Blown Engine...Help?
Forgive me if there is a thread on this, i've searched but have not found what I needed on here. And this may seem long but Im not a mech and aren't familiar with a lot of this so Im giving all info I recieved.
So last tuesday I use my explorer no problems. I don't use it Wednesday. I go to start it Thursday and it runs but there is a loud clicking noise coming from the engine. Sounds like a motorcycle. I think hole in exhaust but there is none and you can tell its coming from drivers side of engine. I chance it and bring it to mechanic 2 miles away. They hook it up to computer and says its misfiring1,2,3 cyclinders and exhaust is lean. But the 1,2,3 cyclinders are on the passenger side. Stethescope shows sound is def on drivers side, he suspects its a lifter that has failed. I leave it. Get a call Friday he took off the valve cover on the drivers side and finds a rocker arm just laying there not attached to anything. Goes further into investigating and finds that 3 lash adjusters (lifters) are messed up. Apparently he says they are 2 pieces but are put together as one and are not ment to come apart but he was able to just take them apart by hand without effort. Is going to replace them and the rocker, told me something about checking crank shaft with caliper a for spacing and stuff and checking if any damage was done internally. Also is going to replace the lifters on the passenger side since the one side has failed prob only matter of time before they fail too. Unfort this means having to take of whole top of engine (plenum) to get to that side. I ask him why this happened and hes not to sure seems to think just wear and tear. He got new lifters that are aftermarket but they seem to be slightly longer and isn't sure if he can use them and they woulnt cause damage, needs to check with supplier.
I also told him to go ahead and replace plugs since I got 136,000 on them.
Now I was wondering if this is a common problem?
What causes this?
Will those after market lifters work or do they need to be oem?
