Hi there,
I have a 2001 Mazda SP20, or Protg5 I believe it is called in other countries.
Recently the car shot a piston through the block, big hole around the size of a tennis ball. So being a fairly mechanical person, having worked on lot's of V8's in my youth and the Mrs problematic VW Golf tranny issues more recently I brought an engine second hand and decided to get to work.
Given the transmission was in good order I decided to simply remove the engine, save lots of hassle... yeah right..
So I have got the exhaust manifold, intake manifold and all the surrounding cabling, alternator, AC etc. away from the engine, basically ready for me to pull up and out. Now I am at the coal face with a couple of engine mounts, a few tranny / engine bolts and the flywheel to torque converter bolts accessed behind the starter motor.
The issue I am now facing is that the engine is actually seized, I guess Chernobyl in barrel #4 was a big melt down.. well I am sure it was as there's bits of conrod and crap everywhere. The obvious issue here being that I need to rotate the crankshaft to remove the flywheel / torque converter nuts - which I can't do!
My ideas were:
* Try and remove the sump and drop the big ends from the crankshaft - didn't work because I can't take the base from the engine without being inside the tranny.
* Remove the camshafts, hope that that might loosen things up - didn't work.
So they only other ideas I have are (in order of preference):
* Try and remove the engine with the torque converter attached to the flywheel - does anyone know if this would work without removing the transmission from the car?
* Use oxyacetylene torch to cut the box from the engine - seems a bit extreme, I guess it could work.
* Remove the engine and transmission in one piece from the car and then pull the engine and flywheel in one piece - I really don't want to pull the box out if I can avoid it.
Does anyone have any bright ideas???????????
Thanks,
Terra
