Sounds like some chatter and maybe a small exhaust leak at the manifold or flexpipe on the y-pipe idleing they really sound like tick,tick,tick the fuel injectors also click.
The SOHC motors have a lot less (simpler) valvetrain than the DOHC engines
I'm not the best at valve train noises i'd rather just cut parts off of themand weld stuff bac,k on :mrgreen:
well I have sucessfully used motor flush in the past and additives as well...some will tell you not to use them. But id say if you want to play it safe, seafoam it like you mentioned new oil and filter, jerry reccomends Rotella synthetic. I use that as well. Or try going a little heavier in oil might get rid of that chatter as well...
but a tune up is always a great way to start off a relationship!...lol
Replace rearend, front pig gear oil
New Plugs Gapped Properly by you
New Motor oil and Filter
New trans fluid/oil depending if its an auto or 5spd
Grease up all greaseable fittings.
are you running stock filter box? replace filter(i use K&N cone on Cold air intake, they make a Panel stock replacement one as well) depends if you want more power or not, if not go with stock OE air filter)
this is what id do on a generic tune up. Make your list pick what you can afford. Def plugs Air filter motor oil and filter would be a must for me.
cause you never know what the people did before you as far as maintenance, an honestly i know most people dont do maintenance or if they do its usually too late
