Blowing oil what to do?

Oct 13, 2003 15 Replies

My Ghia with only 18k on the new engine is blowing oil from the pulley. I've heard this is caused by extra crankcase pressure and that one solution is installing an extra breather in the valve covers. I have two questions: Do you have to install the breather in both valve cover? Does anyone sell a kit? What could be causing this excess pressure? And, ok, fourth question, does indicate a major problem shortly down the road. In other words, am I facing a major rebvuild in the immediate future.

..........................Do a compression test.

who did the rebuild? what size engine? did you break in the rings corrrectly?

a stock rebuild should not develop that kind of pressure.

BAP.

1600 dual port, running stock carb and diz. Well, I thought so. The car has run at high speed which I would have thought would have seated the rings correctly. Is there anything I could do at this point to seat them correctly if they are not?

Here's an example of one:

is it a new aftermarket pulley? I have had a couple that were crap and were just a tad too small. They ended up throwing oil all around the engine.

You didn't overfill the oil, did you? If the pulley is spewing, then you might 'cure' it with a sand seal and a properly sized pulley.

....................After you've done that compression test, you'll know whether it's just one cylinder or all of them. I'd guess that if it's only one that maybe there's a broken ring or even a cracked piston due probably to a manufacturing defect (it can happen).

..................If it is a failure to seat the rings during break-in, there's probably not much that can be done after 18k miles. If you have any long uphill stretches of road, try using full throttle in high gear at lets say 40 mph(?) for a prolonged period. What you're trying to do is maximize the wearing-in process for a brief period. This is just an idea that I remember from years ago and there's a good chance that it won't do much for you now. Good luck.

if you take off the oil cap, what happens? and if you rev up the engine, what happens? If you have a lot of smoke or pressure either do a compression check (good) or a leakdown test (better) to determine what the problem is. I would check cylinders #3 and #4 first.

I just handled a Fuel Injected Super Beetle Conv. and someone had plugged the crankcase vent in the "rebuilt" engine. Owner had used over 12 quarts of oil to get from St. Louis (around 300 miles) to me in Chicago and could not go past 50 mph. Corrected different problems, tuned engine, etc.! When he left I think he used 1-2 quarts to get back home to Alaska (around

4000 miles) driving around 85 mph.

Check your crankcase ventilation! later, dave

Make sure the oil pressure relief valve is not stuck. Happened to me too.

Take fifteen minutes and do a compression check. 20, 30, even 40 hours of speculation won't tell you what fifteen minutes of compression checking will!

Good advice. Make sure your OE system is working properly before you start worrying about add-ons. One of the most common problems is the complete lack of a functioning breather due to parts being left off, exchanged for parts from a different year, or ports just plugged.
