It seems that the last person to install a re-manufactured HPOP stripped the holes and used helicoil. I did the regular HPOP install (t500 upgrade) after going for a drive everything was fine till the next morning I was leaking oil bad.

Anyways, speed up 3 days later I get the EZ-LOK HPOP Bolt Insert Kit complete kit, instructions are online for it (Riffraff rocks).

I did the drilling without removing the intake manifold (spyder) and used a makita 90 degree drill that I borrowed. The drill bit initially was a tad big for the receiving end of my drill so I slimmed down the drill bit a little bit to fit my drill.

-Definitely will need a 1/2 inch chuck 90 degree drill like the previous reviewer mentioned.
-some sort of vacuum cleaner to aid in the pick up of shavings.
-rags
-and tap sockets

I had the HPOP reservoir previously removed, and I did notice that the passenger side bolt hole penetrated through the casing that holds the gear completely. Out of precautions I put a rag inside as well and while I was drilling I had someone turn the vacuum on to prevent any shavings going into unwanted places.

If you have never used a bolt thread repair kit of some sort make sure you practice somewhere before you even attempt this.

All in all I am very glad this kit exist it definitely saves major headaches.



Works as intended! Great!

I bought this as a last resort after trying to re helicoil a stripped out hole and it worked awesome! Exactly what I needed and saved me thousands on labor by not having to replace the timing cover. Only thing is to make sure you have a 1/2 inch chuck 90 degree drill the bit is big...had to do a little modding to get it to fit in a 3/8
