Torque settings for studs on nissan navara ( engine type td27) exhaust manifold? Answered

The studs that bolt the exhaust manifold onto the engine on my dads nissan navara (year 1990) with a td27 engine have broken. The engine is un turbed. What are the stud torque settings for these bolts? Thanks.

I saw some settings of 20 ft-lbs, but that wasn't for this engine, Try this link. I didn't look at it, but it says it is for your vehicle.

I think this is for a d40 engine

I've never used a torque wrench on anything other than engine internals and never had any problems. For an exhaust manifold, do the nuts/bolts up in a spiral pattern starting from the middle. Just do them up tight, then tighten again after a couple of days. The worst thing that can happen is a leak, then try again with a new gasket.

If you can break the new studs, then you're too big for me to argue with.
