Oil leak getting worse quick.

[SAYiWONT]

I have a oil leak thats getting bad quick, friday i drove truck to work and the puddle was like size of a baseball. This morning theres like a pool of oil now!!!! I saw oil in valley but its also everywhere under the truck. My friend thinks its a RMS and it looks like it but ive heard pedestal o-rings can cause that. Where should i start? Its quite daunting and i dont have money to make mistakes.

Get some degreaser (I like Simple Green) and spray off everything with a hose. Then clean up everything with rags including soaking up the water and oil in the valley. Wipe down everything. Then turn the motor on and look with a flashlight and mirror, especially around the HPOP and oil lines, and turbo pedastal. WIth a puddle that big you should be able to track it down easily.

I have a small leak but it's only under load, so I think it's something in the HPOP system.

So clear everything outta the valley? Wheres the hpop below the turbo?

HPOP is in the valley at the front of the motor ( in front of the fuel bowl). Look deep. If it and the ICP are fine check the two hoses coming of of it. Next follow them back to each head and check along the heads as there are several plugged ports that could be leaking also.

There are two sets of turbo O-Rings though generally only the lower ones (between the pedestal and valley cover) wear and leak.

Also, if the turbo's never been messed with put your hand on the EBPV (exhaust butterfly between the turbine housing and down pipe, under side), then move to the actuator rod, follow it back behind/under turbine to where it meets the turbo pedestal. Feel for oil.
Since you're not complaining of drivability issues, besides the leak, I'm leaning on turbo leak.

Thanks alot guys, ill try that next.

Also im stumped on another issue aswell, my coolant temp guage sits on dead left when im running the truck. Ive notice tho that after driving for about 20mins it will slightly move over some. At first i was thinking its prolly a bad sensor but now im thinking maybe the thermostat is stuck open. Any input?

I had one of the o-rings on the hose ends in the hpop go bad. I left for florida from ny and you couldn't see it or find it. Pulled over in va and the oii was leaking faster than the ac under the truck. Used 6 gallons there and back and found the o- ring bad. Leaks real bad when running and wdnt the length of my truck and covered the back in oil.

Mine got worse today in fact. I think I have it tracked down to the CPS sensor o-ring. But today I started pulling the HPOP and replacing all of its o-rings, the oil hose o-rings, and the head plug o-rings so I know it'll be good.

I'm also pulling the turbo to do the pedestal o-rings, the compressor wheel, intake boots, and up-pipe gaskets. Should be a couple day deal.

I had my flywheel cover rub a hole from one side of the pan to the other.

If the truck isnt actually running hot, dont sweat the t-stat (rarely fail). It will be 110* + out here and my gauge barely will show a rise in temperature. I think they just run that cool.

[SAYiWONT]

Yea ill just do a compression test on cooling system and do a flush.

I cant believe it rubbed a hole like that. How quick was your oil leak?

[Cml390]

It started out slow, but once it rubbed all the way through and if i parked nose up on any incline with the truck running it would come out at a pretty good steady stream. I originally thought it was a HPOP because i would back in the drive way, no leaks. pull nose in ,leaks. Checked the valley bone dry. Then thought Rear main seal, dropped tranny to check and a nice u shaped hole was smiling at me. I used JB weld to fix it (should have actually welded it), but no problems so far.
