LCR vacum loss

[Lodgey180]

I have a LCR 210
i took rocker cover and throttle body off for painting
when i have put them back on i seem to have a problem with vacum
my boost gauge is running slow and getting bad chatter from my airfilter.

there doesnt seem to be enough vacum to open the DV?

i also took the FPR off to clean the crap that was on the top of it.

I have checked all the vac pipes to dv fpr and inlet manifold and all seem fine

can anyone help or point me in the right direction

anyone??? had to take car off road incase i blow it up..

I think your problem lies in your throttle body refitting.
Did you refit the gasket.
did you refit the vaccum tube connected to the top of the throttle body.
Is the throttle body hose refitted properly.

I would take the throttle body and rocker cover off and refitt them both and be very careful on how you refit them.

 

[Lodgey180]

yes all vacum hoses are connected up properlly.. exactly how it was before..

i never fitted new gaskets mind as the tb one is only like paper anyway and i have no leaks from rocker cover.

I didn't think the gaskets should be reused once the seal is broken.

im gonna order a new throttle body garket and bolts..

the vacum works if you come off the throttle really slow ..

boost gauge works in slow motion lol

anyone else know...

car is still of the road !!

 

[Lodgey180]

bumpy bumpy

also turbo is realllly laggy now..
found 12 faults in ecu but none refer to whats happening

I can't comment on the issue but you should never reuse gaskets...always replace.

 

[Lodgey180]

gaskets have all now been replaced..

really starting to P**s me off

 

[JamJay]

Hmmmm, have you checked the DV or tried putting the OEM one back on and testing again?

List the fault codes you are getting now.

 

[Lodgey180]

yes i have a dv 30 a standard one and now a 007p all no good..

the faults i had was
16804 17526 + 17522 which are all to do with the de-cat
17695 + 17608 which is the n249 bypass
17951 + 17580 + 17987 + 16891 which is when my dopey mate turned the ignition on while the throttle body was off
16486 which i had the maf unplugged
18010 which i presume is when i had the battery disconnected
16497 intake air temp sensor which i put a new connector on last night as it was snapped

 

[LEE69]

Have you re-run vag com after resetting/clearing the codes?

 

[Lodgey180]

no it wasnt my vag com.. i took it to a specialist who just cleared them and gave me a print out.

 

[Lodgey180]

i ahve now replaced the seals on my FPR and the suction pump under the inlet manifold and still no good..

 

[Lodgey180]

problem is now sorted.. it seems that one of my t peices had a restrictor it that has been facing the fpr since i have owned the car.. when i have tidyed up my vac hoses the restrictor faced the DV instead.. cut the restrictor out and all is now fine..

 

[skahigh]

Glad you got it sorted mate, that whole nightmare for one little t-piece must be REALLY irritating!

 

[Lodgey180]

yes considering its been on the car for over a year.. !!!

nevermind.. all is good now lol
