I thought my engine blew today

[ninjabortion]

Driving to lunch today the car had just warmed up and i head a WHAM then tap tap tap tap really slight because i killed the engine and coasted into a lot when i heard it. I thought the fan belt broke at first, but it was fine so i started it up and heard a metal on metal sound almost, and thought the engine was blown. Turns out the bolt i had plugged the egr port on the exhaust manifold had worked its way loose, and then shot out in the last thread or so.

what i found:

how it is supposed to look:

Walked back to where i heard it about a half block up the road and it was still there, had to play frogger to get it back:

Looks in decent shape:

Good as new

Loc-tite?

Loc-tite?

 

won't exhaust temps burn it right off?

 

and i have since found out the vacuum advance is in the wrong spot on my dizzy while researching issues, will fix that soon enough...

I pulled my emission tube off my exhaust manifold using a cut off wheel right at the manifold. Then i welded them shut. I don't have to deal with that shit anymore :D

This is the way i do every one of mine^^^^^

 

But since you already pulled them out ....go to hardware and get pipe plug ( with pipe thread ) the right size because that`s what the threads are and they will hold better..

Damn straight!

 

Metric pipe thread.

 

 

Vacuum advance never goes to intake vacuum. Take that short length of hose off the hard line above the rad hose clamp and connect the dizzy vac advance to it. Put the short hose on the other end of the hard line and plug into the rearmost of the two carb ports. The hard line behind the plug wire bundle is for the EGR so ignore it.

 

 

Now that you have it connected to ported vacuum you may need to reset your timing at idle. The dizzy looks like it's turned around wierd.

I ground them down more after this photo.

You get mad at something Izzo, the thermostat cover has taken some abuse here, really you should just yell F**K, and move on. :lol: My dizzy is in this position in this photo on all my L20b engines, isn't it the stock position?

[izzo]

:rofl: no

 

I dont abuse cars and beat on them, i do say F a lot if something goes wrong. I think that wire holder got bent when the engine caught air in my truck :blink: And good ? I shut it off, pulled the cap to get some room in there and thats where it was sitting.

yeah it is almost in the dead center of the adjustment slot available, but i will def recheck the timing after i mess with the vacuum ports. i'm getting pretty good at it haha
