I've noted the Chrysler/Daimler/Toyota/VW oil sludging imbroglio since it started showing up in the press, and have noted that it further depressed prices on 2.7-equipped LH cars to the point to where many seem like pretty good deals for someone with some mechanical smarts. Case in point: An elderly lady down the street owns an Intrepid with the 2.7 with only 30K miles, and her kids got ahold of the "sludge" story and are pestering her to dump it ASAP. She told me this morning, "My son says the engine is going to fall out of it soon." Thus, she said she wants to see what a dealer will offer her on trade-in, and I'm sure it won't be much.
This car is almost showroom, in and out, and has been dealer serviced since new (NOT that this is necessarily a good thing!) and she has had biannual oil changes since she bought the car in summer of '01. The door sticker says it's been using Pennzoil 10W-30, probably since the first dealer service, and there's a shiny Mopar oil filter on the engine.
I offered to beat the dealer's trade-in and pay cash, and she said she'd consider the offer. I'm looking to retire the old "grocery getter" Honda early next year, and I want to park the M-body in the garage for road trips only to keep the mileage low.
Question: With synthetic and reasonable change intervals, I don't fear the sludge issue at all, but is there anything that I should be aware of other than that, other than TCM reflashing to eliminate the "bump" shift? She claims the car gets 20-21 around town. I followed Putney's sage advice about inspecting the PCV hose, and I found it to be reasonably clean. Fingering the inside of it showed basically amber oil with a slight amount of carbonization. It does have the heat exchanger mod on it, as well...about as strange an idea as I've seen in awhile, but it appears to do the job.
I see these cars for sale all the time for less than low book, with very few going for high book anywhere. Aside from the usual LH-related problems that have been covered in here elsewhere, any caveats about this engine in particular? I found the power to be more than adequate for me and there were no outstanding codes.
