burning oil 1991 Accord EX

I seem to lose about a quart every 500 miles in my Accord. I switched
to 15w/40 but it does not seem to help.

No oil on the garage floor - and no oil coming from the tailpipe. Any
thoughts?

 

at this rate, it could be a leak somewhere near valve cover area. An oil
seal must be leaking into the cylinders, thus your engine is slowly burning
oil - but not leaking oil per se (thus you cannot find any oil on garage
floor). It could also be a worn out gasket.
When you run the engine, do you see a slightly blue-ish exhaust (not a clear
one)? This kind of problem is not costly to repair in terms of parts (oil
seals are not expensive at all, valve gasket could cost you a fair amount),
however it's a pain in the ass to get to - and defintely not a good idea to
do it yourself unless you have experience.

However don't take it to a dealer/garage yet - I could be totally off. Wait
for some of the more knowledgeable ppl in the forum to reply.

Cheers,

Yuri

Replace the PCV per the Owner's manual. It can suck a LOT of oil out of
your engine if it sticks open, and that can damage your catalytic
converter.

Which engine is that specifically?

You are almost certainly burning it. Someone mentioned PCV valve -
definitely worth a try. But based on the age of the car I am thinking
that the engine is ready for an overhaul. Can you tell us current
miles and how it was maintained and driven?

Engines burning oil don't always smoke like they used to. The
catalytic convertor removes a lot of it - at least until it is
wrecked. Here is an easy test. Warm the car up then have a friend
follow you. After you get it up to about 40 (in fourth gear if it is
a manual), take your foot off the gas and let it coast down to about
30. Then floor it back up to 40. If your friend sees a cloud of blue
smoke when you punch it, the rings are worn.

I've replaced the PCV. I'll report back if it 'does the trick'.

thanks all!!

that would help u tell if its burning it lol thats for sure. to help as a
temporary fix try using Lukas Oil Stabilizer it works depending on how much
u use. go by what is reccomended on the bottle if you use it according to
the bottle you shouldnt have any problems. add more at every oil change.
