91 EX accord 5 speed, around 130k miles- OIL BURN

91 EX accord 5 speed, around 130k miles. Every 2 tanks of gas, I have
to add about 1 quart of oil into the engine. I have no idea where the
oil go.

Recent replaced: (have used air intake)
1. 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? )
2. Replaced a used PCV valve. (almost 2 yr ago from yunk yard).
3. O2 sensor. (because engine light ON about 3 months ago).
4. 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)
5. New distributor ( Oil leak and went through the seal).
6. Timing looks ok at about 15 + 2 ( spect is 15 +/-- 2). No valve
knocking at all.
7. Just a litle white smoke when start up (at about 60 F) in the
morning.
8. Oil change every 3000-5000 mils depend on how fast the oil getting
dirty (use BLEND oil which is part of synthetic).
9. 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.

 

We used to see a lot of these reports, and not a lot of them were resolved.
I think most or all those that were resolved turned out to be broken piston
rings. The catalytic converter burned the smoke and kept the exhaust looking
clean.

Unless you know *for sure* the timing belt was replaced about the time you
bought the car, do that immediately. It is well past due in terms of miles
and way past due in terms of years. You are lucky the engine has not been
destroyed by timing belt failure yet.

-----------------------------

PCV that's stuck open will suck your oil out invisibly, and burn it in
the combustion chamber. An OEM Honda PCV isn't that expensive. If it's
the cause, you've probably paid for a new one twenty times over. A bad
thermostat could have hacked up your rings too, if left uncorrected for
too long. Engine has a 'sweet spot' for temperature. When you operate
outside that (or let your car warm up in winter) you increase wear
dramatically.

Also make sure there is no oil in your radiator fluid (head gasket,
cracked head). Do a compression check to eliminate the possibility of
a big internal problem (rings, valves, head gasket) before you start
putting much money in. A problem here could change the situation
drastically.

 

If you mixed the exhaust and intake seals then maybe they have worn
again prematurely, the white(blue) smoke on start up is usually a sign
of worn seals.
Had the same problem on my 91 Accord but not as severe.
