Good idea trueing up the cylinder base. Use the sls base gasket along with the mls head gasket. Use cometic torque specs/procedure. Lube the stud threads as mentioned earlier and lube the underside of the head bolts. Use new head bolts. If the studs feel tight, don't mess with them.

 

Started back putting the front cylinder back on. Pushed it down and it seemed hung up about 3/4 of the way. Pull cylinder up to see what issue might be and...pulled cylinder off the piston. My dumbest error.

IIRC, I can't reinstall what I have.

I need new rings and the cylinder honed, I believe. Anything else so I can keep my f***ups to a minimum.

 

**** happens. Some say yes re-hone and re-ring, and some say no. I would hold off till you get more info/feedback from the more experienced guys on here.

EDIT: Does one of those stud threads (the pic on the right) look a little galled?

 

The current rings will likely be as good as they were before the tear down, but it's lot of work to go back in later. If it were mine, at 50k miles, I'd mic the cylinders and re-ring and do a valve job with new valve stem seals.

Follow the Cometic procedure for torquing the head bolts. And lube (lighty) the head bolts (flange and threads).

You can reinstall with no issues, just make sure the end gaps are 90 degrees apart and not facing forward or backward on the thrust faces.

There is no reason to re-ring and re-hone just because you pulled a jug by accident...many will tell you otherwise but they are just plain wrong.

 

If you did not destroy the rings,


Then split ring band clamp to re-compress the rings to the pistons, to get the the piston back in jugs.

Also, if you want to pull the jugs off, then should be easy to put the ring gaps back to where they where first placed as well.

Make sure your gaps are lined up and go for it

Been there done that

The piston was not originally removed from the cylinder when the head, cylinder, etc. were removed.

I just pulled the cylinder off...would the rings have moved just from this action? I understand it's probably a good idea to check.

Thanks for the heads up on the tool for the rings.

 

If the pistons camer out of the cylinders, mabey, It's like so many other small details It's worth checking to be sure.

I wouldn't re-ring or re-hone unless you had blowby/low compression issues prior to the teardown. Check the rings for damage, check the cylinders for scrapes, remove any carbon deposits, go ahead and reinstall. Well, mic the cylinders first and see if its necessary to bore out +.005, if not then reinstall. Note that the cylinders deform as much as .003" when torqued down properly so there's your margin, if you want to be **** about it use torque plates then measure. Or have a reputable machine shop measure for you
