The PRV-6 engine had problems with oil delivery, and consequently, the
cam chains wore like a mofo. Also, the cam chain tensioners are hard
to check, making the engine (you guessed it) develop problems 'later
on' in life. The blowing up bit I can only imagine is what happened to
me.

The cam chains wore considerably and broke prematurely. A borked chain
thrashing around at the front of the engine cover is quite a chore to
fix. And expensive. The 'new' cam tensioners and my dad's modification
to the front of the timing cover (and also scoring depth marks on the
tensioners as well - so we can tell how worn the chains are) makes
checking up on those little beasts a whole lot easier.

When those chains break, it's generally cheaper to just find another engine.

Note: On different odds and ends, an interesting tid-bit is that the
Ford Triton V8 and V10 are also very similar engines to our squirrelly
little PRV-6, which was initially slated by P,R,V to be a V8, but gas
shortages at that time changed their mind. While the Triton engines
have more displacement and more cylinders and more electronics,
however the guts (as far as I can tell from visiting junkyards) look
to be the same.

Also, (I don't know if this has been mentioned before) another good
thing to do if you're having problems keeping antifreeze in the
system, is install spring clamps (instead of those screw clamps) on
the engine coolant tubes right under the intake manifold. (there are
two IIRC) If (when you take your engine apart) there is antifreeze on
the top of your engine block, (and it happens to make a mess when it
gets there) run to the junkyard and grab some spring clamps off a
triton engine (which just so happens to have most everything in the
same spot, and the same size, and happens to be a far more common
engine) and it will fix the leaking antifreeze.

Also, (Boy.. i'm on a roll here) another place to get engine parts,
etc... is www.ipdusa.com and www.swedishparts.net. IPD is a tad
expensive, but good stuff, and www.swedishparts.net had dirt cheap
(OEM and others) prices (and photos) of whatever you're looking for.
Just remember the same engine (based on the research I've done on the
engine) is on a '80 - '82 Volvo 260 series car. (Different 250's I'm
sure are similar as well, but the engine production years are the same
for that particular 260 car. ('80-'85)
