need help with focus st no boost!!! OIL FILTER HOUSING REPLACEMENT
 

thanks for looking, i have had great advice from you lot before, and really need some more please!

my friend has an st on an 07 plate, and had a strange prob, first thing is the car has hardly any boost in low gears, but some more in the higher one's,

now this is the weired bit there is a whining coming from the turbo on tick over, but if you pull up the dip stick a tad it stops????? any clues with this would be great as my mate cant really use the car and cant spare any more cash at fords!!!!

anyone else had a simler prob??

thanks in advance people

The only thing pulling the dip stick out might do is release some back pressure from blow by but i cant see that being an issue, plus if there was any it would blow the dipstick out anyway. On such a new car like an ST its very unlikely plus it would have no relation to the turbo what so ever.
I would pull off the hose to the turbo and check for play in the shaft, if its starved of oil its already shagged. You sure its not just a leak

Oil filter housing diaphragm has gone. Really common fault on the ST's.

oh man your a god!!:lol: now the big question any idea on part numbers?? and price to fix?? i will have a go at fitting it for him if not to much prob....


again many thanks for the quick response thanks god for the fourm's!!!

i think the part is around £150 or you can get it from volvo for a bit cheaper. It's held in with 4 bolts, one on top and 3 from underneath, a wiring plug and a hose connector. Should take about an hour if you're handy with a spanner!

i found a guide somewhere shows you how to do it actually, i'll have a look tomorrow see if i can find it again!

07 focus st not boosting
 

When you put the foot down it only reads 1/4 on the boost gauge any one have any clues what could make this happen ?

I have exactly the same problem with my Mondeo 2.5T.

Thanks for this post!

boost solinoid for your quarter boost. Another common problem!

Hi guys new to this, Iv got the same problem just want to know if your been fix and is working fine now????

I take it you have to drain the oil to do this? As im picking my new Oil Housing up 2moro and am going to try and fit it on the drive... thanks

Boost problem
 

Hello,

I have Focus ST '06 with modification and I have boost problems. I dont have problem that I have always 1/4 of boost, but I dont have proper full boost as I shound have.
Also time to time its like.. its going to boost and then pressure wave around 1/4 of boost (you feel like car is not pushing constantly) and then continue into 3/4. With my Dreamscience ECU map I always had 4/4 of boost.
Boost seems to me also very slow... Turbo lag takes longer than before.

I once had problem with oil housing so I replaced it for new with breath pipe too.
Now I hear just a very little whistle from oil housing... not like when I had problem. Is there possibility that its faulted just a very little?

Or it can be problem with Boost solenoid? Is problem with solenoid shown on diagnostic as fault?

Thanks for help
