a brass brush and some acetone will remove all the carbon on your pistons without any damage
really i was afraid it would damage them somehow i want to clean them the best as possible is acetone safe to use on them or block over all?
use super clean
I personally use a can of brake clean and a plastic bristle brush.
Bring the piston to TDC, spray a couple shots.. scrub, repeat.
How does the whole torquing down at degrees work? I am stuck at this I cleaned up the pistons and heads even more and am wondering how to do this they are mounted on the block but idk how to do it at degrees I just thought it was a pattern on which bolt to do first second and so on and a certain ft of tq.
You need a torque angle gauge.
They sell them at Advance and Autozone for about $6.
Call me crazy, but... 37 pounds plus 120 degrees would be 37 pounds plus 1/3 of a turn. (120* being 1/3 of 360* or 1/3 of a full rotation).
Or... Torque for a 7/16ths grade 8 oiled bolt is right at 60 lbs.......75 dry.
Go get your 5th grade protractor that you had with you every day. Follow the angles, there ya go. 90 degrees is a quarter turn, 120 is a third as mentioned, 180 is a half turn.
To go with the rotating angle thing, grab a silver sharpie and mark the head of the bolt if it helps you keep track of how far you turn them. If you mark them all at 12 O'clock before rotating them to the proper degree the marks should all end up in sync with each other.
Ohh I just put the ratchet at say 12 or 3 and go from there to my angle.
so just mark them all at 12 to keep track of them start at 12 or 3 and torque to 37? correct? hopefully i can do this today
torque to 37... then decide how you are going to torque the angle. You need 1/3 of a full turn. Me, I can't see through my socket, so putting a mark on the bolt...doesn't tell me where to stop unless I go in small increments. Which might stretch the bolt oddly.
I therefore Put my handle of my ratchet at say 12 o'clock and I go a third of a turn....aka about 4 o'clock. Done.. next bolt.
so i torque them down to 37 doesnt matter how but just torque them all down to 37 then from there say 12 a clock to 4 at what torque do finish since they will already be torqued at 37?Quote:

Remove the socket from the torque wrench and put the torque wrench away 'cause you won't need it anymore.
Attach $6 worth of angle tool to a breaker bar - socket on other end.
Set angle gauge to 0 degrees.
Use a buddy or some wire to hold gauge. I use my magnetic base for this...doubt you have one.
Tighten each bolt (mind the sequence) in one motion until the angle gauge reads 120 degrees.
Congrats; you have stretched each bolt according to specification.
