My 89 festiva is getting small amounts of oil in the air intake breather and on 1 and 3 of the spark plugs. Trying to figure out what this might be. I have recently changed valve cover gasket, spark plugs and pcv valve. It looks to be coming from the crankcase ventilation. What can I do? What might the problems be? Didn't have this problem till I changed the pcv valve, it looks clean.

Oil on spark plugs and intake breather
Is it coming up through the pcv hose or through the hose that lets the air into the valve cover?
The typical cause and solution is excess blow by from poor rings and installing a catch can.
How did the baffles in the valve cover look when you replaced the gasket? Did they need to be cleaned?
Do you still have the old pcv valve?

It's coming from the tube on top of valve cover not the PCV. I cleaned everything thoroughly when I installed gasket. The other PCV broke, thats why I replaced it. I heard seafoam might work. If a rebuild is required, has anyone done one and how much might it cost, a good rebuild is possibly beneficial depending on cost, car has 250k miles on it

Try this, take to cover off and the plate that cover the baffles. Clean everything really good and fill the baffles space with thick wire-mesh( don't know how is it called in English) , like this one: http://www.inbrisa.com/contraste-pre...alambrina.html
Its like a mini-catch can but inside the valve cover. it may reduce the problem a little... but if you want to know exactly what it is, do a compression and a leak tests.

A rebuild can be cheap or expensive depending on part quality and how much you want to do. It takes a lot of time either way. You should do some research on it first to figure out what you would all want to do. Many rebuilds fail because the parts in the kit are out of tolerance. You would need to find all their specs and measure every part when it arrives and be prepared to have to send it back and get another. Buying another used B3 that doesn't leak is cheaper but not guaranteed to last. A good catch can is $100. 2 cheap ones are also $100. Thats the route i chose.
I you do a rebuild consider replacing valve stem seals. Are your hla's ticking? Make sure the kit has the appropriate gaskets as well as the rings and bearings. Some kits i have seen dont come with both crankshaft seals, oil pan seal, trans output shaft seals, cam seals... Also engine assembly lube. Its a good time to replace your clutch if its older...
Some people would add oil additives but after doing what i believe is a lot of research i concluded they are worthless and cause more issues than they solve on an engine you want to last more than a year or 2.Last edited by ryanprins13; 06-13-2016, 03:02 PM.
