Small diesel engines like the 3024C/C2.2 have glow plugs. Using a glow plug adapter is a bit easier than having to remove injectors.

Always informative thx !

Hello good video thank you Im your fan from now on Keep up the great job…!!!

Thanks as always.

Great info!

Great tip!

Well that just went from an easy fix (injector replace) to a major job. But, at least you were able to diagnose the issue.

+easytopleez33 It is better to fix it right the first time than to replace the injector, then have to fix it right afterwards.

Hey Josh, been watching your videos for a couple of years now and I don't think I've seen a video on how to break in a diesel engine. I'm an apprentice mobile plant mechanic over in Australia for Komastsu and just finished rebuilding my own motor for my Toyota landcruiser hj75 with a 12ht engine swap and honestly don't know much about engine break in. What do you recommend doing and the best way to break a diesel motor in, especially one with a new cam in it. Thanks, Marcus

Good stuff.

Thank you

Couldn't they make a fake injector with a threaded hole that fits into the injector holes (and that uses an injector hold-down bolt)? Then you'd just screw a pressure gauge into the hole in the fake injector and get a reading.

Great video sir! Do you ever use a scope to perform a relative compression check? Ever since learning of that a few years back, I've incorporated it into my regular diagnostic routine. Even when you don't think or aren't yet sure you have a mechanical issue, it's a nice quick check to help narrow it down. Let's you know quickly whether more invasive testing will be necessary. Keep up the great work!

You should also make note that if the piston is on TDC you can also have a issue were it will not rotate the engine, just as in BDC.

Does Cat use a cranking compression test? Or just a leak down test?

What air pressure you asume to be good to do the test if add too little i will never see the engine rotate if add to much i have to see the engine rotate or the valve is super bad is there a average pressure ? By the way you are good doing your videos congratulations i just subscribe

Wow, looks like it would be smarter to take it to a diesel mechanic for me..

Does bad diesel engine compression always results oil consumption (burning) ?! If oil level is ok compression should be ok as well, right?!

Can you help me? I need to know the hp rating of a cat C4.4 engine. It runs a large wood chipper. I have the serial number if you need it.

Can I use a bunks gun (wash down gun) to evac cylinder?

No matter what position piston is in there shouldn't be a loss of air anywhere is that correct?

Sorry for being dumb.....am I right in saying that as its a pushrod 3ngine....that the timing will be ok?.......is this OK to do on DOHC...thanks buddy

I use Rotella T6 5w-40 in my 2009 VW GLI with 220K miles and no issues yet. I also use Rotella 15w-40 in my 06 cummins with 229K miles and so far no blowby but I think an injector or more are going out.

How to take engine compression for Cummins QSM11 engine?

New to Diesels, I recently did a (cranking) compression check. One cyl was lower, so I did the oil in the cyl to see if it was rings or valves. Note to self: Oil ignites under compression. Buy another compression gauge. Is the leakdown method the only way to check if it's valves or rings?

But what a bad head gasket do the same thing nothing to do with the valves but leaking air to another cylinder . I got a deutz 2011 2-cylinder. And everything is backwards on it number one cylinders work the flywheel headsets anyway I'm guessing it's a head gasket I was just seeing what your opinion was

Thank you, but how did you know #5 cylinder needed a compression test, i.e how did you determine the miss was there?

One of the valves was sitting a lot higher than the others. He would of seen it when he removed the rocker gear. It's called valve recession, not uncommon on CAT engines.

I know this is off the subject but I just put a fuel pressure gauge on to test it and it's showing 60psi at idle. Is that too low? Also the gauge bled off fast and I have problems starting it sometimes esspecaly if it's cold or if you don't keep your foot on the fuel pedal while starting. What do you think? Thanks

Not all diesel engines have glow plugs and a C13 falls into that category, It does make it easier for sure when doing a leak down test when they do have them.

Yeah those engines have intake heaters as well as the C7, but no glowplugs... I don't recall seeing an intake heater setup on any other Cat engines either. Trucks in our area rely on block heaters being either electric or a Proheat system. Battery warmers are important also in very cold areas to get the maximum CCA.

These large-bore diesels have such compression that (except for maybe way down at minus40) the air heats up enough enough during the compression stroke for the diesel fuel to ignite. Of course, down at minus 40, it becomes rather difficult. The smaller diesels found in pickups, passenger cars, don't have such high compression, so they use starting aids like glow pins, grid heaters, any trick in the book, so-to-speak, to get the fuel to ignite in cold cylinders. The old trick of using ether to start a diesel can be used on a glow-pin-equipped engine, but the trick is to skip the waiting period for the pins to heat, and begin cranking immediately. Using ether to start a diesel engine of any type can result in serious engine damage if you don't truly understand what you are doing.

Omg diesel engines seem like a pain

The opposite. There ignition system is also their fuel system. Noi coil packs spark plugs throttle bodys with iac sensors in tank fuel pumps to wear out. Older diesels are all mechanical . Very simple to work on . Allot easier then modern cars once you understand them.
