I've got a 92 Dodge Caravan with the 3.0 v6 engine and 191k miles. For some
time, the engine has had a ticking sound to it that somewhat comes and goes.
I haven't thought too much about it. Lately it seems to have 2 ticks going
on...one kinda comes and goes.
Anything to worry about? Anything I can/should do to try to stop it? If
it's not hurting anything, I'm just not going to worry about it...you expect
some quirks after this many miles... :-)
You posted this as a reply to my message deep within this thread, which is
somewhat old. If you want your issue to get noticed, I would create a new
thread with what you wrote below. You'll probably get more responses that
On a 3.0 liter Mitsushitty engine a tick GENERALLY means bad valve
guides. Usually also means you are using a bit of oil between changes?
The oil will kill the catalytic converter eventually - then you will
start to see the blue smoke.

Interesting...I hit "reply group", and cleared the message and subject
rather than doing a new post (bad habit from replying to a Yahoo Groups post
to avoid having to dig up the group address). Didn't think for a second
about it adding to your old thread since I hadn't kept any of the text!
Guess I just learned something new about usenet...
That is interesting. I guess you're posting through a web page, like Google
Groups? I prefer using a newsreader. I use Outlook Express and like it a
lot. Have the groups I'm subscribed to on the left. And when I'm in one of
them reading messages and create a new post, it automatically addresses it
to the group I'm in. Very easy.
Glad you got some replies anyway! The guys in this forum are great (and gals
too :-) ).
No...I'm using Outlook Express. I figured a reply post with blank info
would be the same as typing in the group name and starting from scratch.
Apparently not... Yes, good to get some info. Was hoping for another reply
or 2...but oh well...I'll take what I can get. :-) Yes, definitely a great
and helpful group.
Well, if you're in Outlook Express, then just click the Write Message button
at the top (or select New Message from the Message menu). Outlook Express
will automatically address it to whatever group you're in, so you don't have
to type in the group name.
Also, while in the new message, you can click Newsgroups to the left of
where newsgroup address is (becomes a button when you put the mouse over the
word "Newsgroups"), and you can select one or more newsgroups from the ones
you're subscribed to.
So you should never have to remember or type a newsgroup address again.
The noise you are hearing is a worn lash adjuster/lifter. you can replace
the effected ones and the problem will be gone.The 3.0 had valve guide
problems that would cause oil burning and smoke especially at idle. If you
have this problem you may want to repair them and replace the adjusters all
at the same time.
Thanks for the info. Is that a pretty major repair? Is it something likely
to cause worse problems if I just leave it alone? Just wondering what the
implications are. As for the valve guide and smoking issue, I thought I
read somewhere they had corrected that problem by the 90 or 91 model year?
Thus far, I've never had a problem with smoking or oil usage. The ticking
has been intermittent for a good while...
Isuzu had problems (if you can call it that, not sure if you would consider
it a true problem, or just a nuisance?) with their 3.2 v6's - lifters
ticking. They had a service bulletin out about running it for a while on
0w30 synthetic to flush things out and settle them back down. Perhaps
something like that would help? But then, I've also heard that changing a
high-mileage engine over to synthetic will cause no end of problems due to
gunk getting flushed out? Any truth to that?
I just looked back on what was done when it blew a head gasket at
162k...looks like valve stem seals was the only internal thing. They also
replaced the timing belt and timing belt tensioner.
