I'm trying to get my pistons out, haynes manual says to use a ridge reamer and get rid of the little roughness 1/4 inch down the cylinder wall, is this necessary?

Also, how do I take the main bearing cap off? I've loosened the 8 14mm bolts and it's not budging at all

 

take a rubber mallet to it and give it a few taps to loosen it. Pistons push up and out through the deck where the head gets mounted.

 

x2....main caps are on pretty good, just give em a light tap with a soft mallet, should budge loose...

 

Sweet got that off, you guys see the dark brown tinge everywhere? It's like a thick coating of oil or something, is it a problem if I don't clean it out? Or will it melt off or something once I drive the engine?

 

I pressure washed all my parts with engine degreaser, you just need to make sure to lube it all back up when putting it back together.

 

no pressure washer here. i scrubbed for half a day before someone said use gasoline, that worked beautifully

 

Don't use gasoline, I'm no environmentalist, but that **** leaves a mess... Take the parts to your local do it yourself car wash, and pressure wash them there. But don't use gasoline, stupidest **** ever, my friend told me that before, and I told him he's ****ing stupid...

 

ooh ok. Pressure wash will get it all off? My friends got a pressure washer I could probably borrow, but what's wrong with gasoline? I have a bin that I clean the parts in, have like 2 in thick of gasoline on the bottom, and dip the scrubber in every time I clean it

 

I mean if you have a bin that you do it in then it's no biggie, you have to remember there is also oil in gasoline, and when that gets all over the place, it's a big mess... Once you get the motor back together you will have gasoline oil mixing with everything, because you will have coated all of your parts with it.
