All diesels have a certain amount of blowby, so if you are checking for blowby you are checking for excessive blowby not just checking for the fact the engine has blowby.
Just tested my car its 104000km 1999 Nissan Skyline, and it seems fine no puffing and or air comming out of the engine what so ever so im pretty happy.
This isn't an acurrate test for blow by on a turbo diesel because there is no boost being created, blow by will tend to show up as boost is created because of higher cylinder pressures, if you're experiencing blow by at idle you've got bigger problems
I have a 2001 Dodge Ram 2500 Turbo Diesel Cummins engine that has blown several Fuel Filter canister lids off , haven't been able to keep one on long enough for the engine to run very long. A minute or less .
this way to "check" blow by is if you suspect a dust out situation and is no way at all to check any kind of normal blowby that the cummins 5.9 will have. the 5.9 will have at rated load conditions up to 10 in-hg or 5 psi blow by and is in spec with such readings. the only way to check true blow by is with a water monometer or guage that reads inches merc/hg and a 302mm orifice.
You cannot check blow by in a 5.9 Diesel unless you block off the crankcase vent tube because the blow by is coming out of the tube instead of the oil fill cap.
If there is pressure in the crankcase it has to come out of the crankcase vent tube. That's what the tube is on the engine for, it has to vent somewhere.
when you do the test (oil cap OFF)....should you pinch/ seal off the PCV hose that directs blow from the top of the engine to the air intake tube? that way the blow by could only escape through the filler cap and you could check it .......?
+bigbore400 There is no pcv hose on this diesel engine. There is a draft tube that goes into the drip bottle. There is NOTHING that comes out on this engine.
@diesel world or any body else, in your experience execive blow by on this diesel engines cum mins , gm etc, if after leak down test you determined the piston /rings were the cause how do you proceed to the appropriate repair replacing only pistons and rings or do you always send to machine shop the block for cylinder walls honing? I am gas tech willing to move to diesel how ever I have notice diesel engines tend to have more blow by than gas. thanks
Hello I have a 99 Dodge Cummings turbo diesel with a 5.9 I'm replacing my turbo boost sensor right behind the fuel filter what size is the nut on the sensor and do I need a thin socket or a drive socket to take it off?
can you test this in the winter and if a tiny bit of smoke comes out or is it steam or smoke when I do the tea kettle test it stays on perfectly does not jump around at all but I tested it in the very cold weather and I don't know if this is steam or smoke
so I have a older car that doesn't burn oil . I am working through, some over hearing issue. now I don't own a compression test kit but I saw this and wanted to see how my engine faired well . I don't have smoke or oil blowing out but I have a lot of air coming out is that's good?
The cleaner the air the better. However on your car you might find a breather hose going from the rocker cover back to the intake which takes this overpressure crankcase air and pushes it back into the intake, the reason for alot of oil and carbon build up in turbo vehicles, especially diesels. If you have this hose and want to check for blowby tolerance simply loose the oil cap and either pinch or blank off the breather hose. If the cap dances around without shooting off from the pressure you're within limit.
Does this also apply for gasoline engines? I own a 2001 silverado with a 4.8 Litre v8 and i checked it cold and also at operating temperature and it had NO blow by what so ever.. is this bad that there is none at all? Currently 161k miles.
***** Thanks for your replay but the smoke is white (maybe blue but I can't tell). It takes quite a few extra turns to start it in the morning and after a mile or two when engine is hot it doesn't smoke at all. Glow plugs are blown. I also notticed that there is no coolant temperature on dashboard. Like there was no connection with temp sensor.
***** It smokes when is like +5deg celsius. It is direct injection common rail system. I suspect timing off but it is wishfull thinking;) It idles fine. Sounds very good. I think it has good compression but checking it would be very hard and expensive. Special tool required...Thanks
***** Replaced glow plugs - still smokes. Replaced temperature sensor and the same. It has hard time starting. I had a mechanic mith many years of experience to look at the smoke and it is blue and smells like oil for him... It smokes alot when car started in the morning and after 1-2miles it's ok but noticed some blue smoke as well but not that much... I guess that the engine is fucked;-(
When I first got my truck same exact dodge i cut the soda can thing off. That was a year ago. Now a mechanic told me i need a timing gasket. But i find all these different gaskets. I'm not sure which one i need. The leak is upper driver side of the engine. Can anyone tell me what to do to fix this? I don't wanna pay shop fees. All help is greatly appreciated. The soda can thing is at the bottom of my engine. Does anyone know how to fix this? I'm buying 2 gallons of oil every 3 days or so because it leaks that much oil. Thank you everyone
Yeah that's what it was i fixed it but it wasn't the gasket. Some how the flat metal cover had a twist in it. Weird because nothing touches the cover idk how it was bent. But i fixed it m had to go to Cummins to get the cover. . Thanks
It's a normal condition. The cooling fan tends to blow the oil all over the place making it more of a mess than it normally would be, due to the piss-poor location of the breather tube design for use in these trucks. The tube that you are talking about is the crankcase breather tube, and it's ventilating the engine from off the front of the timing cover. From the factory, that tube went into a small little plastic bottle, a little smaller than a soda can. If you read in your Owner's Manual (ya know, that book in the glove box that most people never read...) you will see that it tells you to empty the oil that accumulates in the bottle every so many miles or hours of run time (I don't know or remember the numbers.) What a messy pain in the ass... If the oil that "drools" from the breather tube bothers you, you can always play around with that bottle and do as you are supposed to do, per Chrysler. Personally, (and what most of us do) is I just get rid of that idiotic catch bottle and put a PVC tube extension into the hose, clamp it into the hose, and extended it down below the fan area a little bit, and then zip tie it to something down there that would hold it semi-rigid, so the tube won't flop around when hitting bumps and whatnot while you are driving. Let the thing drool. It hurts nothing. If the oil slop is a problem for you, I know guys that get all elaborate and devise a plumbing system to re-direct those gasses (and oil) from the breather, back and into the valve cover or the air intake. It's similar in concept to a regenerative system, like an EGR (Exhaust Gas Recovery) system that many modern vehicles have. Personally, I think that's a lot of extra work and pointless nonsense. Just don't worry about it. Every diesel I've ever owned has a breather or some type (they have to), and every diesel drools a little oil. Some just drool more than others. Kind of like dogs... or some people even - LOL! No worries, no cares. Now you know. Enjoy!
No, nature of the engine. The noise comes mostly from the valves under the valve covers from their springs. Best you can do for cabin noise is to add a liner to your fire wall, doors, and under the carpeting. Won't help if your windows are down and you're going through a drive through though. Awesome engine if you get the right make. Avoid engine block 53 (produced out of Brazil with thin walls on the cast iron block... known to easily crack) on the 24v and you are golden. If you want a 24v, best you can do is go for a 2002-2003... VERY solid motors.
First Step is Check It for In and Out Shaft Play. The Seals Can Start to Wear Without Shaft Play Developing, But the Only Way to Notice it at Early stages is From the Exhaust Smoking Blue, or You will Notice that Your Losing Oil and OIl Pressure. Under Worse Conditions, the Turbo Will Develop Shaft Play, and Oil Will Start to Leak Between where the Turbo and the Turbine Housing Meet Together. Under a Condition Like This It is Important to Replace or Rebuild the Turbo. If The Vehicle Continues to Be Driven Under a Condition Where The Turbo I leaking OIl, Then Often The Engine Is Next to Go Bad, Because of The Oil Pressure Being Lost Out the TurboCharger.
Blow by is when air passing the piston rings into the crankcase, do to worn out piston rings or cylinder bore. Often this can cause oil to leak passed the piston rings and into the cylinder and it will go out the exhaust.
@@turbolabamerica What this guy said is spot on. The reason is because you will develop a crack in the block... these are labeled block "53 (stamped into the side of the engine)." They come out of Brazil which used too thin of iron block... weights savings but not durable enough. Other than the VP44 (high pressure pump that goes out if lift pump starts failing) issue on these motors, they are VERY solid.
I'm having an issue with an 2002 four-wheel drive three quarter ton blowing that gasket off the side of the modem does it about every 8 to 9 months anybody ever dealt with that
It's been 3 years so I hope you figured out that the RAM doesn't have a modem at all. That would be really silly to have a corded phone jack on a truck.
I dont know anything about toytas other than the 22re is awesome. so i was taking a shot in the dark...I just have an old chevy truck and a vw golf daily driver
All diesels have a certain amount of blowby, so if you are checking for blowby you are checking for excessive blowby not just checking for the fact the engine has blowby.
The engine needs to be a full operating temperature for that test
Just tested my car its 104000km 1999 Nissan Skyline, and it seems fine no puffing and or air comming out of the engine what so ever so im pretty happy.

Now that's a healthy cummins

+Richard Bell No blow by comes out of the tube either.
If there is pressure in the crankcase it has to come out of the crankcase vent tube. That's what the tube is on the engine for, it has to vent somewhere.
+Richard Bell If there is n0 pressure in the crankcase ie no blowby, nothing comes out either place. Not every engine has blowby.
+dieselworld so should you pinch the PCV hose when you do the test?
These engines do not have a pcv hose like on a gas engine.
when you do the test (oil cap OFF)....should you pinch/ seal off the PCV hose that directs blow from the top of the engine to the air intake tube?

+bigbore400 There is no pcv hose on this diesel engine. There is a draft tube that goes into the drip bottle. There is NOTHING that comes out on this engine.
+dieselworld thanks.....on an engine with a pvc hose should you pinch it while doing a visual blow by test.
Pinch or blank it off momentarily. Has worked for me in the past. Also fitting a catch can has saved my turbo.
How much does a compression and leak down test cost?
Can you do a video on a 2001 dodge diesel on a map senor if it is bad or good one
@diesel world or any body else, in your experience execive blow by on this diesel engines cum mins , gm etc, if after leak down test you determined the piston /rings were the cause how do you proceed to the appropriate repair replacing only pistons and rings or do you always send to machine shop the block for cylinder walls honing?

Hello I have a 99 Dodge Cummings turbo diesel with a 5.9 I'm replacing my turbo boost sensor right behind the fuel filter what size is the nut on the sensor and do I need a thin socket or a drive socket to take it off?
Was the engine even warmed up or did you test a cold engine?
would that work on gas motor's to? or just Diesel motor's?
can you test this in the winter and if a tiny bit of smoke comes out or is it steam or smoke when I do the tea kettle test it stays on perfectly does not jump around at all but I tested it in the very cold weather and I don't know if this is steam or smoke
If it's w very cold start it might take a little bit for the engine to warm up and piston rings expand to normal operating temp.
How do i change the glow plugs in my 96 Diesel engine
Plug the front crank case vent and do that you’ll find it has blow by.
so I have a older car that doesn't burn oil . I am working through, some over hearing issue. now I don't own a compression test kit but I saw this and wanted to see how my engine faired well . I don't have smoke or oil blowing out but I have a lot of air coming out is that's good?

You going to fix that? seems like you have a strong engine otherise
does the engine have to pulled to repair blow-by?
how can one download the videos
I have a 96 avalon with the 1mz fe, does yours idle high when its cold?
Does this also apply for gasoline engines? I own a 2001 silverado with a 4.8 Litre v8 and i checked it cold and also at operating temperature and it had NO blow by what so ever.. is this bad that there is none at all? Currently 161k miles.

Sounds like the tappet cover gasket. Known to leak on these engines.

He needs to flip that cap upside down
Almost all 4 cylinder cars have blow bye... not really sure why but they do.
I should hope it don't have blowby it's dang near brand new
it basically means the engine is toast so yes
Yeah but you need to warming up that toy first and then I will believe you
Dont care if you believe me or not!
