Actually IT'S TIME TO TOOT YOUR HORN IN TRAFFIC!
You just made 100,000 miles!
I'd add change vacuum hoses & clean out EGR assembly.
I just did that to mine & it SURE HELPED!
SMOOTH idle.
I already changed my timing chain.

I need add a balancer snout sleeve in the Firebird, to fix balancer grove that allows oil to leak past seal.
Cost is only $4 for part!
I wish I knew earlier when I did swap!

What's funny is that today, I was paying so much attention to my odometer that I MISSED my turn on Hollywood Way to get to the 5 FWY. OH WELL it was a very cool sight to see. Any other suggestions guys? I'll definitely go honking my horn tomorrow.

I've watched my S-10 Blazer do it twice, so far.
I have 211,500 miles (powered by original 2.8) so far.
The 3.4 engine should help make it easily 400,000
I have
changed engine
rebuilt this tranny
swapping in lower milage 3:42 rear from a late 80's/early 90's S-10 truck & it looks brand new.
My suspension is poly bushings.
Original rubber frame mount doughnuts show zero aging.
Since my Blazer is in SoCal, I see zero rust, so far.
What not 400,000? Or more?
I really do love this Chevy truck, my Firebird is great, also.
Better "love" your rides if you want to claim the high milage prize

If you want to do it right:

Coyles Double roller timming chain
Take the upper plenum off and clean it
New Fuel Filter
New Converter
CRANE 2030 cam and vlave springs..

A chain's a great idea; although I admit that I waited until 180,000 miles to do mine. But if you've kept up with your preventative maintenance, there's really no special thing you should do at 100,000 miles.

The cluster in my '86 is only six digits... I could try selling my car with 40,000 or 140,000 miles, instead of the actual 240,000 that's on it. But, the cluster I pulled from the '86 2.8 with the full gauge package had a 7-digit odometer. Weird, eh?

You've taken rides in my car.
That's what a new timing chain does for your ride.
It can solve SO MANY PROBLEMS.
We're gonna have to get ya a 3.4 block soon!!
You'll be needing it!

I'll let you know it a few weeks what a new chain will do, granted mine only lasted 60,000. My first one was changed before 100,000. Now I'm at 140,000 and having big issues with the 2nd one. Wish I knew where it came form. Had a mechanic friend do the work and I bet he put in cheap crap. No cheap crap this time.

When I hit 100,000 it was soo cool! I was passing my towns local Pontiac Dealer. There was a new 4th gen red Firehawk parked out front. They had never had one in at that dealer before. As I passed it, the odometer rolled to 100,000. Pretty wild!

Rebuild your distributor if you havn't yet. This helped my car soo much!

I bought my car with 170,000 miles on it I've got a '95 Ford F-150 (Straight-6, FI) that just hit 220,000 last week. Guess that's what happens when you faithfully change the oil in a vehicle

Yea, so umm, there's this guy who lives around here I guess, and he was on the news because his Volvo hit 1,000,000 miles, and they asked what he was gonna do with it, and he said keep it. He said all he did was change the oil and give it a tuneup whenever it needed *shrugs* (Yes, this was on the news, my state can be pretty boring at times )

IN the news,
PLEASE
They did AN ENTIRE AD CAMPAIGN ON THIS CAR
It's a P1800 Volvo Sports Car, I think a 1966 model.
Nice car, too!
He has had engine/tranny/front-rear axle work done during those million miles.
His car has survived "all that" and the body & chassis have rolled 1,000,000 miles.
Yes, it still is a VERY big deal.
I believe Volvo purchased it & gave him a newer ride?
This ad/story was during the first gas crisis period 73 - 75. Volvos made their ad campaign of "Economy, Safety Longevity" reputation on this "one car".
The "Boring Safe Box" Ad campaign worked, too.

CT?
Boring?
Hell I wish I was Martha Stewarts neighbors.
Who needs the news, go to the fence & be told the "Financial" Gossip!
I grew up in Westport in early 60/70's

Westport's a nice area, one of the nicest in the state, knew someone who lived there. I live more in the New London area though ... and just because people live here doesn't mean it's exciting. I'm nowhere near the Greenwich border anyhow I know what you mean though, but having well-known people live here doesn't mean all that much excitement for me.

And no, it was a newer car. About 6 months ago this happened I believe, I'll try to find out more about it sometime.

Some of you guys really drive your car's some distance. I got my car with aroung 80,000 miles on it and it has taken me 5 years to get the odometer to roll over to 100,000 back in June. Now that my engine has 100k, it's time for me to think about a rebuild even though my engine is running the best it has ever have and I have not had any mechanical problems, only electrical.

1,000,000 miles

Wasn't it Al Bundy (married with children) who rolled over 1,000,000 miles on his car? I remember that the Dodge dealer was going to give him a new Viper for his car...only if they could film the odometer roll over to the 1,000,000 mark. All was fine until Peg (I think!) took the car out and brought it home with 1,000,001 miles on it.

Anyway maybe if we can roll 1,000,000 miles over on our car maybe GM will do something like that. Yeah right!

175,000 on mine with about 35,000 on engine. Besides a rough idle all is well!

Later guys.....

Actually what happened in that Al Bundy show is he fell asleep in his car at 999,999.9 miles and then he hit the shifter into Neutral and it rolled out of his garage. AHHA :sillylol:

Still need to borrow my girl's compression gauge to check which cyl is burning oil...

Hey Karl, up for Flame's on Friday night?

You would think the Chevy dealer would try to sell you on extra service. However, when I asked them about changing the timing chain they didn't recommend it. The service guy said is it making any noise? I said no, he was like don't change it unless it's making noise or broken. All the service people said this, it's not plastic or a belt like some imports so it's made to last long. I don't know if you guys noticed some big difference in the timing chain change but why spend the money if it's not broken. The only thing I have heard is if it's loose and slapping the block or front cover it can slowly break a hole into the cover causing coolant to leak into the oil.

Over time a timing chain will "stretch". Causing your timing to be altered. It makes it difficult to set your timing properly.

If it goes unchanged and it breaks....it could be disasterous. You could bend push rods,bend the valves even bust a piston.

9 out of 10 times when a chain "slaps" the block it will be on the lower driver side(your right side when looking at the chain) just after it comes off of the crank gear. If it does create a hole in the cover it will leak oil. And if somehow it (the chain) finds the water pump or a coolent passage will it leak coolent....but the odds are very slight of a coolent leak.
And a chain that is slapping has a greater chance of it slipping a tooth on the gears and ruining your engine.

I know you all know this already but I just wanted to put my .02 in.
A chain could slip a tooth well before it starts slapping the block.

With a chain change you will feel a difference..especialy if the old chain has stretched abit.

ANYTIME YOU DO A NECESARY TIMING CHAIN CHANGE,
You'd swear you just rebuilt the engine.
Compliment it by a fresh distributor rebuild,
beefed up spark....
WOW the difference is sensational.
NEVER WAIT FOR IT TO MAKE NOISE!

I did.
In my 1974 Corvette example with 130,000 original non-reuilt miles,
I found plastic teeth in the oil pump screen (GM used Nylon teeth on aluminum for "silence" back then. Maybe now, too?).


The 60* stuff?????
Simple, IF YA PLAN ON KEEPING THE CAR,
Close to 75,000+ miles, plan on doing it.
It is necessary.
Make noise? Waiting for noise is a dangerous situation, too!!
Only if you plan on keeping a car, should you do this chain change effort.
It's alot.
SO WORTH IT!!
ALSO GET A BALANCER SNOUT SLEEVE (it's only $4!).
Prevent any future leaks from your repair work.

From one having done four timing chain jobs on my higher milage fleet of aged, classic rides.

Although... if the balancer snout is fine, with no grooves or scratches, you don't need the sleeve. From spinning in the front cover seal for so long, the front seal can actually groove up the part of the balancer that slides into the front seal... and if there's grooves in it, you'll get a leak. Make sure to coat the seal with engine assembly lube before putting the balancer back on the crank.

It's cheap insurance even IF the balancer looks good.
It is an item about 10 years old now & it'll develope a leak after you do the job.

Spending $4 to prevent a future oil leak is cheap insurance.

I have to pull apart my 85 Firebird swap, as the balancer snout that was/looked good, now is leaking, slightly.
Plus I will be replacing the tensioner, as I neglected to during my 2.8->3.4 swap boogie.
Sucks.
Ya learn!
Balancer sleeve is cheap insurance at only $4!
