Oil leak?

[04jckhmr]

So I have noticed my 04 4R is burning a bit of oil, or leaking. Either way there is oil missing every 3000 miles I change it. Has anyone else seen this? or know why it could be happening? I have 62k on it and it is about 1 qt or so that ends up missing.

1 qt missing every 3000 miles? That's too much. Is your exhaust smoke looking normal? Do you see oil spots where you park?

My 2004 V8 with 60K miles is not missing oil.

Exhaust smoke looks good. there are no oil spots where I park, from what I can see there is no oil around any of the gaskets....heads, engine block, etc.

What kind of oil are you running?

 

[04jckhmr]

I am using the castrol motor oil.

I am using the castrol motor oil.

What grade/weight?

Oh god, sorry...... I am using the 5w-30 as recommended.

Sometimes some of the oil stays in the upper cylinder. That's been my case running the Castrol Syntec 0W30 because at other times I get a normal reading. It could be you have a miniscule (almost undetectable) issues with a leak around the rings or an issue with one of the piston walls. That's going to happen after the oil has sheared, even at 3000K. I've used Restore in the past and that has helped. Another one that helps more with the rings than the pistons is the Lubro Moly Motor Oil Saver (Napa is where I see this stuff more often). It can't go anywhere else. The only other thing is to run the vehicle for about 15 minutes from a cold start (that should get it fully up to warm temperature) and see if you see anything, then take take it around the block a few times, come back and recheck with the motor on.
