I was driving slowly push down on gas car would not go. Is it fuel issue? I replaced the filter head and kept fuel heater unpluged. Im heading off to autozone to get scanner. Will report back, Im located in SLC Utah any specialist for VM motori?

Not much information to go on but it's possible you have low boost due to a split turbo to intercooler or intercooler to engine hose, especially if you are not running Samcos or 2nd generation OEM hoses. Split usually occurs on the underside of the hose and often cannot be detected without removal of hose. If I recall this may throw the engine into limp mode.

Just a reminder you are almost due for a timing belt change so best start collecting parts. Look at Gates belts (serpentine and timing) as they are just as good as OEM and a lot cheaper.

I've had a couple of no-go limp mode - turn it off back on and it eventually works

clogged fuel filter - replace + Powerservice and it's fine
only takes 1 tank of bad fuel to clog a filter.

Maf was connected for last 15k miles so no check engine light. Codes P0299 turbo/underboost,p0401 EGR flow insufficient. The plastic thingy on top motor is caked with oil.

Sounds like you blew a turbo hose and oil got on the engine from what you describe.

back left hand side. Oil all over it maybe part that connects to crank case, PCV? I did see some oilly looking stuff on oil filter which ive never seen before. It's raining hard or I would get under and have good look. If it's turbo hose which one should I be looking at. 1 on top radiator lest side is newer while other's are original. Did not see crack from top.

You should pull both the turbo to intercooler and intercooler to engine hoses (the equivalent of the pretty yellow ones at viewtopic.php?f=98&t=51045) for a manual inspection. As I understand it the failure is commonly in the turbo to intercooler hose, usually on the bottom, and generally cannot be felt with the hose installed. While you are at it disconnect the air cleaner box to turbo hose (remember to pull the hose that runs from the CCV "hockey puck"; click to zoom in on the 1st image on the link above and the puck is the flat round thing that looks like it's just in front of the transmission dip stick) for inspection as that hose is prone to rotting. See viewtopic.php?f=5&t=60636&p=672755#p672755 for a discussion of the issue.

If any of the hoses are bad. I favor Samcos for the turbo/intercooler hoses but understand there are 2nd gen OEM ones that are ok. See see viewtopic.php?f=5&t=51797 for a discussion of this topic. The air box to turbo hose is dealer only and runs about $60.

If you try to clean the oil off your engine use a decent engine degreaser but when washing that off do NOT use high pressure, especially don't use a pressure washer, there have been several folks who did a pressure cleaning only to have strange electical problems due to water in various connections.

Ok I have a feeling what might be going on. Could it be possible that in stock form it will load up hockey puck thingy on top motor? What parts can I clean out, motor seems to use alot of oil just were is it going. All items you think I can clean out with pictures would be sweet. I plan on cleaning out boost sensor done that few times. I unplugged the MAF again and plan on running it that way. Before the egr leaked oil out seal and dripped on concrete this EGR was replaced by Dealer. Every time my jeep goes to dealer they screw something up. I drove up Parley's canyon to clean out and romp jeep, nice black smoke.

Welcome to the forum, you should really read to noob guide:
viewtopic.php?f=5&t=54207

It sounds like you may have burst intercooler hoses, you should remove them and check for tears and splits, there's a decent chance you will find that you need at least one new hose.

X2 on Sir Sam's comment

Based on a 6,000 mile oil change interval mine uses zero oil between changes. However, the manuals are incorrect as to the amount of oil needed for a fill in that they call for too much oil. There have been reports that this overfill will result in excessive oil consumption. As I under stand it with a stock filter (ex. Wix 51516) the correct amount is 6.3qts and with a large filter (ex. Wix 51515) it's 7qts. Also be sure to use a diesel rated synthetic oil such as Mobil 1 Turbo Diesel or ESP or Shell Rotella T6 Full Synthetic or a name brand equivalent.

Generally speaking engines "use" oil by burning it (bad rings, cracked head, leaky valves, dumping it into the combustion stream via the CCV, etc) or leaking. To look for leaks clean your engine (keep in mind by earlier comment about excessive pressure while cleaning); drive; look for oil to reappear. It may be possible to add a UV dye to the engine oil to aid in leak detection. However, if I was to guess there is a good chance you are overfilling; blowing the excess thru the CCV; noting the oil level on the dipstick (which is mismarked) is a bit low; adding oil for a repeating cycle.

I don't have a clue about the guts of the CCV or whether or not it can be cleaned. The old PCV valves could be but they are a different animal. If intact the turbo to intercooler; intercooler to engine, and air cleaner box to turbo hoses can have their interior and exterior cleaned although it's a nasty messy job with an oil solvent or engine degreaser (NOTE if the turbo to intercooler hose is intact but soft and saturated with oil it's time to forget cleaning and go for a replacement just like for a squishy coolant hose)

Oil was off dip stick so grabbed quart and tossed it in and went on my way. Well checked again during day and needed more fluid! Maybe the turbo is loosing some oil, and lines to egr. Not really sure I did read up on all the mods couple years ago but lost interest in whole thing. What would it cost to do elephant provent mod and this GDE I hear about. I am thinking about trading jeep in I owe $15k and just need to find something 4x4 large enough to replace lol not happening. Maybe 2wd Jeep Patriot? IM going to change oil tomorrow see where black stuff came from. Recommendations on filters? Factory $15 bucks and scarred about using anything but factory filter. Motorcraft did not seem correct. I think ive been going 6.7 quarts just received mobil one 0w40 $5 quart not bad.

first off the CRD must sit for a very long time, preferably overnight, to get a good reading on the stick.
Then if your filling it to the MAX mark your overfilling it and it will throw the first quart out. There's nothing on paper about it but most think the dip stick is marked wrong. I suspect it's possable that MAX is on there to warn you not to put any more in and not to meant to mean "FULL" like we're used to seeing.
As pappaindigo said, on a change it takes 6.3 quarts with the filter :rockon:

Ok no engine codes stored after rommping up steep long grade. Just changed oil yuck messy sucker. Added factory filter and 6.5 mobil one 0w40 .2 should be ok. That's good advice on checking oil level after sitting day maybe that's why at gas station it got me worried. Im leaving Maf unplugged this time. The old filter looked like it was puking the gasket and leaking little bit. Ive changed lots cars over years never had that happen. All seems good knock on wood should get me through to winter.
