Im no mechanic, but i am able to fix most things. Just not familar with engine wrk. Heres my dilema. My engine light came on says misfire in 3 and 4. I was leaking coolant from overflow but was sure i fixed it. Anyways could a leak above the engine cause it to misfire like that. I had mechanic rip it down and replace head gasket.. said he had heads checked but starting to think he lied. Any known problems with this? It is a Jeep liberty 3.7 4 x4 , which i was sure someone told me was the same a s a kj. Any help would be appreciated. Just dont have any more money to put into. ... I did lose water pump at that time drove for no more than 4 miles, let it cool. Replaced water pump. Drove it for about three months with no problems, coolant loss or anything. Then out of the blue...sorry this is a little backwards.
ya i took overflow tank off was leaking on coil packs on pass isde. Two odf the three werer wet from coolant getting down in there. I hope that is all it is. Also noticed one brether line i think its called was off and cut on the end. Gonna replace both and go from there.Is it possible that that could cause misfire.
ya i started doin that .. but probably a stuipid question. If some coolant got down into the cylinders .. do i have to get it out somehow, i was thinking a bulb syringue. Or can i just let it dry out Thanks for your time!
another thing misfires said all on passenger side checked driverside middle plug which i believe is the no 4, and this was dry. Is it possible it just through wrong code since 2 of three on pass side were getting coolant in them.
ok about getting some coolant into your cylinder while the plug was out... just leave the plug out and turn the engine over thatll get rid of it.
iam not shure which bank is which on your engine but youll generally have one bank is odd numbers and one bank is even numbers (some companies dont identify them that way however)... usually your most forward bank of cylinders is bank 1 bank one is your odd numbered pistons (again some companies identify there cylinders differently)
hope this helps
haha if you cant figure it out try and sink the "maid of the mist" with it!
hey finally got the overflow tank installed ready to go, charged the battery up etc. got to hooking up oil fill line and noticed a creamy white substance in filler, and also in line going to back of intake. Like i said not familar with the technical terms. Is this normal or could it b just condensation as temp. here has dropped 20 degrees since i first took everything aprt. Do i need to drain the oil to make sure there isnt coolant in it. I did check the dipstick, and it looked great. Thanks again for your time.
