turbo help please.

[Guest]

hi, i have a BG5A tt wagon and have gone thru 4 primary turbos every time i install 1 they blow a lot of oil into the intercooler. i have no boost the primary turbo get really hot while the secondry one remains cold.

could it be a block in the oil return from the turbo? causing pressure to be bulit ip, and the only place for it to go is thru the turbo seals.

i dont know what 2 do, as the car has been of the road for two years and have put alot of money into it, and now i have had enuff!!!!!!!!!!!

have you got a blocked cat on drivers side??? are the turbos you are installing new or second hand?

[Guest]

have had both cats removed, all second hand turbos as it like 2k for a new one. but the turbos have been going on the cars they came from

[Guest boostcut]

have you checked oil feeds etc?

[Guest]

they seem to be flowing ok

Just FYI, the secondary's are meant to be cooler. Well... that is, they only go when you get over 4000 rpm, so you gotta be boosting pretty hard for them to get up to the same temp.

Given much thought to a single turbo conversion? much less headaches.

Are you always using the same turbo, or have you tried primary turbos from the later models too?

Remove your filter from your feed banjo. Could be blocked as mine was.

[Guest]

banjo feed? nt sure what that is sorry or where it is sorry

[sickmatesick]

banjo feed is the oil feed to the turbo. has a bolt that goes through it with a hole in it

This bolt is located at the cylinder head end of the oil feed pipe

What boost you pushing from the primary turbo?

10-13 is normal depending on model

Do you still have the "cat" downpipe? if not was the boost reset?

What oil are you running?
