Most cars are difficult to work on to do spark plugs . Just did my 98 Buick century , plus the wires . Dealing with chronic pain plus arthritis , fibromyalgia it’s difficult for me to work on cars . But I still do . I also did 2 front wheel bearings on this Buick , and a right side power mirror . I used to own a Cadillac deville . Was a 2002 had 98 thousand on it when it was totaled in my own driveway . Very nice car , I liked it allot . I had a bad ignition coil and a few window regulators go bad on it . Other than that nothing else . I don’t remember if I changed the plugs . As always good day to everyone at rays auto repair and God bless .

​@@edwardrobb4682manufacturers these days just love to move the engine towards the cabin firewall for "better weight distribution".

[@gregadams558]

Fun seeing you driving around town Saturday with Wife Unit. My wife was making fun of me going fan boy as we drove by. LOL

[@paulwindisch1423]

Northstars are very much misunderstood. While they would develop leaks from the factory, a competent tech can reseal them and they won't leak anymore, Whoever resealed the one featured in Ray's video took shortcuts or didn't completely reseal it. I have resealed hundreds of them and they don't leak afterwards. Several of the ones I resealed belonged to regular customers so I would see the vehicles for years after the reseal, They would still be dry 100,000 miles post reseal. Ray, those valve covers are aluminum. 🙂 Also, the blip you saw in the oxygen sensors around the 27 minute mark of the video was likely the Secondary Air Injection system changing state. The valve you had to remove from the back valve cover to replace the spark plugs is the Secondary Air Injection check valve. As always, keep up the good work!

[@RainmanRaysRepairs]

You know ur northstars sir 🫡

[@paulwindisch1423]

@@RainmanRaysRepairs I was an engine and trans tech at a Cadillac dealer from 2001-2012. 70% of what I worked on was Northstar powered. Lol The remainder of the percentage was split between Catera timing belts and 3.6L timing chains as far as engine work was concerned.

[@PseudoSpaceMarine]

If you don’t mind me asking, what materials were used during the resealing process. Was it just a new gasket, RTV silicone, or a combination of the two? I’m just curious because the Northstars received such a bad reception from what seems to be the materials used from the factory (seals and head bolts), rather than design related ones. It’s a shame because I like the look and feel of the Cadillac sedans equipped with the Northstars much more than the new stuff that they have been putting out and had they been built better, they could have rivaled Ford’s 4.6L sedans.

[@paulwindisch1423]

@@PseudoSpaceMarine As for the head gaskets, they just get replaced with factory replacements, which come with new bolts. For customer pay jobs, I ALWAYS installed Time Serts in ALL of the cylinder head bolt holes. Coupled with cooling system maintenance, this was generally a permanent repair. It didn't require ridiculous amounts of attention, just something as simple as checking the coolant level when the oil was changed and if it was low, address the reason why. Regarding the oil leaks, the oil would leak from three places, all of them very close to one another. Northstar engine blocks are split at the crankshaft center line, so the crank case has a seam halfway up. On the top of the lower half, on each side, is a channel that is machined into the face. This channel accepts the lower crank case seals. Over time these would shrink and leak. Bolted to the bottom of the lower crank case is the oil manifold. It is an aluminum plate about 1/4" - 3/8" thick that has the same type of rubber molded to it. The top side of the manifold has all the oil channels molded into it, and the perimeter gasket. The bottom has just the perimeter seal. And bolted to the bottom of that is the oil pan. The oil pan also has a channel machined into it to accept the rubber gasket that fits into it. To properly do the job, it is best to install the engine on an engine stand, turn it upside down (oil pan up), remove the oil pan, oil manifold, and lower crank case. THOROUGHLY clean everything so there are no traces of oil, sludge, sealant, anything. Like Ray says, "SHINY!" Then, starting with the lower crank case half, use grey GM Engine Sealant to fill, and slightly overfill (by about 3mm) the channel that the gasket came out of. DO NOT USE A GASKET AT ALL, only the Engine Sealant. Properly torque all the bolts. REPLACE the oil manifold. Before installing the new oil manifold, use a thin bead of Engine Sealant around the outside perimeter of the seal that is molded into the plate. Just the outside. Install the plate and torque all the bolts. Now, for the oil pan, much like the lower case half, clean it SHINY, then, again, leave the gasket out and fill, then slightly overfill, the gasket channel with GM Engine Sealant (same 3mm). Install the oil pan and torque the fasteners. While the engine is out, replace the front and rear crank seals. The latest rear main seal is very robust, as it is a two-piece design (not the two-piece your are thinking of from the old days of rope seals). The inner portion is steel and presses onto the crankshaft. It rotates inside the rubber portion of the seal. This means the seal surface never wears out on the crankshaft. Obviously, all other gaskets and seals that are affected by removal of these parts get replaced, too. Front timing cover gasket, oil filter adapter o-rings, etc. Now is also a good time to reseal the valve covers. The front valve cover has an extra seal on the driver's side. This is what seals the camshaft protrusion that the water pump drive pulley is pressed onto. These engines, internally, are very robust. They don't have individual main bearing caps. The lower crank case is one giant girdle that houses all of the main bearings. The oiling system is also fantastic. I have quite literally been inside hundreds of these (for leaks) and I have never seen one with worn out bearings, rod knocks or any other mechanical rotating assembly issue. There was only one time I had one of these engines for a mechanical failure that was not a head gasket or oil leak. It was a lady that had amassed 49,000 miles and never once checked or changed the oil. In general, the Northstar was a well-performing engine. The highest output version of the FWD engine made 295 hp and about 290 lb ft torque which was good for its time (remember, it was introduced in 1993), was smooth and quiet running, and a long block (with valve covers) only weighed about 350 lbs. The bare block I could easily pick up with one hand, as I think it only weighed about 50 lbs. Also, they love to rev. These engines are happiest between 3500-6500 rpm. They do pretty well down low, but they really sing at higher revs. Now, in saying all this, I am not trying to minimize the size of this repair. It is labor intensive. We pulled the entire powertrain out of the bottom of the car and then separated the engine from the trans on the floor. If you can imagine how it went together at the assembly plant, that is how we removed it. Engine, trans, steering rack, struts with the brakes and the half shafts attached, all sitting on the engine cradle assembly which was then lowered onto a dolly. That is how we removed them. Customer pay, we used to charge 35 hours to completely reseal a Northstar with head gaskets and Time Sert installation. On the DTS in Ray's video, we also had to remove the front fascia because the engine cradle front horns were long enough that they were sort of trapped by the bottom of the fascia. Lastly, the piston and ring design changed for the 2000 model year. The pistons received less of a skirt to reduce reciprocating mass. This caused cold piston "slap". It wasn't detrimental to engine longevity but it was definitely a nuisance. Also, the rings were redesigned with lower tension. This was done to increase fuel economy because as much as 25% of internal engine friction is caused by the rings. Unfortunately this lead to rings easily becoming stuck causing run away oil consumption. For the piston noise, GM released a new design piston which included a slightly longer skirt that had a coating on it to reduce unwanted noise. The piston rings were also redesigned to slightly increase ring tension. These redesigned parts were introduced into production engines in late 2003. So, from 2000-early 2003 (I think there was a VIN breakpoint), there is a risk that it will consume oil, although I replaced tons of those pistons and rings, so if you go looking for a car of that vintage and it was originally from the Detroit area, maybe I replaced them already. Lol

[@mattstephens8887]

Had a 2008 Buick Lucerne with 4 portholes that had this powertrain. Wife drove it to 200k miles, both kids drove it through school. 1 coil pack, wheel bearing on the front, and an entire iron mine’s worth of pads and rotors, we drove that beast to 280k miles. Not a body panel on it that hadn’t gotten up close and personal with another vehicle… In the end, took a quart every 3 days. But still started and ran, no MIL illuminated. Retired due to the original alternator dying when it was 10 degrees outside and I wasn’t about to put a $500 part in a $50 car, in my driveway, in the snow, with the knowledge of the disassembly required to change it… So, I may be an outlier but - it was a great car for us. And this is why I don’t ever play the lottery - I’ve already used up that win…

It is my opinion that the engine compartment designers should be made to work on each type and model in the field each month for a week at different garages so they can experience for themselves the joy of their designs .

like a blind man in a brothel, Ray had to feel his way around...

A quick test on a suspect O2 sensor when you have it out is to connect a multimeter across the output leads and then put the tip of the sensor in and out of butane or propane flame. When in the flame the sensor will output about 0.9 volts and when out of the flame, but still hot, the reading will drop to about 0.1 volts. If an O2 sensor tip is caked in soot and unresponsive then a kill or cure trick is to heat it up to cherry red and test it again.

Ah the old ‘Service Stabilitrak’ light. I have an 06 DTS as well and that one likes to light up occasionally. Have since bought different strut assemblies for it and some resistors to eliminate the overpriced and problem prone magneride struts that are likely the culprit. Never had so many issues with a car this new and mine only has about 41,000 miles.

Ahhh, those were the days.... Car actually looked super nice.... I had a 97 Eldorado Touring Coupe and a 2001 Eldorado Touring Coupe... I don't remember the coil on plug... I think there was a funny distributor block on the back, with like 4 coils, and 2 pins per coil... And then wires.... I think it was waste spark??? Kind of a long time ago, I don't 100% remember.... Those rear plugs were really a delight.... If you ever did them, you'll never forget how much fun you had....

With only 48K miles it should look nice. This car is likely owned by NY/NJ retiree. Unfortunately almost none of the 4.6 powered Cadillacs make it to 100K. By comparison, that Lincoln Town Car you see parked next to the Cadillac probably has 400K miles on it.

I'm of the impression automotive designers/engineers hate auto mechanics. Since the 90s, they've gotten increasingly more difficult to work on.

[@billmonroe8826]

I don't trust new parts, either, Rainman! It doesn't seem to matter if its a name brand or not. Recently I had a new Delphi o2 sensor be bad. All parts seem to originate from China!

Mr Ray, my music teacher in high school told me I have a unique voice and that I should sing Solo. So low nobody can hear me.😢

Ray, that speed rachet wrench is there a Amazon version of that wrench.

A bit painfull watching these v8 front wheel drive engine repairs as an european, since we usually have inline 4 engines. Half of the components are right agaist firewall, other half right next to the radiator. Everything is in such hard-to-get-to places. I mean many modern inline 4s are complex too, but v8 has almost everything doubled. Still awesome work Ray!

i have a 93 el my boy has a 98 el....still going strong just dont overheat one

[@TheHonestL1ar]

Most of our transverse FWDs are also i4s, some are v6s. GM is the only one I know of that stuffs a v8 into a FWD. Even Dodge, who's known for slapping a v8 into everything it'll fit into, makes all their v8s RWD or AWD as far as I know. Might be wrong, though. There's probably also some I don't know about

Murphy's Law isn't just real, so is the fact that Murphy was an optimist!

[@jimklyman9602]

YUCK! I'd be so frustrated with being a mechanic that is forced to deal with such crappy maintenance access designs (let alone piss poor seals). Hats off to you Ray for remaining sane! If I was a mechanic, I'd have refused a bunch of the stuff you have taken in and fixed.

[@oldbiker9739]

great camera work Ray . those cady's and there water pumps need a special tool lol.
