Ordered my 4.6 liter code-9 engine Saturday morning from Northstar Performance. $3,950 plus a few hundred shipping. It is due early next week. Have tried several times to post some pics, but after jumping through all the hoops all that comes up is "internal server error." Will keep trying. Did find a good place for Aurora parts out of Wisconsin. They are called Rockauto.com. and while they don't have everything, they do have a lot. Actually found both pre-formed P/S lines for about $40 bucks.

Check that. Here is the exact error code: Error 500 - Internal server error. Even made sure the correct address was up :imagehost.auroraclubna.com/ All I get when I click on that site is another message that "this page cannot be displayed". . . And so it goes.

Wednesday afternoon 7-17. Just received new motor from NorthStar Performance. Expected it to come in a crate secured to a pallet, but it was just wrapped in plastic. Still, it arrived in perfect condition. However, my efforts to post a picture have once again proved fruitless. I follow the instructions to the letter every time and all I get is the same error code. This is so frustrating. Would one of my new Aurora-friends consider posting these pics if I provided them via email? I don't know what else to do . . .

Wednesday 07-24-2013 Well, all the parts are delivered, boxes are everywhere (GM reneged on honoring the lifetime warranty on my ignition wires) and it is all in the hands of the mechanics. They are juggling my car with a vintage Corvette in the next bay getting a crate engine. Today's first order of business is the installation of new brake lines inside the engine bay. Changed my mind about putting the Aurora valve cover on Cadillac engine. It just looks too good the way it is. Also plan on keeping the original engine.

Been working with Northstar for years and I know if you are using 10-30 oil in the summer and you have 95 degree days your idle oil pressure will fall below 10psi in all Northstars. The fix is simple, drain the oil and replace it with 20-50 weight oil and replace filter. I always use Wallmart brand oil and it is cheap and I have engines with over 200,000 miles using this cheap oil. Change it every 3000 miles. I bet the alarm will stop.

Went over for a brief visit with my car Friday. Despite it convalescence, it's spirits remain optimistic . . . the new engine is still awaiting installation. As the owner/lead-mechanic is down with a back injury, everything has fallen on the shoulders of John, the other mechanic. To say John is swamped is to understate the situation entirely.
He did get the new brake brake lines installed last week, but that is about it. With no other options available, I remain patient.

08-09-2013 - Made my now-weekly visit to see my Aurora yesterday. The transmission is installed! And an exhaust manifold along with the oil filter housing! Which begs this question: He had to use the oil filter housing off my old engine because the new Cadillac engine has an external oil cooler, which the Aurora does not. Is there a reason for that? Does this engine, being of higher horsepower and greater torque, need one? It came out of a DeVille, which I assume is somewhat heavier. Has anyone added an external oil cooler to an Aurora? Any ideas, comments or suggestions on this matter would be greatly appreciated.

No. All 95-96 Auroras have engine oil cooler and some 97s. I'm not sure what models of the 4.6L cars had the oil cooler though. It isn't necessary but it certainly doesn't hurt. It's also four more places to leak oil too. I swapped filter adapter on my '96 to '98 adapter and deleted the engine oil cooler lines. No change in anything for thousands of miles. You're safe!

Monday 08-19-2013 Made weekly visit to my Aurora in exile Friday afternoon. Not a good week. The new P/S lines and sway-bar links are installed . . . that's it. Decided to go ahead and pull the PCM and send it off to Madtuner. I don't know how long the turnaround time is, but I doubt that will be an issue.

Sunday 08-25-2013 Sent my PCM off to Madtuner last Monday. The shop said they were bringing in more hired-guns to free up my mechanic so he could work on my car. Lo and behold, a Thursday visit to the shop proved they weren't kidding. John had the engine pretty much all back together. Friday afternoon it was back in the car, though much remained to be done. Thanks to Renaldo613 for his help in posting these pics.

Friday 08-30-2013 PCM arrived today, 12 days after mailing it off to Madtuner. Left it over to the shop in Farmersville. That's right - Farmersville. Everything is in place now for a really big week next week. Will keep my fingers crossed . . .

Wednesday 09-04-2013 Complete Auto finished installation of my NorthStar Performance engine yesterday. It started right up and they began break-in procedures - running the engine for short periods of time and shutting it off, then letting it cool off completely.
They contacted me this morning with an issue of which I am well acquainted. There is a relatively high amount of top-end chatter coming from the valve train. It seems as the engine warms up, the oil pressure drops from a high of 75 PSI (with virtually no noise) down to 10 PSI. As the oil pressure drops, the chatter increases as if it is starving for oil. They are very concerned. At 10 PSI (on a mechanical gauge), they shut the engine down. I explained 8-10 pounds on this engine is within the normal range.
Their cause for concern lies in the fact that this is a new engine. Valve train noise at low rpm on a motor with 100K miles is understandable, but on a re-manufactured engine? I need to find out how low the oil pressure will drop before it bottoms out but do not want to risk damaging the engine if something is indeed wrong. I need help from the experts at ACNA. What is your considered opinion? Should I proceed? Is top-end chatter common to the Northstar engine? I have contacted NorthStar Performance, but a response usually takes a long, long time.

Hmm interesting. Sounds like it needs thicker oil. Try having them put 10W-40 in there. If i recall correctly someone else on here replaced there engine with a rebuilt northstar, and experienced the same issue. The valves chatter awfully loud initially, but you gotta let the oil circulate threw out the entire engine. My engine never bottoms out at 10psi, i usually hover around 20-30psi at idle.

This is a re-manufactured engine with a 5-year 100K warranty. After saying it took a long, long time to hear back from NorthStar Performance, they responded via email within two hours stating, "Everything is fine, it'll go away in time." Comments, anyone?

I had my engine rebuilt with a 3 year warranty. After 2/12 years I got lifter noise. The pictures in my previous post show the rebuilder honoring his warranty and putting in new lifters and pistons. The original rebuild did not include new lifters. My suggestion to you is to ask them if they used new lifters.

09-08-2013 Sunday night. Sorry for being so slow to respond. I have not had a chance to ask about the lifters. Called NorthStar Performance Thursday morning, but once again they did not answer. So I called the shop and told them about their response, "Everything is fine, it'll go away in time." They took it up the road for a short test drive. I emphasize the word, "short." 7,800 feet up the road he turned around and limped home, shutting it off as he pulled in. The same old problem which plagued my old engine of 135K miles - chronic low oil pressure. By now I am beginning to sense a deep, grinding, churning sensation deep in the depths of my bowels . . . My worst nightmares have come true.
This time Jake did answer his phone and had a worse reaction than I did when told of the news. Yeah, it did get heated. He said he was coming to the shop one day this week to see the car for himself. He firmly believes the engine he sent us was fine, but I cannot think of anything we could have done to cause an internal oil pressure failure. We even changed the oil filter, to no avail. I have sent a PM to all the big kids (45) at ACNA. I really don't know what to do next. I am afraid things could get very ugly, but it is what it is and I intend to meet it head on.

THIS IS NORMAL. I'm telling you it will go away. I had the same thing with the engine i swapped in a 96. change the oil with 5W30 and continue the warm up procedures!! It will quiet down, the engine i changed took a LONG time to stop the top end chatter! These engines have SMALL oil passages and it takes a while for the lifters to pump up! aurorah.proboards.com/index.cgi?board=1stgen&action=display&thread=24729&page=2

09-12-2013 Thursday morning After exchanging emails with NorthStar Performance over the last few days, Jake has instructed my mechanics to tighten the bolt on the harmonic balancer to 250 ft. lbs. This is to insure the new oil pump is not slipping. If it is slipping, wouldn't it do so throughout the entire warm-up period? I would think warming it up would expand the metal and thus make it tighter at higher temperature. When it's cold, the engine has normal oil pressure around 70-75 psi.
I will ask him next time we speak if the lifters were replaced. If this procedure yields no positive result, we are going to re-install the Caddy oil filter housing after installing a loop, since my Aurora does not have an external cooler. After that . . .
