carl0s Posted October 16, 2008 Share Posted October 16, 2008 I seem to have an oil leak on the Supra. I'm fairly confident that it has only appeared since I last changed the oil & filter. Is it therefore reasonable to think that I might not have the filter on tight enough? I try to do it pretty tight (using marigolds), but not so tight that it'll be awkward to take off next time. It's possible that I didn't have marigolds to hand and used something less grippy when I did it, I can't remember. Is this at all likely, or does the oil system not work like that. i.e. if it was leaking around the filter, would I have had no pressure and catastrophic engine failure by now? Oil/filter change was done over a month, maybe six weeks ago. I tightened the cam covers a while back, so it's unlikely to be that. Evidence of leak is small patch on driveway. Any ideas? Thanks!

supra_si Posted October 16, 2008 Share Posted October 16, 2008 was probably a loose filter, they are the most awkward damn thing to hand tighten. mebbe worth getting under and trying to do it up some more with bare hands Link to comment Share on other sites More sharing options...

supra_si Posted October 16, 2008 Share Posted October 16, 2008 at least whilst under the car you should be able to trace where its dripping from if it turns out not from the filter, but i hope it is for you Link to comment Share on other sites More sharing options...
Luka-P Posted October 16, 2008 Share Posted October 16, 2008 Have you cleaned the patch and checked to see if it reappears? May just be excess from the filter change when you took it off. Just a thought. Link to comment Share on other sites More sharing options...

Just a thought. That's exactly what I thought for the first few weeks But I'm certain it's fresh now. Link to comment Share on other sites More sharing options...

supra_si Posted October 17, 2008 Share Posted October 17, 2008 have you had a look yet fella?? Link to comment Share on other sites More sharing options...
carl0s Posted October 18, 2008 Author Share Posted October 18, 2008 have you had a look yet fella?? Not had chance to have a look yet mate, but I think I will do it today if it's not raining. It's always a bit of a PITA though as I have to use a jack/stands/groundsheet etc. Link to comment Share on other sites More sharing options...
carl0s Posted October 21, 2008 Author Share Posted October 21, 2008 Just been and had a look. It's definitely coming out where the filter joins the engine/whatever, underneath. It felt tight enough to me, but I was able to go another half turn.. Let's see what happens. The car is currently on a slight incline (nose up), due to the driveway, and having been sat idle for a couple of hours, the oil level is reading high, i.e. on/maybe a bit above the second dot. But when I checked it last week just after a run on a flat piece of road, it was in-between the two dots, which I thought was good. Could my oil level be high? Could high oil level cause higher pressure and therefore a leak where there otherwise wouldn't be one? Link to comment Share on other sites More sharing options...
carl0s Posted October 21, 2008 Author Share Posted October 21, 2008 Actually, can't be pressure I wouldn't think. The oil looks to be leaking out overnight/weekend whilst the car is parked. Link to comment Share on other sites More sharing options...
supra_si Posted October 21, 2008 Share Posted October 21, 2008 has the extra half turn worked? Link to comment Share on other sites More sharing options...
