the idle definitely sounds like it has a miss.
I've seen worse, but the idle isn't right..

Idles smooth...

:doh: apparently there are different definitions of smooth

Golfer, where should i look in regards to that "miss". It's always sounded like that for as long as i can remember. I've never measured the voltage because i live in FL and figure the GPR is useless 99% of the year

You can sit in it and not even tell it's missing. Doesnt buck, lurch, or romp at idle or anywhere else in the powerband.

I agree with golfer. You have one cylinder not firing 100%. Little bit of a miss.

Looking at your vid , if you look closely at the blowby its looks like it's chuffing. Indicating to me it's got a week hole. The blowby should be smooth and steady with no pulsation.

Do a compresion test and find out. Other wise your just guessing.

Anyone rent out compression testers ?

just ran a cct, all came back good.

cct can go either way.. it tests and makes sure every cylinder is working equally. could be equally good or equally bad... I would check gpr voltage. unless the motor is at operating temps then the gpr will activate. but I would strongly suggest doing what golfer says and get a compression test done...


im on my phone so I cant quite make out the miss from the video. but I do hear a hesitation every now and then..

Im with Swaan and golfer- a definite 'chuh, chuh' when the camera was at the pipe. My motor doesnt go quite that far, but its idle note changes a little as the oil goes from cold to hot. Not quite as smooth..

 

[lincolnlocker]

I heard it now... it does have a very slight thump to it... I had to put my phone on my bed and go across the room to listen to the clip to make it clearer...

whatcha think it can be

 

[TyCorr]

The miss? An injector not working or you have a bad hole. If it followed the injector swap and didnt do it before that I would lean towards that.

Its all guessing until you get those injectors sent out or do a ct or both.

Harbor Freight sells a compression tester kit for about $30. You have to make an adaptor out of an old glow plug, short piece of tubing and one of the adaptors in the kit though.

just throwing this out there but with all the issues I have been having with my dually and the cam moving, I can make idle changes by shimming the cps or removing shims...

You gonna blow it up so you can fix it?

been in NY working for about a month and a half now.. not home to do so in other words.

ok guys, thread revival. Finally got a chance to pull some compression numbers.

2=400
4=450
6=450
8=400

1=450
5=450

For some reason i couldnt get the adapter from the kit to thread into 5 and 7, dont ask me why. The glow plugs would thread in fine no problem. Threads didnt look jacked up or anything.

How do the numbers look? There is a guy local that i just talked to and he swapped from pis to FFD injectors and is having the exact same issues as i am. So i'm thinking compression is fine and its and injector issue
