm not ready to tackle the very small rear main seal yet.

You already have oil showing up in a couple cylinders. These engines have been known to fail that way on their own, with the oil separator failing in a way that leaves sump connected to intake, whereupon the engine sucks in the sump oil, locking the engine. The results aren't good. How lucky do you feel?
