Owners of the BMW 3 Series (E46 models) have been reporting cracks and damage in the rear subframe area of their vehicles. The issue was also common on the earlier 3 Series models and unfortunately, have reoccurred with the E46 from 1999-2006. This issue specifically appears in the rear mounting points of the subframe, which can tear out from their position in the sheet metal. This occurs as the rear differential transmits the torsional load from the engine through the subframe, and then, into the chassis of the vehicle. This constant abuse leads to fatigue in the metal, causing cracks and separation from the chassis.

From Wikipedia:
Messier 63 or M63, also known as NGC 5055 or the Sunflower Galaxy, is a spiral galaxy in the northern constellation of Canes Venatici with approximately 400 billion stars. M63 was first discovered by the French astronomer Pierre Méchain, then later verified by his colleague Charles Messier on June 14, 1779. The galaxy became listed as object 63 in the Messier Catalogue. In the mid-19th century, Anglo-Irish astronomer Lord Rosse identified spiral structures within the galaxy, making this one of the first galaxies in which such structure was identified.
The shape or morphology of this galaxy has a classification of SAbc, indicating a spiral form with no central bar feature (SA) and two moderate to loosely wound arms (bc). Each arm wraps 150° around the galaxy and extends out to 13,000 light-years (4,000 parsecs) from the nucleus.
M63 is a weakly active galaxy with a LINER nucleus – short for 'low-ionization nuclear emission-line region'. This displays as an unresolved source at the galactic nucleus that is cloaked in a diffuse emission. The latter is extended along a position angle of 110° relative to the north celestial pole, and both soft X-rays and hydrogen (H-alpha) emission can be observed coming from along nearly the same direction. The existence of a supermassive black hole (SMBH) at the nucleus is uncertain; if it does exist, then the mass is estimated as (8.5±1.9)×108 M☉, or around 850 million times the mass of the Sun.
Radio observations at the 21-cm hydrogen line show the gaseous disk of M63 extends outward to a radius of 130,000 light-years (40 kiloparsecs), well past the bright optical disk. This gas shows a symmetrical form that is warped in a pronounced manner, starting at a radius of 33,000 light-years (10 kiloparsecs). The form suggests a dark matter halo that is offset with respect to the inner region. The reason for the warp is unclear, but the position angle points toward the smaller companion galaxy, UGC 8313.
The distance to M63, based upon the luminosity-distance measurement is 29,300,000 light-years (8.99 megaparsecs). The radial velocity relative to the Local Group yields an estimate of 15,200,000 light-years (4.65 megaparsecs). Estimates based on the Tully–Fisher relation range over 16,000,000–34,000,000 light-years (5.0–10.3 megaparsecs). The tip of the red-giant branch technique gives a distance of 28,930,000 ± 950,000 light-years (8.87 ± 0.29 megaparsecs).
M63 is part of the M51 Group, a group of galaxies that also includes M51 (the 'Whirlpool Galaxy').
In 1971, a supernova with a magnitude of 11.8 appeared in one of the arms. It was discovered on May 24 and reached peak light around May 26. The spectrum of this, SN 1971 I, is consistent with a supernova of type I. However, the spectroscopic behavior appeared anomalous.
The Heart Nebula, IC1805
From Wikipedia:
The Heart Nebula, IC 1805, Sharpless 2-190, lies some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. This is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes.
The very brightest part of this nebula (the knot at the western edge) is separately classified as NGC 896, because it was the first part of this nebula to be discovered.
The nebula's intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars known as Melotte 15 contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass.

An advantage of the subframe construction is that there was a little bit of room left in the middle. Perfect for a replica engine.
I have combined subframes from three nights in October and December to come up wit this image of NGC 772, a single armed galaxy 130 million light years away. Per Wikipedia, this galaxy is twice the size of our Milky Way. Southwest (lower right side) of the galaxy, you can see what appears to be a large oblong star -- that's dwarf galaxy NGC 770, which is said to be responsible for the unusual elongated shape of 772 through gravitational interaction.

Imaged with Starlight Xpress Trius SX-9C; stacked in Nebulosity, processed including Richardson-Lucy Deconvolution in PixInsight, and finished in ACDSee. 41 exposures of 5-8 minutes each from 3 separate evenings were stacked to form this image, taken from my yard 10 miles north of New York City.
While he was waiting for the guys to prep the body, Dave started assembling the various components and then the subframe, which holds everything forward of the firewall. This will let him bolt this subsystem to the tub and mount the bonnet, and have all the little pieces already in place (and in the correct order).
He pointed out a number of spots where it's easy to use the wrong bolt or to attach smaller pieces in a logical way but then find out the last bolt is inaccessible. After doing this a while he just steps through it naturally. Desi says he just gets in the zone...

The Lancia 037 was a silhouette racer; while it was loosely based on the Lancia Montecarlo (also known as Scorpion in the US and Canadian markets) road car, they shared only the center section with all body panels and mechanical parts being significantly different. Steel subframes were used fore and aft of the production car center section, while most of the body panels were made from Kevlar.
The mid-engined layout of the Montecarlo was retained, but the engine was turned 90 degrees from a transverse position to a longitudinal position in order to decrease the vehicles polar moment and improve handling.
An independent double wishbone suspension was used on both the front and rear axles, with dual shock absorbers in the rear in order to cope with the stresses of high speed off road driving. The 037 is notable as it retained the rear-wheel drive layout that was nearly universal for rally cars of the pre-Group B period; nearly all subsequent successful rally cars used four-wheel drive, making the 037 the last of its kind.
Unlike its predecessor, the V6-powered Lancia Stratos, the first 037s had a 2.0 liter 4-cylinder supercharged engine. Based on the long stroke twin cam which powered earlier Fiat Abarth 131 rally cars, the four valve head was carried over from the 131 Abarth but the original two carburetors were replaced by a single large Weber carburetor in early models and later with fuel injection.
Lancia also chose a supercharger over a turbocharger to eliminate turbo lag and improve throttle response. Initially power was quoted at 265 hp (198 kW) but with the introduction of the Evolution 1 model power jumped to 300 with the help of water injection. The final Evolution 2 model produced 325 hp (242 kW) thanks to a displacement increase to 2,111 cc.

The top ring is designed so that the metal collar at the bottom of the bushing slides through it in the cup, while the two opposing protrusions push against the subframe. The tool must be perfectly centered - if it's not, it slips on one side and the ring bites through the subframe exterior coating - which is what happened to me. I re-centered the tool and it stayed in position this time.

removed all teh old oil an thick grease with a screwdriver an brake an parts cleaner !! .. then shotblasted it .. took me just over an hour
I was intending to remove the engine from the top, but after a day of removing rusty bolts and attempting to split the gearbox in 3 foot wide of space, I spent 15 minutes removing the 8 bolts and wheeled the whole frame out through the bottom.
To make the bolt drop all the way down and lodge itself in the chassis I had to push and pull on the subframe, raise the sagging differential a bit, and then hammer away on the knurled bolt head from inside the car; otherwise the bolt would just turn on its axis. I couldn't find out if the nut was supposed to be a single-use self-locking nut so I used some red Loctite and 120 foot-pound of torque. I found the number somewhere on the forum; it may not be accurate, but the Bentley does not say anything about the subframe, so there...
Notice the healthy gap between the support plate and the bushing. It will become smaller when the car is back on the ground.
