Oil comeing out of air intake when running

Postby lotusesprit1 » Mon May 14, 2018 8:14 pm

Hi,i wonder if anyone can help.I bought a part restored T20 petrol paraffin.When running it has clean fresh engine oil comeing out of the air intake,it is not burning oil,no smoke.My worst fear is that the engine has been put together without scraper rings.It is also popping in the exhaust.Can anyone please advise,thanking you,Fred Farrell.

Welcome Fred :smile:

The ' popping ' is symptomatic of poor rocker cover venting , I suppose this might be building enough pressure to force air out of the intake . I hope it isn't rings as you suspect .
First things first , is the air filter oil bath over filled ? no more than up to the fill level inside the bowl and make sure the small holes that allow oil into the centre reservoir aren't filled in .

The mesh should be clean , not just washed out but removed , unrolled , cleaned and put back , they can look like blocks of wood when really dirty.

If this is all ok then look to the rocker cover vent ,

This valve is the source of popping and fating on most TED engines , it needs to be complete , unblocked and working. It isn't hard to replace any missing bits , the pin is just a bent paper clip , the disc a small coin filed down to fit .

Welcome Fred. When you have a minute, do not forget to tell us a bit about you and your tractor in the Member Introductions section. We also require photos. :wink: :lol:

Here is a link to some popping that I was experiencing. Is this what your's sounds like? There is a Youtube link part way down the page. viewtopic.php?f=25&t=3040&start=40

As you will see in my discussion your problems could be timing related or carby related too.
