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?

thanks for the fast answers guys!!

A rod bolt stretch gauge perhaps. Jegs, summit, carshop.. anyone carries em. Thatd just be cheap insurance wouldnt it project_tsi? .

Of course it would be. However, don't you trust a company such as ARP to provide adequite torque specs to use with there moly lube? The ARP moly lube is used to precisely duplicate all ARP fastener preload specifications. If you can't trust a company with there lube about there preload specs, then I guess we can't trust ARP for the stregth of their bolts/ studs either.

Trust ARP? well the first set of factory sealed head studs I got was missing one nut. They sent me a replacement set (luckely I kept the first set till I received the second set) and it was missing a stud and one of the nuts didn't have any threads. I hope their research department is better then their quality control

 

[90turbotsi]

Mine were missing the washers and the assembly lube ohh well its cleared up now but yea I agree with the fact they need to check what they are shipping out.

Daren, I must have gotten that missing nut! In my new set of ARP head studs, I had 10 studs, 10 washers, and 11 nuts, and everything else.

Funny tho, I have never had any shortage problmes w/ my ARP hardware, head studs, main studs, rod bolts, etc.

Hmm well I must be special becuase I got 2 packs that were short something

Its got nothing to do with trusting ARP with their torque spec. Its the fact not every torque wrench is trustworthy IMO, and torque value is strongly affected by the "smoothness" or surface finish of the threads on the bolt and the threads in the rod, the type and amount of lubricant used on the threads etc.

Bolt stretch is affected by material properties and bolt dimensions. Its just absolutely more precise.

Never once did i say you cant go by just torque value. But in my personal experience, i will tell you, its not too often im dead on with the bolt stretch with the recommended torque values. And ask ARP and they will tell you, bolt stretch is a much more precise and correct way for measuring preload.

What do I torque my fidanza flywheel down to on my 6bolt
Need to know asap last thing holding me up

thank you

[project_tsi]

96-100 ft. lbs. Torque in a star pattern, just like a wheel lug. I generally torque in steps of 3. 33-66-100, or close.

 

[Birt96gst]

thank you

 

[antlip]

does anyone know the torque specs for the valve cover on a 95 gsx eclipse? and do you use any kind of sealent with the gasket or on the threads for the bolts that hold the valve cover on?

 

[billys90tsi]

Its 2.5 ftlb. I dont use a sealant but gasket seal works ok.

 

[mavisky]

I always put a very thin layer of rtv on my gasket and for god's sake just snug up the bolts. The torque specs are literally like 5-6 ft/lbs but trying to get your torque wrench to work at levels that low usually means you'll overtighten and crack the valve cover.

I'd advise using a 1/4" ratchet just to keep from getting all gung-ho about tightening the holy hell out of it.

 

[PieEyedPiper]

^^^
I just tighten mine to "snug". Cracked valvecovers aren't much fun.

 

[No_Skillz]

I put some RTV on both sides of the gasket. Wait for it to DRY before you drive and change your oil.

 

[GVR4592]

Putting rtv on a rubbber gasket defeats the purpose of the gasket and is more likely to leak. I never use rtv on a gasket and I never have any oil leaks.

 

[speed127]

Now i'm not looking for an argument and true I own a GS BUT the shop manual says to put some gasket sealer on the inner lip of the valve cover before you put the gasket into it. I"m guessing it's more to hold the gasket in place but I have always used it, even on previous cars, and haven't had a leak to this day.

 

[mavisky]

I use RTV because I'm re-using a gasket that's been on the motor for the last 4 years and has been off 10 or more times as I change between valvecovers.

Mav, the spec for a 4G63 cover is 2-3 ft lbs. If you have a good gasket no RTV is requires to make it seal. The FSM calls for some in the corners where the cam caps meet the head for a long term seal.

Yep..like the manual says, only put RTV in certain spots.

For tightening, I just take my 10mm socket (JUST the socket..no wrench), and finger tighten the bolts with the socket.

 

[kenamond]

My Haynes manual doesn't include the torque specs for the 5 transfer case bolts. I searched and found one thread mentioning 40-43 ft-lb, but this was in reference to a Galant. I don't know if it's the same for a 2g, and I want to make sure.

Funny how the manual says to torque the bolts to the specs listed at the start of the chapter, but doesn't include them there. I imagine there are other ommisions - like not pointing out that the two shorter oil pan bolts must go under the timing belt or you'll shred the belt and total your valves. I'm glad someone pointed that one out to me.

Thanks!

i just installed a mls cometic headgasket with arp head studs. its on a 6 bolt motor. 1g head. i need to know torque requirements. does anybody know a link for the step by step for a headgasket install.

 

[GVR4592]

Do you have the moly lube that comes with the ARP's? Or the instructions that came with the ARP's? Did you already install the gasket?
