Play in the Crankshaft? Time to Replace Engine Bearings?
With the flywheel and clutch installed I have some play when move the crankshaft up and down.
This is on a .12 sirio evo4 sti engine with about 1.5 gallons of 20% through it. This engine has ceramic rear bearings and steel front bearings. It seems to have more play then my novarossi 12-3sct plus that has the same mileage.
The crankshaft rides on bearings so I imagine that I might have to consider replacing something soon? Would it be the front or rear bearing? The engine runs ok right now, is it that critical?
Someone who hear my engine running pointed out that it sounded different, so he applied pressure to the heatsink and the tone changed. He told me this means the rear bearing is worn. He did this before I even noticed the play in the crankshaft.

I've never heard of people replacing bears because of what I described. I have only heard of replacing bears because of a "gritty" feeling or the front bearing leaking fuel. Which is why I wanted to ask.
