Topic: Timing chain cover

[twistedtoy92]

   dude,  thats the point. metal guides DONT BREAK

Being a mechanic I can honestly state that ANYTHING CAN BREAK    ..... But Metal guides dont just SNAP, obviously there was a defect in the chain.

[79coyotefrg]

The autopsy continues. When I loosened one of the timing cover bolts I heard the chain tensioner snap. Apparently the tensioner bound up at some point. The resulting loose chain caught on the steel guide and broke a chunk off, the chunk followed the chain down and tore up the inside of the timing cover.

i'd love to see the "metal backed guide"  this guy used.

The one concer I had was if I remove the front diff would there be any chance of the front end collapsing to the ground?

[79coyotefrg]

no,  it will not go to the ground

How much effort does it take to turn the crank? I am asking because I left the head off the block and there is some surface in the engine. I tried to turn it by hand, but it is a no go.

[79coyotefrg]

it takes a good bit of effort to turn the engine but if  you have a 8 inch long wrench on the crank pulley bolt  you should be able to rotate the crank

[sparkynacho [OP]]

What if I broke the crank pulley bolt? Things are not going smooth with this engine.

I would use a remote bump starter switch, or put the pulley back on and try turning it by hand. As for the broken bolt in the crank, you can try to carefully weld a nut to the broken bolt in the crank unless its to deep. I have extracted many broken bolts like this in the past from different applications. The heat from the welder is usually enough to loosen the broken bolt. And since there is a nut welded to it, you can use a wrench to pull it out.

FYI, Sears sells remote starter switch's,you might have to get it online, or you can buy it off a tool truck like i did. just a thought.   

[79coyotefrg]

he needs to get the broken bolt out first

[HDcruiser]

Agreed. Its a to bad he doesnt live in  SoCal, i would have him bring it over to my house and do it for free just to help him out. Im sure the frustration it starting to set in.

[79coyotefrg]

or Arkansas, i'd do the same, i'm 99% sure someone put that crank bolt in with red loctite and it just needs a torch on it to free it up

[jimbo74]

so the bolt isnt broken then? you are jsut worried?

soak it for a couple days with pb-blaster


the bolt is pretty thick, its probably fine, just try a breaker bar on it....

[sparkynacho [OP]]

I did break the bolt and what is left is inside the crank. Does this mean, take the engine out or is there a way around this? I would like to say that I do appreciate the advise everyone has given me. I am looking for the easiest way to put my toy back on the road. Some would say that it would be easier to just sell it and buy something else, but you never know what you are getting next.

i keep mine because i know whats been fixed, a new truck i wouldn't... keep it

And i already said this but wrote it before i realized that, so im leaving it  

i have, when breaking a bolt close to flush with the crank, instead of welding a nut on i ground a flat head slot out. now that the head isn't on the bolt it "shouldn't" have any pressure. I know it will, probably from the red loc tite glen spoke of. Once i cut my slot i grabbed a 1/2 drive flat head socket. I don't know what its for or where i got it but it worked well. I think i have seen them at HF and sears. then just replaced.

Some surface in the engine? like surface rust?

[sparkynacho [OP]]

I did mean surface rust.

you might have more work than you want with that last post   .  At least i would think you need to hone your bores. that means taking the pistons out which means taking everything apart.

I do remember that the 22re was a slug with the automatic transmission. I am considering doing a 3RZ swap in order to gain some much needed HP. The only problem I see is that I have to put a lift on my 4Runner in order to make it work.
