Default Re: Main Seal Leaking, What to do?

I've driven the car every day, and haven't had any issues with the oil light coming on . The weekend that this happened, I drove 360 miles one day, and about 50 over the next two days. Then, I drove 80 miles and the oil light came on. Prior to that, I had some mechanical work done (shocks, struts, a new rack and pinion, and brakes).

I've probably put at least 1,500 miles on the car since April, if not more.

The thing I'm wondering is this: is it logical to think that all that driving I did in one weekend was enough to lower the oil enough to set off the light--but the 1,500+ miles I've put on since wasn't enough to do it again? Or should I be considering the idea that the mechanic messed up somewhere along the lines?

I'm asking because 1) I'm going to a different mechanic this Friday for an oil change, and 2) I'm going to be driving another 300 miles next weekend + whatever driving I do there, and 300 miles back home. So I'm worried about whether I'm going to have any issues again or not. I'm doing the oil change right before, so that I *hopefully* won't be a quart low when I travel.

I guess basically I'm asking if putting 400 miles on in a three day period would cause more oil to leak through the main seal than putting 1,500 miles (mainly city) on in four months would. More or less, so I know whether I need to check the oil every time I start the car on my upcoming trip or not.

Thanks for all of your suggestions. I'm going to be working up to getting these repairs done as soon as possible.

Have a great day.
Patrick.
Hey Patrick. We bought the wife's 06 band new. It now has over 160 thousand on it. She has changed the oil religiously at 3,000 miles since the first day we got it. And the thing has just as religiously burned a quart of oil between every single oil change since the very first one! ;~)

From what I was told by the dealer...and from other Cruiser owners...just about ALL of them do it. HowEVER, at about 100 thousand miles, the oil consumption went up to about a quart every 1,500 to 2,000 miles. So, I had her put a oil additive product in it that I've been using since the 60's. It took a couple applications, but it went back to better than it was when it was new. Less than a quart every 3,000 miles.

My question to you would be, have you SEEN fresh oil on the ground underneath the car when you park it? If you haven't, even if it is leaking slightly...it's not likely enough to hurt the car. Main seals don't usually just fail. They are a wear component that gradually gets worse and worse. Unless there is a bigger problem, like compression getting into block, it is hard to see how the main seals could be blown out bad enough to fail catastrophically.

But I suppose anything is possible. And with my everything Murphy said goes double for me kind of luck...even LIKELY! ;~)

Here's the thing. The PVC valve on your car sticking can cause it to consume oil. Heck, it can even cause it to blow smoke like a crop duster. Normal wear to oil rings can and DO cause oil consumption with age. So loss of oil can be a lot of things that are not necessarily going to lead to a catastrophic failure.

Were it me, I would go buy a GOOD QUALITY oil additive that says conditions seals and add it to the oil in your car today. As per directed on the bottle of course. Then drive it normally until the oil change Friday. Then buy an extra quart of oil and carry it with you and just monitor the oil on your trip and add the oil if it gets low.

But keep in mind...NEVER over fill the oil in you car's engine or transmission. That WILL blow out the seals and lead to engine failure. NO QUESTION!

As a matter of fact, I ALWAYS check the oil after my wife has the oil changed in her's to make sure that they not only got it full...which they do NOT do half the time...but that some jackwagon ain't over filled it. ;~)

I suggest everyone do the same if you pay to have it changed.

Oh, and to answer your question...I doubt it. In town driving is usually harder on your car than highway driving. The constant stopping and starting puts a LOT higher stresses on engine components than a constant speed. The ONLY difference it might make is that MAYbe if you are running it at high RPMs, the seals may allow more oil to push through the crank seal seats.

But unless the seal seat on the crank was flawed from the factory or somehow damaged by metal in the oil...it's hard to see that being the case. Especially since it's got all those miles and just now starting. Oh, or if the harmonic balancer has failed or been damaged and it's setting up weird harmonics at highway speeds. But that's about as rare as hen's teeth! ;~)

So I'd say, put in the oil additive NOW, have the oil changed and check the oil before you leave, carry an extra quart in case and see what happens. UNLESS you are seeing a bunch of oil on the ground everywhere you park that you KNOW is coming from your little cruiser. In THAT case...you have a problem you need to address as soon a possible.

By the way, the additive I use a lot is something called Marvel Mystery Oil. I've used it for years and it works pretty good for oil consumption. It SAYS it's a fuel additive as well, but I've never tried it for that. But just get a good brand that says it conditions seals and try it. It can't hurt and it might help. ;~)
