How to install and adjust solid lash adjusters in a 4.7 V8 WJ Jeep Grand Cherokee/Dodge
In this clip I show you how I achieved a good gap on my solid lash adjusters or also called lifters. This is a method I devised myself and can be done with only feeler gauges and some small spanners. A nice long handle screwdriver is handy also. I did this for a few reasons. I heard the rockers pop off these Power Tech and Magnum engines. This is due to worn out hydraulic lifters and lower oil pressure. This causes the gap to become bigger and the rocker which is not bolted in place but kind of floats in place to fall off. I hope by using High performance springs with a better return rate and solid lash adjusters/lifters this will not happen. As yet none came off yet even redlining it. Secondly for performance. Hydraulic lash adjusters/lifters at higher RPM compress some and this reduces the time the valve opens opening a bit later and it also closes the valve a bit sooner. It also stops the valve open by 100%. Solids dont do this giving better valve controll and that leads to better performance. There are drawbacks to this Aren't there always :-( the gap is very small and any wear opens the gap and will cause a tick. So they require adjusting from time to time. I have done 15,000klm now and there is one with a slight tick nothing bad yet. So hopefully I will find some HO or Performance cams soon and will do the readjustment then. I was offered some HO cams a while back but sadly I was overseas and missed the message. If you enjoyed my clip or found it handy please subscribe and or click like. Regards Rik
