In this video, I cover procedures on conducting a relative cylinder compression test for a DD13. Whenever high crankcase pressure is suspected this test can confirm if compression is being lost. This test is the same for DD13, DD15, and DD16. High crankcase pressure can be caused by multiple items, such as worn-out cylinder liner, postin ring, loose injector hold-down bolt, valve, or jakes out of adjustment. If you are troubleshooting an engine with high crankcase pressure than this test is good to conduct to ensure all cylinders are working correctly. A DD13/DD15/DD16 with high crankcase pressure can cause oil leaks and low power.
Check out my other video on the DD platform. Common issues with the DD15 are a great video if you have just purchased or going to purchase a DD15.

Hello there sir. Thank you first of all for your very helpful videos. Question I have a 2012 DD15, I just noticed that I’ve been getting quite a bit of crankcase pressure through the oil cap(hopefully I’m explaining myself). Engine has a little over 1 million miles, now even though I see the pressure my coolant still perfect without any signs of oil. Can you kinda point me to what it could be? Would a cracked liner give me oil in the coolant?? Thank you sir.

[@nathanielpoole2548]

Good morning. I have a 2011 Columbia dd15. Driving down the interstate at about 70mph. Loss power looked on passenger side and saw oil from crankcase breather all the way back to the back of the truck. No warning. Truck would not start. Starter wet with oil. Able to bump it over but not enough battery. What would cause engine to shut down, no alarm or warning engine temperature was high too

I have dd15 2014 freightliner Cascadia I have a tick in the motor you hear when cold and oil pressure is 100 psi when starting and then idles down to about 60-65 psi and when driving it comes and goes but when it comes it feels like it wants to cut off do have any idea of what it could be

I’m having nightmare with my truck. Took it to shop more than 5 times with same issues. It’s 2017 cascadia dd13 402k miles. Truck ain’t got power and getting 6.13 - 6.33mpg . My load will be always less than 29k. And top speed I go is 67mph. Did tune up, pressure test and everything it needs. I’m still having power issue and burning lot of fuel

@@TATEXPRESSINC good afternoon I have a Cascadia with a DD15 with 800,000 miles the engine was leaking oil through the Crankcase Filter but a lot .. I replaced the filter and kept doing it but only on the climbs and very heavy when the trailer is empty it does not drop anything oil ... a workshop already removed the oil pan and checked the piston liners and you can't see a single scratch the compression test that you do in this video they did it to me and it's fine ... they want to change the turbo say that it may be that it is putting pressure to the engine by the oil return ... the engine does not show any symptoms of wear does not lose strength does not have faults does not burn any oil between oil changes ... you think that the turbo can be the cause? any recommendation I would appreciate thank you

[@TATEXPRESSINC]

Alex, be sure you are selecting relative compression test. Its not automatic compression test. Yes, running at temp will give you better readings.

[@nomad6199]

@@TATEXPRESSINC Hi, figured it out. Thank You Something with either software or the filter's drivers, reinstalled them and it worked like a charm. 53% compression though in cylinder 3 Seems to me that it will need an overhaul. Some white smoke and excessive oil out of crankcase breather.

[@TATEXPRESSINC]

Be sure to run through trouble shooting before condemning engine. Depending on mileage as well. Valve train or loose injector hold down bolt can cause low compression and high crank pressure

[@MrNicong]

DD13 def deleted showing solid yellow engine warning and cutting engine off. Will restart and run for a a few miles before cutting off again. A couple shops and they can't figure out what's wrong. Any ideas?

Take it to the guy who deleted it.

[@dougbesplug8851]

Do you perform the test with engine warm?

[@TATEXPRESSINC]

Doug, a warm engine would give a more accurate reading. Thanks for watching

Question, i have a 2015 Dd15 approx 540k miles just recently i started noticing some black spots real minimal thinking it was oil i sent it in to Freightliner they did there test compression test and they stated it was Burnt Down Coolant. Is that the cause of it ? Thank You ..

[@TATEXPRESSINC]

Trokero, thanks for watching. Is the engine consuming any fluids? Coolant or Oil

[@jDaniel-90]

TAT Express Inc. Negative ! I did a Oil sample on coolant before i purchased it .. no oil but it did state the test was cloudy so they changed the reservoir for me but im sure they didn’t do a proper flush ...

[@TATEXPRESSINC]

Trokero, you are having black spots in coolant bottle. Does it look like it’s getting worse or staying the same?

[@jDaniel-90]

TAT Express Inc. im sure they just replaced reservoir & added coolant not drained the full system. What do you recommend ?

[@jDaniel-90]

TAT Express Inc. i took it to shop after i started seeing the black spots (Minor) i am going to monitor it closely & hope they dont keep pooping up

Roberto, we see a lot of engines with low power due to bad deletes. Have you do the compression test?

[@robertoalonzo785]

@@TATEXPRESSINC Don't think so. What's the purpose of this test?

[@robertoalonzo785]

I usually deliver around the metroplex area. I live in Mission TX. Can I just stop by at your shop and get it checked out? How much is your rate per hour or diagnostic?

[@TATEXPRESSINC]

Roberto, we can definitely help. A compression test will give us a idea of the condition of engine. If compression is good we can test fuel system and check for boost leaks.
