I stuff paper towel first just in case the duct tape gets moved.

Actually I use that Blue Tape painters use to mask off windows and stuff......it comes off clean.

Are you going to remove those cam covers

I should just shut up and watch

You got a helper...I can tell....someone else is taking those photos

Nope - no helper here Cliff - got one of the cams on a tripod http://www.zr1.net/forum/showpost.ph...2&postcount=95

But do feel free to do a road trip...

And breaking new ground. He has inspired me to attempt changing my own oil.

What I do for hoses that refuse removal is take my special tool (single edge razer blade) and cut hose length wise over the connector and then using a flat screw driver lift the cut edges (same on coolant hoses). Since I am installing new hoses anyway

Get a couple of these also from Jerry.........Grommet PCV Valve

Do NOT jimmy the surface of the Injector Housing......You could just take a single edge razer blade and cut off flush and then pull it out from the center.....

And breaking new ground

That scares me. I'm countin' on lotsa' help re-assembly here; LT1 was cake compared to this - did the same thing on CF before gettin' banned (for something else).

I slow down, bolts back in empty holes, post up, write stuff out as you go, helps to remember sequences...

IH cleanup begins (FIRST SIDE - might be ready for BG in the spring, WITH the Z, instead of my little Nissan sewing machine ) .

Oil the bolts, run 'em in and out a few times, clean threads with a toothbrush as you go



Label bolts config



ready for a bath

I left my grommet in and just undid the hose clamp and pulled the tube out. BTW, I have had the lid off my LT5 3 or 4 times and it only takes about 3-4 months for it to become filthy again. The C4 vette sucks up more garbage up its nose than a coke addict. Nature of the beast I guess. Good thing you are taking pics because that's the only way the clean will last.

Schrade, that grommet(s) may have been installed previously with some RTV and could be why it doesn't budge. Some folks do that to assure no leaks but it makes it a little tougher to remove too.

Doesn't most of the 'inside buildup / carbon', come from hammer down?

Just road dirt and dust-gets all in the valley of the engine in no time. Been there done that I washed my parts in the dishwasher to help clean out the metal shavings after porting.

Now THAT looks clean. Can I mail' ya' mine?

A little oil on the finger to lube them before installing injectors will make the installation easier & protect the O-rings from damage. FWIW, the original O-rings are 20+ years old and we now have ethanol in gasoline. You might give some thought about replacing the fuel system O-rings while you are at this juncture.

OK - going back re-reading stuff...
Damn if I didn't forget about the primary O's in the IH. Probably blew them out at the car wash (afraid to look now)...

And note to self (thanks again on this one)

I suggest you tighten the bolts (13ea, 8mm hex) first and clean all around it first so none of the gunk & grit around it falls in when the Cover is removed. Once it's off, virtually a straight shot down into the crank case.

It's no big step to go ahead & remove the injector housings while you are this deep. The bolts typically get loose over time and the gaskets may be in sad shape. A lot easier to access the Primary Fuel Injector Lower Seals with the housings on the bench.

Usually DO do cleaning before & after breakdown for this reason - another good tip there
