Thank you so much for your fast response!
I was told that this engine is more or less "bullet proof", but before handing it over to the local mechanic I thought I'd ask here in case any red flags would come up.
The engine is a crate engine with about 35,000 miles on it, and we are still digging through the collection of receipts from the previous owner to see what was done when, if at all. Of course there is never enough time for paperwork, now that we want to take her out to play any minute when not at work
I'll put the coolant flush on the list as that should be done anyways, just as preventive maintenance. And kick the hubby to take a look at the ignition timing...
