have a neighbor who had a metal timing chain go on a 68 old cutlass
years ago.. he would crank,crank, crank, and nothing.. go inside and
come back out and it would start right up.. turn it off and just crank..
the chain was jumping in and out of timing and did this.... dont know
about the noises, but i guess it would make a wining noise if loose.. i
never had any problems with timing chains......
One of the first things I was told shortly after buying my first car was
that the timing chain had slipped. This came from a fairly well reputed
mechanic. I refused to believe it so I researched it. Usually, an engine
with a loose chain that has slipped a cog will still run. You might have to
crank the rotor around a bit to make it run OK. The exhaust will lisp - if
you hold a card against the tailpipe, it will alternately blow away and then
get sucked back against the pipe. The engine will have no pep and just
sound wrong. Timing chains stretch with age and you can usually hear one
slapping around inside before it jumps. It doesn't happen very often.
Many newer engines use a timing belt. With wear, the cogs can fail and
these slip. Depending on engine design, the piston can hit the end of an
extended valve causing all sorts of damage. I was fortunate in that the
only time this happened to me, the engine was designed so the pistons and
valves couldn't touch. A new belt and the car was as good as new.
I hope this is helpful - Paul in Dayton
have a problem startng the car... pops when accelerating... was told its not
the timing chain because sometimes the car starts first crank other times it
will sit for a week without starting
would the TPS cause this?
the car doesnt have a cel since its an 88 taurus 3.0, and it says lean bank
1 h02 something and the tps out of range...
i get paid on monday, so i can finally buy the tps :D crossing my fingers
its a sensor and not the timing chain.......... the car only has 104K miles
on it. :(
Being that the engine is a 3.0, you do not have a slipped chain. The engine is
not a freewheeling engine. Damage will happen if the chain slips. The car is
also equipped with a CEL ( check engine light ) as required by federal emission
law. You most likely have a low fuel pressure condition.
could be fuel, plugs, wires, TFI, or even a bad ignition switch. A good
mechanic or a good Ford dealer* should be able to sort it out. There are
ways to read the computer codes without using the "check engine" light.
* They do exist, they're just hard to find.
