We bought a LANG TOOLS # TU-15-53 for our shop. It works well for the VT-365 engine we did buy an adapter with flex hose on it to go with the kit. It helps use the tool a little easier.
We bought it from our local heavy duty truck parts supplier, it was not real expensive.
Hope this helps! |

I have never done a cylinder leak down test on a diesel engine. There are tools to do this test for gasoline burners, I have never even seen a tester marketed for a diesel engine. Now understand, I am not saying is does not exist, but I have never seen a tester for this. Maybe if they are telling you to do a leakdown test, maybe they can tell you where to get a tool to do it with. Plus the tool #. Oh, and while you are talking to them, ask them what the specs are on the leakdown test. I have not seen any manufacturer specs on leakdown test. There again, I am not saying they don't exist, but never have seen any on gasburners or diesels.
I would do what you did, make sure that turbo is not the problem. You can take that turbo hose off and run it, let it run long enough to flush some of that oil out of the exhaust and see if it is still smoking bad. Just take the normal cautions about the turbo and not letting anything close to it. I have found to see if the turbo seal is bad, take the hose off going to the air charge cooler and run the engine, you can see the oil building up in that space inside the turbo, the oil seal that is in the actuator goes bad you will see this.
There is another old school method and it is simple to check for excessive blow by. Take your oil filler cap off, start engine, use a shop rag put over the oil filler tube. If the rag nearly blows off or gets wet with oil real quick and blows off, you know you have excessive cylinder blow by. It takes a little practice, but it does work. Try it with different engines. If the rag just sits there and kind of acts if it is being sucked in and blown out while throttling engine up and down slowly, it is normal. Try it on a known good engine. Even on gasolineburners. With practice, I've found it to work very well and even finds broken rings.
There is a gauge to detect excessive blow by it is a magnahelic (not sure of spelling) gauge, there are specs for it.
With the information you have given us, it sounds like excessive blow by to me. |

| thanks for info Henderson I cleaned out both sides of the turbo and let it run with hoses off for about 5 minutes and no oil build up was found again the baffle tube that connects to the turbo inlet hose smokes bad and it almost sounds like it has a little pop sound coming from it its weird but I am almost positive its a ring problem I did find a leak down tester for desiel engine not sure if I am gonna buy it gonna try that rag test I am sirry it will blow off cause there is a lot of pressure coming from the baffle hose so I am sure the fill tube will be the same but after I do that test I will call jasper and hope the compression readings and the rag test will be enough thatnks again for the help.... I hate the 365 engine nothing but problems |

I think you are looking for a crack case pressure tester like this.
http://www.handsontools.com/OTC-Tools-ZTSE4510-Crankcase-Pressure-Test-Adapter_p_45450.html
Attach to the correct gauge, block the crank case vent hose and run.. compare the numbers to spec.
From the service info
Crankcase pressure using restrictor tool ZTSE4510, max.
1.99 kPa (8.0 in H 2 O)
17. Crankcase Pressure
Measure at high idle, no load.
Clamp off recirculation tube for crankcase breather.
Measure at oil fill tube with crankcase pressure
test adapter. (Figures P and R)
Manometer or
Magnehelic gauge
Instrument Spec Actual

| well I did a compression test today and they where all around 440 except for one cylinder which was 190 so with that and it burning so much oil it has to be a ring problem I called them and told them that they still wanted a cylinder leak test they said not a crank case test but after talkin with them for a while they finally gave in and are sending me new motor not looking forward to that job uggg |
