'67 Starting To Burn Oil...Any Way To Decrease?

Hi,

I have a '67 and as far as I know the engine has about 60,000 actual miles on it and has never been out of the car. It's starting to now burn some oil and I'd like to hold off rebuilding the engine since it's all original. Is there any additive that can be used to decrease the amount of burning? What about adding thicker motor oil? I do realize that because of the age of the seals, it will have to be rebuilt eventually. Thanks for the suggestions and merry christmas.

If the oil consumption is from worn valve guides you can do umbrella seals from the top without disassembling the engine. It doesn't correct the mechanical problem but it will keep the oil from running down the valve stem and into the guides.

If it is from the bottom end coming up past the rings there is nothing to do but add oil until you are ready to rebuild it.

Don't go for the J.C. Whitney pills that rebuild your engine as you drive that you only have to remove your spark plugs to install. They won't do it.

By the way. Rebuilding your engine doesn't make the car any less original.

The umbrella valve seals will usually work for awhile. If it's the rings, there are any number of brands of motor honey on the shelf that will also slow down oil burning temporarily.

Valve guides are the likely culprit - I had this problem on a SS 454 Chevrolet Pick-up. Along with oil consumption, one of the plugs was fouling out (#8 cylinder).

Good luck.

I don't think there is any snake oil to fix a mechanical problem. But, I have known MANY old cars that burned oil and ran for many, many years without a problem. Just check the oil level before driving and KEEP OIL IN IT. The ones that burned oil and eventually quit was because of someone driving it without oil in it

Have a competent shop perform a leak down test (this is not the same as a cranking cylinder pressure test) on the cylinders. It will tell the whole story.

Sorry as posted above there is no magic snake oil to correct this problem. It's either rings or valve seals.... Compression and Leakdown will tell the story... If you have an Air compressor you can get a leakdown setup for 80 dollars from Summit or JEGS... Dave...
