Just wanted to make sure you did not feel put-upon or taken for granted.

Pull the heads to diagnose the failure.  Save the heads for the parts barn if they aren't cracked.
Pull the 87 timing cover and save.  Parts Barn or any member
Pull the 87 oil pan and save.  Parts Barn or any member.
Pull the lower intake and save.  Parts Barn or any member. 

I think there was a head gasket failure and none of the hard stuff is damaged.  It would be a good engine for a bore and stroke if there's no physical damage to anything.  Otherwise the short block goes to the yard.

The inside of the engine and the good side. 


The inside of the engine and the bad side. We could find no clear indication of a blown head gasket nor a leaky lower intake gasket.  However, this side was the side where the problem occurred.  Notice the washed piston crowns?  This side also had a slight amount of surface rust on the cylinder walls. 


We also pulled the timing cover to see if there had been a leak there, but even so, there would have been no coolant in the combustion chambers.

I wonder if there is a crack in the block or head. I know that can happen on a duke -- how about the 2.8? A crack can be very hard to see to the untrained eye. There was a crack in the old had of my duke, which the shop I took it to found. That's why I got another head for it back when I rebuilt it.

Surprisingly, the block appears to be a very serviceable block.  The cylinder walls exhibit very little wear, witnessed by the lack of a ridge at the top of the cylinder wall.  This engine could probably be salvaged with a crank kit, new cam bearings and cam. 

We didn't examine the heads closely, but I think that it would be on only 1 cylinder.  This appears to be on the full bank of cylinders.

Did all of the head bolts come out in one piece? Were any noticeably stretched?
But I agree with you. No obvious evidence of a leak. The steam-cleaned piston crowns are telling, though.
I might suspect a head crack between those two cylinders. (Or was it all three?)

Charlie can say more about this, but the head bolts weren't as tight on the side with the steam cleaned pistons.

Maybe they just weren't tight enough.  It would seem that combustion would have blown the gaskets, though.

On the good side, it took a little hammering of the impact to break them loose.  Like Pat said, all the bad side bolts spun loose on the first trigger pull.  But there's just no indication of a coolant leak on either the block or head.  It did span across all 3 cylinders.  The 1 and 3 had slight rust on the cylinder wall but 5 was at the top of it's stroke, and no rust was showing. 

This would have been a factory engine with somewhere just over 100K miles on it.  It came from Bbristow's 87.  I don't think the engine had ever been torn into.

I put new tires on the 86 some time back so that it could become my daily runabout car.  Next morning it wouldn't start.  No fuel pressure. 

I later ordered an Airtex fuel pump and last week had a local shop install it.  No good.  It wouldn't run.  Can't get a refund, only a replacement, after I send back the defective one and they examine and determine if it's bad, or not.  So, I had the local shop order another brand and install it.  It runs.  Got the car home and heard a noise in the engine bay.  The brand new water pump we installed less than 100 miles ago is grinding and leaking.  So, now it, along with the 87, is parked for time unknown.

Does this mean you have no running Fiero?
