Re: [DML] Major preventative maintenance GOING GREAT!


Glad to hear you're growing a pair  :-)  When I went through the trouble of 
taking the intake manifold off I replaced and clean/painted almost 
everything.  I would definitely take the time to thoroughly clean and paint 
the valley.  I think I spent 2-3 days just cleaning down there so the paint 
would stick.  I then decided to use POR-15 black to paint.  I followed it's 
instructions about using their Marine Clean product as well as the Metal 
Ready surface preparer.  I would at very least use the Metal Ready as it 
will etch the surface to prepare it for the actual paint.  POR-15 is strong 
stuff, but preparation is 95% of the job.  I've got a few pictures on my 
little website that I took while doing it...

Also, be sure to use A LOT of anti-seize on any bolts you put back in, 
especially if you decide to replace those Y-Pipe bolts with stainless 
equivalents.  The aluminum and stainless will fuse over time if you don't. 
You might also decide to get really ambitious and paint the intake manifold, 
valve covers, etc. while you're in there.  I did that too, at a later time, 
still haven't had a chance to put them back on the car, though.

I can't give you a definite answer as to the vacuum switch.  I can tell you 
that mine does not spin, so I would be weary of reusing it in your case. 
They are not that expensive and considering what you would have to go 
through to replace it in the future, you might as well do it now.

When's the last time the water pump was replaced?  That's another one of 
those while you're in there jobs.  Murphy's Law seems to hover around our 

Have fun!
