All About Valves

Archive for the ‘Oil Valves’ Category

A leaky engine is one of the most common and most irritating issues that tend to pop up for drivers. An oil leak can happen at any time regardless of things like weather or the age of the vehicle. Checking for oil leaks is something that you should do regularly, even if you have no reason to believe there may be one. Even a small leak can go unnoticed for a long time until it grows into something much more serious. It’s simply best to be safe and eliminate that possibility.

An oil leak is usually found under the front half of the car, where the engine sits. A bad leak will be noticeable just by getting down on the ground and looking under. For something smaller, you may need to get up close. Oil is pretty easy to identify. It is very thick and either brown or black. It has a certain smell that is not quite like other vehicle fluids. You will have a good idea if it’s an oil leak based on sight and smell.

An oil leak usually comes from the Valves or the oil pan. Any number of things can be the cause of an oil leak. It can happen even on newer cars without warning. Oil is essential to your engine’s ability to run smoothly and it can become an expensive problem if not dealt with right away. New cars should be covered by warranty for a random oil leak.

Once you are certain that you have an oil leak, check the dipstick. Check it like you would any other time and take note of how empty it is. This will give you an indication of how fast the oil is leaking and how bad your problem really is. A very slow leak still needs to be dealt with but it gives you more time to call your mechanic without severe worry. If you have a massive leak, call them and tell them. It may have to be towed in the worst case scenario.

If you can’t see where the leak is coming from you may have to take some further measures to pinpoint it. Never just assume that you know the exact spot and start trying to fix it. You can waste time and money this way. You need to know where the leak really is. This means getting a little down and dirty but it will be worth it when you can get to the root of the problem.

Try cleaning the engine with a good, safe engine cleaner. Washing away other dirt and grime might make it easier to see where the oil is coming out. If you still can’t find the leak, drive the car up on to safe lifts, like the ones used by mechanics or for at home oil changes. A jack is ok for lifting but you should never get under a car only secured by a jack. Safety should always come first. If you can’t get the car safely lifted, have a mechanic do it. Check for oil leaks as soon as you suspect them to avoid potential vehicle failure.

Why does one of my Valves have oil? Will chose best answer pics

on the upper right valve

If there was oil on top of the piston, then you probably have an oil leak in the cylinder head and may need a new one. Id get a valve spring compressor/remover and take out the valve and look inside with a flash light and see if you can find it yourself.

My oil pressure bottoms out at idle…..maybe stays at 5. When driving or reving the engine to 2000 RPM it goes up to about 20. I think that this is indicating a Pressure Valve that is stuck in the open position, however I can’t find any reference to a pressure valve in any Chiltons or Hanes Manuals. Any graphic help would be appreciated.

be sure you actually have oil in the engine!!! look for a oil pressure sender (not valve). I could be wrong, but look around the oil filter for a 1 wire sender. check the oil level first, please!

You have worn valve seal and valve guides. Send the head for a valve job. They will also check for cracks and spring pressure and replace your guides and seals at the same time.

good luck…..

I had received the code P2647 and they said that I would need to replace this switch. I can not find a diagram in the Haynes Repair Manual. Thanks for your help

On the back of the engine block on the passenger side. Standing on next to the front passenger tire with the hood open, you’ll see it fairly easily above the exhaust manifold on the back of the block. You’ll see the wires running to it.

There is a screen on it that can become clogged, you might try removing it and cleaning it.

I have a 2001 olds Alero 2.4 twin. Front wheel drive ( if that matters).
My mother in law purchased it from an auction with major front end damage from a front end collision. I now own it. It stopped running on me this weekend and I thought it was out of gas but after putting in 2 gallons that was not the problem. A neighbor of mine took a look at it because he works for a BMW dealer doing service work. I am not fluent in mechanical lingo but I have a cover bolted on top of my valves and he took it off and when he did the bolts were pretty greased up with engine oil. After removing the cover the valve canyon ( i don;t know what else to call it) had a pretty steady cover of oil all over it.It wasn’t black oil it was actually quite clean I guess is the way to say it. My neighbor said there was oil in the spark plugs too. I just want to know with the valves leaking is it my driving that did it or could it be because of the front end impact. I have already had to repair the rack and pinion because the collision just wondering if this is possible too.
okay heres is the whole story. I assumed i had ran out of gas, filled it up with five bucks gas and it doesn’t start. My neighbor couldn’t hear the fuel pump come on when I just turned to car to "on". I did try and try and try to start the car over and over again just cranking and getting nowhere. My dad said that the oil pump would be working and pumping oil through the valves and plugs but would have nowhere to go because the fuel pump was not kicking on to turn the engine over. So there would be oil under the valve cover. So I assume it is just the fuel pump now? Could that be? Or does that sound right?

regina your car doesn’t sound like it is old enough to have leaky Valves could it be possible you have a leaky valve cover and it spilled onto the spark plugs you may want to ask…..the collision would not have caused the leak …….there is a rubber seal inside the valve spring that keeps the oil from leaking down into the cylinder it is shaped like a up-sidedown cup it sits over the valve shaft inside the valve spring i hope this info has helped please copy it you will be better armed at the repair shop

engine oil is not getting to Valves in No. 1. Whats going onnnn??? Oil press is 50kpa @idle. Am using GTX oil , Can anyone suggest anything???? Thanks soooo much

dirt or a restriction in the oil passage to that area of the head…if u can disassemble blow air into passage or try some rislone in the engine oil to see if u can dissolve the plugged area

i know # 1&2 from the timing chain but what about 3&4?
cylinders 1,2&3 are getting tons of oil from the wash from the timing chain.
where does the oil come out of the head to lube the valve train?

The oil pump pushes oil up into the head to lubricate the Valves by means of oil a passages. The timing chain does not lubricate the valves.

i got a trombone and was wondering what type to get

Valve oil and slide oil are relatively the same because they’re both called "oil". Both are petroleum based (unless it is synthetic oil) and both are designed to pretty much work interchangeably.

Slide oil tends to be thicker because the space between the outer slide and inner slide is greater then the space between the valve casing and the valve itself.

Products such as "Slide-o-Mix" or "Yamaha Trombone Slide Oil" are not actually oil. They are liquid versions of slide cream. Those types of "oils" have a faded white look to is, looks like watered-down glue. Regular oil is clear unless it is coloured.

can i change oil valve seals on an avensis year 01 and its a 1.6 petrol without taking off the head? i think there is a special tool for this?
i have heard that the valve seals go hard and would be worth a chance in replacing them to try it. if the piston is brought up to top dead center there is a tool to release the collets without taking off the head. save me geting a new head gasget and extra work.
i have heard that the valve seals go hard in some vvti engines. and if the piston is prought up to TDC that the collets can be released using a special tool. it would save me geting a new head gasget and save alot of extra work.

its impossible to do this job in situ the head has to come off and not a job for the novice,special tools and experience is essential
