FAQ: 1.8t Torque Spec List

[Sinner44]

If a Mod could please add this this the DIY/FAQ info that would be great...

ORIGINALLY POSTED BY Richard_Cranium on Fortitude:

i see these being needed at least 5 times a week here. and even though most of the forum hates me for being me and wanting this place to stay engine related only, here they are AGAIN.

someone should sticky this or put in in the FAQ.

DISCLAIMER: no children were put in harms way while making this thread.

i took my ARP/FW bolts to like 95 ft/lb. this was done in part due to the research Andy (hypothetical) did in measuring stretch, fatigue, etc. this was observed by BobQ IIRC. and i do believe it was given the thumbs up. search poortex for this info in the archives for author hypothetical.

water pump = 11 lb
oil pump = 12 lb
front main seal cover into block = 11 lb
front main seal into seal housing thru oil pan = 11 lb
oil pan = 11 lb
oil pump pickup tube = 12 lb
big oil pan bolt = 30 lb
oil pump drive gear bolt = 16 lb
oil pump chain tensioner = 12 lb
oil filter housing = 11 lb + 1/4 turn

cam caps = 7 lb
cam tensioner = 7 lb
cam position wheel = 18 lb
cam position sensor = 7 lb
cam gear = 48 lb

serpentine belt tensioner = 18 lb
shouldered bolt on large roller = 20 lb
hydro tensioner body = 11 lb
small idle roller = 15 lb
guard bolts = 7 lb with loc-tite (blue is removable)
power steering pump pulley = 18 lb
balancer = 22 lb

intake manifold = 7.5 lb
fuel rail = 7.5 lb

exhaust manifold = 21 lb
valve cover = 7.5 lb
coolant housing = 7 lb

Fluidampr/factory balancer = 7 lb + 1/4 turn
crank gear = 67 lb + 1/4 turn
alt bracket = 38 lb
water pump pulley = 17 lb

and as for the ARP rod bolts, this is for all the torque values on the ARP rod bolts. i know this is a SCAT link, but the rod bolts (2000 series) are the same. and you just have to know what size bolt you have and you will know your torque.

Manual Timing Belt Tensioner Conversion:

Timing belt should be tensioned such that the longest part of the belt can be turned 90 degrees. If it's whining like a supercharger, it's too tight. Belt tracking too far in is usually a bent / dented roller from an overtorqued nut

The tensioner nut should be tensioned to 33 ft*lbs

Note: If you have a tendency to overtorque you should use the IE manual timing belt tensioner backing plate to prevent your roller from bending.

turbo to downpipe studs: 30 ft-lb

Dog Bone:

According to the autotech instructions -

18 ft-lb on the bolt holding the whole thing together
15 ft-lb + 1/4 turn on the bolts holding hte mount to the subframe
30 ft-lb + 1/4 turn on the bolts holding the mount to the transmission (both of them)

Note: I haven't looked in the bentley, but VF's site does not mention the 1/4 turn...but Autotech does. Is it 1/4 turn or not?

Does anyone know the torque spec for the OEM turbo -> downpipe nuts?

Does anyone know the torque spec for the OEM turbo -> downpipe nuts?

oil line to turbo = 7lb
turbo bracket to turbo (nut and bolt) = 30lb
turbo bracket to block = 33lb
oil feed line to turbo = 18lb
coolant supply pipe bracket to turbo = 7lb
oil supply line bracket to head = 15lb
coolant supply line to turbo = 18lb
crankcase vent line to head = 7lb
coolant return line to turbo = 22lb
turbo to manifold = 26lb
cat/downpipe to turbo = 22lb

Reading this scares the sh!t out of me because I have reused and improperly torqued bolts ALL OVER my engine.

Rightly so!

Here's the centerpiece of my specialty tool drawer

[FTMFW]

The day before my transmission swap I picked one up. It's been a slow "repair" process. Still need to replace a few bolts though.

[Cryser]

ARP Head STUD/Bolt spec: 3 equal steps leading to 80 ft lbs (26, 27, 27)

ARP Main STUD spec: 3 equal steps leading to 60 ft/lbs (20,20,20), Torquing from the top nut main cap #3 in a down and outward spiral ending at the bottom nut of main cap #5

To install ARP head studs you will need the tool that arp sells which is a male triple square socket, the kits are offered with this tool included for like $10

threw the main stud spec in there for your thread grog since I just torqued mine yesterday, crank spins like butter =)

IE Manual Timing Belt Instructions

yea looks pretty simple out of the engine bay...

I thought changing the timing belt with this manual tensioner setup was super easy compared to the stock tensioner. I was able to slip the timing belt on the cam gear much easier, and the tensioning part was cake.

The way I did it was this...

Time the belt first of all.

Use your tension tool to turn the tensioner enough so that then tensioner is holding the belt tight'ish. Use your fingers to finger tight the nut so the tensioner keeps the tension.

Use a wrench to put ~12 ft*lbs on the nut.

Use the tensioner tool to put proper tension (90 degree twist) on the belt.

Use a torque wrench to bring the nut to 33 ft*lbs. Double check belt tension. Readjust if the belt has become too tight.

Turn the engine over by hand and double check your timing. If you're timing is off a tooth then repeat the process and fix your timing.

Reassemble.

This timing belt job was the easiest I've ever done.

Note: With my tensioner tool the edge of the nut was flat against the side of my tool. In other words, I can't turn the nut AND have the tensioner tool positioned at the same time. That is why my procedure has the two step process of snugging the nut, tensioning, then torquing the nut, then double checking tension.
