Try a two stage fuel cleaner. First try a cleaner that raises combustion
temps so you can get the carbon outta there. The use another type that
actually "cleans" the injectors. DO NOT attempt to clean the pistons now.
Carbon can get down between the grooves and rings and before too long,
your back into it to replace rings.

It is possible, but it'll probably be easiest if you either have a friend
to pull the joints outta the way, or install the block and THEN the
transmission. Wedging them both in there at the same time may prove to be
a problem. The exhaust manifold may be a bigger hassle than you think
too.

The passenger side motor mount! Clutch! Rear main seal! Front seals (3 +
'O' ring)! T-belt & tensioner!

I doubt you'll find a site explaining the swap in enough detail for you
pick out what steps you want to follow. One thing you may not have
known...knock the alignment dowel out of the 2.0 block on the drivers
side so you can fit the 1.8 head on it. You'll have to use the remaining
dowel and a head bolt on the opposite side to align the two to the
gasket.

Depending on your rpm's at the time of the break, there's a chance you'll
find nothing.
