How to prepare a cylinder head for Exhaust Valve and Intake Valve job on a Toyota MR2?

Because of the complex nature of the job and the special tools and equipment needed, servicing the valves, valve seats, and valve guides, commonly known as a valve job, is best left to a professional. The home mechanic can remove and disassemble the head, perform the initial cleaning and inspection, and then reassemble and deliver the head to a dealer service department or an automotive machine shop for the actual valve servicing. The dealer service department or automotive machine shop will remove the valves and springs, recondition or replace the valves and valve seats, recondition the valve guides, check and replace the valve springs, spring retainers, and keepers as necessary, replace the valve guide seals, reassemble the valve components, and ensure the installed spring height is correct. The cylinder head gasket surface will also be resurfaced if it is warped. After the valve job has been performed by a professional, the head will be in like new condition. When the head is returned, it is important to clean it again just before installation to remove any metal particles and abrasive grit that may still be present from the valve service or head resurfacing operations, using compressed air if available to blow out all the oil holes and passages.

Toyota MR2 Intake Valve

The Toyota MR2 Intake Valve regulates the entry of the air-fuel mixture into the cylinder, thereby sealing off the combustion chamber to allow compression to develop. In the MR2 engine, when the camshaft lobe turns, the valvetrain is actuated, causing that valve to open. When the camshaft lobe turns away from that valve, it closes. This valve opens during the intake and closes before the compression stroke and combustion. Each cylinder possesses a minimum of one Intake Valve whose timing is extremely important in ensuring combustion, power delivery, and misfire prevention. The mechanism relies on springs that hold the valve closed with about 70 to 90 pounds of seat pressure in a stock setup, while open pressure can exceed 200 pounds, and this keeps the valve from floating at high engine speeds. If the springs are weak or if there is excess clearance in the lifters, pushrods, or rocker arms, the Intake Valve can be held open too long. Such a condition can reduce power, and in some cases, will result in piston contact. A properly functioning Intake Valve of a working Toyota MR2 ensures consistent combustion pressure. Overheating or wear and tear may damage an Intake Valve on your Toyota MR2. Having it replaced will restore the performance of your vehicle. This protects Toyota's power output.
