Hi All,
I put on an HPX on my 01 7.3l and now have an oil leak. It looks like it is coming from the bolts that hold the intake plenum on mostly on the passenger side. Are there gaskets or seals that need to be replaced to eliminate the oil leak?

At the same time I deleted my ebp, rebuilt the turbo, deleted the AIH, and added the overboost regulator.

Thanks!

 

Moved to the 7.3L forum.

 

Where did you get the HPx from? I had a problem with the hose kit from CNC where oil would spray/leak out of the compression fittings, but it sealed very well on the oil rail where the o-rings were at. It looks like you have a solid tube variety of the HPx.

 

I got the HPX from Riff Raff. I also put in the plenum inserts and new clamps. I wonder if it is blow by from the plenum boots? I cleaned it all up today and put some hair spray inside the boots. I'll see if that fixes the leak.

 

If it is coming from the HPx, you should be able to feel under the fittings and around the oil port for moisture/oil. This is how I found out the CNC HPx was leaking because I could not believe it at first. There was a thin film of oil on the underside of the compression fittings on both sides. Do some digging and let us know what you find.

 

I'm not 100% sure it is coming from the HPx. It may have been leaking from the passenger side plenum boot. It is definetly from the passenger side though. I first noticed a small oil drop about 6 weeks after doing all the work (rebuilt stock turbo, ebpv delete, WW2, turbosmart wastegate, HPx, FRx, plenum inserts w/ new clamps).

The connector at the IPR is also oily, but the whole front of the valley is bone dry.
