M54 head bolt torque specs

ARP uses a premium grade alloy that is rated far superior to "aircraft" quality. Each stud is heat-treated topsi, ensuring complete heat penetration. Threading the studs after heat-treating is more difficult and costly as it's harder on tooling but the results are well worth the effort.

These simply are the best S54 head studs we've found for the E46 M3 6 cylinder engines, and we highly recommend them in both the racing and forced induction arena. Due to the additional clamping force between the head and block, these are IDEAL for turbo charging and supercharging!

Converting from the factory BMW head bolts to head studs makes it much easier to assemble an engine, especially a racing powerplant which must be serviced frequently and quickly! Head studs also provide more accurate and consistent torque loading. Here's why: When you use bolts to secure the head, the fastener is actually being "twisted" while it's being torqued to the proper reading. Accordingly, the bolt is reacting to two different forces simultaneously.

A head stud should be installed in a "relaxed" mode -- never crank it in tightly using a jammed nut. If everything is right, the stud should be installed finger tight. Then, when applying torque to the nut, the stud will stretch only on the vertical axis. An information sheet is provided with each set. Kit includes everything pictured -- 14 head bolts, washers, bolts and assembly lubricant.

ARP is a company that prides itself on performance and durability, no matter the application. Offering the finest engine hardware money can buy is the driving initiative at ARP and this is evidenced by the staggering amount of satisfied customers and race teams the world over.

I think one place even stated 20NM and 70 degrees 3 times loosening in between.

Here are the links to where I saw the info. DennisKing Specialist. Nov 5, 94 Portland, OR. You don't do 20nm and then 70 and then back it off and do 70 again. You do 20nm and I did this not long ago. Have fun. DennisPacMo said:. Alex said:. You mean 70 and 70?

Did you verify the bearing clearance via PG-1? Nope 20nm and then degrees in one stroke No. I was fixing a car that I needed to sell. In the S65 amd S54 engines, there is no call in the workshop manual for plastigauge as part of the repair when doing new rod bearings. Do you have the breakdown of how to determine what rod bearings you need yellow, red, blue, purple. Why not just take an oil sample. It will save you a few hours.Remember Me? General BMW Discussion. M54 Cylinder head torque procedure.

Results 1 to 11 of Thread: M54 Cylinder head torque procedure. Thread Tools Show Printable Version. M54 Cylinder head torque procedure How can I confirm the proper procedure for torquing the cylinder head on my E39 2.

And what type of oil should be used on the head bolts? Is ARP type thread lube acceptable? I am also lookig for the torque specs for the head to front cover bolts two smaller bolts at the front of the head. I have searched the entire internet for this information, and have found no specific information on the M54 motor. This must be a heavily gaurded secret. If anyone has this information, I'd really appreciate it.

I'd love to bolt it back together this weekend. I've been driving my fathers Mercury Grang Marquis for the last 2 months! New head bolts, 25 foot LBS then 90 degrees and 90 again. Angle tq. This is going to be tricky. To the right is front of engine, you will be looking at engine from Passenger side. Top row shown is intake side bolts, bottom row is exhaust side bolts.

Therefore, you will be tightening center bolt of exhaust row first, rearmost bolt of intake row last. Then go back and tighten all bolts in above order another 90 degrees exactly. Then repeat the last step, another 90 degrees. Chris Powell Racer and Instructor since, well.

Thanks for the reply, both of you confirm what I had read elsewhere. This will get me going. I am still looking for the specs for the two front cover bolts. I'd appreciate it. I have not seen this anwhere. Thanks for the sequence. I was able to get the head on, and torqued it properly. I made a cheat sheet that helped me keep track of what I had done, and what I had not. But then I would forget to check off my sheet every once in awhile.
