Replace 5.3 l59 with this....

[RobsFreeland]

I have to add, what was a cam, cold air, exhaust turned out to be more than I thought. But first, scenario and upgrades, waiting for new timing gears chain and trunnions

 

[RobsFreeland]

Okey donkey. Pulled other head. Started to clean em up. Called local parts store machine shop and going to have them clean the heads, valley cover and rocker covers. Found a piece of gasket material lodged next to rocker arm, looked like I dodge a bullet. Day off. Yeah!!

 

[Mudsport96]

Sounds like you are moving right along. Cant wait for a running video clip

 

[RobsFreeland]

Just a couple of shots. I can still see crosshatch in cylinder. Have just a little bit of cleanup ahead. Just cleaning tomorrow. Maybe pull cam ,lifters timing chain. Dunno

 

[RobsFreeland]

I can’t wait for the running clip either.

 

[RobsFreeland]

Spent the day cleaning the surface of the block for heads. Took off timing cover. Waiting for parts. Think I’ll pull oil pump and timing gears, sprockets. Any tips to keep cam and crank from turning when yanking sprockets?
Also is there a screen under oil pressure sensor and where is it?

 

[RobsFreeland]

Well I think the screen under the pressure sensor didn’t start till 2007. That’s what I found. Can somebody concur?

 

[Mudsport96]

As far as I know, the screen didnt start till the displacement on demand started so 07-08ish?

 

[RobsFreeland]

Cool, great I don’t have to worry about it.

Dropped front axle, and got the pan off. Looks good, no sludge, screen clean. Dropped-pickup tube to replace o-ring.
Yanked lifters, pulled oil pump to get to timing chain for replacement. I think I saw 5/8 of play in chain is to much and replace. Almost to my goal of swapin cam out, for a nice one.
Then oil pump back on ....

Pick up heads tomorrow, had em cleaned. Bottom of the apex and now the new stuff starts going in.

Old o-ring

 

[RobsFreeland]

New o-ring

Spent the day removing timing gear on crank. I have 2 pullers one to small and one 2 big. Went to parts store borrowed puller. Too big. Bought smaller puller but bigger than my small one. Scavenged parts off each other to make one. Fits but not enough clearance to set screw to push against. Went to parts store bought flat head 5/16 or bugle head screw. Fit flush with crank shaft where the balancer bolt goes. Pulled gear off while trying to keep the 1 cylinder tdc. Got the new gear on. Geez what a day. Tomorrow put crank back to tdc and yank/ install cam.

 

[RobsFreeland]

All jazzed to put cam in and start the rebuild. NNNNNNah.
Put crank back to tdc or number one cylinder. Pulled cam plate and cam. Worn where it rides on rollers but not bad for 200000. Like I can really tell. I’m a new guy, re- living my glory days.
Went to grab cam looked at cam card, didn’t look right. Looked up specs and order sheet , #@#$&& wrong cam. Got with supplier who slapped me and said don’t do that again, reordered the RIGHT parts. Thanks supplier. Should be here moment into. Lesson learned, check and double check.

 

[RobsFreeland]

Yeh

Ls 6 springs, new guides/ seals. Installed on 5.3 ls flex. Waiting for cam and trunnion kit. Noticed on springs they have white stripe painted on have no idea what that is for. I’ll have plenty to do when cam shows.

You've been busy. Sounds like you've got a good handle on things tho.

Ask PNW VietVet about orienting the valve springs.

 

[RobsFreeland]

Iamdub was trying to pull a fast one. He said to orient springs north to intake manifold. Geez he was kidding just marks to ident .

 

[RobsFreeland]

Finally got the cam delivered. Put new cam in, new lock plate , new main cam gear and chain. Old chain had at least 5/8 play, this one pretty tight. Took me a few try’s to line it up but finally got it. Put in new oil pump with new oil seal on pickup tube.
Slid on my belly like a reptile and got the pan back on, all new stuff torqued.
Tomorrow put front axle back up, and move on to timing cover, then I can start topside. There is a light, faint but it is there.
