View Full Version : How-Not-To: Change oil with Shrock skids

I try to be clever, but life continues to show me that I'm only half clever...

I like my Shrock skids. I feel MUCH better about sliding over rocks with the Shrock skids as opposed to the OEM skids. However, although Shrockworks provided an oval cutout for the oil pan drain plug it seemed apparent that oil pouring from the pan would arc beyond the oval cutout. So, being the clever guy that I am, I fashioned a funnel that would catch the arc of fluid and direct it through the cutout. Being cautious about this new technique, I put down a drop cloth and gathered rags.

So, I loosen the oil pan bolt, line up the funnel, remove the bolt with my fingers, and sure enough the funnel catches the oil and directs it through the cutout. For about 3 seconds...

The funnel can't handle the flow of oil and over flows. The oil is now flowing around the funnel into the drain pan and also onto the engine skid. Here I am, laying on the garage floor, one hand still holding drain plug bolt, one hand steadying the funnel. No problem. Put the bolt back in the drain plug. Oops, dropped the bolt in the funnel. Now the funnel is blocked and ALL the oil is draining on the skid. (BTW, the engine skid can hold a LOT of oil.) Oil is now draining off the skid in the other cutouts. I stick my finger in the oil pan drain hole, use my other hand to attempt to position the relatively small square oil drain pan to catch oil draining from 3 holes, and try to figure out my next brillant move.

Eventually I'm able to remove the funnel, and allow the oil pan to drain through the Shrock oval cutout by limiting the amount of oil flowing from the pan with my finger.

Many rags later, I have as much of the oil wiped off the skid as I can manage (did I mention that I'm lazy and didn't just drop the skid?), wiped up the pool of oil on the drop cloth (drop cloth good!), fished the bolt out of the funnel in the drain pan, and re-installed the bolt in the oil pan.

Now for the filter... Actually it went MUCH better. Lucky me.

Next time I might just remove the skid. Until then I'm going to leave the drop cloth under the truck to deal with the inevitable drips. :o

How do the gurus change oil on a vehicle with full skids?

If i were you... I would widen that hole.... grinder... sawzall something.

Here is another idea but only since you have skid plates.

Without plates I would not use that.

Good idea. Just extend the oval.

Even better! Thanks!

Yup get one of those quick drains you can put a hose on and the hose can go right through your hole in the skid :)

Last oil change I took some plumbers putty and closed off the area between the oil pan and the skid so that whatever comes out of the oil pan can only go through the skid plate cutout. I'm not sure if it actually took less time to do that or to just take off the skid, and it isn't something that will really stay in place - you need to do it everytime. I haven't decided on my strategy next time around.

Those valves make it much cleaner but make draining take five times longer. If your like me and like 3 minute oil changes you may want a different solution.

That would have helped contain the flood! I think I will get one of the valves, drop the skid plate the next time, clean it off, and install the valve. I'll get a cap to cover the nipple to keep it from filling with dirt/dust between drains.

That commercial came to mind while laying under the truck with oil raining down. :D Actually I think only about 1/2 quart ended up on the drop cloth, but at the time it seemed like MUCH more.

I like the idea of a 3 minute oil change, but it usually takes 30 minutes because I pull the filter while the pan is draining (assuming it is actually draining INTO the catch pan), check other fluids, drink a beer, dream about upgrades...

There is your problem, you should be dreaming about upgrades all hours of the day.:D

I just take newspaper and fold it up into the drain "oval" around the drain plug. It blocks the oil from running down the skids and also makes a drip guide to the drain pan once it slows to a slow drip.

When you can change that oil and leave no drips, Grasshopper, you will be ready to wheel with Jeeps.
I think I'm going to get one of those valves as I have limited access as well.
It may be a PITA now but on the first good rock bash you'll be glad you have 'em.

This is all your fault. You tempted me with the skids! :D

I just use some very strategically placed paper towels but I remember the first time I changed the oil after my shrocks were in place. When I first took the plug out it was draining fine through the hole so I walked away to wait for it to drain when I came back the oil had arched up to the plate and by that time I had oil running out on all sides of the skid plate. The filter is just a pain in the ass I took that drip guide off and made one of my own that was longer and a little wider so the oil doesn't roll back and drip on the sway bar and up onto the frame any more.
