ALH oil filter cap broken

Recommended Posts

The filter seized onto the stem, and I broke it trying to get it off. Anyone have an ALH laying about I can borrow the oil filter cap?

It's also another one of the ALH's common problems, actually all filter lids need replacing eventually.

It was the filter cartridge, it swelled up and seized onto the stem like I'd never seen. If I had taken the time to cut the oily mess off there with a knife, I'd be in business. But oh no, I'll just pull on it a little bit more SNAP!

Even after it broke off, I never did get the stem out.

Hmmmmm.... not finding a lot of info. I can see that if it were to be done I think I would be inclined to do the cap in 2 parts. The cap itself and then the spindle in the middle as a spate part then Loctite them together... I have my hands full at the moment but I am going to circle back to this at some point.....

It looked like some metric acme thread IIRC

Yeah, that is what I recall as well. I am sure it would require a custom ground tool and some trial and error to figure out the thread pitch.

Shouldn't be too hard to match. I think the one on my Jetta is a V-thread profile. Measure the OD, measure the pitch diameter with some thread wires and line the calipers up over a few threads and see what the pitch matches.
