1998 deville 4.6 northstar engine


Recommended Posts


Only you can answer the "worth it" question.

But it is not necesaary to "replace" the engine to deal with a head gasket issue. From were I sit it makes more sense to pay the price for head gasket replacement on your existing engine. The caveat is you must find a shop or independent individual with Northstar experience willing to take the time to do the repair according to GM/Cadillac recommendations. Price can vary from $2,000 to whatever the repair shop owner senses you might be willing to pay.

If you live anywhere near Lake Erie, there is a shop in Southern Ontario that has extensive experience with Northstars and a solid reputation.

But first you must decide the "worth it" question.

I would repair the existing engine vs. installing a used engine with unknown history in the car.

I agree, unless you get a used engine with low miles, THEN timesert it, its best to repair your own engine
