Recent replaced: (have used air intake)
- Did replaced the valve steam seal myself 4 years ago after awhile bought the car at 78000 mils (can intake and exhaust steam seal mix together? )
- Replaced a used PCV valve. (almost 2 yr ago from yunk yard).
- O2 sensor. (because engine light ON about 3 months ago).
- New spark plugs ( checked and saw NO oil on spark plugs for a month, a litle gray+white deposite on spark plugs, to me this is kind of normal)
- New distributor ( Oil leak and went through the seal).
- Timing looks ok at about 15 + 2 ( spect is 15 +/-- 2). No valve knocking at all.
- Just a litle white smoke when start up (at about 60 F) in the morning.
- Oil change every 3000-5000 mils depend on how fast the oil getting dirty (use BLEND oil which is part of synthetic).
- Will replace timing belt at around 150-160k mils.
I am not sure if the leaks still from the crankshaft and camshaft end seals because I had it fixed at a store about 3 yrs ago, but don't see any oil leaking. (not open the timing belt cover, I mean just generally looking when open the hood). If yes.......is that possible for 2 gas tanks/ about 1 quart oil need to be added ????? I don't see any droping oil at all from the engine.
Any one had this problem/ or know about this, please help. I really appreciate it.
