Check out this 4g63 rebuild

Got that on 3si.org.
I'd post it in tech, but there is more wrong with the assembly than right.
I got a good laugh out of it, hopefully others will as well.

I actually found it quite educational rather than funny. I think its a great video. I'm thinking about upgrading to aftermarket rods and doing a ring job this winter.

Thanks for the link.

So for someone like me who does not know what would be the proper way, can you tell me what was wrong with it? :)

[Onefast99gsx]

Yes, please tell us what the guy is messing up on.

I counted 5 mistakes just looking through it quickly. Not too bad overall though. Definitely quicker than I do it. It takes me two hours just to file the rings properly and put the pistons in.

I'll give ya one freebie. He's rebuilding a 7-bolt. :D

the stupid girdle or whatever its called!

-E

-Clicker wrenches on critical points, no no.
-No assembly lube in the cylinders, means a dry ring install, no no.
-It has a full main girdle, means its a 7 bolt, again a no no ;).
-I did not see any evidence of the following means of checking used:
-Mic'ing crank, plastigauge, rod stretch gauges, anything at all for measurements of clearances?!?
^ I am hoping they missed that part for video purposes.
-Beating the pistons in with the bottom of a wooden mallet is cute, especially when not holding the napa piston ring compressor, great way to f* up a ring.
-It would be nice if he used rubber/latex gloves when touching bearing material, fingerprints can create hot spots/marks/faster wear areas.
-I really hope the block was line honed and those are new style arp main bolts...
-Again on the crank install, it doesn't appear they the seat the bearings or the thrust bearing, you see they have a dial indicator on the end of the crank, so I am assuming they did this.
-He tightens the main girdle/cap down wrong. With the flywheel side of the crank at your belly (the position he is in) he is supose to do the center 2 first, starting at the 'top (towards the car)' of the motor. Thats 1, below it is 2, then the next one would be the next set of bolts to the left (next set away from him) and away from the car, then towards the car, THEN come back to you for 5 (towards the car) then below that is 6..Then finally 7 which is timing belt side, away from car, then 8, above it, then 9 is towards car..flywheel end, then 10.
He is using arp's, so they are to a torque spec, not a degree.
-That type of ring filer is very hard to get a "square" edge on. I've used them, they suck.
-I saw lube put on the rod bolts, but nothing on the main's ...maybe something they didn't video.
-head was torqued on in one stage it appears. Again, wrong. Also, no arp lube looked like it was applied to nut/washer.
-Cams were put in dry..ouch.
-that motor mount has a torque spec for a reason...
-Then just some small stuff, like I usually put the front case on before the water pump/mount. Not saying thats wrong, just 'different'.
-It didn't show him prep for the balance shaft elim (like plug oiling holes/spin bearing)..etc.
-a few dozen more things im to lazy to list.
I don't know, I don't have all the time today to list WHAT isn't shown, but it is a good video in this sence:
1) The music is cool.
2) It does show a general "how to", I just hope people don't take it as a verbadem example of how to build a motor.
3) The overall idea is very cool.

I posted it so a few of the engine builders could get a kick out of it. Great idea, and they are brave to do it on video in such conditions. (dirty garage, etc).
I won't even go into what we do differently, but for a garage build, the methods used aren't that bad I guess, all things consitered.
edit*
Oh, that was my first time through it, I just watched it again to somewhat list them in cronological order.

DAM!!!! Somebody has built a few motors in their day.. :)

1 or 2.
