Problems after 200,000 Miles
 

I've had a few guys ask, so i'll make a thread on it. I'm in Kms, but I convert it for this.

-ECU died after about 6 months, warranty no biggy other then the down time.

-CSC, went through the original one at about 135,000 miles. (since then I've had to do the CSC 2 more times, the first time it was done I changed to a Stillen flywheel and ACT clutch, it was too much pressure for the OE CSC so I put the OE parts in and it's been good. The dealer even covered them this time, had the master done each time as well.)

-SL went about 150,000 miles, before the recall, got reimbursed after the recall and another one put in, just so they could say it was done and I had the newest version.

-Front hubs, cant remember when for sure, but about 150,000 also.

-Fuel sending unit had to be changed a couple times also, both under warranty, not reading full.

-Fuel Prefilter dirty causing loss of RPM at about 175,000 miles, I pulled the pump unit out and cleaned it, been good since.

-Paint wise, I have a couple paint bubbles starting, as I do drive the car all year round in Canada. As well the usual stone chips, which I try and fill as soon as I notice them.

Oil changes with Redline are every 4500miles, (i'm down about a quart each change) full fluid change every 60k with Redline oils also. Plugs and drive belt (accessory belt) if you prefer done every 75k.

Try to run only Shell premium fuel also.

If you have any questions let me know, if I can think of any thing else I will add it.

Thanks and keep driving!

200,000 miles?

Yes miles, I rolled 324,000kms the other day, lol

Nice man. That's a whole lot of driving

You should go RB26 after your engine dies man, I totally would

Love it man! That's great that only those few minor issues have come up after all that distance, and in the Canadian winters too! Did you have the undercoating done when you bought it? Any rust anywhere at all?

If this was a ford forum with the same title thread, I'd be scrolling down on the OP for the next 3 hours lol

Very nice. Keep it running. Love seeing cars go as far as it can.

Both buddies that want it have build LS7's. For want i need my DD to be i have to stay basic, no engine swaps. Besides i have a toy already.

No undercoating, just 3m on the front. Just the paint bubbles mentioned. And of course surface rust under the car.

What's the toy? :ugh2:

I'm assuming the '90 ST is done right up.

Edit: Check his photo albums ;)

Did you swap out any wheel bearings/bushings/suspension components?

See first post, front hubs at 150,000.

Yep as mentioned below, I have a 90 GMC short box with a built 454 with dual TBI injection.

How strong does the motor feel?

you use shell premium hmm...

i've been running petro ultra 94. maybe i should go back to shell lol V-POWER FOR MY V-TECH ENGINE!!!

Feels good, still pulls hard. No problems there.

It would be interesting to see what a compression test yields.

Love it! Nice work :driving:

I'm impressed the front hubs are the only real suspension work you've had to do :tup:

I'll chip in $5 to see it done

That's a really random repair though.

Exactly. I would have at least expected the shocks to have been replaced once or twice in that mileage.

Even more so if you could see the roads here in Alberta. Calgary isn't AS bad as Edmonton, but it's no picnic. I keep wanting to mount a GoPro to the front bumper low, pointing just at the road so people can see what it's like here.

You'd have people in Afghanistan commenting on the video like 'DAMN! You guys have SH!TTY roads there!'

When i change the plugs I'll do a compression test.

Im almost all hwy, not really any off road. Lol

Thank you for the great write up! Lets us know what to expect!

bit off topic but has anyone seen a 100k+ FI'd Z?

maybe 90st has a super block or something but it appears that this engine block is built damn well!

I need to follow up with phunk as we were both close but I know he put his car in storage & tear down mode for higher HP.
I just crossed 87k and had my supercharger put on my car at 19k miles, so coming up on 70k miles of boost on the engine.

Thank you for sharing. It's good to hear that the car is so reliable considering the mileage.

Just wondering if the oil consumption increased at higher mileage or it is about the same through out the 200k miles?

How about the transmission? Did the shifting get worse?

Somethings wrong with your 09, 90ST.

Mine only reads 16k miles... :ugh:

Great info 90ST! Sounds like you have a very reliable car :tup:

OK. I'm more comfortable now. I'm close to hitting 80k. Guess mine's just broken in. Thankfully the only cars that I like that could replace the Z are too expensive for me, so I'll keep it.
Thanks for the post 90. It really does boost the confidence level.

Thanks for the post! Have you recently done an oil analysis?

Thank you for you post, good to see the car overall remained pretty reliable. Most of those things are expected wear and tear items. I would also be interested in an oil analysis.

its gone to about a quart, nothing really in the beginning, but after 200k im ok where it is. Shifting has been the same but it manual.

never have, not sure we have a place around here...and im not really concerned, i do all my own oil changes and the oil looks good (not metalic) just dark no burnt smell either.

Might be your tire size, or maybe your 1.5 psi low in a tire or two. Lol

There is only one place: Blackstone. And you just have to request a free sample kit. They provide you everything you need to send it back to them (except maybe postage? I can't remember its been so long since I last did one). They charge $25 per sample analysis.

I wonder about shipping over the border...

It's not an issue. $10 roughly Canada Post

Best thread this year.

Too early to judge... What if he creates another thread with 300,000 miles update :TUP:

True story.
