GM engine guys, I need your help!

Hey Glockman23c , did you get your engine repaired?

 

[nascarfantoo]

Years ago (30+) had a hydraulic lifter collapse after changing oil. Talk about a noise maker on a 4 cyl.

Good luck Glockman.

 

[GLOCKMAN23C]

No, I've got an engine to put in, but have a broken exhaust bolt, in the head, that I broke an "e-z out" off in. Does anyone know where I can get a bit hard enough to drill the *@$?;' ez out, out?

 

[giovani]

Get a center punch ,as in pointed and smack right on the broken easyout some times you can shatter them, have done this with broken taps too.

Drilling out and retapping a broken bolt is by far a better option for the future, not being a smarta$$ just 20 plus years of doing it 6 days a week.

couldn't say when I last had an easy out in my hand.

I knew better, I didn't have my tap set, and now I'm paying the price.

Good luck!

 

[GLOCKMAN23C]

Good luck!

Thanks!

I have made progress drilling the ez out, out. Slow, is the only way to describe it. I'm using a diamond cut carbide bit.

I'll try and make this short, I replaced the intake on my 1996 GMC Truck, now, I have what sounds like a piston rod slap, that was not there before. It is also hard to start, and rough when it finally does.

Here are the specs:
1996 GMC Sierra Extended Cab Long Bed
5.7L V-8
Automatic Trans.
4WD

I set the [STRIKE]timing[/STRIKE] distributor to the timing marks on the crank balancer. I know I had it set incorrectly the first time I put it in, and am pretty sure it is right now.

Did I FUBAR the engine?

Is there a possibility it could be a collapsed lifter?

 

[GLOCKMAN23C]

Beararms, it is most definitely not a collapsed lifter.

I finally got the "ez" out drilled out. I will never mess with one again. If anyone wants a full set (minus the one that broke). I'll be putting it up in classifieds later.

Tap extractor.. Not easy but well worth the money.

 

[GLOCKMAN23C]

Ok, I finally got the engine out. I took the heads off, and here is what I found.


Damage done to the piston


Another small piece of ferris metal of unknown origin

I knew something was on the piston. Looks savable. I have seen far worse be re-used.
