Well,how do i fix it?? And what is it?

 

Depends on what it is. If it is blow by then you probably have bad compression in one or more cylinders. Typically that means a rebuild or new engine.

The choo choo thing is not 100% conclusive though. A steady puffing is OK while heavy puffing with some force behind it points to a bad hole. A compression check will put all speculation to rest. A scan tool will not tell you about the compression but it can point you towards a bad cylinder.

 

My predator acts as a scan tool and picks nothing up.. I will post video in a few hours and yall can be the judges!

 

My predator picked up codes:

p1316 Injector driver module codes not detected
p1212 Injector control pressure lower than desired
p1248 Turbo boost pressure not detected
p0470 Exhaust pressure sensor

and the video of the oil cap test:

So what are the codes,how do i fix them? And what do you all think of the OIL CAP test?? Please let me know ASAP!

 

People LOOK!

 

P1316 Injector circuit/IDM codes detected-Injector circuit failure/IDM codes detected

P1212 ICP voltage not at expected level-Biased sensor or ckt., open signal return, low oil in reservoir

P1248 Turbo boost pressure not detected- MAP hose, sensor, EBP sys, intake leaks, turbo

P0470 Exhaust back pressure sensor circuit malfunction-Biased sensor, open signal return

I would clear all them codes and see which ones return.

As for the oil cap test, it is not exactly blowing the cap off. I have seen a lot worse but I have also seen a lot better.
I would focus on the first two codes above for now. Have you tried unplugging the ICP sensor when you try to start it. Might want to see if that sensor is bad or has a bad connection.

 

Easy there fella, I know you are frustrated. Folks who can offer assistance will when they get a chance.

 

How do i clear the codes? If they come back,how do i fix the first two? Thanks for the input!

Also what is and where is the ICP sensor?

 

Your scan tool should have an option somewhere to clear continuous codes. I doubt the IDM code will return, at least I hope not. If 1212 returns here is some food for thought:

<link rel="stylesheet" type="text/css" href="V1C%7Eus%7Een%7Efile=V1Cstyle.htm%7Egen%7Ere f.htm">DC14 CONTINUOUS DIAGNOSTIC TROUBLE CODE (DTC) P1212

• Note: This code may set after a high-pressure oil system repair (i.e., injector change). Drive vehicle to clear air from system after repair, and clear code.
• Continuous DTC P1212 indicates that there was no ICP detected during crank (long crank time).
• Possible causes:
  • high-pressure oil system repair
  • empty/low oil reservoir at crank
  • low engine oil level or incorrect viscosity
  • IPR circuit fault
  • damaged low-pressure oil pump
  • damaged IPR valve
  • damaged ICP sensor
  • damaged high-pressure oil pump
• Check engine oil level.
• Perform KOEO On-Demand Self Test to verify ICP/IPR circuit faults are not present at this time.

Are KOEO DTCs present?
<table border="1" cellpadding="3" cellspacing="0" width="92%"> <tbody> <tr> <th width="50%">Yes </th> <th width="50%">No </th></tr> <tr> <td width="50%">REPAIR KOEO DTCs before continuing. If DTC P1212 returns, GO to DC15 . </td> <td width="50%">GO to DC15 . </td></tr></tbody></table> DC15 CHECK OIL RESERVOIR LEVEL

• Note: If vehicle stalls after start and reservoir empties, oil is not being supplied from low pressure oil system.
• Verify correct oil level, quality and viscosity.
• Check oil level in oil reservoir.
• Verify Steps 5 and 9 on the Hard Start/No Start Diagnostic Guide have been performed.
• Clear DTCs.
• Monitor ICP V PID while cranking.

Is ICP V reading at least 0.85 V within 5 seconds at crank?
<table border="1" cellpadding="3" cellspacing="0" width="92%"> <tbody> <tr> <th width="50%">Yes </th> <th width="50%">No </th></tr> <tr> <td width="50%">DTC is intermittent. GO to DC19 . If other DTCs are set, SERVICE them first. </td> <td width="50%">GO to DC16 . </td></tr></tbody></table> DC16 CHECK ICP SENSOR

• Disconnect ICP sensor harness connector.

Does vehicle start?
<table border="1" cellpadding="3" cellspacing="0" width="92%"> <tbody> <tr> <th width="50%">Yes </th> <th width="50%">No </th></tr> <tr> <td width="50%">REPLACE ICP sensor. RESTORE vehicle. CLEAR DTCs and RETEST. </td></tr></tbody></table>
I won't post the rest for now. The ICP sensor is on the front of the driver side head on the valley side. Let me see if I can dig up a picture.

 

 

bump bump..

 

Yep -- get a compression test done. Looks like you're working on a weak cylinder or two. I wish I would've video'ed my buddy's Cummins -- he melted a piston trying to keep up. His was blowing oil & the cap FLEW right off every time no. 6 came 'round.....

 

How do i do a compression test? And if a cylinder or two is bad,how do i fix it?

 

Gee, thought I posted this earlier.

 

So,i have to rebuild or get a new engine?
