New to this group so thanks for taking the time. Did a google search and see
that everyone is well aware of the 2.7L problem. My wife's 01 Intrepid has
460 miles on the 2.7L I rebuilt in the driveway. Spun 2 rod bearings #5 &
#6. I discovered a lot while rebuilding this engine and have many questions.
Wish I'd had time to find out about the 3.2L swap before I started the
rebuild. Oh well stuck with the 2.7 and syn 5w-30 oil once the break-in is
I saw and figured out that much of the sludge problem was from oil circ and
heat retention problems that "cooked" the oil. Confirmed much of this with
some online searching over the last week. Small oil passages, and that cast
al windage tray in the oil pan can't help. The short block I put in the car
is supposed to have the increased size oil passages in the rods for better
lube and cooling. What can I do to help out with cooling this engine down?
Is there a super high detergent oil out there that will help keep this thing
cleaner? Is there an aftermarket oil cooler and is it worth it? I heard
that Chrysler went to a 6 qt oil pan. Will it fit on my 01 Intrepid, is it a
direct bolt in? Is there a slightly cooler thermostat, or would that mess
with the emissions?
Also, now that I'm sensitive to the problem, I've noticed the engine
compartment is sealed up tight as drum and runs hot, what with the cats and
everything being under the hood. For the first few hundred miles I drove
around with the support brace that goes between the strut towers left off.
You could see the heat pouring out from under the hood. It's now back in
place but I haven't put the plastic windshield trim back on yet. That still
lets a little heat sneak by on the drivers side. I was thinking of cutting
louvers into the strut support brace but that would weaken the brace. Any
suggestions on how to get that heat out better?
