My '88 Escort (518,500 miles) has been using more oil than usual lately. I know it has some sludge problems and think maybe the rings are coked. Anyone have any suggestions of what might be used to clean this up without engine dis assembly. The car can still be driven like this and the car isn’t …

I agree the cylinder walls and the rings both probably have significant wear contributing partially to the oil consumption, but since it seems to have increased noticeably over just the last few thousand miles and the engine has had some previous sludge problems I thought maybe the rings were also c…

There are various products on the shelves. I’m reluctant to suggest a brand name, since I don’t use them. They’ll tell you on the bottle that they’re for decoking engine insides.

I’ve used Seafoam many times to decarbonize coked up piston rings with success. Get the engine up to operating temperature and shut the engine off. Remove the vacuum hose from the brake booster. Adapt a hose that’ll fit in the brake booster vacuum hose and into the can of Seafoam. Take a pair of pl…

If the rings are worn, stuck due to past overheating, or the engine has glazed and/or egged cylinder walls then no additive will help. The compression at approx 150 is on the way down but that’s to be expected. It’s amazing the compression is that high considering the total miles on the engine.

I don’t think sucking it (sea-foam) into a running engine will do ANYTHING except blow 98% of it out the exhaust and make a lot of smoke… Rotate the engine to TDC, then 90 degrees more, to position all the pistons at mid-point in their bores…Remove the plugs and introduce 3 or 4 ounces of Sea-Foam …

I like Seafoam but use it at night or call the fire department first. It’ll smoke like crazy and all the neighbors will think your garage is on fire.

What does more oil than usual mean? Eg 1qt/1000 miles or 1qt/500 miles etc. Some of those products can be $$$$ and will you buy a few cases of really inexpensive motor oil which is all this car needs.

Raj asked an excellent question: how MUCH oil is it using? We’re all answering based on the assumption that the usage is dramatic. Is it?

The rate of consumption is about 1quart/800-1000 miles. I’m not going to spend a fortune on the car but thought trying an $8 can of Sea Foam would be worth trying. I’ve even got a partial can in the garage now where I used part of in my motorcycle last summer.

Keep the ideas coming. Right now I’m not driving the car much, waiting on warmer weather so I can get outside and work with it trying to give the engine a good internal cleaning, pull and clean the oil pan and do an oil/filter change. At the mileage I’ve got out of this engine and the condition of the rest of the car it’s no great loss or disappointment if nothing helps, I’ll just continue to drive it as is until the end.
