Fastener Torque Values [Merged 3-9] value tightness torques specs specifications

[GreddySpyder]

I changed my leaky oil pan gasket not long ago and it is still leaking. I used red rtv as the gasket and ran a nice continuous bead around the whole pan making a circle around each bolt hole. I think the two mistakes I made were not waiting for the RTV to dry before putting the pan back on, and I think I tightened the bolts too much ( I ended up breaking one of them).
I'm gonna buy a torque wrench and make sure they are right this time... how much torque do the pan bolts require? How long should I let the RTV dry this time before putting the pan back on?

sequence for main caps are different.

Im doing a head gasket, and was wondering what to torque the bolts to.

on a cold engine you would tourqe 65 to 72 in the right sequence. #1 being the middle stud on the exhaust side, #2 being the middle intake,#3 to the left on the exhaust side,#4 caddy corner from #3, #5 to the left of the middle intake, #6 caddy corner from that, #7 last on the left intake, #8 last on the right exhaust, #9 last on the left side exhaust, and #10 last on the intake right side.

How do you get as far as doing a head gasket with ZERO refrence material? (Haynes/Chiltons/DSM Manuals/CDs)

Here is something I just dug up real quick, hope it helps....some.

Thanks.

To be honest i have never looked at a haynes, chiltons, DSM cd or the like. Ive done 5+ motor swaps, bunch of clutches. The only reason i ask is id like to know the exact torque they need to be.

Please note that if you are using ARP headstuds that you will need to torque to 80 ft/lb and using the ARP moly lube

also, if you are using a 1g headbolt, that the torque sequence (not the order in which you torque, but how you torque) is DIFFERENT because the 6 bolt studs are not a stretch-type like the 7 bolt is. use the above sequence ONLY for a 7 bolt..

here you go....heres a link to a complete engine overhaul it has every torque spec you could ever need..... http://www.ecanfix.com/~manualcd/index2.htm

Exactly. The 1g only needs to be tourqed once.

But the the pic of the tourqe sequence in the is correct.

 

[Scrymerr]

So I assume the above poster is correct in saying when using ARP's the torque spec is 80ft/lbs?

 

[project_tsi]

ARP states 75 ft/lbs. using their moly lube. However, I generally go a bit over that.

I got your PM, but I guess i'll post up here for the rest to see. if you are using STOCK 6 bolt headbolts, torque once, in the appropriate sequence to 75 lb/ft. oh, and don't reuse your headbolts if you're planning to. even though they are not stretch-type, it could be possible that they will not fasten as well once you remove them

ARP's are good to torque in the above sequence, but in 3 steps. 30, 60 , 80.. or whatever interval you'd like.

 

[phillabaum03]

what do you torque the clutch bolts down at? not the flywheel..


thanks

ps..its a 1g engine

 

[PaulN]

The factory service manuals say 11 to 16 FT/LBS.

 

[FourG63 97GST]

put some lock tight on those bolts too

 

[PaulN]

Yup. That too!

 

[Millerman340]

I was just working on mine this eve. It is unnerving to torque them to 14 lbs! I have a snap on digital wrench and 14 lbs just seems loose. Needless to say they are just a tad higher. Dave.

so im finally getting around to putting my engine together and when i dropped the arp rod bolts off at the machine shop they kept the instructions. now is there a different torque reading for the rod bolts with the arp hardware? also what should i torque the head bolts to with the aro harware. thanks a lot guys.

 

[project_tsi]

Head studs 75 ft/lbs. w/ ARP moly lube

Main studs 60 ft/lbs. w/ ARP moly lube

Rod bolts 43 fl/lbs. w/ ARP moly lube OR Bolt stretch .0055-.0059"

 

[blcknspo0ln]

Right on. Also, if you are not using ARP Moly Lube (Which you should, btw) then use a heavy motor oil and torque to 115 lb/ft

 

[BrokenTsi]

on the rod bolts, the torque value isnt bad to go by, but you really need to ensure the proper bolt stretch. This is much more important. Ive noticed on motors ive assembled where torque values for eagles etc is 50ft lbs, it requires much closer to 55 ft lbs for a proper rod bolt stretch. This with a recently serviced torque wrench.

 

[project_tsi]

I feel that when using new rods, then the torque value is fine to go buy. If it were stock rods utilizing ARP rod bolts/studs, then the stretch method is what you need to folow.

 

[BrokenTsi]

not every torque wrench is the same, or serviced recently. And many torque wrenches are correct within +/- 4%. Ask any quality engine builder they will go on and on about how important rod bolt stretch is

how do you measure the botl stretch

 

[cb3016]

Do you use a hi-temp thread lock or anything? i bought a 6 bolt and have started taking it apart, and plan on putting ARP through out the whole thing.

 

[BrokenTsi]

A rod bolt stretch gauge perhaps. Jegs, summit, carshop.. anyone carries em. Thatd just be cheap insurance wouldnt it project_tsi? Or is that not as important as line honing? Give mitch a call.
