Fairtax4me Posted January 21, 2011 Share Posted January 21, 2011 Separator plate leak sounds plausible. You can't tell if that's it without pulling the engine though. It could be that or the rear main, and inspection of either is pretty difficult with the engine mated to the trans. Did you wipe some on your finger to see what color it is? Anything wet with oil in front of that area? Quote Link to comment Share on other sites More sharing options...
davebugs Posted January 21, 2011 Share Posted January 21, 2011 Odds are very good its te oil seperator plate. Unless someone has already pulled the engine or trans to fix it. And you can often tell that by looking at eng/trans bolts, or simply where the eng/trans meet - if it has never been disturbed. Heck - I even scotch brite then anti-seize the mating surfaces. If the oil gets on the Y pipe at the Y the odds are really good. Quote Link to comment Share on other sites More sharing options...
Suba9792 Posted January 21, 2011 Share Posted January 21, 2011 Mine was leaking pretty bad, be sure to loctite the screws on the aluminum one. and while your down there clean it up with some brushes, solvent, a flat razor for the mating surfaces and some elbow grease. The aluminum one I received for free:brow: another guy was tearing down a 25d at GDs and it was on there! he just gave it to me, don't think he realized its $37 at the dealer ahahhahahaha mine now. But it was much appreciated. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted January 21, 2011 Share Posted January 21, 2011 Well - to be fair (Mike) your's is the "stock" aluminium one - the replacement one's are steel and are even better. But both are fine and are infinitely better than the plastic one's that always leak. The benefit to the steel one is mostly that the screws can be easily removed and the plate resealed. Those pesky phillips head bolts on the aluminium plate are hard to remove without an impact screwdriver. Sounds like a pretty sure bet that your leak is the sep. plate. I've never pulled an engine with a plastic seperator that *wasn't* leaking. GD Quote Link to comment Share on other sites More sharing options...
Suba9792 Posted January 21, 2011 Share Posted January 21, 2011 crazy, I didn't know the aftermarket ones were steel! I thought the aluminum ones are the aftermarket hahhaha that is good info for the future. Quote Link to comment Share on other sites More sharing options...
987687 Posted January 21, 2011 Share Posted January 21, 2011 The guy who helped me with my clutch said that since my plastic one wasn't leaking it was fine... 25k miles later no at 119k I'm worried about the stupid thing and dreading pulling my engine back out. Live and learn........ Quote Link to comment Share on other sites More sharing options...
Suba9792 Posted January 22, 2011 Share Posted January 22, 2011 if you have a 5mt just do it at the next clutch job if its not leaking bad. Quote Link to comment Share on other sites More sharing options...
987687 Posted January 22, 2011 Share Posted January 22, 2011 I dunno if it's leaking or not... But I don't want to pull the engine out again. My clutch shouldn't dye anytime soon... Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted January 22, 2011 Share Posted January 22, 2011 I dunno if it's leaking or not... But I don't want to pull the engine out again. My clutch shouldn't dye anytime soon... then keep oil on hand and check it often. Quote Link to comment Share on other sites More sharing options...
Mugs Posted January 22, 2011 Share Posted January 22, 2011 Yes the "aftermarket" or update kit you buy from the dealer to replace the plastic ones are metal and should come with allen head bolts and not phillips. Just make sure you don't put the allen head bolts in the factory aluminum one, the heads will rub on the flexplate and make an awful "oh crap what the hell did I just screw up" noise. Trust me I know. :-\ crazy, I didn't know the aftermarket ones were steel! I thought the aluminum ones are the aftermarket hahhaha that is good info for the future.
