Sorta the same story.

About 5 years ago, I started burning about a qt every 1200-1500 miles. Had the valve stem seals replaced then.(at 75,000) Now, I don't need to add any between changes. 3000-3500 miles. No other top end work

Before I bought it in 2001 (with 41k then) I had a PPI done and the MB dealer (Lokey in Tampa) said it needed a head gasket as there was an oil leak at the left rear. The seller and I split the cost.

She doesn't leak or burn at all today.

I've read here, and I believe it, that the bottom end of the 103 is darn near bulletproof. The valve and guides will wear because of cam design & lash. The timing chain design lends itself to longer life that a 104.

I still have the original water pump. New radiator this year. New exhaust last year. Original cats still aboard. Fuel system still original, except the fuel pump relay went last month.
