Soooo I just snapped the tapper in the vanos cover hole. %*&%#@$!! Time to walk away for a bit.
I'm thinking of getting a reverse threaded drill bit and see if it will back itself out. Does anyone know how much extra material is surrounding those holes? Oh god.... I actually might just take that cover off and see what I can do then.
On a slightly positive note there was oil on the bolt when I took it out leading me to believe that the oil leak is coming from that gasket

This cold weather is a dickhoal.
I was installing a head stud yesterday, almost torqued down, then SNAP
(unfathomable rage and fear, imminent death, and all the foul things of the world all concentrated into a tiny particle and then vomited upon the expanse of my ambiance ).
Some oil in the bottom of the hole prevented the stud from going down further and the cold caused the stud to pull out 2-3 threads from the cold brittle cast iron block. I was able to clean out the hole and thread it back in with plenty of engagement left so all is well in the world, but still. I nearly cried.
My oil filter housing already fell victim to the cold last week. That was bad enough.
Good luck with that tap.

This cold sure does a number to ya mentally, physically and spiritually.
Tried to drill a tiny hole in the tap to fit a reverse thread extractor but the bit just dulled up right away so I stopped. Back on break time. I might just have to drill and tap to a bigger size.

I am sure you will figure out a great solution, but damn does that sound like a heart sinker situation. I hate those. Hoping for the best for both of ya!

This type of stuff really tests me. I have some credit at Kummrow from them putting the head and cams in and I might have Pat do the tapping for me. I have a call into him just waiting for a response.
I also got the heater hoses off of the firewall and now I just need to pop them on the right way. Tomorrow I will head out to Pegasus to get a thicker vacuum hose setup for the BOV.

Pat Kummrow let me borrow his broken tap extractor kit! It got the tap out but it broke up. Once it was cleaned out I noticed that the hole goes straight into the timing cover and I think some metal pieces fell in there. Oh GOD! Next I need to pull the valve cover and see if I can vacuum any bigger pieces out then dump a least 10 quarts of oil down the timing chain with the drain open to rinse any other debris out. Run it for 10-20 minutes then change the oil/filter again.
I might have to helicoil (spelling?) the hole.
I think this is where the oil leak was coming from so this will all be worth it in the end.
Oh GOD!!

Had to helicoil a clutch cover bolt on a ktm one time. It turned out iffy-ish

I've never done one. I have a inner valve cover bolt that I will have to do as well.
I just need to have a little pressure on tightening it. I think the oil was leaking through the threads so I will liquid Teflon seal the bolt up on install.
This better work.

I would use a thread insert rather than a helicoil. It should be easier to get it to seal and should stay put better. Use a tapered tap and don't go all of the way through so that the insert gets snug (think tapered pipe thread) and clean out good with brake cleaner so the loctite sticks good, if the insert is too long then cut/grind the end off once its in there securely.

The doctor will be in the lab this morning if any of you guys near Whitefish Bay want to stop by and see this:
PM me for my address info.

Glad you managed to get that out! Probably going to be some butt clenching on that first start up anyways lol
It's going to be so tight butthole when I turn that key.
I have 2 gallons of oil that I'm going to dump through the motor before startup.
I got a long bolt into the hole that was the issue and it tightened up to where I'm comfortable. Again, thank goodness!!!

Vanos cover has been rtv seal and is now all bolted up. The stripped hole torqued down very nicely. Fhew!!!
Dumped a lot of oil all over the timing chains then looked underneath to see this!!
Which lead to this. How did BP clean all that up again?
I picked up a bigger BOV vacuum line then broke the connector making the line. Stay Hot, doc!!
Also took out my rear trunk lock to try to clean it up and get it to turn again. I got this far.

That doesn't look like cat poop, kinda looks like oil though, is there and oil leek?

Kitty litter, oil dry. Works pretty much the same.

Nicely done on that bolt scavenge. I am pretty damn sure I dropped a nut down the timing chain when putting my head back on, but still cant find anything. I have since fired her up and drove her around the block and nothing bad happened. Lol.
