do they charge for it?
they shouldnt...but depending on the year model and where the leak is i think it could throw a code....if it is a big enough leak the O2 sensors might not be getting correct readings....Quote:

The codes were 32 and 43. 32 is the EGR code and 43 is a knock sensor error. Someone suggested that the pin connecting the piston to the connecting rods could be going out. Any new ideas?
a worn wristpin would definately make click click sounds and trip the knock sensor. is the engine way short on power? if it detects a knock it will retard the timing and kill the power. i know the pre-vortec 350's arent known for their output, but i think you would notice it. not sure how the egr works on those motors. i think its something like the old stovepipe off the manifold and enters the air cleaner housing. that could be a bad valve in the cleaner housing but not whats causing the noises.
an exhaust leak can cause the comp to throw o2 sensor codes because it will scavenge atmospheric air through the leaky spot and make the o2 think the engine is running lean. it would fatten up the mixture and hurt gas mileage and power.
what about flattened lobe on the cam?
is there an egr valve that's cheap and/or easy to replace?
I'd start there
Think you could have gotten a batch of bad gas? Maybe top off your tank and hit it with some of that octane booster stuff
so has any one heard this noise? Cause they is a big difference between an engine miss and valve train/wrist pin problem.
egr valve and cheap not so much. I think for the one for the bronco/mustang motor is like 80 bucks at horeilysQuote:

if it is a ping (bad gas) and it's that bad, and you have been driving it for a while now. it's probably not a ping anymore. if thats the case then it may be a wristpin because the piston top has burned away and its melted the wristpin. ;)
just thinking out loud, could be a spun bearing
I think it is a wristpin. I'm going to have a guy listen to it friday morning and see what he suggests. If I need a new engine what are some good places I can call around here to get prices?
ok, two more ways to troubleshoot mechanical problems:
if you suspect its a bearing or wristpin:
sounds cooky but works (usually). remove one plug at a time and crank it over or drive it around the block. when the suspect noise ceases, thats your cylinder with the bad bearing/pin
if you suspect valvetrain problems:
such as a stuck lifter or valve out of adjustment. get a screwdriver (put one end to your ear and the other to the engine, preferrably the blunt end to your ear and the sharp one to the engine), peice of hose, or a stethescope and listen to the valve covers while its running. move it along the valve cover and where it gets loudest is the problem area. i picked up a auto stethescope at o'reilly's once to see which of my injectors were stuck. they're great to have to troubleshoot engine noises. they have a probe on the end instead of the pad thing doctors have.
to get your engine rebuilt: vilas
to get a pull-out motor: doggett auto salvage (i think thats the name, the one on the SE corner of the hwy6 and 190 intersection)
to get a new engine: the dealer :flipoff3:
where are you from?Quote:

i had a head for my old 258 rebuilt at napa in bryan. they do good work, i just didnt like the guys' attitudes there.
I think someone is going to have to hear this "noise" to understand what it is. are you in cs?
until about 3. Then I'm heading home for the weekend
i'd like an explaination of that. between the guys there there's probably 50+ years of experience building engines. cooks doesnt do very good work. they cut corners and their method of cleaning a block fills the water jackets w/ shot peen, which they dont try very hard to get out. hows that for a cooling system?Quote:

I remember we were getting a couple of ball joints pressed into some 44 knuckles one time in CS and we were looking for someone to press them in since we didn't have a press. Took them to Cooks, and I **** you not, they said, "what are those?" Then, they said they "thought" they could do it, so we dropped them off, came back a half hour later and they were like, "well, we couldn't figure out how they were supposed to go in there." We proceeded to take them and walk out and drive directly to Vilas where they pressed them in while we waited. I wouldn't trust Cooks to make me a peanut butter sandwich.
