Volvo D13 misfire on cylinder #5

D13 has an option for a compression test only for informative purposes still have to do mechanical test to confirm something is wrong had injectors give false reading a few times also sometimes like jay said engine brake pistons get loose and keep valves open or remove clearance all together.

 

I have 2013 Volvo D13 engine
My engine is overheating when I drive to hills or I have a heavy load
In my dashboard I have 2 engine lights on
Malfunction indicator lamp failure and check engine fault . i have change clutch fan thermostat and temperature coolant sensor. The problems is still there . It’s only happen when I am loaded and driving in hills .

 

Ok here

 

I have a 2014 Volvo D13 that was diagnosed with a clogged emissions filters, bad wiring harness, and was driven in limp mode for about 150 miles, Volvo never said anything about bad compression. We drove it to our normal mechanic did all the prescribed work and also changed out the injectors cups flanges crews. Finally all done the bring the tech guy out to reset the regen, each injector (not a Volvo guy), he is an independent my mechanic uses. He claimed that the injectors are fine but some how all the cylinders have little or no compression except cylinder 5 which is perfect.

he said there was blow by like crazy. I went out had him turn it over and it was idling terrible, I saw no blow by out the valve cover opening was and I am wondering with only one good cylinder with compression can this thing even start cold? They recommending an in frame at 388k and blaming it on driving it to long with the engine light on, basically all the back pressure frying the ring? Any recommendations? a.bain@stealtharmorsystems.com

I told them I am having a Volvo tech come out to be sure before spending the money any thoughts? Need some advice

 

Easy diagnose so you know properly. Pull injectors and do mechanical confession test. Should let you know what’s going on with it.

 

So what is the solution to fix the joke brake piston problem

 

The solution is very simple you can replace engine brake rockers, or you can remove all pistons and use spanner to tight them down with locktite a little and should be fine also hell of a lot cheaper than replacing rockers now they come tack welded so they do not back out.

 

Hey so I’m having the same issue with the knocking sound. Did u get to the root of the issue?

 

U replaced the head? That fixed it? U were loosing compression from the valves maybe?

 

Hey! Thanks for this information. I’m having this same issue along with a rattling/ticking knock sound on my 2014 International 4300 MFDT. After reading this post I did a little research about what a Jake brake is. Can u give me a brief explanation on how a Jake brake can cause compression loss on a cylinder?
