no-just make sure you remove the pin that secures the inner guide rail. The banana rail isn't secured on the head. If the inner guide rail breaks then you will have to remove the bottom front cover to replace it so be careful.

SOURCE: Replacing the cylinder head on

Here's what the shop manual states:

30 Nm (300, 22 lb.ft)+90°+Release all bolts + 30 Nm(, 22 lb.ft)+90° In this instance you don't have a 'Torque to Spec"... you have a "torque to YIELD' In this specification, initially torque the head bolts to 22 lb ft... then turn each and additional 90°, then loosen each and REDO to the same specification = 22 lb.ft)+90° (you're actually crushing the head gasket TWICE and stretching the head bolts TWICE.

What is the cylinder head tighten torque

Have a look on this link. You may be able to find your car:


Cylinder head bolts are usually tightened to around 65 ft-lbs, depending on what the car is.

There's more than 4 cylinder head bolts... There's usually 10 bolts.
There's also a sequence for tightening the bolts:

cylinder head tightening order Google Search

When tightening cylinder head bolts do it in 'stages' and follow the sequence .. ie.. tighten the bolts finger tight first, then torque them up to about 25 ft-lbs. Wait 2 minutes.

Then tighten them to about 45 ft-lbs in sequence. Wait 2 minutes.

Do it again up to about 55 ft-lbs. Wait 2 minutes.

Tighten them up to 65 ft-lbs or whatever is recommended for your car.

Tightening in order/sequence pulls the cylinder head evenly onto the block. Waiting 2 minutes between stages allows a 'stretched' bolt to 'settle'.

What is the head bolt torque spec

Engines are designed with removable cylinder heads, so valve train and cylinder malfunctions can be separated, giving the owner a chance at making repairs instead of replacing the entire engine. When people get themselves involved in pulling a cylinder head off of an engine you know the automobile they're working on is experiencing serious problems.

Unfortunately one of the most sensitive operations is the reassembly process. In particular the head bolt tightening pattern and torque specifications. These must be adhered to or repeat repairs will likely be needed. This article reviews common head bolt tightening patterns, procedures and tips to increase the chances of success.
Cylinder Head Operation A cylinder head sits on top of the engine block forming a combustion chamber where the air fuel mixture is compressed and then burned. This component also contains intake and exhaust ports allowing the cylinder to take in fresh air and fuel then expel the burnt exhaust gases. The most extreme heat and pressure in an engine exists in this area and is sealed by a head gasket.

Compression of the gasket is distributed evenly by the strategic placement of the head bolts. How tight each bolt should be is known as a torque specification and measured with a torque wrench to assure accuracy. The order in which the bolts are tightened to that specification is known as a tightening pattern. Performing these two procedures correctly is vital to the longevity of the repairs.
Head Bolt Torque Principles Before we get into head bolt tightening patterns and procedures let's talk about the uniqueness of the bolt itself. These heavy-duty fasteners use elasticity principles in their design. The bolt is designed to be stretched to a certain point. It's this spring like property that provides the clamping force and holding power when the fastener is threaded into tapped holes on the cylinder block side. The more the bolt is stretched the tighter it becomes.

An important note about specialized head bolts is some are designed to only be stretched one time. When this is the case a service manual will indicate new bolts are required for reassembly. These instructions are also supplied to the factory auto parts department that sells the gaskets. The second thing to be mindful of is that a bolt can be stretched too far when it's taken past its tightening specification. These fasteners can take on a bottle neck shape where the threaded portion looks thicker than the rest of the bolt. These damaged retainers must be replaced.

Im replacing the head gasket what is the tourq and sequence for instillation

A torque specification is how tight you must make the bolt by using a torque wrench which measures the tightness you apply to the bolt, ensure you are using new head bolts, a reliable torque wrench, clean the threads of the cylinder head (with tap) where head bolts screw into and when installing bolts ensure they are properly lubricated. And the sequence is the order in which you tighten each bolt.
