do you adjust the valves on a 1990 v-6, 3.1 lit the same way you adjust other valves, by loosing them up, listening for the chatter and then thightening then back up, until the chatter stops?
Or is there another way?
Thanks for the help.
I guess the next question is, my 3.1 needs a little TLC. Should I rebuild it or can it be replaced with another V-6. I know the 3.1 is different then other V-6's, but what can it be replaced with, other then the small block/ big block conversion. It's going to be my daughters car in a few years, so nothing wild.
The hot tip is to go with the 3.4l engine. These can be found used in the early 4th gen f-body's ('93-'95).
Can also get the 3.4lHT crate engine from GM, about $1800. It is listed for trucks, but once bolted in can't tell that it isn't a 3.1l. Everything from the 3.1l gets moved over to the new engine (alt, intake, sensors, stuff like that).
With the crate 3.4l need to install some SVO (F*rd) 19 lb injectors in place of the current 3.1l injectors.
If an f-body 3.4l is used then use those injectors in the 3.1l manifold.
SBC swap: a lot of effort, but doable. Best is to get an entire donor car. Frame mounts, front brake line across K member, front springs, FI harness, engine compartment harness, A/C lines, alternator is on other side. Just lots of changes.
(oops, just noticed you said 'other then SBC/BBC', already typed so I'll leave it).

Thanks for the info. So if i'm correct on what you are telling me, a 3.4 is basically a bolt in and all parts will bolt up ( alt, tranny, intake, and everything else found on the 3.1).
Yes, a bolt in. The difference is like the difference between a 327 and 350 SBC. Only need slightly larger injectors as the 3.4l has greater displacement.
Just be sure that you get a rear wheel drive version (not a FWD version).
