i have a 93 ranger and 93 explorer

sometimes while driving both of them i can hear something vibrating on the top of the motor. I think it might be the lifter pushrod / rockerarms.

My ranger never made that noise untill i blew the head gasket and water got in the oil. Does anyone know what that noise is? I dont think its the bearings. Its not knocking.

Would I have to replace the lifters and rocker arms if they were worn too much? is there a simple way to end the noise?

Whats your engine size?

If its a 2.8/2.9 V6 you might want to check this out.

explorer is a 3.0 v6
the ranger is a 4.0 v6

Well anyway I have found that you get more ranger specific help over at rangerpowersprts.com than here. No offense to anyone here but it seems to be mroe help on those forums.

I doubt this is the problem, but my 2.3 was clicking when I accelerated and eventually my timing belt snapped. Still trying to get it running, but it may be worth a glance.

the v6 models have timing chains on the 3.0 and 4.0

I doubt the chain is clicking. it sounds like pushrod vibration

I got under the truck while it was running. The noise seems to be coming from the oil pan area. Now Im almost sure its the rod bearings.
