1991 Plymouth Acclaim, 2.5 L engine,120,000 miles ...engine was diagnosed with no compression in cyl #1, after removal of valve cover noticed roller rocker arm disengaged from cam and valve..... what is the best way to reconnect.....remove bolts from overhead cam, lift and reset (risk is spining of cam shaft bearing) compress spring and valve and slide back into position (risk of compressing just spring could cause locks to come detached and valve falling into cylinder) What is the best way to approach this problem?

If the rocker arm came loose, the compression should be good, as the valve on that cylinder won't be opening. If a valve spring broke, it would allow the valve to hang open, and you'd have no compression. So, do some further inspection. A valve spring can be replaced on the car, but you must have a way of pressurizing that cylinder with air to hold the valve closed while you replace the spring. Loren SW Washington

Hi: I had this problem and the cam shaft was broken. It may not be obvious that the camshaft is broken, though. bobbie
