Super Major engine - advice on oil spill through breather
Posted: Tue Jun 26, 2018 7:02 pm
Thank you for accepting me as a forum member.
At the moment I'm not owning a tractor, but I'm constantly keeping my eyes open for "the proper" Super Major popping up for sale.
However that's not my topic at the moment.
I'm owning a boat that's equipped with a Parsons Pike Marine engine. It was a British company making marine versions of (mostly) various Ford/Fordson engines.
Mine is equivalent to a Super Major and/or (I think) some 4 cyl Trader. According to the papers it's built 1962.
Anyhow it's more of an "industrial" form of the engine rather than the proper tractor version.
Hope this is close enough to keep me in this forum.
After purchase two years ago the engine went through an overhaul and received a complete engine kit with new liners, pistons, seals, o-rings and you name it.
The overhaul was done by a very experienced tractor mechanic. I'd contact him again if he would still be around. Sadly not though.
After the overhaul I've used the boat (running the engine) for about 50 hours in total. Not really much in other words.
For 17 of those hours it had a too large propeller which unabled it to reach proper rpm.
Now it's better but still not perfect, so that'll be adjusted. I currently don't have a tachometer (yet).
Being in a boat, the engine is mostly working rather hard. Like "constantly driving uphill" as they say about boat engines.
I'm not sure if it's hard enough for bedding in, but I hope so.
That was the background. Here's the ongoing problem.
Last week I took it for the first proper tour of the summer along the coast.
After about two hours it started spilling oil. I localised it to the breather on the timing cover.
So after coming home I tried to read into it. Among other places also this forum.
After that I checked the breather and unsurprisingly it's blowing air.
I also read into the rocker cover breather and this one do not have a connection to the air cleaner stack.
There is no open pipe in the air cleaner stack to connect to either.
So it seems like it has been like that since... 1962...?
Don't understand why it would have been changed.
My fear is of course that there is something wrong with the piston rings or some similar problem that requires opening it up again (it's horribly difficult to remove it from the boat and there's almost no space in the boat).
Or might there be some other - more "kind" problems that are easy to solve?
Unfortunately I do at the moment not know what the oil pressure might be. I need to have that checked properly.
