the oil blows out due to excessive crankcase pressure. more than likely a piston has a hole in it or it needs rings.

SOURCE: use 4.0 valve cover on 90 4.2l engine omit pcv valve use breather

not a good idea, engines rely on negative pressure(vacuum) for seals on crank and camshaft seals
also for emission standards, sorry

SOURCE: 1965 ford 352 engine blows oil out of breather.

I know the 65 didn't come with a 352, what is a 352? I thought it was a 351 windsor,? Anyway, did you rebuild the motor? There is a vent under neath the intake sheet metal that clogs up, It is held in the with a plate and rivets, you either have to remove the rivets or soak the whole thing in solvent. It will upset the car's pcv, a new pcv valve won't hurt, you don't need to be drilling holes, you might make it worse. Check all your vacuum lines. Make sure you have no leaks. Hope this helps.

I have a 1988 Scottsdale 305 4x4 manual trans.its leaking oil so bad smoke rolls from under the hood when I come to a stop.i know the exhaust it lose but could it be just that?


Yup, oil is leaking directly onto the exhaust and burning. Fix the oil leaks, normally always the valve cover gaskets, and replace the pcv valve(PCV positive crankcase ventilation valve). See can you put another PCV valve in the other valve cover and run it to the breather. The more of these lines you hook between the engine and breather, the less it will leak because vacuum is pulling all the pressure out of the engine block and crankcase so it won't push the oil out. My 383 small block has a bad front main seal, I hooked up another tube and it can't push oil out the seal. No more leaks. Hope you get her fixed soon Bro, you really look bad with all that smoke coming from your truck.

White smoke Audi 2.0 non turbo is this connected to excessive oil consumption is a 60k mile engine A4 reg 2001.


White smoke is usually coolant burning, but you say no loss of coolant, so must be oil burning. PCV is possible fault, especially since you say smoke is intermittent. Part itself should be cheap, less than $20. One your car I believe it is located in a pipe running from intake to valve cover.

My 4ja1 Isuzu pick up, fuego , has a smoke or mist coming out in dipstick. I check the breather and it has the same amount of smoke coming out. But every time I checked the level of oil by dip stick,


I take it that this is a diesel engine. The oil you should be using is diesel oil 20w-40 or 50 next there is blowby from the combustion process that is heating the oil in the sump and it is fuming of. If the engine is running well it is not a great problem
If when doing an oil change the oil is thick and heavy and doesn't like to run out then it is a problem as the paraffins in the oil are burning and reducing the oil to tar.and this means engine rebuild.
If it is a petrol engine then you can use diesel oil in it as the only difference is the cleansing additive in the diesel oil. It helps keep a petrol engine clean inside

That is not supposed to happen. Oil being sucked into the intake manifold. Ever. You have something hooked up wrong or not even hooked up. Be sure the line from the PCV in the valve cover is hooked to the breather case, NOT vacuum fitting on the carb. Run a full breather also, nothing missing.

Hi. I have a 2006 Toyota Hilux with a 3.0 litre D4D diesel engine. It blows out blue oil smoke for about five seconds on startup. If I perk the car on an upward facing smoke the problem is worse. If I park...


Hi , couple of questions,
1. is it using engine oil?
2. What type of diesel fuel do you burn ?(cheap/premium)
3. Have you ever used fuel additives ?
4. Does the smoke go away after warm up or still there when you put car under load / accelerate hard?

Simple thing first with the engine ticking over lift bonnet/hood and remove the dipstick, have someone lightly rev the engine LIGHTY if you see oil traveling up the dipstick spout , this is a sign of the crankcase pressurising , their is a crankcase breather filter which are obtain overlooked during servicing which can cause e
If you are not burning oil , look for the egr valve it will be coming off the air intake and insure it is clean and operational( this is an emission saving device fitted to diesels which lets the engine re -burn it exhaust gases) it can get clogged with oily residue from the diesel fuel and in fact can be like a tar consistency this clogs/ not functioning correctly can cause power loss and oil deposits making their way into the exhaust system and stops valves seating correctly . On positive it is easy to work at and clean with brake cleaner, then dry and lightly oil to free up then wipe clean.

also worth while and to ensure work on egr was worth while and lasts remove the air intake ducts as these too will be clogged it builds up over time and can reduce the air duct flow by50% this is not cleaned during ordinary servicing! clean with boiling water and washing up liquid sounds strange but worked best for me! Let sit to work using baby bottle /pipe cleaners when clean ensure it is dry completely before refitting I found blowing out with compressor was worth while as you do not want and loose dirt inside as I will make its way through.

final thought which has been very beneficial for me, when carried out the above use only premium fuel( cheaper fuel now is mixed with bio diesel and leaves bad engine deposits ) use diesel fuel additive I have found millers Eco max 4 excellent, double dose first time drive hard in 3rd for a few miles to work its way though you will notice smoke for the first couple of used this is contamination working through system. Let me know how you get on and good luck.

bad ring. make sure your pcv valve and breather tube are working. lack of oil changes can cause ring not to seat. flush engine with gm top engine cleaner. may help release rings. run engine about 25 miles then change oil,

Make sure the hose connected to the PCV valve is connected at both ends and has vacuum. It is better to replace rather than clean a PCV valve as they are inexpensive. It sounds like your engine is building up internal crankcase pressure so a new PCV valve would be a good place to start. The "egg" smell could be that the catalytic converter/s are going bad and need replaced.

Hi i have a 2000 estima van, 3000cc just been serviced and is blowing alot of blue smoke especially under load? only done 92000 kms.


there are very small oil galleries in that engine and the varnish will build up and restrict the flow of oil and it will leak past the valve guides.
do a compression test,and if it is good,the oil is not burning from the rings.,but from the valve guides.the seals need to be changed.
