Need some advice

What is your acceptance criteria for small leaks? 1990 GW runs good accept for "Hot starts" which I have learned to deal with. However I do have a small oil leak from either the pan gasket or RMS. Small being maybe 10-12 drips after driving and sitting all night. Also, one or two drips from AT pan every now and then.
I don't necessarily want to dig into RMS if I don't "have" to as I have read where some folks have to do this several times to get it right and I am sure I will be in that camp.

Lastly, went to 15-40 oil on last change causing a little blow by in the cleaner which I haven't seen before so I think I will go back to 10-30 as my oil pressure seems a bit high at start up. Any thoughts?

Thanks for any input

I consider this a subjective question. For me it is a balance between environmental responsibility, economics, and discipline (remembering to check levels).

As long as I don't slip and fall on my tail getting in, I'm good.

Really though, not bad considering. Just keep an eye on it.

Thanks

I agree on the subjective part. I am kind of anal about checking levels so good there. Darwood only gets driven 1500-2K a year with most being in winter as my JK gets a little sqirrley

I've been able to bird dog and fix all the leaks except the main seal leak. I've got 200k miles on the original engine (still runs great) and just live with a few drops per night. I only have to add one quart of oil between changes (at 3000 mi. intervals). My wife isn't crazy about it but I have a scrap piece of plywood under my spot in the garage to catch the drops. The only pain is whenever I go to a person's home who has a super nice driveway. I feel bad leaving my little mark, so I try to park in the street.

From what I understand, it's a pretty major deal to replace the main seal, although I have one friend who says he can do it without pulling the engine. Someone else here may know if that's doable. I'm just going to deal with the minor leak until the inevitable happens and change the main seal then.

Your friend is correct. It's a 2 piece seal, no need to remove the engine or the transmission.

If you jack it up and put jack stands under the frame behind the springs, the front axle can drop down, and you have enough clearance to drop the pan.

I get drips from the valve covers and RMS sometimes but my oil level has been good and I haven't had to add any since I did the change. I'd say when you get to the point of having to put in a quart every 1-3 weeks you should fix the problem.

Oh yeah one more thing on "leaks" vs "drips". If you had a real leak there would be a puddle under there but if there's an oil spot maybe the size of a modern cell phone then that's just harmless drips. Oil tends to spread on concrete and asphalt and makes the drips look larger than they are.
