Oil in my Airbox!!!

Ok I changed the PCV valve and cleaned all the intake and changed the airfilter. Well I though the valve was what was the issue. Well it is still leaking and i dont know what else it could be. I did a seafoam flush of the oil and the thottle intake as well just to mkae sure it was all clean. Now it has to be the motor is releasing to much gas at the top and it kincking oil out the PCV. ANyone ever had this problem. My motor is still under warranty because it was just rebuilt in Oct and only has 5,000 miles on the motor. But this shouldnt be doing this if this motor was just rebuilt.

 

Maybe a bad PCV valve?
I am assuming when the engine was rebuilt you didnt touch the top end... valve seal maybe?
Could have been a bad rebuild... getting a lot of blow by causing high pressure in the crankcase.

More than likely though its a bad PCV valve, they are cheap so I would try that first.

 

well the motor is under warranty so I am taking it back. I bought the new valvel from auto zone. it was brown in color just like the old one so I am think that old one came from autozone as well maybe I should go to toyota for one.

 

Check compression if more than 10lbs difference between cylinders you've got problems. Possible valves not seated properly or piston rings. Take it back to the rebuilder asap.

 

It would be the first time a new PCV valve was bad, try a new one from the local car shop or if you want a OEM one.

 

OK stupid question here how do i check the compression or do i have to take it somewhere to get done?

 

First, it's easy to check a PCV to make sure it's working. It has a ball in it that should rattle when you shake it. If you blow in one end, it should let air pass. If you blow in the other end, it should stop the flow of air.

Check your engine oil level just to make sure it doesnt have too much oil or something flukey.

Checking compression is not that difficult, but you have to have the gauge and fittings to do it. If you dont have much mechanical experience it would be best to have someone do it.
Take it back to the shop that rebuilt it and have them check everything. Tell them about it blowing oil.

 

Well I think that i could do it myself i just have never seen it done. I will look up online on what i need to do it. I know the PCV valve works because it did rattle. So I hope maybe it is the oil but i looked at it and didnt look like it had to much. I dont understand how it could be a compression issue if the motor was just worked. I called the company that did the motor and they want me to bring it back. But I am a little worried becuse i dont want them to mess the motor up any more than it is. My warranty runs out in October so i am sure they will try to give me the run around till then so I am going to have to study up on this and how these motors work.

 

If the piston rings didn't seal it will blow oil out the intake and exhaust.

They remove the spark plugs and install a guage to see how much compression the cylinders are making.

The test will show if it's the rings or the cylinder head.

You BETTER get that truck back to them asap.

Hopefully they will fix it; if they don't and they start screwing you around call your State's Attorney Generals office and open up a file (it's free) with them (don't tell the engine rebuilder you are doing this-leave it as a SURPRISE for them.) When the rebuilder gets a call from the Attorney Generals office he's going to soil his britches, trust me.

DON'T GET MAD, GET EVEN.

 

You said it would blow out the intake and exhaust. The only thing that comes out the exhaust is the puff of blue smoke that comes out when i first start the truck when its been sitting for a while and its cold. I will definitly get the rtuck back the guy that did it. I just want to make sure i know what he has to do to fix my stuff. I just bought this trucl last week and my wife is going to kill me if it breaks this soon. I kind of feel like an ass buying this thing. But the reputation of these trucks is just amazing they are the best!!

 

Dont beat yourself up! Let them check it out. If they are reputable, they will work to solve the problem.

 

I would think any oil that fets in the exhaust would burn up pretty quick (CAT)... hence the smoke.

 

well the smoke only last about a second so its not that bad yet but I am gooing to get this thing back to the shop ASAP.

 

White smoke means condensation in the exhaust. Normal.

Blue smoke means it's burning off oil. VERY BAD.

 

Dude, if your motor is under warranty, DONT TOUCH IT !!

Theres a damned good chance if you do anything it'll void or severly limit any issues they'll be willing to cover.. just my $.02

 

I dont plan on doing anything with it. And yeah it is blue smoke for a second on cold start. So I know its bad. its comming from the intake where the pcv valve is letting oil out. This sucks!!!These guys better freaken fix this thing or I am going to find the guy that sold me this thing and kick his ass.

 

You should not have this problem with a rebuilt engine. Do not let them talk you into anything but a repair.
Odds are, the rings are not sealing and causing lots of blowby. A leakdown test will tell you exactly what the problem is. Let them do it. If they refuse, get an independant test and make them pay when it fails.
Good luck!

 

Thanks for the support. I am going to bring it in. I will keep yall updated on what they are saying

 

Give the rebuilder the opportunity to fix it.

 

don't tell them you seafomed, that does cause pre-mature piston ring wear, i'm confused as to why you even did that if it was re-built.

Sound like rings didn't seat properly to begin with.
