I really need to know the estimated time for doing somthing like this.

Engine:
305 LG4 V8 / Carb'ed

If you can give me your personal estimates, or even the logged time of an install... I'd apprecaite it, I have to have this thing on the road by monday, otherwise I loose all my credits at school and could very well loose my job.... *** I HATE THIS!

Oh, and if the timing chain DOES go, will it cause any other damage?

And if it just Jumps Timing, then what can I do that may be a bit simpler to do than this?

Depends on your technical experience. I imagine you could have it done, in a max of 2 hrs, most likely less if you're more experienced like some guys on here.

Prolly take me 3 weeks.

Oh, your sig is way too long, you better change it, before the sig nazzis get you.

 

Last one I did took just about 2½ hours, tow-in to drive-out... but I had to stop and get a timing cover because like an idiot I didn't have one on hand...

 

Do you have to drop the oilpan, or can you loosen it enough to get the timing chain cover off?

 

You can loosen the front 3 or 4 bolts, that's enough to let it get back on without too much of a fight, if you grind a little off the ears of the thing that goes around the back of the oil pan seal.

 

Yeah do it like RB83L69 said and it will go together fine. If you have the time you can drop the starter and get to even more pan bolts and lower the pan even farther.

A couple of friends and I recently changed the chain on an 84 LG4. It took us most of a weekend. None of us had ever done it before; experience would make the job a lot faster. We spent a lot of time trying to figure out what was holding the timing chain cover on, and a fair bit of time getting all of the accessory brackets back on in the right order.

 

The only real atypical part of this Job is pulling the Balancer.

Other than that, its pretty much a lefty-loosey righty-tighty sorta thing.

And yeah, Your sig is probrably a little longer than it needs to be, but at least it dosent have the bling-bling images.

 

If the timing chain broke (or slipped a few times), you may have kissed a valve or two with the pistons since they're not in sync any more. Just have to hope that didn't happen..
A compression check afterwards will tell ya.

You'll need a damper puller AND installer.
Auto-zone can probably hook you up with those.

If it really did jump timing, the chain and gears will need replacing.

Might consider replacing the thermostat while you got the coolant drained.

Time estimate?
That's a tough one. 2-5 hrs depending on what goes wrong and how far away the auto parts store is.

 

i've done this a couple times already and both times had to loosen all the bolts on the oil pan. the second time i tried grinding the flange on the timing cover but i just could not get it on without lowering the pan. other then that make sure you align the dots correctly and use a puller/installer tool for the balancer. by the time i write this it's probably too late but just letting you know my experience. hope you got it together!

 

LOL.


I found taking off only 2 bolts on the pan worked fine...
