But, the quick and easy way would be to get a new one from Studebaker International for $30.00. Part number is 527138. S. I. Catalog says this is for '51 - '64 which is not correct. Should be '51 - '63. The '63 models were the first with PCV systems (for all 50 states - California was '61 - '62) but for the first year used a hose adapter that fit the same opening as the road draft tube. Then 1964 models only had the pipe thread fitting instead.Originally posted by doofus View PostKato order the new one those things are nearly impossible to get clean inside!!! BTDT Doofus

Baffles in the cover and / inclusion of coarse material such like metal pot_scrubbers into that space cause oil vapours to coalesce into droplets which can then fall down into the valley and back into the sump. The more gaseous fraction can exit via the draft tube without taking so much oil with it. Employing a PCV systen might be cleaner looking but without adequate baffling, the Oil will still go on being consumed.

This is right at the transition time from draft tube to PCV. I have 3 -259s and they are all configured differently. One has the double vented valve covers with a draft tube and the two others have PVC systems and they are both different. One has dual breather caps with one receiving air through the carburetor air filter. The PCV system on one engine is bolted into the draft tube hole and the other is welded to the valley cover. They both return to the base of the carburetor to consume any excess vapour. It would however be very easy to mix and match in these years and have a bastardized system. It is very important that your engine is configured as designed. The double vented valve cover system is most likely consistent with a draft tube. Some models have the crankcase breather and oil fill directly into the front of the valley cover, this system may not be consistent with a draft tube. There are probably about 6-8 possible breather combinations for the same engine. Make sure your engine is configured as designed.

Simply try using 10W30 instead of 20W50. The heavier oil may be reducing the drain-down speed and flooding over into the lifter valley, particularly during periods where the engine is not up to full running temperature. I use 10W30 Pennzoil and consume less than a quart in 2500 miles at 46000 miles. However, this is a '64 vintage motor with PCV and not draft tube.

In warmer climates like Calif./Texas/Arizona the 20W-50 is fine, but in Ontario I would use 10W-30, especially in Winter on a New Engine.
However I do not think it will affect your Oil buildup/leakage one bit.
Another thing, all 1963-'64 Full Flow Engines as your Late '62 is, used the "Lower" Crankcase PCV Valve System and I find it helpful to remove Moisture and pollutants from the crankcase, it is especially helpful in High Humidity Northern hemisphere areas such as yours.
Bearing eating Acid is formed in Oil as a result of having no forced Crankcase Ventilation System.Last edited by StudeRich; 10-22-2016, 01:00 PM.StudeRich

So this would have had vented rocker covers and a PCV? Why on earth the previous owner did away with that and put a draft tube on it is a puzzler! The plot thickens!

Late model '62 V8 engines did not have the vented valve covers and did have the draft tube even though they did have the full-flow filters. They did have the vent cap in front of the valley cover where the earlier series had the inverted filter. If someone has removed the forward vent assembly and replaced it with a block-off plate, then that could be the source of your problem.
