Jeep Patriot Lash Adjuster
The Jeep Patriot Lash Adjuster causes the 2.0 and 2.4-liter engines to be quiet by automatically setting the minute space between each cam lobe and its paired valve follower. The Lash Adjuster virtually functions as a miniature hydraulic valve lifter. With the help of pressurized oil, it can adjust its length according to varying conditions, nudging the valve upward and maintaining a near-zero clearance. This reduces valve-train noise and minimizes metal wear. Earlier Jeep vehicles applied solid-lifter agents, which, with some feeler-gauge tuning, would require periodic shim swaps. Later, the Patriot adopted the hydraulic style, sparing owners from routine shim swaps. Many Patriot engines within this hydraulic family have a roller-tip setup while the Lash Adjuster rides on a small bearing that reduces friction and improves efficiency compared to the flat-tappet versions that older Jeep engines had. All Lash Adjusters in a Patriot, whether flat or roller, have the same function: to translate the camshaft rotation into precise linear motion for the valve. This Lash Adjuster design is reliable and extends engine service life, allowing the Jeep to keep driving. The Lash Adjuster is a crucial component in this system.

Jeep Patriot Lash Adjuster Parts Questions & Experts Answers
- Q: What are the steps, precautions, and tools required for removing and reinstalling camshafts and Lash Adjuster on Jeep Patriot?A:Some care should be taken here as the timing system is a bit intricate and any mistake is likely to result in serious damage to the engine; it is strongly advised that only experts attempt this; where there is any doubt regarding ability, professional advice should be sought. All work should be checked for accuracy before the engine has been started again. The camshafts do not necessarily require the removal of the Timing Chain cover and the timing chain; although it has to be done if the necessary tools for removing the camshafts are not available. First and foremost, the engine cover has to be disconnected and then the negative , battery cable; a nut to the right front wheel has to be unscrewed; the vehicle should be raised on the jack stands, the right front wheel and the drivebelt splash shield to be extracted. After then, drain the engine oil and coolant and remove the drivebelt and the ignition coils and spark plugs and finally take off the valve cover. Turn the crankshaft until electrode No.1 is at TDC on its compression stroke and be sure that timing mark is aligned when timing chain is reinstalled, mark the camshaft phasers for their proper reassembly. Free the timing chain tensioner plug and pop up the plunger ratchet with the help of a pick, and to keep this ratchet, the special tool must be inserted. Slide in a chain holding tool between the two camshaft phasers, this is to ensure that during the phaser removal the holding tool is left in place to avoid 'unlocking' of the timing chain. The camshaft bearing caps are to be marked for right and left so that each one of them can be put in place in the proper direction and the bolts are to be loosened in the sequence in which they were tightened but in a reverse order. Take off the front camshaft bearing cap together with the remaining ones: first lift the intake camshaft upward and then, fix the chain to prevent from dropping. Remove the lower bearing from the exhaust camshaft journal and loosen and remove the bolt that holds the phaser on the camshaft and mark the Lash Adjusters so that you know in which position they go back in from which they come out. Check the condition of the camshaft bearing surfaces and the Lash Adjusters and, in the case of damage, replace the piece. This done by turning the crankshaft manually prior to starting the engine at least two revolutions and feel for any resistance. Screw the phasers onto the camshafts so that the marks face each other and tighten the bolts to the recommended turning moment. Submerge the Lash Adjusters in clean engine oil and then place them back in their proper position; it is also prime time to lubricate the camshaft bearing journals and lobes as well. Align the timing chain over the exhaust phaser sprocket and position the machined scribe lines parallel to the gasket surface, then install the camshafts over Cylinder Head. There should now be no turn on the camshaft and so tighten the camshaft bearing cap and bolts in the manner prescribed with the camshaft bearing cap bolts to the specified torque. Make sure that all the marks are aligned, then, remove the Allen wrench and the holding tool of the chain, and turn the engine for two times to ensure that the marks on the camshaft are lined up. Last, apply antiseize on the timing chain tensioner plug then tighten it and end the process in the reverse taking down manner.
