That Chrysler 300 looks almost exactly like my 3.5 97 dodge intrepid
intrepid. I changed the intake manifold gasket out about 3 years ago
because cylinder 1 was misfiring. Whats funny is that I took the car to
multiple mechanics and even the dodge dealer and none of them could find
out what was causing the problem. I researched the internet and found out
that the gasket could cause the misfire. I changed it all by myself (I’m
not a mechanic by any means) and had plenty of trial and error lol.
A couple of questions for you. I used gasket sealant for the lower manifold
gasket. Did you use it? I didn’t see it on your gasket. However, your
gasket looked slightly different than mine. You had blue color around the
holes which I assume was the way the gasket was made. I don’t remember mine
having that. Anyways, the sealant that I originally scraped off clogged the
radiator so I had to change the radiator too lol. And the last problem I
had was the fuel pressure. I think the fuel pressure regulator that I
installed (new) was bad or something because when I would cycle the key to
the on position the fuel pressure would go to the correct amount and then
drop within seconds to 0. Or maybe I didn’t have a fuel rail O-ring on
their correct. But I would notice if that was the case correct? To start
the car I will cycle the key on once then off and then to the run position
and usually start right up. So I drove like that instead of taking it all
apart again and returning the regulator. Anyways, do you think the
regulator could have strained the fuel pump to make it go out. If I change
the pump I guess Im gonna have to go back and change the regulator too.
That’s annoying.
I never liked Chryslers, but I have to say for a V6 this looks pretty
accessible. The spark plugs are located in a way more convenient location
(for changing plugs and coil packs, doing compression tests and all those
kind of fun things) than a normal V6. Take the Pontiac Grand Prix you’ve
worked on, for example! I hate getting to those rear spark plugs and
wires…
For fuel pressure I honestly just take a very small screwdriver and wrap a
paper towel/shop towel/rag around it and then depress the schrader valve a
little. Probably not correct or appropriate, but I’ve never experienced any
ill side effects. Plus the paper towel or rag absorbs 90% of the gas that
might come out.
