After getting the spider out for a test drive last night I came back to this morning a small puddle of oil on the floor. Turns out to be a bad OVS. I did some digging and couldn't find anything on how to clean these things. I know they rust after a while but this one seems ok for now. If anyone has posted on how to clean one out it would be much appreciated if you could share it with me.

I would recommend this instead of wasting time trying to clean yours. To get one of these.

I'd love to get one of those but my buget for this car is very small. One of those nice OVS is half of what I bought the car for.

You bought the car for less the 95.00. Thats a good deal.

The OVS is probably the most important misunderstood item on our cars. When it doesn't work it is the root cause of a myriad of mechanical issues going on in the heart of the car.. your car's engine. Ask any knowledgeable mechanic how it is supposed to work and why it is important. This is the shortest most educational video I have found that relates to how your Alfa OVS works.
and ventilates your engine..
and why it can be the source of burnt valves, carbon build up, over heating , fouled plugs, dirty oil in short order, blown seals, ... sounds like a familiar recipe for old Alfa's .. doesn't it?....


. The comment about a 'pool" of oil on the floor gives me a suspicion the crank case has been pressurized and the source of the "pool" of oil is most likely an engine seal that has resigned from it's position of keeping oil inside the motor

you can try soaking it in diesel or solvent and then flushing real good. BUT...I would only attempt that if it's not starting to rust through and you truly believe it to be still functional.

The long term solution is a new OVS...the one that divotandtralee is selling. Cheaper than you will find a NLA OEM one for.

That is very possible. But having the ovs out I can see the bong for the oil return is clogged so I want to take care of that. I will be doing a full motor reseal and headgasket. I have a feeling alot of these issues is due to lack of oil changes causing the oil to sludge and clog the ovs and slowly blow engine seals.

Probably true, how many of us do not see the doctor on a regular basis? or put off basic maintenance around the house. I have been changing the oil in my vehicle every 3k miles for many years, never had a failure in 50 years.
