Knocking

Running Project said:

All right this is flipping crazy. I have an 88 cherokee limited 4.0 I6. Now it was running really good after shoving a bunch of lucas oil injector clearner through it after it sitting for 2 years. So i just take it down to get emissions (which it passed very well) not i got this loud knock in the engine at idle.

:rof: Must be my twin. That's exactly what had happened to mine b4 I purchased it

The thing runs great when not at idle, but here is the craziest thing. It does it on and off. I think i need to replace the motor mounts because of it being unbalanced. Also I have noticed that my oil presure gauge peeks over 80 off and on, but usually sits at 25 or so.

I had the same knocking at idle which went away when driven - Found out after many exhaustive attempts at different so-called "Jeep Specialists" in London, that told me it needed a new engine. After a HEAP of help from the guys here on the board, (and thanks to EDM in Bicester UK) it was found to be the bolts for the flex-plate which were loose, coupled with a cracked flex-plate.

also got an issue with my fuel gauge going up and down when turning left and right. I had just taken the tank out to replace the o-ring on the pump because it was leaking.

The gauges is probably a bad earth, but I'm sure someone else maybe able to shed more light

Another thing, I have a nice little thumping in the back were the rear shocks are. The guy i bought it from had wood screws holding the shocks in and the holes were rusted out and stipped. I retapped them and put much better screws in (grade 8) and they are tight as tight could be. I think the shocks are what are causing the thumping not really sure

As for the shocks, they're probably well past their use-by-date

:windows: -vista is a knock off apple product !!!!:twak:
