Oil Burn at Startup
Posted 08 December 2006 - 12:42 AM
This is typically valve stem seals, right? As long as I top it off with oil, it should be fine? If that's the case, I'll just keep the oil topped off and drive it.
Could it be the ATF? I've heard the ATs can cause the engine to burn ATF, not sure when or how. But could this be it?
Could it be the turbo? Not sure when turbos can cause an engine to burn oil.
Kinda hoping its not valve stem seals, as I can change the rest easier. If its valve stem seals, that required removal of the heads, right? Can I do it myself, or is this something better left to a machine shop?

What about, a rope in the cylinder? If I turned the engine to the compression stroke of each piston before I removed the valve seals, wouldn't the valve up?
How do I remove the valve stem seal?

Valve stem seals are the easiest and cheapest of your possible repairs. ATF burns whitish-grey and STINKS, so probably not that. The turbo seals are another possibility, especially if you don't let the car idle down for at least 30seconds before shutting down, if it gets lugged at low rpms for extended periods, or has been overheated at all. This is especially an issue on the earlier non-water cooled turbos, since their cooling came from the oil.
The most likely cause, though, is rings. These engines, with their horizontal configuration, don't always follow the conventional causes of oil consumption. Pull the spark plugs, and look into the cylinders. If you can see oil in there, then it's a ring problem. Also, if you are now parking on a sideways slope, try parking so the car sits level side-to-side, since there won't be as much gravity assisting the oil to get past the rings.

it shouldn't hurt things in the short run to drive it like that, but in the long run it would be a good idea to get your heads rebuilt

No kidding. I should just stop using cars all together.

If you use a rope, use one that isn't much smaller than the plug hole or it will knot up in the cylinder some how and you'll really get mad! Also soak the rope in motor oil first.

Strange thing, this morning it did not do it, though its been a warmer morning than the last couple days.
I changed the oil today, put a quart of MMO in it, ran it for 5 miles, and changed the oil again. We'll see if it does anymore.

I just bought the car, so dunno if it did it during the summer. It should also be known that this car sat for quite a long time being driven like maybe three times in the past year+.
What weight of oil do you use? Did it do this in the summer?
I don't know what weight of oil was in it before, but I put in 10W-40.

Hasn't done it since I changed the oil, so I'm just gonna shrug it off until it starts happening again.

I have to say that I can't believe the SeaFoam hurt the rings in an engine. I have used it in the crankcase of at least 6 vehicles and have never had a problem. And I leave it in untill the next oil change, although it has been said that it will evaporate of after a while. I think that engine had other issues.
