I have a 93 Ford Escort with 94k miles. Over the weekend, we found oil
in one of the spark plug sockets. The guy working on my car said that
my rings are going bad. I've read some other messages and they've
indicated maybe the valve cover gasket needs replaced, which I already
had done a few months ago. The car is running horribly and I'm not
sure if it's worth it to put anymore money into it.
Any info would be appreciated. Thanks.
Both could be right...
Bad Rings (due to previously running low on oil JUST ONCE!) will often
result in high engine crankcase pressure, forcing oil past gaskets.
The easy test is to lay a light piece of paper over the open oil filler
with the engine running at idle. If your PCV system is good and clear,
the paper should stay sucked to the opening. If it bounces off, you
likely have bad rings on at least one cylinder .. OR the PCV valve is
Why did you change the gasket, and what did it run like, and how much oil
did it use per thousand miles, before you did that?
Yeh, I'm a Krusty old Geezer, putting up with my 'smartass' is the price
you pay..DEAL with it!
Since I've owned the car, I've always had an oil leak. The valve cover
gasket was changed about a year ago to fix one of the leaks. I've had
the car to a few different garages to try to find the 2nd leak. 6 weeks
ago, I got new plugs and an oil change. Last week, my car stalled and
when it started back up, it was running like it had a miss. That
cleared up. I took it back to the garage and they said it was really
low on oil (my oil light never came on). the garage said they filled
up the oil and said it was good. When we picked the car back up, it
was still running like it had a miss.
I had someone else take a look at this weekend and they found the oil
in the plug socket. I called the garage back and he said the oil is
because he had the valve cover open when he was working on it.
I'm just confused at this point.

I heard from the mechanic and he said there is blow by around the
rings. He said he's trying to find a nipple type cap that goes over
top of the spark plugs, but he thinks they are no longer sold. Any
ideas where to get this type of thing?
He's talking about a device to keep the oil from fowling that plug.
Such devices are available. You can also try a plug with a hotter heat
range. It sounds like you will need engine work to keep driving it
The bigger lesson here is that you have to open that hood and check the
oil to prevent running low. You need to do this regularly even if the
engine is not using oil to your knowledge. You do not need to be
particularly knowledgeable to check the oil. My nine year old can do it.
