Upon close inspection of the pistons the 2 that were down on compression had little cracks. Turns out they were more then just cracks on one of them, the rings were holding chunks of piston from the cylinder wall.
It wasnt catastrophic failure more of a fizzle, First let’s run through the photos.
Bmws,”faded kids toy plastic” yellow.
Wonder how long they’ve been using these stickers in regards to the political climate.
Unused Harbor Freight 1 ton engine stand for $60. Both 1uz’s aught to be rebuilt so this is a good first step.
Post all the projects, racecars, and your cars.
Its not looking good, all cylinders are between 80-50psi with one at 25. For reference using the same test equipment, the old motor was at 140-150 with 2 cylinders sitting at 75 and 100 respectively.
Motors pulled, tomorrow will be spent organizing, maybe tear into the old motor to see what happened, and making a list of things I need to buy.
$500 engine showed up, 1991 ls400 1uz with 180,000 miles (ls400s have a front sump rather then the sc400's rear sump, different drive, and a different oil filter pickup)
5 alternators, 3 from a previous project with worn shafts, 1 of which is mostly disassembled(hiding in the back), 2 brand new ones that are getting upgraded shaft seals along with 360° thrust bearings.
Standard 1993 Lexus sc400 specs: 1uzfe 4.0L v8, a 4 speed auto a340e is the only transmission until. +97, 250hp, 260ftlb torque. Excessive detail after the jump.
Thats all vaguely burned oil at idle, now picture a thick smoke screen reminicent of a forest fire and you have 3000rpm. The new turbos did the exact thing I bought them to fix.
Photos my brother sends me, figured y’all can appreciate these.
