My fun winter break project (rear cover/seal) The back cover thread holes got stripped when I was doing the cam and I had a leak that bugged the crap out of me. I figured I'd swap the cover and rear main seal while I'm back there. So I started working on the car by myself. Not too bad other than the transmission stuck on my crotch for a few secs. I think putting everything back on by myself might be a bitch!
They say you can't do it by yourself on jackstands...... I surprised myself.
here is the messy leak.

I have to put the new cover on I had to make sure the one I got with part # 12559287 is the same I took off my car with part #12556105-Rear main cover.

I'm on my winter break from school and keeps me busy since I'm not working. Sad I can't drive my baby though.
What are you working on or is it a secret?

well a helicoil isnt exactly a quick fix...you can actually consider it an upgrade over the factory threads in the casting...
a time sert is similar to a helicoil in the sense that you must remove any remaining damaged threads and retap the hole...helicoil is a coil insert that is threaded into the newly tapped bolt hole...the time sert takes it a step further...it is actually a inserted sleeve with a lip and unfinished threads...after removing the rest of the old damaged thread you use a provided tool to engrave a radiused step down below the deck surface...now you tap the bolt hole and thread the insert down into the hole with the provided tool until the lip rests on the engraved step down.....once the lip is sitting in the step down, you have reached the end of the unfinised thread...keep turning it until the tool finishes the thread and locks the insert in place in two locations...the lip on the step down and finishing the unfinished threads slightly mushrooms the bottom of the insert locking it in place on both the top and bottom...
the time sert is definitely a stronger insert, and i will usually use them in bolt holes that must endure a high torque load....head bolts and tranny usually...i will use a helicoil for everything else...before i knew about time serts i used to even helicoil stripped head bolt holes in honda engines i used to build....torqued to 75 lb ft they alwas held fine...the time sert is just added security for not that much more labor time....time sert is about twice the cost of a helicoil...

I know helicoils are pretty good but I was in there so I said hell with it and I got the new cover for a good price. Well I'm gonna clean up my cover that I took out and probably find out where to get the parts for the time sert to fix it and have it just in case this happens again. Hopefully it doesn't. Thanks for the info.

the only place i know of that deals time sert around here is flanders in pasadena...they are a motorcycle parts manufacturer and have a wide assortment there... i believe there is another place in torrance but youd have to look on their website to be for sure...
if your gonna repair it just to have a spare id just use a helicoil...one time sert kit with all the bits and five inserts is almost 60 bucks retail.

Oh no prob. It didn't mess up the gasket. I had to drop the pan to change to an ls6 oil pump when I was doing the cam. When tightening the back bolts the threads got stripped or they were hanging by a thread beforehand. Then the leaking began.

If you still have that leak make sure to check your oil pan gasket. I have had a few of them split on me and it will look like a rear gasket seal or something. Sometimes when you go to do the oil pump that way, part of the seal wants to stay on the bock and the other on the pan. When you let it down it will tear. The other thing is stuff can get in between the pan and gasket and wont let it seal.
