its not a crazy all over the engine leak but this tiny little bubble that bubbles up after the engine gets hot, its in this picture and its actually located above where the fluid collected, in the seam up there.


any idea whats going on?

i'd guess that the valve cover gasket or the small gasket that sits under the valve cover attaching bolt (that is right above the drip there) has been compromised.

clean, replace, clean again, ride and then report.

Why am I picturing Marsellus Wallace sitting by the pool with his wife calmly saying into a cordless phone: "You ain't got no problem, Jules. I'm on the m*therf*cker. Go back in there, chill them ******* out and wait for the Wolf who should be coming directly"?

So the leak starts actually at the seam above that spot right where the bolt holds it together. I think it's probably an improperly torqued bolt or as greasy was saying a comprised bolt gasket.

That's probably the ticket!

Now for he job

Undo the rear suspension at the top or bottom, doesn't really matter. Get a rope and hoist the chassis up slightly, this will give you some more room to work with the valve cover.

Completely back of the bolts, the cover should slide right off. Inspect the gasket. Should be no cracks, crimps or anything. If all checks out dip the gasket in oil and re seat, ensuring the surface is completely flush.

Obviously if needs replacing, oil and sit the new gasket the sane way.

Now, torque the bolts evenly! You want to go in a criss cross fashion untill you're pretty tight. Once they feel snug, but not over tight, go round one more in a criss cross tightening each one by a further 90 degrees. This should bring you within spec.

If you have a torque wrench, same criss cross tightening but untill at correct value which is found in the owners manual under specifications if I remember rightly.

Might just take it in to get this done. Is it safe to drive till then? I put paper underneath and it isn't leaking when it's turned off.

Shame you're not in the UK. Would of happily done it for you!

Right, so you're only loosing it under pressure right? How much is leaving the sump? Have you been checking the dip stick?

If you're staying in tolerance on your oil level, and you're coolant is good there's no reason for it to be too big of a problem. You did mention your oil is old, which will be increasing wear so bare that in mind.

So I'd ride it to the shop to get fixed, but nothing more really for peace of mind. Would suck if you broke a ring due to bad oil. Worried to why it is leaking, hopefully the oil isn't breaking down and causing it due to excessive wear. But that's hard to tell.

If you're insisting on riding, do an oil change. Very very easy to do yourself if you'd like the instructions? Would save money at the shop too. [/quote][/list]

Oil just got changed a few days ago, it isn't leaking like nuts and the rest of the engine is pretty clean, I see some gross oil in there from the road (did a lot of rain riding, 3 downpours in a week, it was late out and no one was on the road so I laughed about it.)

But yeah other than that it runs fine with an occasional temperature change related hiccup that causes it to stall in bumper to bumper traffic(which I expect is a grody air filter or carb. It always starts back up and the battery is healthy too. And that only happens every two months. Happened once before so I'm wary of it now.(especially before 700 mile drive

But I think I'll bring it in for them to look at it again. I got 300$ left in my budget and I'm hoping it's just a loose bolt

About the overheating, you may want to check on your fan's function. Could be just a blown fuse or something along those lines.

its not overheating or anything! the fluids aren't leaking enough to have any major impact on the fluid levels, the coolant tank is between minimum and maximum fullness.


I wonder what made the bolt come loose though, I got a feeling its running around on old oil

no. no. at worst you've got a few inexpensive parts to replace and some pain in the ass labor. i'll post something of a tutorial up in a bit.

checked some other stuff today too, hub oil is at minimum but not low, and the engine oil, is right around max. could it be overfilled slightly and the oils just finding whatever way it can out?

unrelated, theres a little rattling noise whenever i come to a stop and decellerate to an idle, its not a constant but it comes and goes, is this urgent? i was gonna put off new cvt stuff till 9,000 exactly

Anyone got an idea on the cost of this? I got 400 dollars left and I could very well get the air filter and aome other things done as well. Was wondering that's enough. The mechanic charges 90 for labor (which is pretty good)

If your oil is in max, its perfectly fine. Sounds like its only leaking under pressure and by where its coming from its just the valve gasket. Probably not properly torqued. It may be worth, if you don't want to get your hands too dirty, back off the 4 bolts a little and then tightening like I described, starting at top left, then bottom right followed by the remaining two. Only tightening each one 90o at a time untill snug, then a final 90o.

Shouldn't need to remove the suspension arm for that.

If that fails, just need a new rubber. Then you nay need to remove the top or bottom boot fixing the suspension. Its only one bolt per arm.

If you did it yourself, you'll laugh at how easy this job is and be glad you saves the money!

A competent mechanic that knows the machine will have a valve cover gasket swapped in less than an hours labour.

Edit: If the issue only started once you changed the oil, you could try removing some oil so its sitting halfway from min to max (about 100cc less if remembering rightly) and see if it still drips. Empty a shampoo bottle, and use the pump to get it out.

Update:

Talked to two mechanics today both are saying it's probably just a little bit of seepage and shouldn't be too much to worry about and that if it's not draining the oil down than to get it looked at when the 9,000 mile maintenance happens and I need a valve adjustment
