Leaky oil pipe syndrome...part numbers


 

j have the infamous leaking oil pipe, discovered tonite after motoring to mooring...and seeing black water in the bilge...ugh...knew it would happen. oil pressure alarm didn't go off, and i didn't have time to check further...suspect it's a slow leak...bit enough to make the water black..

does amy know part numbers for the pipes, and related hardware? assume i need banjo bolt and new washer? or could i reuse the banjo bolt and just get new pipe and washer?

thx!


 

Sorry that I don't know the part numbers, but I suspect that the folks at Torresen Marine do ()

Their phone number is 231-759-8596.

I wasn't aware that the oil pipe could be a potential problem...thanks for the heads-up.

I got my replacement oil pipes from Torresen.com. They have some regional sales district restrictions though. The first time I ordered, they were out of stock on the long one. It's a very common failure point due to the water pump dripping on it and rusting it out behind the retainer clip. I left the retainer clip off.
The banjo bolts are reusable. Get new copper washers though, with extras.

Thanks guys - spoke to Torresen, I will post the parts diagram and part numbers in the files section..

Whoa! Those Yanmar oil pipes are spendy...what are they made out of...platinum? Sheesh. And they rust out, to boot!

Thanks - i just received the order.

Are there any installation tips here? It seems fairly straightforward - and i can probably find the torque settings somewhere in the yanmar manual somewhere.


ALSO: folks should note that the lube oil pipes ALREADY have the pipe joint bolts (not the Banjo bolts) already brazed onto the pipe. I ordered the pipe joint bolts and now have to return the bolts....so be forewarned!

Will let you all know how the install goes - most of the time spent will be cleaning the 1Quart+ of diesel fuel that spilled into the bilge under the engine.....sigh

that's how they make a profit!

BTW - see my prior response to Bob regarding parts nomenclature...

Yep, the pipe and banjo fittings are assembled. My parts manual shows them in a drawing so I never thought to order otherwise. When they were out of stock I tried to make the front pipe from 8mm stainless pipe and the fittings I un-sweated from the old one. After all that aggravation, and having a weepy joint anyway, the price of the new ones seemed rather reasonable. The lasting benefit of that project is a leftover piece of 1/4" tubing that fits my dipstick oil pump inlet and reaches to the bottom of the fuel tank. I've pulled some watery fuel out a couple times now in the spring.

As for cleaning the bilge, I tried all sorts of soapy stuff early on, but it was always a mess.
When there was a couple inches of water from the stuffing box and half a quart of oil from the engine all happening at once, I found that letting an absorber sheet or two float in there for a few days would get 99.5% of the oil. Pull the sheets and bag them for disposal. Pump the water into a bucket, mix in some soap to lather up the last few drops. Correct me if I have sinned, but this went over the side with no sheen or residue.
Then a pretty simple soap & water scrub out of the bilge was all it took. I've had a clean sheet under the engine all season now. Just a few dirty drips from checking the oil.

I remember struggling with wrench clearance... Maybe a short adjustable opened way up? (I had a hard time finding a metric one...)
