Worst Engine/Engine Designs of all time????????

[OKSS]

Other than the pre-1978 not really good for high RPM applications, I don't think a oil leak would be terribly common. Especially since they removed an oil pathway from the Cleveland engine blocked as compared to the Windsor. Seems like an oil leak would be LESS likely.

I was talking to a guy at a car show a while back. He had a Pantera, really nice car. Said he spent $60k to get the original motor fully built, but that it still leaks oil after 5 trips back to the shop, and a couple second opinions. The last shop finally told him it was due to tolerance issues on the 351 Cleveland motors, and there wasn't really anything that could be done to fix the problem. Just something that crossed my mind that somewhat fits the subject. Does the 351 have this stigma tied to it consistently? I don't know much about older Ford engines.

Tell him to LS or Coyote swap it and be done.

[Y2KArcticSS]

I made the LS swap the world joke to him, couldn't resist But I understand he was just trying to keep the original engine with the car, while also making it a beast, which it was other than the slight but consistent leak.

[SMWS6TA]

where is it leaking?

[Y2KArcticSS]

where is it leaking?

Rear seal if I remember correctly.

[SMWS6TA]

That sucks. I wonder if it's something that could be re-engineer to use a different kind of seal.

[Y2KArcticSS]

I would hope a shop could do something like that if I threw $60k at them for an engine build

I don't as long as it's been maintained properly.

I read online all the time of people having issues with this 2.7l engine. My experience and that of many friends of mine is different. I will admit you have to go the extra on maintenance. Fluid changes, pcv, air filters, so forth. And not abuse it. It's not a high performance motor. But in my Sebring convertible, it works great for every day driving.

LOL NO. I had 5 family/friends have the motor in brand new cars back in 99-2000 and all fight motor went before 100k, the car were services regularlly, now my next question is for GTP231, as the years went on did they improve the quality of the 2.7? revised version?????

[taman76]

as the years went on did they improve the quality of the 2.7? revised version?????

I can answer that. Yes. There were improvements in the PVC system as well as some other oiling improvements.

However i have seen many older 2.7's go a lot of miles. The biggest complaint has been sludge on earlier versions. This was caused by moisture in the oil. Later much of that was resolved.

PCV valves should be replaced every other oil change. and make sure the hoses are clear.

Fluids should be checked often. Very often. If coolant has dropped there is a problem and needs fixed asap. I say don't drive it until you know its fixed. You don't want moisture in oil.

Never ever let the engine overheat. that is sure death to a 2.7

Plus bearings were known to fail. But they actually are an easy replace. Don't even need to remove the motor.

I have become pretty fluent in Chrysler 2.7, because of their bad rep. But with what I know I am confident I can keep them going a couple hundred thousand easily.

There's a difference between serviced regularly and serviced properly

Any engine that needs to be babysitted like that is a pile of shit. And anytime you start talking about how easy it is to replace the bearings and keep it going, that's ridiculous.

+1 just that simple

Besides reular quality oil changes/spark plug replacement and maybe some pcv val's here and there(that was done) please explain your "properly" 2.7 service intervals?

[taman76]

Oil change every 5-7,000 miles using synthetic oil and quality filter. Pcv every 15000 miles just ti be safe. They are not expensive. Change air filter once a year.

I check oil and all fluids once a week. But I do drive 25k a year.

At 100k expect to do a water pump, chain tensioner, plugs and motor mounts plus coolant change. Good for another 100k.

When I say babysit it, I mean basically what I am describing here.

The 2 deaths for a 2.7 are coolant in oil. Failed water pumps being the #1cause. PVC failures allow moisture in oil as well. This causes sludge or bearing failure.

Second I s an overheating situation. You overheat a 2.7 head gaskets fail causing moisture in oil and other bad things.

Only reason to replace bearings is if you found you had moisture in the oil. At that point expect bearings to fail. If caught early it’s a super easy job. I never experienced needing to do this on any of my 2.7s. But I have heard of a few who had due to not catching a water pump failure.

I personally like the 2.7. It’s smooth quiet and provides decent low end torque for my Sebring. If needing anything it’s very easy to work on.

Far easier than the LT1 in the Firehawk. Which I curse every time I need to do anything.

[5.0THIS]

I can’t believe you’re so dedicated to defending such a pile of shit. What an engineering failure.

[taman76]

We each have our opinions based on our own experiences. All I am saying is my experience with the 2.7 has been very good.

Will just leave it at that.

still waiting for "proper" service procedure's for the lengendary 2.7.........

[CJREX]

still waiting for "proper" service procedure's for the lengendary 2.7.........

Step 1: Remove bolts from engine to transmission

Step 2: Pour several quarts of diesel fuel on top of loose engine

Step 3: Introduce lit Roman Candle into engine compartment

Step 4: Video it with your phone and upload to Youtube

Step 5: Profit.

Properly serviced.
