I swapped a 3.0 m103 into my 190e so I will not be needing the 2.6 anymore. Has 220k miles, head gasket was done 30k ago. Since I've had the car for the last two years most of the driving was highway, commuting to work and back. Compression is around 150 psi on all six cylinders if I remember correctly, last time I tested it was around a year ago. Valve stem seals were all done 10k ago, burns/leaks a quart every 1500-2000 miles. For some reason the motor pulled harder than two other 190e 2.6's I've driven, never sure why because all specs matched (timing, vacuum, compression, etc).
This is only for the block, head and waterpump (and internals of course). Valve cover, ps pump, ac compressor, alternator, smog pump, intake manifold, exhaust manifold, belt tensioner and fan clutch have all been removed to go on my spare parts shelf for now.
Oil pan is included but you will probably want to replace it. The drain plug is completely stripped so I had to drill a hole to drain the oil. This oil pan was actually on the 3.0, I had to swap the good 2.6 oil pan onto the 3.0 and vice versa.
Here is the only picture I have of it out of the car, I'll have to take more pictures later.
Local pickup only in Southern Orange County, CA. San Juan Capistrano to be exact. I have an engine hoist to load it into a pickup.
$200 OBO, need to get it out of my garage.
