To the best of my knowledge the inlet tube was not removed doing the rear seal. It was not removed until I went over there trying to help troubleshoot . The o ring is accounted for and intact on the end of that inlet tube; I suspect that O-ring was flattened out and hardened to the point that it is not sealing on reassembly, Causing the oil pump to suck air at low RPM instead of oil, Due to lower suction at lower RPM...

Is this a plausible theory, or would you recommend looking at Replacing the oil pump, or???

It was removed primarily to replace a rear main seal. When out, they did a tune up, new rear seal, pan seal, and when it was reinstalled, I discovered a leaking water pump. We got that replaced, and when we tried to start it, we encountered our first issue: the trans selector module. We fixed yhat, but Then when we started it, we had the oil pressure drop. We dropped the pan looking for foreign material in the pickup tube, so we had it out to clean it( but did not replace the Oring).Now, with a new pressure sensor, it's showing pressure, just not at idle. We let it run at 2k Rpms for 5-10 min, and all seems fine, but the pressure drops to zero at idle.

(No abrasives were used. I believe they tried to de sludge it before diassembly with s store bought additive.)

now reassembled and topped off with synthetic, When it idles is when it makes abnormal noise, like a metal on metal shreaking sound, making us believe its truly not getting oil at low rpms

Ok....We pulled the oil pressure sender, and noticed it was leaking oil into the wiring pigtail( probably bumped during engine removal/install) we changed out the sensor, and whalllaaaa! We have oil pressure...at elevated rpms...but as soon as we let it idle, the pressure drops to zero, and we do noticed some shreaking squeals, and possibly some lifter/valve train noise. The needle bops to zero and the DIC check oil pressure warning comes on. No leaks; Everything else is normal.

Wondering if that sounds like an O ring on the pickup tube not sealing properly, or an oil pump, or ???

sad to hear. prayers to the family

Thank you fellas!

I passed this along. Hopefully my buddy will have a better idea/diagnosis...and some parts ordered... for this weekend so we can finish this beast off

I thought for sure it was a plug... i expected to find a piece of gasket/ foreign material stuck on the oil pick up tube inlet, But no there was nothing. If it were the O ring, do the symptoms match ? It does build oil pressure for a few seconds before dropping to zero... One time it held oil pressure for about 20 seconds before dropping back to zero. I would think if it were the O-ring it would never develop pressure at all, But I will have my Air Force buddy check for it Nonetheless.. We are doing the work on the Yukon at his house out in Hemet; I only get out there to help on the weekends, But I'm relaying any advice to them everyday. As for the sensor we are basically out of ideas... Starting to wonder if the oil pressure is actually fine but getting a false read due to electrical Issues? Maybe a bad sensor or a bad connection somewhere?

If it were that bypass relief valve what is the fix? Is that a part that can be replaced Exclusively, Or would you replace the entire oil pump...?

I have heard it run , but shutting it off as soon as the oil pressure hits zero, I really haven't noticed any substantial valve train noise... What would be the fix if that's the problem?

I'm doing a little wrench work on it, and another buddy, a jet mechanic for the Air Force, is wrenching too, but neither of us are comfortably knowledgable about this particular motor, so any details are much appreciated. We are trying to help out the Yukons owner, a buddy trying to make ends meet. We all appreciate your insight!!!

Pulled the pan today; found nothing remarkable. There was a lot of grit/grime in the pan... Considering it had just been wiped clean, but figured we aggitated that loose with the work that was done...don't believe that'd plug the pickup tube.

We're wondering if maybe it's a bad sensor? Any suggestions?

New problem....just a matter of seconds and it drops. It is consistently doing the same thing... Thinking about hooking up a manual gauge to verify its really at zero; not sure where to hook one up if we go that route?

Well, the 7 wire pigtail O'Rielleys sold us was the wrong one, so he picked up the right pigtails at the delaership. He got it wired up and, whalla, she fired right up, and the indicator works, but still does not show the park position...Is that just a matter of an adjustment? eitherway, that solved our not starting problem. Glitch #2 is when we fire it up, the oil pressure hits 20-40, then back to 0. We've shut it off each time. The oil level is full, with a new filter, and no leaks...I'm thinkin a bad sensor, or perhaps something foreign is getting sucked up in the pump. The problem repeats evry time we try.

I installed a RINNAI tankless water heater in my house about 5 years ago or so....Absolutely love it. We did a masterbath renovation, tearing down some walls to open the master suite up, which included a clear glass shower room, with a couple of shower valves/heads, and a huge whirlpool jaccuzzi tub right across from the bed. We found the old tank style water heater would run out with both shower heads going, and it also would run out towards the top of filling up the tub; so that's why we switched. Now, we have an endless supply At the time , I found the best reviews on the Rinnai, so I searched and found one on ebay. Fairly easy to install. We have a natural gas model though. We still saw savings though. Our summer gas bill was as low as about $30, and after it gets down to about $12 a month. The savings so far have paid for the whole unit, and it is still going strong, and will for years to come I'm sure. We have ours set at 140(max). Should I find myself in another house, I will never buy a tank unit again! I would reccomend anyone who needs a water heater to switch over

We were In Glamis for New Years week in GLAMIS.Got stoped twice by the Rangers once they thought I was drinking and driving NOPE !!

Second for a Sticker check !! Which there was a CA sticker in plain sight on the back !! Also my buddy rolled into Gecko with two brand new Quads

No sticker yet because I had them at camp.They were taken and impounded at the entrance. Still Great Week !!!!!!!!!!!!

I would've been livid...Especially when you have the stickers, but not on the bikes...and for brand new bikes...REALLY? My mouth woulda earned me a night in the pokey I'm afraid

Thats just it, this is doing nothing.....a vin with no title is nothing. Im going to take my little vw powered homemade rail, a chinese 50cc quad, a 50 cc pit bike, and my daughter 8 volt power wheels quad and her new rangerover powerwheels jeep and ask for vins at the dmv. She rides them off road, they were never intended to be on hiway vehicles......this should get good. Im gonna ask for a supervisor and a writen and noterized reason why they wouldnt issue a vin to a plastic toy for the rangers, so I could get my offroad sticker.

I think I might even video it.....its all about revenue anyways....since they wont give titles so they should vin a folding chair with a blender motor if ask just to make a buck.

I love it!!! Gotta get my girls' 12v barbie jeep legit

oh crap, sorry to hear. I didn't get hurt as bad as you when I fell, but being broken sucks eitherway. I was on NORCO...that stuff was AWESOME! My wife took me to a party after a dose, and she said I was hilarious Hope they keep you well "medicated", and listen when they say to rest...I didn't and I'm still paying for it

Heal up; it's dune season

Didn't get the pigtail after all... We'll try again next weekend

Thanks for the replies; re confirmed what we were guessing. We thought someone else had glued in the pigtail though... Never would've guessed government motors did that nonsense at the factory. A buddy said he had wrenched on the pigtail a bit to get it apart, so more than likely the damage was done then; so a simple wiring job and we'll be up and running. My pals Yukon has 240k, and a leaking rear main seal was all it needed. I just hope once we get it back together, it holds out for him ;p

Thanks again! I'll get out a victory post once we are up and running!!

Definetly didn't get pinched. He said they struggled with it coming apart. Maybe a problem with the pigtail. We found a new pigtail at O'rielys. We are gonna head there now and try that. There's a four wire and a 7 wire connector. O'rielys has the seven, so we'll start there.

Thanks SS

DDR , I need your help:

A buddy and I are working on his 2000 gmc Yukon ( suburban)

His rear main seal was leaking, along with a few other problems. We have pulled the motor and fixed everything, put it back together, and Houston, we have a problem...

First, we noticed the transmission indicator in the dash doesn't identify which gear it's in; when the key is first turned on, it says its in prk for 3 seconds, and then the highlighted square disappears.

Second, we noticed it doesn't start; it doesn't crank a single bit. When the key is turned, the starter does nothing, not even a click. We have checked the starter, and it is fine.

We guessed that the module on the side of the trans was the trans positioning sensor, and that it was defective, so we replaced that, but no luck. We went over all the connections, and everything looks fine. I'm thinking the two issues are directly related, but I'd appreciate any advice or suggestions as my buddy needs this vehicle in a bad way.

Grub n lube

Yah, the glamis SS were out in force, like I haven't ever seen. I was at the drags on sunday, and although all my stuff is legal, I got outta there...I just don't want the hassle. The same thing is true in the commercial enforcement; out of state trucks get hassled, but with our new diesel emissions, us locals are now enjoying the bendover too :porn: . Sucks for your buddy, sounds like nothing but a money grab

Glamis Heck, I'm excited just to get out to the sand, I can't pay attention to details like the thread title

All I can pay attention to is how I hitched up the trailer.................................Well, hopefully this time I'll do better

Both of my groups should be at Glamis, and we'll be there fo sho

fricken awesome

Great video ... Miss my 3 wheeler too; my very first toy was a CR500 (slightly modified)

Adam, when I upgraded mt wife's raptor, I put the stock stuff on craigslist. It got a lot of attention. I wasn't sure what they were worth, so I advertised them at $150. That might have been too cheap based on the quick response I got, but I was stoked to get $150 for what I didn't want anymore!

I did a 3+1 with elkas on the front, and holy cow, it's a complketely different bike You're gonna love it!

Nice!

I noticed the Steve watermark...ain't nobody gonna Jack yo goods anymo

very interested in this...keep the pics coming! I'd like to hear how it handles/corners/etc. once you are done
