How much torque do I need for an exhaust manifold?
Torque the LS1’s exhaust manifold bolts in two stages. Torque all of the bolts to 11 lb.-ft. on the first pass and 18 lb.-ft. on the second pass. The exhaust manifold heat shield bolts go on at 80 inch-pounds (not foot-pounds), the pipe-to-manifold bolts go on at 26 lb.-ft. and the manifold pipe nuts spec out to 26 lb.-ft. 00:00 09:12

How do you find the exhaust manifold on a car?
To locate the exhaust manifold, trace your exhaust pipe to where the round pipe bolts to a two-bolt connection near the engine. The solid structure to which the pipe is bolted is the exhaust manifold. Installing a manifold requires careful torquing of the bolts. Every vehicle has different levels of torque necessary to properly tighten its bolts.
Where do you tighten the nuts on an exhaust manifold?
It’s important to secure both sides of the Y-pipe simultaneously. Begin by tightening nuts down in a rotating sequence between both pipes. It is also necessary to alternate between both flanges found on the Y-pipe. Typically, the tightening sequence begins in the middle of the manifold while working your way out evenly between both sides.
How to get rid of stuck exhaust manifold bolts?
Learn how to remove stuck exhaust manifold bolts or studs. Wades shows you a little-known trick to help loosen up some of those old, seized and corroded exhaust manifold bolts. This can be a life saver tip and is a very common problem for gas and diesel applications.
Is there a leak in the exhaust manifold?
There is no audible leak sound (tapping) at idle and when revving. When driving there is a slightly “hollow” sound at high revs. I do smell some raw exhaust intermittently. However I think some carbon may have sealed up the leak.
What are the torque specs for a B Series car?
B18B,B16,B17,B18C Following the manufacturers recommended torque sequence, tighten the nuts in three equal steps to 30ft lbs,60ft lbs and then 80ft lbs with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT. Shown above is one cam cover, sequence is the same for intake and exhaust cam cover.
How much torque does a LS1 engine have?
Torque the LT1’s exhaust manifold nuts and bolts to 30 lb.-ft. Also known as the Vortec, this engine was a clean-sheet design that shared not a single component with the original small block. The LS1 is a thoroughly modern engine, easily as advanced as anything on the road today and requires a whole new set of maintenance procedures.

What are the torque specs for a corvette?
GM introduced the second-gen LT1 in the 1992 Corvette as a modern update to the original small block. Most of the LT1’s parts interchange with its predecessor’s, and bolt torque specs are similar. Torque the LT1’s exhaust manifold nuts and bolts to 30 lb.-ft.
What are the torque specs for a botl manifold?
Again depending on the grade of the bolt, torque specs will vary. Here’s a link: Botl Torque by Grade I believe the bolts are 10mm x 1.25mm thread count. Might be 1.5mm thread count. As for the sequencing. Start in the middle of the manifold and work outward, alternating side to side. Also move in steps to your final torque setting.
