I've read some threads about the top banjo bolt for the turbo oil feed, which can clog up and cause the turbo to starve of oil. Some people are blaming the tiny mesh filter inside the bolt and I've read that it's advisable to simply drill it out.
Has anyone actually done that and is it a good idea? Doesn't it serve a purpose...?
My QV has done close to 120.000 km. and has been mapped for a few years now, so I would very much like the turbo not to be starved of oil!

Why don't you just replace the banjo bolt which has the filter?
Because I can't find it anywhere. I found one in the UK i believe it was. It costs around 18 GBP + shipping to Denmark, so I'm going to end up spending something like 30 gbp for a single bolt...
So if it was advisable to simply drill out the filter, I thought I might as well just do that. It is after all just a bolt with a hole in it :)

Bump - No one has any experience with that bolt? I found some older threads regarding the matter, but nothing of late.

the filter is there to keep harmful and hard eposits, or debris, to reach the turbo bearings.

If the oil is changed timely, you won't get any clogging of the filter in the bolt. I'd just check and refit if clean.

If you do decide to drill out the filter, make sure no debris is left in the bolt!

my dealer just installed a new banjo bolt on my QV. The bolt is around 18 euro plus a few minutes of installation.
Gives me a good feeling and hope it will reduce chance of insufficient oil to the turbo.

I dont understand the need for having it sent from UK to Denmark; would suggest you just get it delivered by a local danish dealer?

Should I get my Banjo bolt replaced also ? I just bought it a 2011 model with 40,000Km on the clock
yes, absolutely as it can only prevent issues!
There is no reason not to (except a few euro's / dollars)

good practice is also to change 2 copper washers on boths sides of pipe mounting.
on polish AR forum, people either change that banjobolt every say 2-3 oil changs, or replace it with the screw without filter (one like on return from turbo? as far as I heard for 1.4MA engines, it was OK, but never heard about 1.75) or drill filter out (get out all tiny metal bits to avoid risking turbo/engine damage - for me bit too risky). choice is yours.

banjobolt is easily available from any dealer (may need a few days wait if they do not stock it), I paid order of EUR14 for it 1.5 year ago.

what is the Alfa Romeo part number of the banjo bolt with the filter and the bolt that does not come with a filter and can replace the one that has it?

Thank you.

I was talking to my Alfa Dealer service department today and the guy says hes never heard of the Banjo Bolt replacement and never seen anyone doing that in Sydney Australia at least. He also looked up the part and said its not just a cheap part but $100-200 inclusive. He reckons all this discussion on this forum is a waste of time. :sleeping:

2 posts earlier somebody advised part number for banjobolt. rest you can check yourself in eper online.

in terms of using return screw instead of banjobolt filter,i read that such trick works on 1.4 engines,but do not know if works on 1.75.

I can't read out what is the part number of the banjo bolt that does not have a filter inside.
It works. Just need the part number to order. I will post pictures when installed.
Do I need 2 bolts(bolt on the turbine has a filter?) or one?

My Local Alfa Specialist and Alfa Dealer both said theyve never heard of people changing the Banjo Bolt out of all the hundreds of 1750 turbos theyve seen. They reckon all this talk on the website is a waste of time. They said who are you going to listen to some people on a website or professionals that service Alfas everyday ?!

Anyway thats how we roll in Australia anyway.

turbines in tbi die too often and too early when people follow manufacturer recommendations.thats why people on forums work out something preventive, since manufacturer and dealer services do not bother(they are rather happy if after a few years you visit them for costly turbo replace).there is a few reasons of turbo failures according to forum community. one is too long oil change intervals, two is poor selenia star pe recommended in instruction manual(at least in europe,not sure about australua etc),3 with above being case banjobolt filter may restrict oil flow(because will get stuck with deposits).all above do not help turbine for sure. of course it is not all to blame single people had issues wit leaking injector causing oil to be full (a few %) of petrol or one guy had problems with seal around oil pump and so poor lubrication,but such are super rare,so i guess main problem for turbo are the 3 first things i mentioned.
banjobolt filter cost is small, order of eur15,so people do replace it just in case,surely no harm,likely only goid for turbone. btw on 1.4 giuliettas people in poland did pictures where this mesh inside was cracked and small bits were missing (went through turbine to the engine), so i have strong reason to replace it from time to time,as on tbi engines this banjobolt seems very similar and likely could suffer the same.

if you do not mind changing banjobolt filter every a few years,you just use the one with filter 55224860. you do not touch anything else (you may only check if the hose is not clogged with deposits/burnt oil) some people complained for this when they followed manufacturer oil change intervals and reached say 100kkm). dont forget about using 2 new washers 55227760 (not a must but highly recommended)-they cost pennys.

Only problem is I did a cost of those parts from the dealer and they cost over $200-300 or many many times 15 EUR by the time they get to Australia.

Is there another site I can get them cheaper ?
