killshee Posted March 18, 2009 Author Report Posted March 18, 2009 i was using a stock gasket and stock head and it started leaking on the right side. then i went to the cool head with o-rings and same side. the o-rings aren't braking, the right side just keeps leaking. the squish seems right to me. "average" is there anyway to fix this? would it hurt to try high temp sealer around the o-rings? im gunna guess my cylinder is bad. witch would mean that i need a new one right? or is there a way to fix it?

dajogejr Posted March 18, 2009 Report Posted March 18, 2009 You'll need to surface plate both cylinders....and possibly the head now that you've tightened it down and used it. Remove the cylinders, remove the head studs. You need a flat, FLAT surface and some nice 200 grit wet/dry sand paper. Move the top of the cylinder into a figure 8 motion until you can no longer see any "unscratched" surface on the gasket surface. Do the other one next. Then take the water neck off the head, take the domes out...and run it a few times in a figure 8 motion, make sure the sand paper is "scratching" the entire sealing surface. It happens... Quote

bbcmudtruck Posted March 18, 2009 Report Posted March 18, 2009 It shows you how to do this in the manual as well. Quote
blowit Posted March 18, 2009 Report Posted March 18, 2009 should i put them side by side and go figure eight across them both? this is what u ment right? Is the cylinder deck messed up? What is very common in what you are describing is people will not install the locating dowels on the bottom of the cylinders and they will not align right with the head and when you torque the head bolts, the head will pull the cylinders out of whack and cause a leak. It is more common with base gasket leaks though. I would also want to check the length of each barrel and figure out if one is longer than another. .001" should be OK but much more than that can be a problem. As D mentioned, if you already torqued down on the head, you may have tweaked it a bit. I would surface very carefully to reveille any high spots that could be causing problems. What is leaking and where from? Brandon Quote
