Assembling an Engine… any tips?

[Jackson1320]

i'm sure you will not listen but you should get some cerakote v-136 for the top a bottom of the pistons and c-110 for the skirts. should look like this. you can apply the coatings at home. about $90 total

I don't think I'd want some amateur to remove and replace rings on a good running engine that I built. Too easy to scratch the piston or break a ring. If you really are green you could install it upside down.

Since you took it apart I'd clean the bores and hope for the best.

there is a lot that is going to go wrong with this build. all we can do is clean everything 3,4,5 time and pray

do you have a ring compressor for the bore not a autozone compressor?

Assembling my gen3 coyote shortblock.

Any tips on cleaning the engine and best practices when re-assembling? The motor was a used motor I bought from another user.

I’m going to leave the rings as the previous owner gapped them, but I am going to replace all the bearings.

Also thoughts on the cylinder walls? Is the spray in liner okay, and can it be damaged easily?

Hard to tell from this pic, but how deep is the ridge?

 

[Jackson1320]

you should us the first one maybe the second but as a beginner not the third

shouldn't be any. the coating very hard. so under 30k miles there should be zero ridge

Looks like a ridge to me in the pic.

Possibly a carbon ridge.
It’s impossible that there is “ZERO” ridge. That would equal zero wear and that’s impossible. The question becomes at what measured decimal place to the right of the dot (0.0000)
This ain’t Briggs & Stratton shit here.

Now back to the OP reusing the factory installed rings with 26k of run in.
What is the OEM installed ring gap orientation on all 3 rings ? It’s important that those locations are correct at assembly.

It’s important that those locations are correct at assembly.

Nah, they spin in the grooves. Just don't line them up. Top and second ring 180 apart. Oil rings 180 apart and 90 degrees from the compression rings.

if the cylinders are harder than the rings and oil got to them properly they can show no ridge

Like a ring compressor when putting the piston in?

I didn't know that it mattered if I use a cheap one or not.

Didn't have a change to check today but will check tomorrow. engineermike said he couldn't feel anything.

wherever you assemble is should be hospital clean.
what bearings R U using

Does my garage count as hospital clean lmao. Don't have anywhere else to do it, but if you have tips on how to make sure the engine stays clean I would like to hear it.
