If anyone has put a bypass oil filter on a Mk3 Jetta, what filter did you use and where did you mount it?
the stock oil filter is the large size oil filters. they are all the same capacity size, meaning that they have larger pleet area. the Mobile one and Mann and Porilator are the top 3 (among a few others as well) that have the largest pleet count. 30K is the limit on most of these but i never trust that, i would never go past 20K on any filters.garciaplano, what is the "stock large-capacity filter" you mention? Is it a Mann or some other model?
What engine are you putting in the 944? AHU, ALH, or something else?
Exactly what I do, avoids all the nasty overflow while you're trying to get it unscrewed.Idunno. Poking a hole is pretty simple and I don't have a piece of aluminum to hold in place.
Different strokes.
I always drain the pan first, and I've never had it siphon off the filter, always makes a mess, and I let the pan drain completely before going after the filter.If you crack the drain plug loose, and let it drain for a while, the filter will siphon itself down enough that you won't make any mess at all. That is what I always did on my own AHU Jetta (running the larger Mann filter). Which is why I never changed the oil on that particular car at the shop, because I couldn't leave it sit on a lift long enough... but at home in the driveway... I let it sit overnight.
Oddly enough, my AWM Passat, which uses the same filter, and is in the same basic orientation, will absolutely NOT ever siphon down low enough to not drip at least some. And it is FAR worse for making a mess, as on the B5s, the filter area is right above the subframe, which is full of holes, so oil leaks down and runs a couple FEET away and dribbles there, too. So on that, I do the bag method, with a rag, and it minimizes any mess.
Here's what i used on my B4, I don't know if you have the same amount of room on the Jetta:If anyone has put a bypass oil filter on a Mk3 Jetta, what filter did you use and where did you mount it?
I have this configuration with the AMSOIL dual bypass oil filter that I have had for decades... I tend to pop it off and put it on each car when I buy and sell them, transferring it from one to another. Had to replace the hoses once 10ish years ago. I love this system, oil analysis always surprised me with how effective it was.Here's what i used on my B4, I don't know if you have the same amount of room on the Jetta:
Here's the link to were this came up years ago:
Anyone Using Centrifuge or By-pass Oil Filtration
Just wondering if any B4 owners are using or thought about using an oil bypass or oil centrifuge system instead of changing oil every 3-4,00 miles. If you are using either system how is it working and do you see any benefits from it?forums.tdiclub.com
