Couple Before shots for comparison. The After’s look way better! 🙂
We begin by tearing the engine down, looking for any obvious signs of damage. Inspecting all the components to make sure it all looks good. Then all the parts go into the hot tank for the initial clean to remove all the grime, gunk, and grease. Now we can really see what we are working on.

7M-GE VALVE JOB
Sometimes I miss the Valve Job progression. This is one of those times. By the time I got shots, the head was already done, ready to be put on the block. It looks good on the block as you will see. Here is what we did. Valve Job: Pressure test, Resurfaced to a nice flat surface to mate up with the block. Grind valves, Cut 3-angle valve seats, Lap valves, Install new exhaust guide inserts, install new valve stem seals, clean, paint, and assemble.
BLOCK WORK
Remanufacturing the block consists of Bore, Hone and Decking it, readying it for the rebuild. Cylinders are measured to determine current size, checked for ridges, scoring, gouges, and general condition. Once it’s bored, we hone cylinders leaving the proper crosshatch. Clean in hot tank to remove any metal debris. Deck the block surface. Last we put a coat of primer, then a few coats of paint.
TOYOTA 3.0 7MGE ASSEMBLY
New engine parts for the rebuild: Pistons, Rings, Bearings, Gaskets, Freeze plugs, Timing Set, and Oil pump. Block work is finished. Valve Job is finished. Connecting Rods, Crank and Cam reconditioned-reground and polished. We’ve got all the ingredients to start building the Short Block.

Ron Fronheiser
curious of the $$$ cost on the 7MGE build that you showed here?
Dan Kennedy
Yes but-
My ‘88 Supra non turbo engine is warped along the top of the cylinder block and “arched” about 8mm+ ! The head assembly etc. has been removed.
I have not tried to hand crank the engine to see if it will turn.
Is this block worth plaining and other millwork or should I look for
another MA-7 non turbo engine?
