How do you overload an oil filter head?

[Gecko]

A PoS casting is my guess.

So I was minding my own business splitting a trees worth of fire wood when the oil filter sails past and I'm hosed down with warm oil.
It's a chinese log-splitter with a spin-on filter on the return line (hanging off the tank), so I can't see how it could run over pressure. My best guess is the casting, but the fracture does look like and overload.

Anyone want to offer some enlightenment?

Bad casting. Looks like sand inclusions.

the white spots are just a bit of oxide caused by the corrosive cleaner and hot water cleaning process I used (I put it in the dishwasher - ).

Resonance ? , heavy filter full of oil causing fatigue, with a bit of bottom of the thread too sharp for good measure thrown in.

Chinese covers it

 

[Gecko]

yeah - I'll just put it down to being chinese.
It was a quick failure and doesn't show the 'beach lines' that are characteristic of fatigue.

I'll try to get a replacement today, but when it goes back in, it'll also get a Pressure/Temp gauge so I can see when the filter needs changing. It might stop me overheating the oil too. I've been using the analogue technique - if the cylinder is too hot to touch, I kill the engine and we both cool down.

Wrong filter, thread to tight, or been knocked!

Good ideas - the filter and head were packaged together, so you'd think they'd be a match.
Unfortunatly, the filter has no numbers or other identification to help decide if it's suitable of not - I just relied on the OEM gear being appropriate. I bought it new and it's only got 40~50 hours on it.

"Taking a knock" could certainly cause a fracture like this. Hadn't thought about it, but it is rather exposed. When you are working, the filter is next to your knee, but you can't see it behind the log tray. If it took a knock, you'd never see it.

A dishwasher (or diffwasher as it's become known) is a wondrous thing when it comes to getting things clean for assembly.
You've given a head a valve grind and want to be confident you've got all the grinding paste out of there - a dishwasher is your friend. The trouble is a domestic dishwasher won't take a 6-cyl head (I know because I've tried!).

Pro tip: Get all the hypoid out of your gearbox or the kitchen will stink for days.

Always remember a plant fitter coming to our yard, doing a load of graft and then washing his hands with spray brake cleaner despite me telling him there’s a wash room lol…

the thinners was just for the paint splashes from the fabby's friend .... a precursor to Wurth's finest hand reiniger

I’ll remember that tip, mind you if I tried any of this the smell in the kitchen would be the least of my problems.

When I worked on the assembly line of a well-known engine manufacturer over twenty years ago, they had a giant dish washer for washing the heads. It weighed seven tonnes. Some bright young engineer decided it was too expensive to run so it got outed in favour of trusting the suppliers to wash the heads. That worked out well. Sometimes the casting sand was falling out of the heads as they were moved to the assembly line.

old dishwashers make great component washers ..... I have one here which Pam is constantly insisting on me chucking out .... I just keep moving it somewhere else out of sight ... 'til she spots it again .... they get up to serious temperatures and happily cope with some pretty potent detergents/cleaners .... used to use one a lot for engine re- building .... can't get a V8 block in one though

Minimum water temp in most dishwashers is 60c, they don't tell you but if you connect hot water to them rather than cold (if you have pressurised hot) it knocks about 20mins off cycle time (and a lot off leccy bill)

ours is both ... cold for initial rinse then a final super hot one, 'fore it all gets cooked dry
