Okay, I have researched an found there are 3 ways of this method floating around to tighten head bolts on an E-Series head using an AU head gasket. I think this will clear up a lot of searching for other people.

What is the correct setting used here?

Step one;
30nm + 120deg

Step two;
40Nm + 90deg

Step three; (JMM)
Stage 1 40nm
Stage 2 80nm
Stage 3 110nm

Thanks

35nm + 90 deg is what I have always done. Why? cause it works. I didn't think this was topic that neeed clarification. Thowing the JMM stuff in there just muddies the water.

Why do you ask this?

The headbolts I picked up were ea - au and had the torque settings for both e series and a series, so I assumed it was dependant on the head or gasket.

If you use a AU heagasket us use the torque settings specified for the AU gasket.... Thats the way I've always known it to be.

30Nm + 120degrees

Done that on my car and it's been good for 4 years so far...

30Nm + 120 OR 40Nm + 90 is by far more precise than 3 different torque settings. From what I was told, the accuracy of a torque wrench changes with increase in torque and if the block was not cleaned properly with little bits of grit/shard metal in the bolt holes, the bolt can actually "stick" more giving a false torque reading on the torque wrench.

At 30 or 40Nm, the accuracy will be higher than at 110Nm while 120/90 degrees allows bolts to be tightened to equal distance.

Well that's from my understanding, and if you are a backyard mechanic, chances are your torque wrench has not been calibrated regularly and accuracy will be way off.

Alright fellas.

Reason why I ask this as I used JMM specs an leaked coolant after 6 months of high rpm drag racing. Legally.

Ford genuine headbolts are same from EA to AU. I only use Genuine. Also use genuine head gasket.

I will use the AU spec this time an see how it goes.

Got the block decked this time, so hopefully that was the problem. Or the fact I use JMM specs.

I am mechanic by trade, only fresh though. I just seen those 3 specs thrown around a lot an wanted too see who used what specs more often.


Thanks

I have always used the 40Nm + 90*.....I don't use a buffer to clean either....this tends to polish the metal surfaces and doesn't let the gasket bond properly.
Also, filling with inhibitor/coolant into a fresh engine, or just a head gasket job, will also upset the bonding of the gasket/s.
Take a look at the ACL specs for surface finish and the using of inhibitors/coolants too soon on an engine.

My engine wasn't leaking coolant, or using coolant, but I saw the corosion crystals.....that head gasket had been replaced about 3 years earlier....at a Ford dealer too.
It's coming up to 3 years soon.....and I towed a car trailer from here to Geelong and back.....no probs.

who is joe? dont sound to bright to me
ford engineers know more than your joe.
he could have been taught by jesus that does not necessarily meen its right.


You may want to bite your tongue before shooting off your mouth with inadequate info, Green Machine is talking about Joe from Crescent Motorsports, Knows more about fords and modifying them than any ford dealer in Sydney and I could safely say, Australia. For years has been getting big solid results that have been backed up with fords.

I would listen to what "joe" says over a dealership when it comes to building and maintenance.

Whats your conclusion for "Who is joe? dont sound to bright to me" BTW, awesome linguistic skills there champ. You have made your claim, now back it up.

lol!

yeah... because the guys in the dealerships are the ones who came up with 30nm + 120 degrees...


last few i've done i've used 30nm + 120degrees, but i've not heard any bad things about the JMM method either.

I'd suggest picking one of those 2 and be done with it.

the 40nm + 90degrees is typically the older e-series spec.

hold on.i was refering to green machine not being to bright he mentioned a guy named joe.who the frig is joe i dont know who joe is= joe blow joe demajio gi joe
there is probably 2000000 joes in the world. see where im coming from
i cant say anything good about cresent motorsport as i have never heard of them.
mention jesus everybody knows who jesus is
ford cam up with the method of the 30nm+120deg to coincide with the different gasket materials to over come the forever failing head gaskets.
i worked at ford between 1990 and 2000 and the amount of gasket failures was fairly common especially in the ea-el. some of them were due to broken head bolts
not until au the waranty claims on head gaskets near disappeared.


No probs, it wasn't exactly clear who you were having a dig at I gotta admit. Sorry bout going off at ya. Have a nice day.

Generally you use the torque specs of the particular head gasket. Option 1 in the OP post in this case.
The two stage method of 1st stage torque, 2nd stage angular is most accurate and consistant.

If you've searched well, you'd have found Stockstandard's extract explaining the various methods and why the later stages using angular over actual torque is better.

Hey stig you bright bastard! i only said 'joe' cause most people on here have heard of him or had work done by him,and he's been in the performance ford Ins. for 30 years so thats why i would listen to him.
And next time before shooting your mouth off try saying 'joe who' and leave it at that instead of all the s**t you went on about.
And years ago all head bolts were done in three stages, and i only said the 90degrees is only good if you use a dwell otherwise not consistant.
