'84 944 head torque specs

Looking for torque settings for 1984 944. The manual we have states varies by year and then becomes non-descriptive. Someone with some experience is sure to know...
Please help.

Thanks in advance.

Brent

first, i am pretty sure that if you PRINT OUT the sequence and procedure given at clarks-garage.com you will find the exact specs you are looking for. as i realitycall, when i did mine, the specs using a wrench of torque are given up thru 1986, then you use torque angles on the 1987(mine) and up models(some exclusions apply to models other than the normally aspirated 944).

i did not know what torque angles were, but here(pelicanites) i was taught that you use the torque wrench for the first tightening sequence, the you use the torque angle, (90 degrees of turning each bolt) in two tightening procedures, one after the other. I allowed a period of time (overnite) between each of these torque angle tightening sequences.

the main idea in torqueing is to
1) tighten the head equally in all areas(usually from an inside region towards the outside region) this is evident by the numbers in the tightening sequence, lower numbers inside, higher numbers toward the ends.

2)you don't want to stretch the threads out by over tightening like my brother does. you want to use the strength/grade of the bolt to its useful pull using the inclined plane (the threads) that is why the threads are somewhat fine, not coarse. some people use new bolts, but i did not. very close inspection of my bolts did not reveal and previous overtightening and stretching of the threads.

i also used a ballpiene hammer to gently tap the head and bolts as i torqued her down to insure no sticky areas, misalignment of head, head stuck on a thread, etc.

don't be in a hurry, and be very clean on the threads(inner and outer of block and bolts), and all surfaces. use great care to ensure that NO wires, sensors, fingers, dirtballs, etc are under the head when you place it on the block.

mie was driven hard from k.c.mo. to denver and back the following week, and still purrs like a lion.

keep us posted, and welcome to the board.

step 2) 37 ft lbs
step 3) 66 lbs

don't forget some tapping while you are doing it, and let the head "settle" for a period of hours between step 2 and 3. temperature fluctuations allow expansion and contraction of the aluminum head.

Thanks for the assistance as my son is eager to return to the streets. (I've got him driving the minivan to school) Wonder what the social ramifications that created...

Updated torque specs...

Should be.

1. 15ft/lb
2. 90 degree turn
3. 90 degree turn

I wait at least 15 minutes between each step. (but I am always in a rush)

I find it gives you around 75 ft/lbs .....

Edit... Tell me thats not a turbo badge on the back of that NA.

Yes that's a Turbo badge... My son is a dork. However, It is his car and eventually my purist attitude might wear off on him.

Put a little oil on the head studs prior to torquing as well.

Is it paranoia if everyone really IS out to get me?

TSNAPCRACKLEPOP is right for the '84. Three stages, 15, 37 and the 66 lbs torque. Wait between each torquing - Clark's says about 15 mins, which is what I did.

ae1969 is right for later cars.

.... the later torque spec is actuallly supposed to supercede the previous one......... It was a tech bulletin

But both specs will work. I have used both...

That is for the 2.5 L NA 8 V

No kidding? Interesting. Do you think torquing would be more or less accurate than measuring degrees? I wonder why they suggest this. I did my head just this week - got the machining done for $150, which I figured was pretty good, and it took me about three evenings to get everything back together. Did all the vacuum stuff while I was there. I actually picked up a head set from Punch Buggies, but the manufacturer shorted the pack by one exhaust gasket. Haven't told Rob yet. While I was on the phone with him he tried to sell me the 84 944 he's got there. Have you seen it?

I found out that it is possible to get to one of the breather hoses under the manifold from under the car... :>) But I have a strange new bend in my wrist...

Hey brentw2 - let us know how the job goes! It's quite exciting to stand over the motor while bleeding the cooling system, listening to the lifters clatter away like Sten guns on speed, shrouded in the clouds of smoke burning off the exhaust...

oil on the studs, or gray anti seize, or blue anti seize? i think i used blue on mine. i think small fluctuations in the final torque can exist, but the even-ness between all the studs (all of us porsche studs???)is important for uniform expansion and contraction.

Actually degree torquing is more accurate. There is a long winded explanation for this ....but lets just say it is.

Nope havent seen that 84 ?

So what is the accepted position on letting the head sit?

I'll hopefully be putting the head back on my car next weekend. Do I really have to let it sit for hours between stages, or is 15 minutes acceptable?

i would feel pretty safe doing it all at once as long as there was a tapping procedure being used during the tightening. i am sure that when the racers put theirs together, they do not let it sit for days while their friends drink all the beer in the frig. they would run out of beer, and fast. also, i bet they do not do this at the factory. in fact, i bet it is all a bunch of hogwash that we use to spend more time in the garage!!
