Burning Oil, from where? Options

[hurley97]

ok, I'm already working on the issue I just want various opinions to work with in case I run out of ideas.



recently my car has been going through oil like crazy. here are some of the facts so far:
- it doesn't seem to be leaking from any gaskets (at idle speed) checked valve cover, sender, and head gaskets
- never see any puddles of oil on the ground after being parked
- no blue smoke out the back. theres a little white smoke, slightly more than there used to be but not that bad at all and could just be from the cold and wet weather. and it smells normal
- oil light comes on about every 2,000 miles or so now. before about 3 or 4 months ago it had never come on before, I would just change it every 3-5k miles regardless
- extra info: started out using 10w-40 then switched to 5w-30 then 5w-30 synth now 10w-30 synth (over the course of about 3 years)


here's whats happened and when in detail:

[07.15.06] 159,400 mi - oil and filter changed, everything normal

[08.20.06] 162,300 mi - oil and filter changed again, like normal

[09.01.06] 163,165 mi - first time I'd ever seen the oil light come on. was low but still clear, 1qt added

[09.16.06] 164,749 mi - oil and filter changed

[10.14.06] 166,853 mi - oil light on again. very low but still clear, 1qt added

[11.02.06] 168,262 mi - oil light on. switch to Mobil 1 full synth 5W-30, changed oil and filter

[11.26.06] 170,000 mi - oil light on. added 1qt Shell 10W-40 synth blend, its all I could get and I had a long drive home

[11.30.06] 170,748 mi - oil and filter changed. switch to 10W-30, still Mobil1 full synth

[12.18.06] 172,370 mi - oil light on. change oil and filter

[01.04.07] 173,800 mi - oil light on. found oil leaking from drain plug, tightened it and put it 3qt Mobil1. ran car for about an hour, no more leaking from plug

[01.07.07] 173,900 mi - still no leak from drain plug. added engine oil tracer dye, will check it in a few days



thats where I am now. throw out any ideas you might have and I'll either try it or tell you I've already tried.

I wish my car would get that much life on oil. My car was getting around 400 miles on a full tank of oil and then a couple weeks ago it was getting like 133. As I type this it is in the shop having an engine put into it. So be greatful that it gets that much. For last couple of weeks it would putting oil all of the passenger's side of the car and the rear.

I was trying to make it last til Summer so I could do a V6 swap, but I don't have the time or the money to do it right now so I'm having the same type engine put in it. Atleast I should have a brand new car basicly after it is done. They are putting in a refurbished engine with 0 miles on it in my car .
