bgd73 Posted September 19, 2006 Share Posted September 19, 2006 I went through half quart of oil in 200 miles, I should be smokin like an exterminator. but I wasn't. So I checked oil pan bolts, cam casing, valve covers. It was soaked to the point of a drop waiting to happen of my new oil.They all took yet more tightening casually.the first go with this was several full turns on the oil pan bolts about 25k ago. They only took half/.75 turns now. I hope i am winning the old neglected gasket that was soaked due to loose bolts. I even thought the engine shrunk all parts after keeping it much cooler without egr, and better intake, and even vented the front grill/bumper.Does bad mains vibrate the engine apart? Or am I overthinking.... Link to comment Share on other sites More sharing options...
northguy Posted September 19, 2006 Share Posted September 19, 2006 Try some Locktite, but don't use the red. Link to comment Share on other sites More sharing options...
idosubaru Posted September 19, 2006 Share Posted September 19, 2006 where's the leak coming from? all of the bolts are loose or just some? if the bolts are corroded, dirty or the holes are dirty they may "tigthen" but the threads (bolt and holes) need to be clean to get a proper torque.

bgd73 Posted September 20, 2006 Author Share Posted September 20, 2006 they are slicked up from leaks. The valve cover bolts stay tight the longest (rubber grommet). The oil pan could be conquered now, if not, I will use some lock tite of some sort. The cam casings tighten with a "crak" noise, leading me to believe the engine really did change density... It does happen, even on cast iron blocks (in Maine anyway).Aluminum is very responsive to thermal, regardless of how tough they made it. Thanks for replies..

GeneralDisorder Posted September 20, 2006 Share Posted September 20, 2006 The cheap oil pan gaskets do that. They soak up the oil, and then the bolt pressure gradually "splits" the gasket in half with the center ridge of the pan. Your bolts are not getting "loose", but rather the gasket is getting thinner. I had one of the cheap cork models do that, and as I gradually tightened the bolts over a period of weeks, eventually the gasket just split in half completely and part of it just fell out the side. Dealer only for those pan gaskets. They are cork as well, but are already compressed, and have a coating on them. Prepare the new gasket by coating with a thin layer of RTV, and allowing it to dry before installation. GD Link to comment Share on other sites More sharing options...
ShawnW Posted September 20, 2006 Share Posted September 20, 2006 Or just RTV instead. All the new engines use it so why not the old I say. Link to comment Share on other sites More sharing options...

The fundamental problem with *just* RTV, is the shape of the pan lip. It's got ridges at certain intervals. The newer pans are aluminium, and the lip is flatter.

Phizinza Posted September 20, 2006 Share Posted September 20, 2006 I found once these gaskets start leaking that don't stop if you just tighten them up. They need full cleaning/replacement. The oil seems to stop them from sealing. Just my experience anyhow. I used RTV, works better then most sealants. Link to comment Share on other sites More sharing options...

I learned this on older cars with same crappy cork rubber. they either disintegrate or petrify perfectly. They all needed retightening.As long as nothings missing, I am at petrified/chunking stage. There is still some squish, I have no worries just yet about failure.The tighter it gets, the less chance anyway. I like the steel dome of an oil pan on this engine, for reasons I don't even want to babble.As long as that has no dents. Link to comment Share on other sites More sharing options...
