Gentlemen,

I need some constructive advice on remanufactured engines, especially those from Jasper and Advance Auto. Here's the scenario:

My niece is driving (uh, was driving) a 1995 Pontiac Grand Am SE with a 3.1L V6. One day in the not too distant past, she noticed the oil pressure was really low. The genius riding with her said, "no worries, you can still drive it two miles down the road to the convenience store...," which she did. She checked the oil level and found it to be at the full mark. Figuring it was gauge problem, she drove it home, with the gauge reading quite low as to oil pressure.

The engine has now developed a "noise from the lower end of the engine," as my brother-in-law describes it. The oil pump was diagnosed as being shot, hence the lack of pressure. My BIL is hesitant to put a $400 oil pump in the engine, only to find that a bearing or something similarly serious is shot due to my niece's decision to drive with minimal oil pressure.

This car has 102K on the body and engine, with the tranny rebuilt at around 40k miles. The body is in really good condition and it has new struts/shocks on all four corners, new brakes on the corners, two new tires, and a new radiator, water pump, and alternator, all within the last year.

They were thinking of buying another used car to replace the Grand Am and junk it. I told them to reconsider buying someone else's junk and maybe put the money into a Jasper engine, have it installed, explain to my niece how to read gauges and respond to those readings, then drive it 'til it drops (while maintaining it mechanically, of course).

My rational is if they took $4k and put it into a "good used car," they're gambling on not having to replace the alternator, tranny, water pump, etc., on the used car they purchase. Nope, they can't afford a new one and that Grand Am is a "known quantity," bad engine (maybe) and all.

My BIL said Advance would sell him an engine for that car for $1,500, which included a three year, unlimited mileage warranty. Jasper wants $2,163 for a reman'd engine. I'm not certain what their warranty is. Of course, they'd then have to find someone in central Illinois that has a clue as to how to install it.

Sorry for the long post, but I wanted your thoughts on this.

BTW, how would they check the current engine to make certain that it is, in fact, "shot?"
 
Even with the mentioned maintenance already done, I'd have some serious reservations about putting 3 or 4 grand in a 13 year old Pontiac.

You're probably going to spend a grand to $1500 getting the engine installed. If neither warranty covers labor for replacing defective parts of the engine I say go to a wrecking yard and look for an engine. Some of the better ones even offer installation, and some type of warranty.
 
Tell us about the "noise" in the lower end of the engine. We also need to know what is does the re-manufactured engine have done? Re-bored cyl, new pistons, reground crank, ALL new crank, cam and rod bearings, resurfaced cyl heads, new valve guides and valves etc. etc. Same question to the Advanced engine or is that one just pulled from a wreck? You might consider rebuilding your engine if you can find a reputable rebuilder. Just some thoughts. Ed
 
That Grand AM is just like a bar of soap that one day will be all used up. What you're trying to do is make the most cost effective decision you can. The junk yard engine will probably most effectively succeed in this endeavor.
Jasper is the best way to go but not the most cost effective.
Advanced buys from someone else and trust me, it's slapped together. I don't care what the advertising says, you can't leave room for Advance's profit, handling, storage, and profit for the rebuilder.
The junk yard engine can be test run before installation, comes from a wrecked car, can be had in any number of models/years, and you may be able to get some history before you select. I've done it before with good results. One we stripped down to a short block, took it to the car wash and pressure washed it, installed it and never looked back.
The key is the mechanic in all this.

Jasper would by far be the best way to go but maybe not the most cost effective for an older car. I would also second the thought of looking for a salvage yard motor.

What kind of transmissions?
 
i also concur with the reputable salvage yard engine option. for a minimal amount of money your niece should be able to get another 50,000+ miles out of the old pontiac. 3.1's are a dime a dozen. pick out a low mileage one with some kind of warranty.
 
Diagnose the noise first if you can.
The 3.1 is pretty hardy, except for the intake gasket issue.
The computer would shut the engine off if the oil pressure dropped to zero.
My 95 Olds 3.1 had a bad oil leak (oil pressure sensor itself blew); it was driven about 5 miles (mostly highway) home.
Replaced pressure senor and it hasn’t missed a beat since. Two years now.
Still doesn’t use oil, 127,000 miles. Runs like a top.
An oil pump and oil may be the cheapest way out.
The value of a 95 is about 2 grand, if that.
 
All good opinions and I appreciate your input.

I have to agree, I'd like to get into the engine that's in there now and determine what is wrong with it before I purchased a Jasper, Advance, or junkyard engine.

Re-building the current engine, if necessary, may be the way to go. Second choice would be the junkyard engine. It'd be $3-$4k to get an Advance or Jasper engine purchased and installed.

Since I'm in Cincy and they're in central Illinois, they're going to have to find a good mechanic who can diagnose what is wrong with the current engine (oil pump aside). Hopefully, he's also good at re-builds or installs.
 
My friend has a 2001 Pontiac Grand Prix (V6) and last I've seen he has about 155k miles on it. It has been running well for him. The interior has also held up pretty well on it. No major squeaks or rattles like other GM vehicles.
 
I would no doubt go for a lower mileage used factory motor. I've only dealt with Jasper when they sold reman 3.8 turbo motors, but they were terrible. Non turbo cranks and pistons, tolerances all over the place, basically about the same quality as my mother could do looking at a picture book of an engine.
 
Soy City, Pride of the Prairie, and half a dozen other names I won't mention.

Decatur, to be exact.
 
If it was my car I would cut my losses and replace the car. you can't even get the oil pan out of that car w/o pulling the engine and it comes out the bottom after you disconnect everything including the steering rack.

So whatever they do will cost them $1500+ in labor alone. Whats the car worth? Maybe 1500? I don't think putting $1500+ whatever else into that car is worth it myself.
 
At best, I'd throw a good used 3.1L in that baby. With a new set of IMGs of course! Have them ask around for a good independant shop that would be willing to do the work for them.
