2001 dodge ram 5.9 magnum oil consumption loosing oil

ok i know this was a stupid part on me but i ran out of money and needed my truck ok i completely rebuilt the engine all new gaskets including the plenum gasket the only thing i did not do was ring because i had great compression so i didnt bother with them and my rod bearings and mains were perfect condition i did new timing chain and all new gaskets and seal every single one of them from oil pan to head gaskets and plenum,now it runs great oh and i did all this 2 months ago now it started to smoke when first started up after sitting all night when i gave it more gas more smoke came out the pipe also if u really get on it meaning floor it white smoke comes out, i took out the plugs to have a look, all look dry except number 1 it had very very little almost none what appears to be a little oil on it i mean not hardly any just enough where it looks a little wet i even did valve steam seals too so ruled that out i cant figure out whats up so i thought maybe pcv valve so i changed it out with a BWD brand well that sucked because when u start it all u hear is it rattle so i put the stock one back in no sound ok now this morning after i cleaned and cheacked all plugs oh and the number 1 the tip gap was almot touching the tip of the plug weird idk why but i gapped it anyway thinking it was a pistom problem started it up and took it out again to check all is fine hummm dont know why it was anyways can any one or has anyone ever had this problem before oh and i hope im in the right place im new here and i love my truck its all orginal and i have every piece of paper work on it 2001 dodge ram sport single cab 2wd 1500 5.9L magnum thank u all i forgot to mention im loosing about a quart if not two every 50 miles maybe less but it dont smoke when driving normal its really weird to me never have i seen anything like it oh and no oils leaks at all

Well, my first thought is a blown plenum. How did you replace that? Valve stem seals? Going through coolant or just oil? Any codes on the computer?

If it only happens overnight, it's more than likely the valve stems. Oil seeps down over night and burns out on fire up, the WOT white smoke is coolant or condensation.


I'd pull the valve covers, remove the rockers, springs, and replace the valve stems.

I'd also verify that no contact was made to the cylinder 1 piston, and re-check compression on that cylinder. If you ran with your gap on the plug that close together, you might have washed out the rings with fuel.

I'd also check for milky coolant, or do a leak down test.

If you're losing 1-2 qts every 50miles you have a major problem. 1 qt every oil change or 1,000 miles isn't too bad, but 2 qts in 50 miles is bad.

i did recheck the plug it was fine also everything is new all valve stem seals are new head gaskets are new i mean everything besides the rings rod and main bearing cause they were all fine but i will check the compression on number one and make sure just have to go out to my shop and get my gauge i will let u know and it cant be condisation cause no matter what time of the day it is if i stomp on the gas it blows smoke not a whole lot but enought u can see it out the mirror and no i have no coolant loss or oil in the coolant or coolant in the oil its just really strange it didnt do it after the rebuild it just started like a week ago and i have no idea how the plug got like that maybe i misover looked it when i put the head back on idk for sure but i did check it after i drove it and its fine now

oh and i did the plenum 2 months ago when i did the rebuild

oh and also the tail pipe inside is really black like it looks like soot maybe im not sure like u would see in a fireplace also i have noticed one day it will be like i just touch the gas and it takes off with power then another its like a luxury car and dont i also have like 38 psi oil pressure sometimes 40psi and first startup goes to like appears to be around 70 or 80 psi then after warm up back down to 38 or 40 psi is that normal too

sorry guys i forgot to thank u for replying i got carried away so thank u for replying back

Oil control rings are worn. Did you change out the cam bearings? What was done to the heads other than valve stem seals? How many miles on this motor?

valve lash the valves,but if the rings are that bad wouldnt i not have alot of compression and wouldnt the plugs be soaked in oil and build up because i have none except the number 1 has barely any oil and i mean just a tiny amount thats all, i also seen a little bit of black smoke when i got on it today i forgot to mention just crossed my mind the valve seats have a small hairline crack in each one no coolant loss just oil loss and smoke thats all runs great has great power, except when u take off when its cold, but warmed up its fast,and the cam bearings were fine no scaring or any marks on them at all

anybody??

ok so today i started it no smoke what gives ok this truck is driving me crazy i like it but if its gonna give me this many problems im just gonna send it to the scrap yard

Metal expands with intense heat, which would explain why the issues go away during normal operating temperature, however with hairline cracks in the heads, that can play a roll too in allowing fluids to pass through when cooling or sitting for awhile.

Somehow oil is getting into your combustion chambers, and since you said that ~2qts in 50 miles, but the spark plugs only show that one was lightly covered? Means you're leaking oil into another part of the motor, could be the coolant.

You really need to do a complete leak down, and check all fluids in the motor, and when I say check I mean take them down and have them analyzed, sometimes you won't notice the mixture.

Me personally? I would probably start over from scratch having everything checked before being installed.

i just noticed your in ft.worth im in arlington cool my coolant is fine just my oil i loose i checked it tonight and the oil hasnt went down crossing my fingers here and hoping and i drove it today about 40 miles it didnt smoke this morning either so not sure like i said its weird thank for the info not sure how to do a leak down test though i do however know how to do a compression text and have a gauge

It's similar to compression testing, but you're using compressed air. Leak down tester can be bought or rented from an auto parts store.

You will need to read the instructions on the tester to figure out how to zero it out with the regulator, once that is done you will hook up the tester to the line that goes into the spark plug hole. If the cylinder is leaking the leak down test will give a high >10% of how much air is leaking by.

If you have a high % for a cylinder you can hear the air coming out of any the following places;

1. Coolant = bubbles/hiss noise (head gasket/cracked head)
2. Oil cap/crankcase = hiss noise (rings)
3. Intake manifold = hiss noise (bad intake valve/seat/seal)
4. Exhaust pipe = hiss noise (exhaust valve/seat/seal)

It just allows you to pin point were the leak is.

not sure of your name here so im going to call u mopar thank mopar for the info im going to get a tester and follow the instructions and go off what u say may take me a few days as im working so much lately and working on my jeep but i will get back and let u know what i figure out thank u again if u think of anything new please let me know thanks again for everyones help

ok this is what i got dry no oil down the cylinders warmed up for about 5 minutes
#1/ 120psi
#2/ 170psi
#3/ 120psi
#4/ 160psi
#5/ 157psi
#6/ 165psi
#7/ 160psi
#8/ 170psi

to me that dont sound good so what do u think??oh and also it started to smoke again today

ok i feel like a ******** now i just remembered i forgot to hold down the gas when doing this damn it i was in a hurry have to redo it again well thats what i got not holding down the gas pedal dang it

Looks like #1, 3 are shot and 5 is getting there.

Funny, all those cylinders are on one side of the motor (driver side). Makes me wonder if you have a warped head, blown head gasket or simply did not torque down the head bolts correctly.

Did you buy new head bolts or did you re-use factory bolts? Used bolts get stretched, I don't like re-using them. I use ARP head studs or ARP head bolts. If those heads or gaskets did not seal correctly due to the above issue(s), that's your problem.

I'd run the test a few more times to get a good average and isolate any irregularities in the data.

Head gaskets = Felpro 1008
Head bolts = ARP 144-3605 (could be wrong ARP likes to change PNs all the time)

My money is on head and/or bolts too.

i did however reuse the bolts and retorqued them to 50lbs and then 105lbs from center out i cleaned up all surfaces really good and clean but u sound like u are on the right track i never thought of that well i have 2 extra engines im gonna take the one that originally came out of it to the machine shop if i can find one here that trust worthy and good and has a good price for the block heads and cam im buying a whole new crank kit and this time im getting all new bolts but i will try it again and this time with the gas pedal down lol and i will let u know ok thank u for your help i will post it here for results wish i could afford better heads but with two kids its hard
