Are these remanufactured engines any good?

[Napoleonesco]

My 97 caddy deville is starting to get up there in miles and I'm thinking about having another northstar installed so I was searching the net for good deals and I came across this motor from Marshal engines http://www.autopartswarehouse.com/details/QQCadillacQQDeVilleQQMarshall_EnginesQQEngine_Long_BlockQQ19961997QQMEIG2813CW.html?apwcid=P1135867996W43b3f85c7ab9e&gan=1&apwid6Ykw2LV#desc . I was wondering if anyone had any experience with them.

I also came across this one and these are far cheaper than what GM is charging.

I am not familiar with either of those companies.

There are some members here, that have used JASPER engines.

There is also a sponsor here that rebuilds the Northstar.

Define "up there in miles". That alone is no reason to replace the engine.

High mileage is no reason to replace your engine. If you have head gasket problems, then that's an entirely different story.

Northstar Performance that Jim mentioned can rebuild your engine with new head gaskets cheaper than most places will sell you a bare block, let alone an entire engine.

Not sure how many miles your car has but mileage isn't a reason to replace the engine. Even if the headgaskets went, I would repair the existing engine. In my opinion, the only reason to replace an engine is if something damages the block such as hydrolocking the engine, etc. Otherwise, it is better to just repair the existing engine.

Accurate Engines has a horrible reputation - check out the Better Business Bureau site. I don't know they stay in business. One of the local garages said that every engine they have used from Accurate has problems and they refuse to use them anymore.

In summary, if it isn't broken, I wouldn't mess with it.

My car still has roughly the same 141,000 miles on it give or take a few from last year. It has a oil pressure problem, and I've been reluctant to do anything with it even after putting some lucas oil stablizer in it which has helped. I've noticed that while it has been sitting in the garage it does have a oil leak and it appears to be coming from the oil pan or possibly where the oil pressure sensor is seated. The car holds sentimental value to me and the body, interior and transmission are in excellent shape, but the motor is pooping on me where sometimes i just wanna be done with it and call up a local wrecking yard company and have it hauled away. I dont know exactly what i want to do.

Forget the snake oil. Have you verified the actual oil pressure? I may be (and usually is) just the oil pressure switch on the oil filter adapter.

The oil manifold plate may be the problem - it is an 1/8" thick plate that is between the oil pan and the lower crankcase. The oil pressure sensor may also be leaking where it seals to the oil pan.

To change the oil manifold plate, the transmission needs to be removed so the exhaust crossover can be removed. The exhaust crossover runs over the oil pan. Hardly a reason to replace the whole engine...
