After chasing a couple of boost leak problems I found that the injector seals are leaking at ~24psi. I did have the intake mani off this winter and did lightly coat them in oil after replacing the injectors, after which i did a boost leak test and had no issues.

My question: I am concerned replacing a faulty OEM part with a replacement OEM part that doesn't appear to have been improved. Does anyone know of a replacement seal that works better? I will be installing some PTE1000s in the next couple of weeks so this is a perfect excuse to replace them.

Thanks,
Mike

 

Get the seal kit from FIC - has viton lower seals, they work great....

PTE and FIC have the same bodied injectors - I had PTE's a long time ago and they came with (1) upper o-ring and 1 lower seal (oem type). I ended up getting a fuel leak from the top o-ring......SO I purchased a seal kit from FIC that included the viton lower seal, (2) upper o-rings, and a new hat (none of which PTE included).

I had no more leak issues and the injectors sat in the fuel rail much better....



After speaking with Jens from FIC - he recommended removing the pintle cap which is what he does on his delphi type injectors (same as PTE) Here are "PTE" injectors that I setup to fit in the rail like a "FIC" - they are 850/880's both the same injector just a different look from how one company sets them up from another.

Just a little FYI for you but def. get the viton lower seals if anything.

 

i still wonder why PTE has those damn caps. That cap cost me alot of headache last week.
Ugghhh.
Good call on the seals though! I didnt even know those were an option .

 

thanks for the info travman, i will contact FIC today hopefully.

 

so does removing the cap make them flow more? good call on the seals.

 

I had some original FIC lower seals go bad on me. I called them up and got their Viton seals.
They are fantastic. Very tight fit, nothing is going to leak from there, and should out last the car.

 

shouldnt . I think those tips are just for tighter seal

 

Bump on an old thread....I installed some PTE1200s and they did not seem to fit right / tight. I will do a pressure test later today, but I am sure they are leaking at the lower (manifold side). Should the injectors be so tight that you cannot twist them after being installed ?

 

bump...bringing this thread back to life! i am debating on buying some viton seals. i put PTE injectors in a long time ago and was never comfortable with how loose the bottom orings fit. i wonder if these can be causing the idle issues i seam to have
