Hi all,
Ok this is going to take a bit of explaining.
1990 2.9 Ranger 133k miles. very clean.
Previous owner put new injectors in. But siliconed the intake gasket.
I get truck, runs weak but not to bad.
changed fan clutch (frozen), Exhaust gaskets (both sides leaking). This also when I found the dist was crazy loose. cant believe it ran, much less as well as it did.
Go to smog, HC real high, smog guy says look for vac leak.
2 1/2 cans later, I cant find a leak that would make the engine alter.
Go back and with the sniffer in we found the lower intake was leaking.
Change intake (upper and lower), found silicone and one loose forward bolt.
Thinking I found the problem.
Well NOW, I have a pinging /rattling. Sounds like a coffee can of rocks.
Consistently happens at 2400-3000 rpm
At first it sounded so bad it sounded mechanical.
Listened all over the engine and narrowed it to number 5 and 6 cylinders in the valve cover or at the intake valves. Found nothing!!!
Why I think its ping is cause if the spout conn is pulled the noise almost goes away.
Base timing is 10* with spout out.
I have put new cap and rotor, plugs, TFI.
Spout circuit is good, and no codes.
I even retarded the base timing to see if that helped. It didnt.
could it be the PIP unit?
computer is controlling timing when the spout is in.
with a base of 10* timing goes to 25* and is steady in till a throttle blip.
Timing does not change when ping starts happening.
Im dying here guys. Im out of time, money and patience.
Please help me save my little Ford
Thanks
