Have a 97 with 173k that stall last night. I was able to get it started a couple of times to limp home a few blocks. Engines been burning oil approx 1 guart in 4-500 miles. Kept up with that and had replaced exhaust from manifold out the back. At 7k after exhaust done one cat clogged and had little power blew hose off EGR valve. Mech got it replaced under warranty we know it’s from oil. I’ve been trying to limit use until I find another rig but may have run out time. Any thoughts on stalling? Happened yesterday so can’t call mech until Monday. Want to know what I’m in for hoping only have to rebuild top of engine. Thanks
