Hi all,

I have a 69 convertible and I have noticed oil under the rear of the car. I don't necessarily see it on the body pan, but the mufflers have oil on them as do the exhaust pipes just rear of the mufflers as they go over the rear axle. I first thought this was a bad pinion seal, but a) the 3rd member is not losing oil, b) the pinion seal appears dry, no weeping and c) this oil looks tan or clear like brake fluid or what you would find in a hydraulic jack. Once in a while I will see some on the ground (a few drops) but not always.

I have yet to crawl into the trunk or remove any interior panels, but could this be fluid from the hydraulic top cylinder or struts? It seems odd that this much would have exited the power top mechanism and the top still work, but it also seems like if there was a leak, it would pool in the trunk or under the seat.

Has anyone experienced this? I assume I will need to crawl in there and look for wet connections. Is a short term fix to check the fluid in the cylinder and then trace it down? I assume once the fluid was completely out, the top would just stop functioning whereever it was a don't want to play russian roulette.

Thanks,
Mike

Could also be brake fluid (are your brakes spongy?)....I'd check your master cylinder and see if you are low on fluid.

Most likely it is coming from your convertible top (either one of the cylinders is leaking or the pump is leaking). On my 65' there is a hole (in the floor) right below each cylinder, so if it leaks, it will drip from these holes. If your pump is leaking, it should be pretty easy to tell by looking in the trunk.

On my 65' there is a brake line junction right where you are describing you are seeing the fluid. It could be that either the rubber hose has a hole or tare or fluid is leaking from the junction connector. I'd really look long and hard for a brake leak as this is a safety issue.

Good luck

Thanks

Thanks

Not brakes, fluid in master ok and this fluid is not affecting painted surfaces. I replaced carpet 2 years ago and noticed air in the line to the driver's side ram (strut) for the top. I was not familiar with convertible components and while I figured something was wrong, the top worked. Coincidentally when I raise the top, the left side labors for the first foot or so of travel.

I have other demons to slay, but when I get time, I will remove the back seat and see what's up.

Thanks again!

Mike

I would strongly suggest you pull the back seat out. Tonight. If that is leaking under the seat from the cylinders, like mine was, it will be quite the mess. But it likely sounds like it is coming from connections at pump. You should be easily be able to access the pump from trunk. It’s right under the cover and if you climb in there you can see if one of those connections is leaking.
