Strange.  Is this on just one of the cams?  Did you remove the studs from the head ever?  I'm just speculating, could the studs not be fully seated and the stud is turning in the aluminum rather than the nut turning on the stud?  Just grasping at straws.  I guess I would just put inserts in all of them at this point.

At this point I am planning on having to repair every last one of them. If in some horrible nightmare I manage to start pulling-out the threads on the repaired holes, that's the point at which I will part it out, ban myself, lease a new Prius, and disappear from the car community forever.

Thanks. I just spit water all over laughing.

Could it maybe justtttt MAYBE be that your torque wrench is out of calibration? I know you said that it is certified and calibrated, but it can EASILY get out of calibration if you leave it out and your offspring decides to play light saber wars with it or you simply tightened it to 100ftlbs and leave it like that over night for example.

Stripped 6 or so with a small beam type torque wrench, went out and bought this Husky click style specifically so that the torque value I need lands right in the middle of the range and includes a calibration certificate.

The other 4 or 5 have been stripped with the new wrench

Out of curiosity, do you have the correct torque value? I have heard that sometimes the bentley/hanes/etc can be off at times

[jc43089]

If the torque value keeps stripping them then don't go so tight?  Insanity is doing the same thing over again expecting different results

He's right.  I checked it against BMW's repair procedures.

Attempt number 6382:

Started torquing intake cam.

Stripped a thread.

(Serenity now!)

Didn't rage.

Repaired stripped thread.

Started torquing cam again and....

1 cam successfully torqued!!!!

I have a few threads to repair on that one still but I hope to get some more time on it tomorrow

Just learned about the Siemens MS41 Tuning in a E28 swap thread, what is your plan for engine management this time?

[B C]

OBD1 413 red label with a Sssquid Tuning chip for now.

I MIGHT try a Miller WAR chip but now that there is a plug and play E36 megasquirt ECU I could certainly see myself getting one of those and some euro S50 throttles

You will have to excuse me, but if and when you start this thing the first time and the cams get scored and seize, I will weep and laugh at the same time. Glad to see you are moving forward without a full on rage.

New woodruff keys installed on the crankshaft.

Originally I went to grab some keys from ECS Tuning but its $65 for a bayg ('sconsin accent in full effect) of 50 keys. Nah. I got a few from McBastard and when they arrived I gave it ye olde redneck Brinell hardness test with a file and sure enough, unhardened, very soft actually. Soft keys will quickly make for sloppy keyways which cause higher impact loads on the keys than normal which causes them to shear and jump timing and lose oil pressure and the end the end the end.

Dont use un-hardened keys for a critical (timing/high torque) application!

Front timing cover installed with BMW gaskets and black RTV. Hardware torqued to 10 nootonmeaters. Front main seal installed.

Why not order a key from the dealer? Ryan usually lets you order onsies on items that they make you buy in bulk

I failed to mention Pelican sells them individually so I ended up getting them there.

Not everyone buys their whole car part by part at the dealership @Earl

I win!

Both cams torqued!

No more helicoils!

so then this will obviously be ready for the fall cruise.
