burning oil... but how?

[TSI4Life]

Hi, my names Matt.

So my problem is my talon's burning oil. Its a 420a and I just swapped in the current engine. It was a carfax engine with 90k on it. So i put it in, drive it nice for a whole day and gradually push it harder. I didnt want to be to hard on the engine because the guy i bought it from said it sat for a couple of months. I replaced the valve cover gasket, oil pan gasket, water pump, and rear main seal. When I started it for the first time it was great. It was a very strong solid engine and I was very happy..... until it started to burn oil. Now here is where I need help. I need input from someone more experienced in the 420a group. Mods included exhaust, header, plugs, and wires; thats it. I did a wet and dry compression test because my first guess was rings. ...190psi across the board on both wet and dry. I was very happy considering i know that my rings are not bad, so that leaves the head. This engine came out of a 95 eclipse AUTOMATIC. My theory is ( considering one week its running amazing and the next its consuming oil) that since it came out of an automatic, that means it saw somewheres around 5500 to 6000 rpm's tops due to the automatic trans shifting. Mine, on the other hand, (atleast with me driving) has seen 7,000+ rpms and the rev limiter a few times. Anyways, my theory is that since it had only seen a certain rpm for 90,000 miles the wear markes on the valve guides and seals were pretty well set and I believe me putting this one up to 7,000+ did damage to the guides and seals. It's the only possible theory I can come up with since it hasnt gotten any slower (no loss of power) and I dont have a turbo to consume oil through. Any input on this theory would be greatly appreciated. Thanks

You more than likly need new valve seals as the seals on these cars suck to begin with. Since it sit for a while that meens they were sitting up there drying out and then when you started it up they just gave out. You can do this whith the engine in the car and the head still attached. this company has the tool to do it ( euroexportinc.com ) Also you will need a manual because you have to remove the timing belt and camshafts. however if you have never done this before just paysomeone who has or get a friend who has changed valve seals on a car with the head still on to help you.
