I over torqued my oil valve cap... retapped it and stripped it twice... now the housing is cracked... I'm thinking to make a block and bolt on the oil filter hoising... temporary deleting thermostat until I got another one.. will it work or not? I don't know but I'm going to find out.. wish me luck guys...

Not trying to sound like a jerk, but if you over tightened that bolt that many times to the point of cracking the housing, you definitely should be using a torque wrench until you understand how much a bolt should be tightened. That being said, I don't think blocking that off is a good idea unless you know how the oil flows. You don't want to block the flow of oil.

Well.. I tried to find torque spec on the valve cap but couldn't find it... so I torque it to 14 ft but still.... anyway imo block off the thermostat will be going back to earlier n54 model without oil cooling... please correct me if it's totally a bad idea...

Park the car until you get the part. If I were you, I would get one from the wreckers. New it costs +/- 300 $. Also as mentioned above, invest in some good torque wrenches. You need them if you DIY. If you don't have $$ for tools, you have no business fixing cars, let alone owning a BMW (Indy/dealer cost much greater than DIY).

I have torque wrenches in my tool box... I just can't find the torque spec... I have the money the buy the part now but I don't want to wait for shipping... and I'm thinking to spend my money to order a rb delete plate, aftermarket (custom) oil cooler and an external thermostat... if I'm going to spend money why not spend it for better part?

But still... need to wait for shipping...

14ftlbs seems like a reasonable torque for that bolt. if you are running stock, running without an oil cooler might be ok, if you are tuned, I wouldn't.

If I were in your position I would park the car until I had the correct part installed.

I don't advise using a torque wrench when the required torque for the fastener isn't known. I subscribe to the German methodology of 'guttenenteight', and this method (knock on wood) has never failed me.

Maybe your torque wrench is out of spec. As I said, if you would've used a wreckers yard to pick that part, you would've been in business by now at a low cost. I don't want to sound like a jerk.

Not saying you should do this, but I always travel on my motorcycle trips with some JB weld. I have used it to stop oil leaking from a cracked crankcase from a spill, and not only did it make it back to Canada from Cali, it survived another 15000km until the bike got stolen.
I also used it to fix a cracked camshaft bearing journal on an old gs550 beater bike. That sucker lasted over 40000km.

I would try to glean the crap outta that with a good chemical degreaser/solvent then get as much JB weld into that crack and clamp it as well as possible. Once set, retap the threads and be off to the races. This would be just a temporary fix!!!

Thanks for good info... noted... but I already retapped it twice... the thread is already big enough.. and I bring this thing to ask for professional technicians... we all said to get a new one... but I'll try jb weld it...
