Gotta change the oil soon on the new car but I noticed the previous owner overfilled it pretty badly....will quite a bit of overfill have negative side effects? I assume there are some..such as? Excessive oil pressure, etc.? Pressure is right in the norm. on the gauge. Course it's also very dirty and thinned out a tad.

Also as a sidenote...gunning a car full-throttle in first gear and hitting 6500 rpms when the redline begins at 5800 and the tach only goes to 7000...yes, this is stupid, I am aware...accidentally did this..*** I need a rev limiter...but what parts are at risk doing this? Head gasket? Other stuff? Luckily the engine has been rebuilt...I think...it runs too good to have 147,000 on it like the rest of the car and tranny does, and it DOES have a cam and I suspect used to be a nitroused engine so someone's been in there before...

Thanks guys..

 

if it still runs, nothing mostl likely was broke..

i ran my 88 formula 350 way up into the redline and it ran fine after that..

 

Geez you people like to abuse your cars. I've only had mine up to a lil over 3000!

But who knows what kinda hell this car went thru before I got it.

 

If the engine is new, that's fine. If it has a lot of miles, that could cause excessive wear, especially if you've got air in your oil from it foaming as a result of being overfilled. Look for burning oil at idle in your future if you really fear that you messed up something. I'd doubt it, though.

Still running is only an indication that it still runs, not that you didn't cause a ton of premature wear. I can almost pinpoint a time like this with my old 305 that it began to burn a lot of oil. I'm not sure if it was the cause, maybe it was a coincidence. But the engine did have 130k on it, and by the sludge I found when I took it apart, the previous owner didn't care for it much(he worked at a honda dealer, too).

 

These guys pretty much have it right.

Other than increased wear, assuming nothing broke (which would be obvious), there probably isn't any damage done.

My bone stock L03 went right off the tach one time. I was travelling on a highway in North Dakota, and the throttle stuck at about 7/8 open. After hitting about 150 kilometers per hour with the cruise control set at 120kph( ), I pulled it out of gear, and the engine revved like a mother. It was plenty off of the tach (prolly 6,500) before I turned the key off.
I do remember it sounded pretty nice out of the Flows, even though I was filling my shorts at the time.
The same engine still runs fine, with nearly 245,000 kms.

 

I'd dump some of that overfilled oil, the crank will hit the oil and aerate it causing bubbeles to be sucked into the pickup and put through the engine, causeing allot of wear. also figure out why it is overfilled, dose it smell like gas, or have a milky apperance to it, you could be running rich and diluting the oil, or worse you could have a internal coolent leak and that could be diluting it. defanitly have that looked at.
for the overreving part, accelerated wear, and the valves hitting the pistons due to valve float are the only damage that could be sustaned(short of somthing really letting go, like a connecting rod or a piston pin- you'd know if that happend), as long as it still runs fine I woulden't worry, mine just peged aganst the rev limmiter about a week ago when the carpet got caught on the pedel, allitle scarey when the car is in nutral and bouncing from 6000-6500 RPM's (my rev limiter is set at 6000- it starts randomly cutting fuel and spark till 500rpm above the set limit than it cuts everything alltogeather

 

3000!!!! Damn grandma, open it up a bit.

 

Lol...well my oil has no milky texture to it and it doesn't smell like anything...looks a little thin but it's pretty old and dirty, so.... I'm changing it as soon as I get some cash...agh, so broke... Yeah, nothing happened at all after hitting those rpms..I was kinda shocked....my Camaro always sounded like it was gonna blow up once it got past say 5,000...it had a grumble to it.. This car flew right up there with no troubles or complaints at all...hell it SOUNDED like it could've gone right past 7,000...but talk about a beautiful sound that was..the Flowmasters, X pipe, headers, and that wee little 302 way up in the revs....

 

Bahahaha!

 

lol. Sorry I want my engine and car to last. Reving it up to redline or close, for some crazy reason just doesn't seem like a healthy thing to do. Especially on an engine that isn't new. Agree to pay for a new engine in case mine blows up and you'll see this grandma haul ***!

 

Do you know what 3,000 RPM will do in front of a 2.77 axle in OD? A little something like 105 or so....
