LaegerEliminator Posted May 2, 2011 Report Share Posted May 2, 2011 So I am beggining to reassemble my topend. I was told by motor builder to pour some cleaning solvent into the bottom end and then dump out to give the bottom end a cleaning. After filling both crank case sides full, I noticed that I am losing solvent out the clutch side case. When I removed the tranny drain bolt, solvent came out. The flywheel side is not losing any solvent. Is this a problem? I am thinking this isn't going to pass a leak down test and that I have seal issues in my bottom end? Thanks Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted May 2, 2011 Report Share Posted May 2, 2011 your first problem started with dumping anything down the crank,hope its not rusting up as we speak,second your cranks seals are gone now,cleaners will destroy seals Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted May 2, 2011 Report Share Posted May 2, 2011 Sounds like time to split the cases! What exactly did you pour into your crank? The only things I would ever consider pouring in there would be gasoline, methanol, 2-stoke oil, or carb cleaner. Quote Link to comment Share on other sites More sharing options...
LaegerEliminator Posted May 2, 2011 Author Report Share Posted May 2, 2011 I am not sure what the exact fluid is, just a standard parts cleaning solvent. I use it in my parts washing tank/station. I purchase it from a local shop that carries it in bulk. I will get the details from the shop owner tomorrow. I had purchased new, clean fluid for the task. I am pretty sure I had a seal issue prior to pouring in the solvent, the loss was almost immediate upon pouring in the fluid. I removed the clutch cover and found the fluid leaking from the clutch side main seal. I was in the process of reassembling the top end since I just purchased new pistons and had the cylinders bored. I noticed a lot of carbon build up in the clutch side case. The motor seemed to run fine before I tore it down. Could this be an indication that something was not right?

bigblockbanshee Posted May 2, 2011 Report Share Posted May 2, 2011 Just tear it down and give it a good check-out while you're doing the top side. It won't be that much more work and you will be glad you did in the long run. There's nothing like trashing a brand new top end because something was wrong down below that you either ignored or didn't see. Don't be that guy lol.
