Noticed a bit of Oil

Hi All

When I went to take my Tiger out for a quick spin yesterday I noticed a bit more oil on the floor than the odd drop or two I sometimes get. Today I had some time to take a look underneath. I noticed oil on the bottom of the pan and some staining on the side. I felt around the plug and, along the seal, and around the bolts…all felt dry. Upon further examination I noticed a drop of oil hanging from the motor mount and a slimey trail down the right edge of the mount. I have taken a few snaps. I have not been able to lower my Tiger so I can open the hood and take a look and feel around from above. Hope to do that once the weather clears up and I can move out the car below.

Any initial thoughts?

Yes, I know I have the much maligned Tiger Pan, but it was on the car when I got it and seems to be fine. I am close to stock and do not throw my car around as much as some of you with higher performance set ups. The pan came from Cobra Restorers. I checked their web site and they do not carry it any more. It cost $495 in 2000. I am wondering if it is baffled like their cobra pans. That said, this could prove to be an opportunity for a closer look.

And here I thought a new top and paint touch ups were going to be my only winter project.
 
I would check the bolts holding your valve covers on the oil is most likely
coming from a loose gasket. There is a plugged hole on either side of the firewall to get at the back bolts.....have fun.

May just be my monitor but, in the first photo, the 'drip' looks suspiciously green...freeze plug, maybe?

Excellent observation. Now that you mention it, the fluid on the motor mount could be coolant and totally unrelated to the oil on the floor/pan. I had some coolant leakage on the drivers side of the engine a couple of years ago. I was convinced it was a freeze plug until I found that the heater hose was leaking at the the heater valve and dripping down the side of the engine. I did not notice the drip on the under side of the hose and thought for sure it was the freeze plug. It is hard to tell for sure the type fluid on the mount right now since it is kind of greasy and the drip has...well dripped. I will definitely more closely inspect for coolant leaks from the topside, especially around the heater valve. I probably should have learned my lesson last time and put on modern clamps instead of trying to stay original.

Thanks

You guys seen these heat shrink hose clamps before ?. I am going to use them where possible, once I can get them. Supposidly seal better and will look
a lot tidyier as well.

Mal,

Jim's car is quite stock and is entered in many shows, I would bet he has the correct wire and band style clamps ..those are interesting clamps you have found, but not ideal for a standard car

Those are awesome. I hate the look of conventional clamps. Do the really seal as well? I think installation would be troublesome with the tight space in the Tiger engine compartment. Getting an even amount of heat all around the clamp would be about impossible.

Yes...the greenish fluid that was on the motor mount is only on the driver's side.

Michael is correct, I have tried to keep things pretty close to stock. I have all the correct clamps, but I guess I could always change out clamps when I think it might matter. I did that with the fuel filter. I switched to a metal filter after Duke mentioned that my car might just go up in flames with a plastic filter. When it might count I can alwys slip a plastic filter on in a few minutes.
 
I worker at Raychem Corp as an engineer for more that 25 years and am very familar with cross link polymer technology ( Shrink Tubing). We looked at hose
clamps many times but the problem is you can't even come close to the clamping pressures of a mechanical device. They might look good but no OEM's
are using the stuff which should tell you a bunch about the long term advantages. Now if someone would come up with an affordable Nitinol metal ring then you got something..

I like the modern OEM style clamps:

Most people hate them, because they are hard to remove without the special tool. But they look a lot neater than worm drive clamps, and automatically tighten if the hose shrinks for any reason.

Edit: And, they are reusable. I pick them up at the u-pull-it by the handful, for free.

Regards,
John.

I have been doing a bit of research on them. They have been discussed on other car forums. They seem to seal well. No one is complaining. OEM's do use them.

Some dicussion below.

Duke,

The technology is pretty simple. The tube is extruded than iradiated to cross link the polymer and that gives it the ability to expand like a rubber band. After it has been expanded in hot mineral oil it is cooled to hold the larger shape. When you heat it up again the tube tries to go back to it original
extruded shape. As I said before it does not produce great forces and if you go back and look at your dyno run the lower radiator hose just about goes flat
due to the suction. If you remeber that I said the polymer gets elastic at higher temperatures guess what happens......it's not a good application of the technology and besides you have to cut it off to remove it and is not reuseable........Now if you want to put it on your car and just let it sit in your garage and not use it...it can't be beat !!!
