And furthermore..
So....I finally have a clean block,...it’s tapped for the new galley plugs, I can finally start putting the thing together. First I mask the thing off, and give it a fresh coat Of Gila Monster Copper. After that dried, I install the oil squirters that help keep the cast pistons cool, and lay my new coated “ race“ bearings in the main saddles. I open the box that the main studs are in, and my eye gets drawn to the big, red “ATTENTION“ warning written on the instructions. It warns me that main studs could potentially distort the main journal, and that I should have had the main journal line honed just to make sure that there were no issues with the fasteners clamping force on the main cap.
Fcking great...Now I gotta worry about this?
It is what it is. I figure I’ll torque the crank and see if the force required to spin the crank changes as I torque it. I start installing the studs. There is only 10 studs. I need 14. I look at the box, this is a stud kit for a freakin 4 banger...and I don’t have a clue where I got this kit from, or whether It was ordered wrong by me, or incorrectly picked shipped by the vendor.
I say screw it. I’ll just go downtown to the engine parts warehouse, and buy a set of TTY main cap bolts for the engine, and eliminate the worry about main bore distortion.
I call em up. They don’t have them.
I get online,..nobody out there is selling them.
When you watch the YouTube goobers assembling 2jzs, they are using TTY bolts on the main caps. Nonetheless,...nobody sells them.
* And these engines are so freakin overdone...how can this be?
All I can do if I want to go forward is to use the existing TTY main cap bolts for today, just to hold the crank in place. I thread those dudes in but don’t tighten them, I intend to replace them.
I check the rings,...they are in spec. A little loose, but within spec.
I install all six piston/rods into their respective holes..I bought a taper bore ring compressor specifically for a 86 mm std bore. The pistons slide in flawlessly.
But,..things take a decided WTF, when I spin the engine over and bring #1piston up to TDC.
it’s supposed to be above deck, but the pistons are down in the holes a tremendous amount.
They are at least .025-.030” in the hole. The stock spec only has the piston down .010” How in the hell is this piston down so low???
When the guy resized the rods, did he shorten the rod so much that these freakin things are now too short? And now I’m gonna have to take all of this sht back apart, and have the block decked another .025-.030”?
Naaahhh....I just had to remember that I only hand tightened the main cap bolts..the above pic shows the piston .005 out of the hole.....exactly like I was expecting.
