Alright guys i went to check my oil the other day and it was 2.5 qts low! I still had good oil pressure tho. Also i noticed my 4unner was blowing a decent amount of white smoke( i guess from the oil being burned). The reason this is such a suprise to me is the motor is a remanufactured engine with only 10K miles on it. I just changed the oil and it still smokes. Any ideas on whats wrong or how to fix it instead of having to ship the engine back for repair? its a 3.0 automatic tranny. also i had to remove the honeycomb in the catalytic converter because it was almost clogged, a new cat should be here in a few days.

[EDIT]: There has been a fairly loud, ticking/chattering sound from my engine for a few months now and a little bit of oil has always been dissapearing. could it be a worn valve guide?

How is the coolant look, any losein coolant? did the smoke have a blue tint or smell Sweet?

the coolant hasn't moved a drop. the smoke smells burnt like oil and is a greyish color. i know its burning oil but is there any way to stop it? the engine has an unlimited mileage warranty to protect me against stuff like this but i can't see being out of my truck while i have to pull the engine, ship it to oregon, wait for him to fix it, and then ship it back and then put it back in.

How many miles did it take to burn the 2.5 quarts?

95RunnerSR5

around 200...i check it everytime i fill up, i was amazed at how much escaped and i didnt know how or where but now i guess i do...

check the rings make sure they the gaps are not all lined up with each other all the end gaps should be off from each other

could seafoam stop the smoke?

I don't think so Kyle. It sounds a bit beyond some simple fix, that sucks dude but at least you have a warranty on it.

yeah..i wish i'd had the info about 3.4 swaps before i ventured into a reman'd 3.0...oh the possibilities..

hogie:
If you did the head job on a high mileage motor that will happen. You will blow the rings in 6 months.

thook

No kidding? Why is that?

thook

Check your plugs, Kyle?

95RunnerSR5

yeah they look like they have a slight amount of oil on them, not bad at all tho

thook

Yeah, but is any one worse than the other or are they all about the same?

Is this really the case. I just had new valves, timeing belt, waterpump, head G.'s my rig had about 130k on it when it was done. So can this happend to he as well????

timebandit

That or the guides/stem seal's are bad. Believe me, I have had people do stuff like that before. Rebuilt an entire engine and replaced everything every thing but the stem seals/knuaral. Chevy 350 last time.
