LS3 Rocker Install Easiest Way DIY 

Yes, at 2:39 time in the video, he says 22 lbs ft. I am correcting my own comment, distracted or my $3 dollars ears to blame. Nice!

My 05 5.3 will low idle and the oil pressure drops and need to us some throttle until it quietens down, is the oil pump change a big job?

@@petermeinert720 First is the oil pickup to seal. I purchase a muscle car type oil pan and came with 2 bolts on flange. Use feeler gauges on oil pump for wear, minor inlet and outlet oil pump housing edge smoothing so no sharpe edges to turn. Pan had no internal dump if filter plugs, great. Otherwise stake it in place so it can can't open. Use a "Sac City Corvette Bar-Bell". I alway use 518 red jelly at front and rear oil passage covers just a thin film. Inspect cam bearings as too much leakage happens as copper shows, inspect all push-rods ball for wear, install captured needle bearing on rocker arms and replace oil pressure switch, as most do for aftermarket gages, use Permatex pipe sealant and prepare for 30 degree 1/8" NPT adaptor at oil pressure sender for clearance. Please note drivers valve tips!! Mine had wear but not passenger's side. My only conclusion was to buy a second drivers side rocker are cover, put 16mm box end of wrench on metal air tube and rotate backwards then "TEE" both together for fresh clean air in. Run a stupid catch can, add SS wool from Dollar Store in cans inlet and place where cold. Route dirty air from valley pan. Use intake vacuum for return PVC. I used NPT, 90 degrees fittings and 2 feet of pipe on bottom, stuffed with SS wool, and cotter pins to hold SS Wool in place. I used soldered 3/4" copper pipe and clamps. Clamps held with aluminum rivets heads only into holes I drilled and support and hammer tap in place. I drilled holes in bottom from 3/16" to 1/8" inch from rear to front for oil drain back. Dielectric grease new knock sensors at block, seal top and bottom seals with high temp red completely. DK. Good 2023!

no

Yes, he is putting the “rod” into the spark plug hole to see whether the piston is top dead center or not.

I heard the 5.3 was not an LS , but I haven't done much research on it,

@@petermeinert720 it's the most popular ls engine made

You are incorrect, the rear steamports are blocked off in trucks due to the engine being tilted, look up definitive ls guide on the web.

​​​​​@@shadowopsairman1583 lmfao this is not a ls3 period.

And technically the 5.3 6.0 are not ls the aluminum block engines that’s are designated ls1,2,3,4,6,7 are the only “ls” engine but they all share same architecture

That's what i'd like to know.

I was thinking the same. Looks like no response yet, eh?

@@ThePhotoForce probably more airflow, I think the factory square head port heads can only only go up to 600hp

@@alexeyscedillo8113 that's the odd part, the rectangular port stock ls3 heads flow much better than cathedral port so it seems that they did a downgrade unless they did some pretty serious porting and polishing on those. oh well, who knows. Great video none the less.

@@alexeyscedillo8113 maybes the ls3 is on a truck, hence why they used cathedral heads cause that what they had to work with. Paired up with a tbss manifold should hold up great and make similar power as the ls3 manifold even Richard Holdener tested it

Ok top dead center means you are on the compression-fire stroke, so that means both valves are closed and your lifters are on the base circle, not the lobe of the cam. Look up 4 strokes "5 events" of an internal combustion engine, 720° it occurs in. Suck, squeeze, bang, blow.

Check your lifters and pushrods again, also your lifter trays

Top dead center the pushrods are a bit higher than the rest. Even if everything is on your car, you should still be in dead center if you took it apart.

If you don’t like don’t watch

I like the background music

If you can’t understand that the procedure is the same and port means nothing than you need to get off mommies computer

@@TestDontguess mommies computer? What the fk are you 12 years old ?

@@TestDontguess you are the one who said ls3. Just say ls.

@@TestDontguess didn't you learn shapes last week in kindergarten? I see the problem.....YOU'RE CANADIAN !

You can use whatever heads you wish on your build 🤦‍♂️🤦‍♂️🤦‍♂️🤦‍♂️ can you even change a spark plug
