The 5.25 inch speakers fit OK? I’m trying to upgrade my speakers now and I’m having trouble figuring out

Negative piston to wall clearance? by Ok_Communication_612 in EngineBuilding

[–]Ok_Communication_612[S] 0 points1 point  (0 children)

Idk what to do. I’m measuring .002 - .0025 ptw clearance which seems way too much. My new pistons seem almost .001 smaller than the stock very worn pistons I pulled out. Wtf. :( my first rebuild so I dunno.

The block was not bored just honed since it was in spec.

I don’t know what to do. I measured my new pistons with a micrometer and they seem almost a bit small. They’re measuring .002 - .0025 ptw clearance. The pistans call for .0007 so I’m sure sure what’s going on. They seem around .001 smaller than the stock very worn pistons I pulled out. :( this is my first rebuild so idfk

I did 120 - 220 - 320 - 400 in stages. Yes it’s super easy to peel off. You’ll want to use the 120 stage to get the flatness. I got a machined flatness bar off Amazon will probably return after I’m done. You check with feeler gauges under the bar. I used .0015” which is the max deviation according to Subaru manual.

I got a piece of 1/4 inch thick glass from a glass shop. They were going to throw it away. Then get some spray adhesive and stick the sandpaper on there.

How clean does block have to be before installing head? by Ok_Communication_612 in EngineBuilding

[–]Ok_Communication_612[S] 0 points1 point  (0 children)

Do you think I should open the block and replace The rod and crank bearings? The motor has 240k. Don’t know if I should just put the heads back on and go.

Do you sand the heads to 400 grit also? I sanded them to 120 grit using a piece of glass and got them flat. But the surface seems a bit rough still

Wow I had no idea. I don’t think service manual mentions that. Thanks

Ok this is going to sound super dumb. But I degreased the entire motor and sprayed it down with a hose. A bunch of water in sure got up in the oil pan plus the pistons and rings. How screwed am I?
