I was under the impression that you pull the glow plugs to do the compression test and not the injectors. Am I wrong on that?

Normally, yes, but this engine seems to be an exception to most rules. The adapter listed in the service manual is VM.1072A, which goes in place of an injector. You may be able to find a place that rents them out.

Another option is this Harbor Freight kit. I haven't heard of anyone here using this so I don't know for sure whether it would work, but it at least lists an adapter with the same thread as this engine's glow plugs (M10 x 1.0).

Interesting... do you know of any write-up that explains the process for testing this particular engine?

So my plan at this point is to ship off the injectors to FL (http://fuelinjectorclinic.com/flow-testing) for testing and cleaning.

In the mean time I will pull the valve cover back off to see if any of the rockers fell out of place.

Can anyone suggest a good method of re-installing the valve cover without knocking any rockers off?

Also is there anything else you suggest checking while I have the valve cover off? I really want to make sure I get it right this time so I don't have to repeat this process again

don't remove valve cover yet , wait for injectors to come back from fuel injection shop, if they pass then you can do compression test in mean time , or , cylinder leak down test .

Any good write-ups or videos on doing a compression test or cylinder leak down test? I lack experience with such things, but I do ok if I have some instructions to follow

are these guys DIESEL specialist ? or GAS ? do you trust them ? are you sure , did you call them before shipping your injectors to them ????

yeah, I hate to say it, but that price doesn't sound right for a Diesel injector.

Also, OFI does mail-in testing as well. https://oregonfuelinjection.com/services-repair/fuel-injector-rebuilds-testing/
I think the injectors will all fit into one of those flat-rate boxes from the post office. Just make sure to seal each one in a plastic baggie with bubble wrap around, so they don't beat each other up, and they don't leak and cause a Hazardous Material incident en route.
Regardless where you send them or take them, make sure to attach a separate label indicating the cylinder number they came from. Don't stick the label to the injector it's self, use a wire, like a twist-tie like for produce bags in grocery stores, with the label on one end and the injector on the other. This way they can test and not worry about ink coming off or stuff stuck to the injectors during testing.

Any clue how much OFI charges?

I emailed them and here was their response
"The price to test the injectors is $48.00 each.

The testing puts the injectors through all their paces from idle to full load fueling and compares it to Bosch specifications. It also checks the return fuel rates and checks them against Bosch specifications.

There is not a good way of cleaning them without disassembling the injectors, we do not rebuild them here so we don't take them apart.

Normal service life on those injectors is 150,000 miles. If you are there or getting close to there you may be looking at replacing them."

I'm at 154,000

If you suspect that you are having injector problems, then its best to have them tested before deciding to replace all four. Injectors are expensive.
There are lots of shops that specialize in diesel injectors and injection pumps. You may be able to find one in your local area and ask them about testing.

I've got over 200,000 miles on my injectors and they are still working good.

Good to know... It just feels like such a gamble. If I pay $200 to have them tested and they are bad then that's $200 down the drain

It's rare to have all go bad.

Usually just one or two if it's running really bad.

Also, it allows you to know which if any are bad, preventing you from wasting money on rebuilding ones that don't need it.

it also allows you to have actual knowledge of the condition of all of your injectors, so you have an idea if replacing more might be in your future, and which.

Having that information, to me, is quite worth the cost. Plus if you have both testing and rebuilding done on them, you might push them for a discount. Worth a try...

I found a place in OK that will do just that. They charge $45 for testing/cleaning and if one is bad I can apply the $45 to a remanufactured one @ $360

I'm thinking I'm going to do the compression test first before spending the money on testing/replacement. Seems like if I have compression issues that is the bigger problem to worry about right now.

That's good logic.

yes the compression test is a very important step , but why does this engine start and shut down and smoke like that , did anyone check any fault codes, we dont know rail pressure value . yes if for some reason one of the cylinders misfires due to bad compression , why is not running on 3 cylinders ? but i guess we do skip basic tests some times . like some times if there are no special tools available , i did say that following fire order 1342 and blowing compressed air into cylinders will tell us something , at least save money on tools and testing injectors , so if needed to save 200 dollars , so removing turbo end exhaust manifold , and trying to start it that will tell us where the smoky cylinder is. i know it is nonsense but i did this long time ago just to save money . im ok now i have lot of special tools lol.

rankom · **Posted:** Mon Oct 09, 2017 12:58 pm

did you make any progress ? im not sure if this tool works on our crd , it is MILLER 9011 injector block off tool 24 $ not bad price . it is worth a try , to start capping injectors one at the time , will save you money and time . it is one way to see if fuel rail pressure can increase and may be lucky to get it running and stay running on 3 cylinders , so you will know with cylinder is in fault. so this will skip buying expensive scan tools, commpression tester , and injector testing , so it is only 24 dollar tool .

Thanks... I ended up buying the compression adapter and for some reason can't seem to remove it from #1 cylinder. I can twist it back and forth, but it won't budge vertically. The actual injectors came out easily by hand. I'm at a loss as to what to do at this point

no problem from now on you need to take time and be patience ,not sure what type of comp tester you use that got jumped so bad , but you need to make some type of puller to remove it up if you need to take some picks go to machine shop ask them what they think about it , then you can fabricate that tool and pull it up and trow it in garbage , and we will come up with something to get it to run again , dont break anything just take your time

hey buddy , did you manage to remove that compression tester tool out from no 1 injector hole ? hope that there is no damage to injector cup .

First start in over a year. Doesn't sound right?
