how do u know if the rings are seated

[gtsfirefighter]

I changed my oil after the first 100 miles and it looked like it just came out of the bottle clean. I've since driven another couple hundred on new oil and it is still very clean. I'm not driving it hard nor am I real easy. I am new to boost so my foot is staying in it quite a bit.

Many years ago I owned an 83 Cutlass with a 307 V8. I had a short block rebuild done on it and after I put the motor back in and drove for about 500 miles, the oil was as black as coal. It took about 2000 miles to seat those rings good.

The only way to really know how well the rings are seated or not is to do a compression test. But on the break in ... i was pretty easy on it for the first few miles. I changed the oil alot! The first change was right after it warmed up, 20, 100, 500, and at 1500miles i switched to synth oil. I might have changed the oil too often since it was very clean every time but I am really cautious about oil related stuff since I caused myself 4 rodknocks since 2002 1st time I run out of oil, 2nd ran out of oil, 3rd time i bought a jdm and after a few months it develop a slight knock, and 4th time i rebuilt the JDM motor and did not do a good job cleaning the block after i honed it and on top of that i did not change the oil enough during the break in. I checked the oil somewhere around 500 miles and the damn oil was like glitter! Shortly after i started to hear someone knocking under my hood......

I was between 18-21 and all of this was on my red NA and i have learned the hard away about oil but anyways after the 100 mile mark during my last engine build which was also my first turbo build i drove it pretty damn after 100 miles hard but at stock boost. Now its 3 years later on the stock head gasket and 14psi and 50,000+ miles later (I drive 127miles a day!!!)

Im going to get a compresion test done in a few weeks and then off to the dyno

I'm a firm believer in the metod of driving the car easy on first startup until the motor oil is warmed up to operating temps, then do a WOT pull in 4th (away from any busy roads, of course) racing the motor up to about 5500 RPM, then letting off and having the gears drag the car back down, pulling the piston rings out far the entire time, helping them seat, and downshifting to keep the revs high as I get back down to about 15 MPH, then start the entire process over again and do this about 5 times. I then go home, change the oil and oil filter, and then drive the car easy after that, but fluctuating the revs to keep the car out of any set RPM for an extended period of time, with another oil change at 500 miles, and a switch to synthetic at 1,500 miles. Then drive it like you stole it, when you feel like doing so of course .

^Dont worry I do the same thing. I change my oil frequently on rebuilt engines. Its just a safe habbit. I usually do it after the first drive, then at 100, 500, 1000, then 2000 and repeat every 1000miles if its a forced induction engine if its NA I do it every 2-3000miles.

 

[bountykilla0118]

ummm most modern oils are changed too often .... synth last over 5000miles on forced induction and even more on NA motors.

I would say that depends on the application. I personally wouldnt trust any oil even rp for 5000miles in my boosted cars especially with aftermarket turbo setups and etc etc. On my evo I dont allow it to go over 1500miles at most and I even use rp.

(i sure am agreeing with you alot lately...not that i didnt before )

great minds think alike hehe

You sir are dumping perfectly good, expensive oil (after an initial break-in, of course). Not sure why you do, but I suspect it's the result of one or more of the many oil myths out there. This oil change "technique" is a total waste of time/money...it serves absolutely no useful purpose on a street car. You might want to read the info in the lube section

Bounty is correct...dino oil will go 4-5000 miles, a PAO or ester based synthetic will go 8,000 easy. Assuming you use a good filter. And this is on a turbo engine.

1500 mile oil changes and why are changing the oil so often? Is there some type of information backing up your actions or is this one of those “gut feelings” about something without any factual information to confirm this way of thinking.

Have you actually gotten your oil tested by blackstone labrotories or any of the other oil analysis labs out there to tell you that?

 

[buldozr]

its the classic dirt tracker way of thinking, run very rich, have a little blow by, excess gas in oil, change oil often.

If the motor is tip top and not built 'loose' for dirt tracking, 5k per oil change will be fine as mentioned previously.

 

[turbojuiced]

No its just something I do personally. Like I said I know the oil is good for longer than that but I change it more frequently than usual.

And on a boosted car 5000miles is a long time to use oil especially when boosting alot you are more prone to getting blow by which causes the oil to lose its charactaristics. So like I said its based on a case by case scenario. Oil wont hold the same charactaristics as it did at 1000miles than at 5000miles on a boosted car. Thats pretty obvious.

And especially since your turbos are bb why would you leave oil in there that long? I know several people who had to rebuild there bb 50trims in the evo community for leaving there oil in for even over 4000miles. Granted the evo is a different car than a supra but the same concept applies.

The rule of thumb is 5000miles or 1 month under normal driving conditions. First off I dont drive even remotely close to 5000miles in one month and I would clasify my driving as severe not normal. So IMHO no your 5000miles rule is not conducive to all applications.

I've researched oils...a lot

What is obvious is you have NFI of what you're talking about. Everything you just said is pure speculation...no basis in fact...at all.

Additives don't "lose its charactaristics" after 1000 miles...or 5000 miles. Only an oil analysis will tell you what reality is about your oil's condition. I've run German Castrol 8,000 miles (with a SP61 turbo) without any problems, and I'm not the only one.

Got news for ya slick, a PAO based oil (like RP or German Castrol) is used in some of the most severe enviroments you can think of...an ester based oil (like Red Line) is the same stuff used in jet turbine engines. These enviroments are way more severe than any wimpy little auto engine turbo could ever produce...if the EVO crowd is losing turbos, it's not because they are leaving the oil in too long.

You can change your oil every day as far as I'm concerned, I just hope no one here ever listens to you. It is some of the most random BS I've heard in a long time when it comes to motor oil. Of course, ignorance is bliss huh?

Jdub, I understand you have a very informative link about lubricants and additives. However, I am going to stand by my statement and you can keep arguing with me till you are black and blue I really dont care because I know I am right and I have not exclaimed anything here that is factually wrong.

I did say oil can last longer than what I change it out at, thats just WHAT I DO PERSONALLY. There is nothing wrong with waiting 5000miles until doing an oil change if you want to do that then fine all I am saying is it is indeed FACTUALLY safer to change your oil more frequently. If you are going to argue that fact then I am done here.

On a side note why do you feel the need to flame people? Is it because you have the ability to ban people so you can? I mean I understand if I am coming out with wrong info, or I am posting illegal material or something however, I just dont understand your demeanor here? I know I am new here but not new to forums and cars. And as a mod myself on other forums I definitely dont act like that to members. I would like to think I am a pretty cool individual and easy to get along with and I really like getting to know other people I dunno I guess we just got started off on the wrong foot? I know there are 2 sides to a story so if you want to talk to me more about it feel free to pm me so we can get whatever it is alleviated. And again hope we can get along here. Take care sir :icon_bigg

I'm not flaming you...what you're saying is not based on fact. Have not seen a single one yet. And, when someone comes on here spouting "facts" without backing them up, you can expect this every time. Back up what you say and we will have no problem.

I may be a mod, but you can ask anyone here if I've banned them for debating with me. I take great offense you would even imply that I would. If you have a problem with me, take it up with SupraCentral.

 

[IHI-RHC7]

I used to get into the same arguments with J and JJ, I eventually did a ton of research myself, and realized that what I did personally was not backed by any real hard facts. I still feel weird about leaving oil in that long. I'm going with a bypass filtration setup on my next build, and I think I'll feel better about it then...

Negative bro dont have a problem with you and I think thats awesome of you that you like to have informatiVe discussions on topics. But these facts have been gone over many times in the evo community just do some research at evom.net. I am a mod there as well so I definitely understand where your coming from and I actually thank you for it.

Thanks again bro! Definitely looking forward to learning here and gaining even more knowledge. Btw, I do like your link about the lubricants. :thumbup:

yes sir, Its a learning process at each forum. And I really like getting know new people and learning from them and its a privilege for me to be here cause all of you guys here seem so awesome. I cant wait to one of these days and have a meet one day and just chill.

And yea I personally dont like leaving my oil in very long. And I just love always keeping really clean oil in my cars. And although it does seem like a waiste, to me its money well spent. I just recently added a oil catch can and a oil cooler so I will probably start changing it even later but still its always been soemthing I have been anal about for sure lol. :biglaugh:

I just installed my new engine, And did some loading on the rings. I let it warm up completely and cool down twice, then took it out and ran it up and dragged it down from 1500rpms, to 4000 rpms, about 15 times, and not over 3psi boost. It wasn't exactly the way that one thread states to do it, but I couldn't get out on the highway, so I couldn't do runs up to highway speeds. Seems good so far, though. no smoke of any color, either cold or warm. I will try to get it on the highway tomorrow for some longer load times.
