It's winter, I'm a farmer, please bear with me on this OT. Has anyone had any engine oil sludge problems with this engine? We have a 99 that we bought in 02 when it was off a Chrsler 3 yr lease. We always changed oil at 3000 miles but now have major engine problems. Thanks for your imput. I'll keep you posted .

If you read the info at the site thats posted the specific range of years it leans toward is 1999-2002. The site posted a list of remedies that should be supplied to the consumer and one was for dalmier/chry to tell what later modes were done to the 2.7 which syn oil might be one. Looks like some of you posting that you didnt have any problems have/had cars before and after the years posted.

We have 150,000+ on our 2.7 Intrepid; 120 miles a day. Not one complaint here. When changing the oil though you have to read the fine print. It doesn't take straight oil. It "Has" to be semi synthetic. Heres knocking on wood but it has never even hickuped for us.

the 2.7 is getting a LOT of bad press! I have 1 in a 2004 intrepid . So far so good. Here is a link to more complaints about the 2.7

My wife traded her 94 intrepid with a 3.3 for an 04 intrepid with a 2.7 last august. The 94 had 190000 trouble free miles on the engine but the transmission went at around 120000. It ran flawlessly but she wanted something newer for her 17 mile drive to work. I haven"t driven the 04 much but the 2.7 reminds me of winding a smaller rubber band tighter to get the same power as a bigger rubber band that isn"t wound as tight. The 94 got 27 mpg and the 04, while still new gets around 22-23. I am not impressed with the new one! The old one didn"t have a bit of sludge problems but maybe it"s because it was always driven on long enough trips to warm it up well. We always use petroleum oil from good major brand sources. (NOT Walmart)

yes my stepdaughter bought a 01 concorde with that 2.7 with 62,000 and 3 oil changes later it spun 2 rod bearings. we found out this engine has a poor oiling problem. we had it fixed by an independent shop. they talked to a dealer and they told us this is a P.O.S. of a motor. she bought this car on her own. I am NOT a MOPAR man. this car had 3yr 36 for warrenty. imagine that. ENOUGHT SAID

love the car, drives like a dream, can"t see out the stinking windows in bad weather, covers over the headlights salt over real fast in winter and no headlights

if my car made it to 100k with 3k oil/filter changes on Wally"s supertech and cheepo Frams, anybodys can

i would recommend anynone that buys a chrysler product at all seek mental advise and worry about the car after you get yourself starightened out. but in all serious (yes i know i know to each tier own alright) but serioulsy to everyone i highly recommend running good engine motor flush and honestly to each his own again but i have used many different brands of flush but honestly the amsoil works the best AMSOIL Engine Flush my wifes car gets flushed every other oil change. my truck (mostly highway gets done every 6 mo. the semi gets done once a year. it does work as i ahve seen crap come out and have tore down motors that use it and those that dont. i figure it cant hurt

AMSOIL Fast Acting Engine Flush is made from a carefully selected blend of solvents and special cleaning agents that dissolve and disperse harmful deposits formed in the crankcase, cylinder walls, pistons and rings of an internal combustion engine. When used as directed, it cleans and restores operating efficiency to valves, valve lifters, rocker arms, and pistons for improved horsepower, fuel economy, and performance. Use before changing oil.

Why Clean Your Engine?

Chances are, when your engine was new it delivered the power and fuel efficiency it was designed for. But now, as your engine accumulates miles, things are happening that are adversely affecting its performance. Slowly but surely, your engine is gathering harmful deposits that will eventually cost you money.

Even though you may follow a routine service schedule, your driving conditions may be far from routine. Stop and go driving, prolonged periods of idling, short trips that don't allow your engine time to warm up, towing a trailer, the ingestion of airborne dirt, fuel dilution, water condensation, and oxidized oil will eventually cause the formation of a thick, gummy deposit known as sludge. Settling throughout the engine, sludge will clog oil passages, restricting the flow of oil to vital engine parts, especially in the upper valve train areas.

Cold engine operation due to short trips and winter driving is death to any engine. When you get it back together use the block heater when ever at 40F or less. Yes I know it will start at -20F without one. All the cold metal is busy condensing water plus the goo and acids from an inefficient cold running engine. And running it into the rankcase. Starting an engine in cold weather without a block heater and idling it for 10-20 minutes is even worse. Told this to the neighbour and he agreed. Even found and dragged out the block heater cord.And ran an extention cord out from the garage. He still never used it. 20 minutes before leaving for work he would still go out and start it and race the engine a few times as soon as it started while it had no oil pressure.

You wanna good one? I work at an automotive shop and just replaced the timing chain,guides,waterpump and valve covers on one of those pieces of s-h-i-t,Of course i had to remove heads also where it bent every frickin valve too, cost the customer about $3,000. I would push it over a cliff first!!!!! !!

Yes, these engines, and others from almost all manufactures have sludge problems. Surprisingly the first ones that this problem started showing up in were Toyotas . Service intravels doesn't seem to have much effect on the problem.

The engineers from the auto companies and the petroleum companies do a lot of testing and this still happens. The chrysler2.7 has issues beside this too.

There are a lot of things that may contribute to the sludging as have for years but the latest I've seen about the problem in these small displacement high output engines is the wide temperature range inside the engines.

And no, the best synthetic is not a guarantee that sludge won't build up. True, it's less likely. Major engine damage has shown up from this "new" sludging problem as soon as 25,000 miles.

I have no clue to the credibility of this link, but a cursory Google search would indicate that the 2.7L engine may have a problem.

Now, I have a 3.9L V-6 in my 92 Dakota with 130,000 miles and I've had one problem with it, a worn out distributor gear at 80K miles. Bill

My cousin just disposed of her Intrepid since it had severe bearing damage in the engine. Don't know which engine it had, or how well it had been maintained. They've had more than their share of car problems over the years, so I'm not ready to blame the car just yet in their case. Bill

It boggles the mind how these engineers build these motors. Do they think or care about repeat customers? Off of my list is the 4.2 V6 that was in my 98 F-150, the Crank went at 80k, and I sold it cheap. The V-6 in my 92 Voyaguer had the timing belt replaced, and the water pump which is inside, it was admitted to the Chrysler dealership, as a patient for two days as it is a twelve hour job, which came out okay. There is a reason Hondas and Toyotas are selling good these days, and Chevrolet sales have lost 30 percent , with Chevy losing 25 percent of the market share.

The engineere are not to blame; the bean counters run the car companies as well as a lot of others.

A few months ago I picked up a used 1996 Chylsler Concorde 3.3 litre V6 with a externally leaking head gasket. Car was in good shape but 160K. Paid 100 bucks for it, Put head gaskets on it which are common. Engine looked clean inside and runs great. For what I got in her(total of 550.) I can't complain.

The 3.3 liter from the older Chrysler/Dodge are different motors altogether. I just finished the whole upper half of the 2.7l in my 2000 Dodge Intrepid with 95k. Yes sir, 3000 mile interval oil changes and I"m one of the lucky ones that made it that far. Cost me about $1100 in parts and machine shop services. This motor was a all new design in 98. Chrysler did some good things with it like aluminum block, steel liners, good head design which is kinda like a hemi design. BUT, they made it a zero interference engine so when out of time valves get bent. If they would have used hemi pistons that would have been a done deal. Other stuff they done that makes you wonder are: why put a water pump inside the engine, behind the timing chain? When they go bad they weep, and now where will the coolant go? Into the oil. Just to change that you have to take the whole front of the motor apart, and almost the whole top half. The water pump is chain driven and to take it out, valve covers and intake/plenum have to come off so a cam gear can be removed to create slack in the chain. Then you get to re-time the double over head cams when you"re done. But it gets better. To keep that chain tight they put a tensioner that works off oil pressure. That little beauty mounts through the block and pushes on the chain. The oil passages aren"t big enough for proper oil flow, it gets hot (they have computer temp set too high before fan kicks on) oil breaks down, gets thin, pressure loss, then chain slack and guess what next. And speaking of heat, wouldn"t you want to keep that moter cool? Guess Dodge didn"t so they put the catalytic coverters on each side and bolted em" right to the manifolds keeping all that heat right in the engine compartment. I was told that they are recommending 2000 mile interval oil changes on thses motors now. A good friend that did the heads told me this was originally a Ford designed engine and that they sold it to Chrysler. Don"t know how true that it is. Sorry this got so long. I had an older Dodge with the 3.3 and it was good. My wife really likes the styling and the do drive good. However, this one is going bye bye now that it"s running good and no more Dodge"s. Good luck to you with these 2.7"s, you"ll need it.

That sounds alot like they copied GM's Quad 4 engine. Water pump driven by timing chain inside of engine,and the oil pressure tensioner.
