My 2.0 86 Mighty Max is running really rough

[FMS88]

So after looking at the valve train the half of the hydraulic lash adjusters are stuck and the jet valves were off 3 were tight and 1 was loose but I want to know if it would be better to by new lash adjusters or try and clean the old ones

The answer depends on your budget, how much time you have and the condition of the old lifters. If the lifters have no obvious wear, cleaning is fine but takes time and effort. Buying new eliminates messing with the old ones, but is an expense. Whether you go with new or cleaned lifters, you'll need to remove the rocker arm assemblies. After loosening the cam caps, stretch cut off latex glove finger tips over the rocker ends to keep the lifters from falling out of the rockers and into the engine.

One thing, the lifters that feel stuck may be the good ones. Those you can easily compress aren’t filling with or retaining oil. So they will be the noisy ones.
