Are there TTY bolts on a GM LS engine?
On a GM LS engine, the cylinder head bolts are TTY and cannot be re-used. The connecting rod bolts are also TTY, but can be tightened up to three times for bearing checking.
What are the features of a Chevrolet Venture?
The LS came in both short and long wheelbases, and offered aluminum wheels, a varied seating configuration, adjustable head restraints, side airbags, power windows (optional on the base models), and a remote keyless entry system.
Can a TTY fastener be used on a LS engine?
The connecting rod bolts are also TTY, but can be tightened up to three times for bearing checking. The balancer bolt is also a torque-to-yield fastener. The intake manifold, rocker arm, and rear cover bolts can be reused. The vertical main bolts can also be re-used, but the side bolts are often replaced because they have sealant on them.

What do TTY bolts do on an engine?
TTY head bolts are common on engines using aluminum heads and/or multi-layer steel head gaskets. While all bolts experience some amount of stretch during torquing, TTY bolts are engineered to stretch within a controlled “yield zone.” Once they reach this zone, they spring back to provide a precise level…
Can a vertical TTY bolt be re-used?
The vertical main bolts can also be re-used, but the side bolts are often replaced because they have sealant on them. These can be re-used if sealant is re-applied. It is important for TTY bolts to reach their controlled yield zone for the most consistent clamping force, so the installation procedure becomes critical.
