Hey guys so I know I'm suppose to keep the rockers in order. What other important steps like these am I missing. I heard that we have to draw a line on the Harmonic balancer to the crank is that true? What else am I missing like important steps like these what about when i place in my new springs. And the steering rack, thanks all info helps!


This is how far I am

holy moly you really went to town on it! awesome stuff... sub'd

p.s. I would cover the engine ports to stop dirt from going in there while you work on it...

CammedC6520

Yeah I take them out while working on it, I use a garage bag and cover it. And yeah yesterday I took out most of it! Excited to start putting it all back together.

Nice! Check my build thread, i cover a lot of those minor details that aren't covered in some of the how to threads.

CammedC6520

Will do!


Still need some answers if any one has them. Also are lash caps those metal cup things on top of the intake side balance springs???

jayyyw

Yes. If you are keeping the titanium valves, you need to reuse those.

Tape the steering wheel down when you pull the rack off.

Springs need to be installed to a specific height/pressure as dictated by the supplier.

Assembly lube, loc-tite, wd-40, goof off are all your friends for this.

What about the harmonic balancer? Does it need to be aligned with the crank?

Holy sh*t man...you bought this car like a week ago.

MTBSully

I would say no. When i removed mine there was an orange paint mark for alignment I assume from the factory. They were not lined up from when the previous owner did his cam swap. Ran like that for 5000 miles with no issues. Because I was there I lined up the marks when I put it back on, but I do not think it is necessary.

CammedC6520

lol I told my self the same thing. But screw it had to fix the heads might as well get a cam for another 800$

Props dude... You guys who actually wrench on these cars have mad skillz.... I only wish that I had the huevos to do that...

Yes, that is very important when reusing the OE damper.

CammedC6520

Before this all I changed were exhaust. And body panels but this **** is easy it's just time consuming and a PITA some times. But I'm having fun while doing it. And saving me thousands of dollars and learning!

Its all just nuts and bolts.

CammedC6520

I got a question once I have the cam inside and the cover on etc and put the Harmonic balancer should I then. Installl the new lifters add the trays then put on the heads add the push rods and put on the rockers? Do I need to do anything special or can it all go in order like that. Can I put on all the rockers then go down on all them with 22lbs I also have the rockers in order when I took it off. Thanks!

spy2520

That pretty much sums it up. For the rockers you can either put them all on at 22ft lbs, rotate, check torque again.

Or set cylinder 1 to tdc, tighten exhaust rockers on 1, 2, 7, 8 and intake rockers on 1, 3, 4, 5. Rotate the crank, tighten the rest.

I've done both methods. Personal preference i guess.

Dan_the_C5_Man

You should take the small extra step to rotate the crank (bumping it with the starter is fine) to ensure you aren't trying to tighten the rocker bolts against open spring pressure with the lobe of the cam on its peak.. Just common sense.

CammedC6520

Ok thanks guys and should I put oil on the lifters and rub the cam with it when I install same with sprigs and rockers and the tray? Another other important steps I might miss?

CammedC6520

Oh and should I clean the pistons and the area where the head gasket sat if so what should I use and how thanks guys! Sorry for the questions

Michael_D

GM top end cleaner and rags. It's a friggin mess. Try to get the carbon off of them, and keep it from getting into the engine. A putty knife with rounded corners can help with this. No abbrasives. Make sure you run thread cleaning taps down the head bolt holes, and blow them out with air. NO WATER remaining in the holes or you will end up with a cracked block. Oil the lifters and the cam. Buy new lifter too. Trays should also be replaced. The block where the gasket rests needs to be clean of old material. Gasket remover works well for this.
