Bosch 261 200 175

This was my spare, until the car jumped time, and bent every intake valve.  Sold the car.  $50 shipped to your door.

The car is going to be parted out.  I bought it cheap with the motor issue...so I'm just going to recover the costs, and send the rest to the yard...I listed the car whole on R3V.  I hate to throw away a nice non sunroof E30, but I need to get the money out of it.

I pulled the head tonight....all intake valves bent, and 8 exhaust valves.  Car appeared to be timed correctly...who knows what happened.  It's going up for sale..or getting parted out...

I've got an M42 that went dead while driving down the highway.  No noise, no smoke...just shut off.   The car cranks but sounds like it's spinning freely...like there is no compression.  Put 2 different compression testers on it and it shows zero compression.  How is this possible?  I pulled the valve cover off..cams look good, timing chain looks fine.  Cranked it over using a large wrench and at TDC, the cams and crank appear to be timed correctly.  Even if they were off by a tooth, I would still expect some compression somewhere in the cranking cycle.

Other interesting notes.  I took out all the plugs.  I used my air compressor to pressurize cylinder 1.  When pressurized, the air came back out of the spark plug hole for cylinder 3.  Seems pretty strange to me.  

Car has fuel and spark, but with zero compression....well...the internal combustion just won't fly.

I'm baffled..Any thoughts or ideas would be greatly appreciated.
