TOP END REFINISHING

Last bolt, w/ alt bracket + emission pipe... WTH is that hairy jam in that hole?

[Schrade]

I saw a couple of them &*%$ers tryin' to dodge the rag, and I know there's more of 'em hidin' in there...



so I introduced 'em to Mr. Shop-Vac. They didn't look happy gettin' bounced from that party either, goin' through the tube

[Schrade]

Sink (loosely) the last 2 bolts, at the Alt-to-IH bracket, make sure everybody is happy (note to self - don't forget to lock down the Alt bolt)

and how 'bout that custom snapped off IAC locking tang (inset; upper right); should be good for a few HP???

I don't know WHAT to do about that...

[Franke]

Schrade. Lookin' good so far. Cleaned up really nice. My IAC tang is gone too. Just curious. Are you going to test the fuel injectors before installation for leak down or sticking?

Absolutely static FP test ASAP. Just need to do it CORRECT...

Transplant surgery. I sure didn't know that rail / injector assemblies could NOT be inserted whole . When I tried it earlier, just one side, it almost went, except for #6 primary (secondary? like I said, I don't know much) (which was difficult also by itself, here).

Try to keep these guys outta' the dirt between the rail and the IH. As far as I'm concerned, they are STERILE...




clips in the oil drink



one home, 7 to go.

This one fit snug. I gave it a roll, to make sure the O-ring was seated happy, and it is.
But, each secondary INJ did not sit as snug as each primary ???



P side; 8 home.

I actually did sink the injectors before torque-ing the IH bolts. Said it before; I'll say it again - I don't know this mill like some others of you here... wish more of ya' would chime in here before I screw up.

I did 5 'circuits' , torque-ing the bolts; center outward (DO THEY NEED RE-TORQUE-ING, AFTER X MILES???) .

And my torque wrench - ratchet-type, isn't calibrated. I can 'feel' better with the smaller ratchet... WHAT IS TORQUE SPEC???

Anyway,



then set the clamp on the CC tube (in a different spot thAn before!!! )



Grub break I hate breakin' for grub when wrench hackin'.

Schrade, According to the LT5 service manual supplement the torque spec for the IH is 19 lb ft . Be sure to secure spark plug wire harness retainer with injector housing rear bolt on right and left sides. should be in your pics somewhere.
Coolant outlet pipes are 89 lb in.
Fuel rail to IH is 19 lb ft
Manual doesn't specify re-torque after installation so I would make sure you hit those torque numbers on the money with your torque wrench. At least 3 circuits around. There is no sequence in the manual as where to start but I do center out in a circle.

Note: these torque specs for the IH and fuel rail is different in the general engine section 6. That section indicates 20 lb ft instead of 19 lbft. Strange.

Hose end after wire wheel (NOT over rail!!! )

look ok Cliff ?

THanks for specs there Franke; too lazy to grease up the FSM pages ATM, with grease - grub grease!

Half a yard bird, snap beans and 'taters, down in 5 minutes!

I know that's just what ya' wanted to see...



Moly grease, THIN film, both sides of coolant man gasket
