85 eagle wagon

[kwkwest90]

I have an eagle thats in great shape cosmetically, but it runs like crap.

It's been puttin really bad for a little while now, and the oil light will come on when its cold occaisionally and everytime I take it on the highway.
I've had the rear main seal, the valve cover gasket, the oil pan gasket, and a new radiator put in and i still can't seem to get it running right.

It still has all the original parts including the plastic valve cover.
I was hoping to get some suggestions as to what my problem might be.
Any information would be greatly appreciated.

Gaskets don't change how a car runs.

Could you give us more info regarding the engine's performance.    Poor oil pressure readings, can be from a bad sender, not enough oil, oil too thin and/or a weak oil pump.   The easiest thing to try is too use 20W 50 oil to partially overcome old oil pump gears.  I am guessing you miight have some oil loss too with that plastic cover.

yea i've had to put about a quart of oil in between oil changes. i've been trying to find an inexpensive replacement for the valve cover. but everything ive found so far is about a hundred bucks.

its spitting and sputtering. it almost acts like its going to stall but then doesn't. ive had the oil sensor looked at and from what they could tell it wasn't leaking. its almost like it is an oil pressure issue. but the oil light only comes on after driving on the highway for about 10 mins.

Does the oil light come on when you are going down the highway or just when you come to a stop?
Have you tried using heavier oil as Iowa Eagle suggested. The oil pump and bearings are probably worn and not keeping the pressure up.
The most common cause of poor running is a vacuum leak in one of the hoses cracked or disconnected or plugged idle tubes in the carburetor.
It could also be the EGR valve is stuck and leaking internally or an ignition problem.

I can't resist this Kicker, what about a leaking intake gasket ?? or carb base gasket for that  matter..... : )

I know you meant the ones he replaced though

Correct. Haha
