boost
help please
this is driving me made
the car did boost at 14psi and hold that as well / now i have had my new plugs in thay are 6bs the car only boost to 10psi i think the ecu has hade a reset and i do have a big leak from the rad it is a 1999uk2000
i have cleaned the idle air and the boost solenoid
wot should be the vacum at idle and when you are slowing down
i get 25 on idle over 30 when slowing
this is with the engine off
i think this is the boost sol and number 2
i am doing my rad on sat can i give the turbo a good flush through this pip
and wot is this
many many thanks

With the engine off the gauge should read zero. On over run or coasting off throttle it should be reading minus, I think -17 ish. The bottom picture is the carbon catch canister which helps control emissions.
If nothing has changed expect the plugs then that is, at a guess, where the problem may lie. Either the plugs are incorrect or have been incorrectly gapped. An NGK plug should be PFR6b. Or maybe a vacuum hose has been knocked loose.

over run is 30- on coasting yes i get 17ish
i have PFR6b wot gap should thay be or should i put in PFR7b
i have look over the pips time and time agane
there is no clip on 1 pip pip2 i just cannot get it all the way on

All hoses should be clipped. The top one looks like the turbo outlet, this should deffo be push on fully and clipped.
A standand car will be fine with PFR6b's, think gapped 0.7mm. 7b's for modified cars.

I've been reading your other posts, all very confusing. Looks like your boost gauge is useless, DV is not working correctly, Cooling radiator at the front of the engine bay, leak or no leak will not affect running short term. Intercooler at the top of the engine should not be leaking at all.

Nothing to do with your spelling.
From reading your other posts too it seems that there may be a few faults with the car. Some of the faults could have a direct impact on boost pressure. The boost pipe will have become hard due to its age, that is probably why it is hard to seat, put some lubricant on the edge of the hose to help it slip on. The boost gauge sounds faulty, replace. In another post you say the Dump Valve may be faulty, replace with a standard item. The turbo impeller should not be cleaned through with water. The Impreza Turbo does not have a Carburettor, it uses an injection system. A colder plug will not higher or lower boost, perhaps checked that they are torqued and gapped correctly. With regards to the radweld you put in, its unlikely to have blocked anything unless you have used loads, perhaps run it through with some flush if you are worried. Who does the work on the car?

Oil shouldn't be overfilled. A little bit over shouldn't do any damage, nevertheless I would drain some, to about 3/4 full. Too much oil may contaminate the boost solenoid.
Like I said earlier, there seems to be lots wrong with your car, and no disrespect but I think you'd be better off taking it to a garage.

but i will fit new rad new boost gauge get a new dv put the that pip on with wd40 and put a clip on the other pip and reset plugs to 0.7 if that dones not work then to the garage we go
ps thanks for all your help
