Oil Fumes

[Ian Crombie UK]

Who better is there to ask??

I am in the process of sending the fumes from the Oil Breather tube(cap removed)to the Oil Bath through a hose pipe, so the fumes will be sucked back into the engine and not via the firewall where it's been choking us on long journeys....as i've been told, it would do no harm and also help lubricate the pistons etc...on the P15 Coupe.....Has anybody done this or am i wrong in doing this??

Try this link and clivk on PVC information this is how it was done when these cars were new

I did that on my 64 Ford Fairlane. It had the big 6 and was suffeing from some blow by, I just took a piece of heater ducting and tied it to the aircleaner snorkle and wired the other end to the oil filler tube on the valve cover. Didn't seem to hurt anything.

Keep in mind that fumes from the filler breather are a symptom of worn piston rings. So you know what the permanent fix is. Also make sure your road draft tube is clean and free of obstructions. There is a mesh deal in there that needs to be serviced once and again. The draft tube is that piec on the manifold side of the engine, just under the exhaust manifold near the firewall. Two bolts one clapm and one throug the fixture at the top. Remove it and give it a good cleaning. Also the bottom is supposed to be cut at and angle so the end opening faces rearward. this causes a low pressure area at the bottom of the pipe to draw the fumes out fo the crankcase.

I had a overhead valve Rambler one time that mesh in the tube was so dirty it blocked the vent. It would always blow the valve cover gasket out. Took a while to figure that one out.

Should the pcv valve go on the oil filler tube or on the road draft tube

at rear on passenger side of the engine?

Here's a link to a previous thread about this topic.

I have exactly the same problem with oil fumes as Ian.

Do both parts of the conversion as listed in the link need to be done, i.e. the oil filler/breather cap pipe connection to the air cleaner as well as the pcv valve link to the inlet manifold from where the downdraft tube is?

Can I just carry out the oil filler to air cleaner part to re route the fumes from the top part of the motor, or is it a complete closed system??

You need an inlet and an outlet for air. Usually the filler acts as the inlet and the tube is the outlet. either way both need to be a clear pathway. If you are just capturing the blow by fumes with a tube and not actually drawing a vacuum through the filler you should be good to go. If you hook it up directly, the draft tube will become the inlet and must flow freely. However this type of set up may draw dust up into the crankcase. That is why the PCV system puts a vacuum on the draft tube. the vacuum created in the crankcase draws air in the filler as it was designed.

Just thought of a great solution to my problem........Let Deano gain the experience on doing his first, then i'll take a little drive to his hometown for a cuppa and maybe he'll say.... it's a doddle,here let me do it for ya... ..lol

Sorry, didn't mean to railroad your thread, although I was rather hoping the same!! I thought I'd catch up with you at The Riot, and be able to take a good look round at what you'd already done......................then copy it!!

[Ian Crombie UK]

Haha....You mentioned Riot..would be indeed...sorry.... don't drive when drinkin'....one or the other.......i could always bring a picture....but rather you did yours first!!!....Give robin a bell..he's good at guessing things..

Ian, I had the same problem with my 46 Dodge. I built a pcv system for it, problem solved. I can send you the instructions and pictures of the system I made if you let me know what your EMail address is. Good luck, Dwayne
