I run a bead of silicone on it to seal them.

 

I didn't put anything on mine when I put it back together. Hopefully I don't have a problem. If they make it like that I'm assuming it should be okay.

 

Ill try a small line of gasket maker and do a boost leak test. Seems to fit pretty snug but will do a little gasket maker to feel better about it.

 

Good idea. Some actually come with orings however I don't believe yours does.

 

Most Garrett CHRA's will leak. It's highly recommended to put a small amt. of RTV between the chra and comp. cover.

 

Some have an O-ring, just to be safe i would put some RTV on it to get that extra bit of reassurance.

 

If there is no o-ring I would clean it very well and put a VERY thin layer of RTV if you want. I chose not to because it did not come that way.

 

All actual Garrett T04E covers will use a thin o-ring....the cover is grooved accordingly to accept the o-ring. Garrett T04B covers use a thin paper gasket.

Many Turbonetics and other Garrett wannabes do not use a gasket and suffer from chronic boost leaks at the cover as a result. If you do use RTV, be sure the turbo has been test-fitted to your application and the cover's alignment has been marked because once the RTV dries the cover will be glued in place.

 

jusmx141- I lined up the turbo with a marker. Then removed the turbo. I applied a small amount of rtv and finger tightened the compressor housing as directed by the rtv silicone tube. I then fully tightened down the housing without turning it at all, and it boost leaked at 20psi perfectly! Just now it smokes horribly and is in need of a rebuild so it was pointless, lol.

It's a PTE junker- you'd expect it to work perfectly without any type of random failure for more than 1000 miles? You need to do some reading on the reliability of the garbage they sell.

 

That sucks. Does it have shaft play? Are you feeding the correct oil pressure with the correct drain? Precision turbos are such a crap shoot.

 

Burnett03- Theres a lot of shaft play but i've been reading of a oil restricter. I understand what it does but i dont have it. I have a oil feed line coming from the front of the head, not side banjo, with a filter, going into the turbo. I think i might need a restrictor when i re-install the turbo after the rebuild.
