Block to Turbo Oil Filter (Inline)
Turbo Mini Forums

I was wondering if anyone has an inline oil filter from the block takeoff to the turbo, as my last turbo was purely raped by something in the oil and it lasted 300miles before being part ex for a new one, and i dont want any shite to get into the new one and i know the mini is a bitch for keeping the oil clean as it shares the gearbox oil and if you crunch a gear wont the little bits run through the turbo? Anyway i was wondering if something like this would be ok to use?

If the oil was so shitty to fuck the turbo in 300 miles, the crank bearings won't be far off either.

No harm fitting an inline filter, but what about your crank bearings? Your second suggestion is completelly inappropriate.

yeah the rest of the engine was goosed

since the engine fucked up i had rebuilt it. And now im rebuilding again but with different pistons as my others broke as you might have seen in another thread i posted of them recently.

And im going to buy one of these and see how it goes :) Cheers

I used to use a bailey filter in my turbo feed. To be honest it never caught any crap. It was always clean even on a fresh build. I change my oil and filter alot though.

well ive had nothing but bad luck with shit in the oil so i dont want to take the chance over something that costs £40 which could save hundreds on a new turbo. do you still have it?

How are you going to protect the engine?

well the oil filter SHOULD be doing its job but it would seem that in the past its not...

here is a photo of the turbo bearing after only 300miles of use with a completely fresh engine build, if the oil filter was doing its job i dont see how this happened this also happened to EVERY other component...

i had the engine cleaned lots of times to make sure all swarf came out, i changed the oil (and filter) after 10min of initial running of the engine and after 100miles! but still this happened. i had a magnetic trap at the back of the gearbox and the normal sump plug..

When you ay you had the block cleaned lots times, how was this done?

I generally spend an hour cleaning the oil galleries with bottle brushes, pipe cleaners, parafin and an air gun. I then spend another hour on the rest of the block, getting a good scrub with a stiff nylon brush and parafin. The oil galleries are then given a final clean with the brush, parafin and compressed air before the gallery plugs are fitted, and the assembly begins imediately. any open holes in the oil supply system yet to be filled with something are taped over.

Simply chucking the block into a hot dip cleaner won't clean the oil galleries.

I say that, and it could well be your oil filter head bypas valve is jammed open.

well, whatever minisport do to clean block is what it had done... they usually dip it, i would have thought they would have used an airline on it. but thanks i will definately give it a clean myself aswell to make sure nothing is in there...

How common is it for the bypass valve to be jammed open? is that the ball bearing in the oil header?

I get the feeling that the real problem is contamination from machining deposits. Were the gallery plugs removed? A dip and a blast with an airline is not suficient. Machining debris is surprisingly abrasive.

I don't think you need an inline filter just for the turbo when the majority only rely on the main oil filter and have no problems. Plus the inline filter for the turbo won't protect the engine. Fix the real problem first :)

Im not being funny, just trying to help you:)

I picked up my new turbo last week, and the guy who built it (crturbos) reckoned the in-line filters were well worth it, especially on a mini (with the engine & box sharing the oil).

I'm hoping it's overkill, but for the sake of £20, I'll be fitting one.

FWIW , I agree that it's unlikely that 'normal' enigne run in debris can have caused the probelms pictured above!

Too many projects!

as long as the filter doesn't restrict the flow of oil to the turbo...

Have you bunged up the release valve in the oil filter housing?

do you run an oil cooler? is could be full of shite.

nope the valve wasnt bunged up, and i did run a cooler but it was brand new and came with the caps on it, so no shite should have been in there.

Oil filters we use on Mini are the same as on any other modern engine, which have much tighter clearances and tolerance. And still such accidents are very rare. So something is wrong in your setup, probably the filter bypass. Think of all these turbo-diesels all over.
