A little love to the undercarriage. Newly sealed oil pan (no dings) and a new oil pump and screen/filter installed. Since this motor was built over the time of 16 weeks and no rush all the seals were allowed to cure properly. All torque correct, etc. The dealer had to order new "go, no-go" gauges for the build as the ISF motor has clearances that are 1/2 the of their other motors (tight).

The very complex VVTi system, Hydraulic on one side and electric/solenoid on the other. Love the Chain driven timing, never needs replacement!

Nice large water jackets for efficient cooling. All new "stretch" hardware was used to replace single use type bolts.

The reassembly was done in the Lexus Service Manager's office to make sure the environment was clean and at "room temperature". The dealer Senior Master Technician did all the work by himself. It took a long time but was done right. He had a side business where he was designing and building his own motor from scratch. A three cylinder for an extreme high milage three wheeled vehicle. AND, no valley plate leak as it was removed and reinstalled for this work with better sealant than the factory.

The cylinders were each honed to break the varnish build up. One cylinder was fond to not be "true" or "square" it flared out as it went down toward the crank. The honing straightened this up. A set of various size rings were ordered and each piston was hand fitted with the correct size rings to fit it's individual cylinder for perfect compression.

New Springs are in. The heads were sent out to be rebuilt by a local race engine builder, Gromm Racing Heads. Valley Plate resealed/installed. No leaks!

New piston rings were ordered for the rebuild. Engine has oiler jets behind each piston to spray the backs to keep temperatures down and improve lubrication ala race motor design.

Water pump was leaking and replaced with updated part number with different gasket.

Thrust bearings at end of crank showing premature wear. New bearings used for the rebuild and hand fitted.

Heads clean, no varnish build up, no sludge. 5W-30 Mobil 1 changed at 5,000 mi intervals.

Lots of springs, more than 1/2 were found to be out of spec. Either short (squished) or our of round (oblong deformation). Likely culprit of the noise. Related to the Toyota wide recall of V8 valve springs do to a manufacturing robot of the springs being out of spec. New replacement springs came with same part number but different identifying marks (paint strips) on them.

They could have stored the parts a little better. The exhaust manifold developed the notorious separation/crack/leak about 20k miles after the rebuild. (replaced under warranty)
