My 90 (5.8 EFI) is eating oil....leaks a bit but I am eating a quart every 5 days or so. But I don't have smoking (other than right after start up). Where the hell is it going?

I'm a rookie here....what will they see?Larston said:If you have smoke on startup, you have worn exhaust valve guides. You can pull a huge amount of oil past the guides and never see smoke from inside the vehicle unless conditions are just right. The best way to check is to have someone follow you as you coast down a long hill. If the guides ARE bad, it'll be pretty evident.
When the exhaust valve guides wear out, you can draw oil through them on deceleration due to vacuum in the exhaust ports. If you hit the top of the hill at 50mph or so and downshift into second, the exhaust will start blowing blue smoke after a couple seconds. If you're losing that much oil, it should make quite a cloud.pjmorgan22 said:I'm a rookie here....what will they see?
