A; If this happened after a over "Rev" situation ( where the engine RPM went too high ). Replace the bend push rods, if the engine still missfire do a cyl blowby check, If there is leaking valves remove the cyl head and check for bent valves, If it was not reved too high, remove the cyl head and do the clearance of the valve guides. On some engines they tend to slowly build up carbon and cause the valve to stick specially in the decellerating mode. After the engine cool down the valves will seem to be loose again. Clean the lifters and put them back after the head has being done. Frik

87 Chevy S10 28l V6 and one lifter collapsed and warped the pushrod Can you just change that one bad lifter and do you have to take off the intake manifold to get the lifter out please help?
You can change just the one lifter, however you should determine why it went bad. The intake manifold must come off to get to the lifter. Is there advanced mileage? do you change the oil regularly? Seeing how it is an 87 vehicle, with 19 years of use on the engine, I would strongly suggest changing the full set. Be carefull though as there is the possibility on that engine of 2 different size lifter bores. If yours are oversized it will be stamped on the lifter bore (not on the lifter) 0.25mm 0.5 There should also be a white paint mark at the bore.

The lifter's are all the SAME. the push rods are what is DIFFEERENT. Some are longer the the others. They MUST be put in the right place are you will bend a valve as soon as the engine turns over.
You were told that when you take off the intake you are supposed to change the oil you failed to change the oil and now a lifter is knocking Could this cause you to not have any power?
Why yes. Loss of compression in that cylinder that has noisy lifter.
