I was out of town over thanksgiving and my brother in law was instructed too start my car every day and let it run for about 5 minutes..... Well he did that but i guess he was revving the engine up into the high rpms and it smokes a little at high rpms, well he wasn't aware of this and he thought he had f'd something up, well he ran to walmart and bought "no smoke" and put it in the car to try and "fix" the problem.....well what are the negative effects of this? I am going to change the oil but he ran the car for 5 days with it in there......what could it have done to the motor? How screwed am i?

Probably not a damn thing.....but get that **** outa there..all that stop leak **** is garbage IMO.

Just checking, you said it did smoke in high rpm's BEFORE right?

yeah i have some lazy oil control rings....it lets out a nice cloud of bluie greyie smoke on high rpm decel only....... at least i think it's oil control rings i really don't know, she just has to make it another year till i can do the T2 swap....any thoughts on the smoke?

I wouldn't worry about it too much. I had an 87NA that smoked really bad above 4500rpms, we didn't feel like rebuilding the engine at the time so we just put in a bunch of that Smoke-B-Gone stuff over a couple of weeks. It actually worked pretty good, it would still smoke at high rpm's but the smoking at startup was gone. I didn't notice any ill effects of using that stuff, and the car ran for another 4 years, so I wouldn't worry too much. But I would proably do like the above guy said and change the oil.

huh i didnt think that stuff would work for our cars. what did you use bacouse my car does that same thing. after about 5k it smokes on deceleration.

What about when the metering oil pump squirts in the combustion chamber? Won't that stuff give off a weird by-product?

Hehehe, that's pretty funny.

People have been putting thickeners (mostly Motor Honey) into rotary engines for years to keep oil from blowing out of a worn engine, so if it was just regular No Smoke, then I don't see any problem with that. The No Smoke & Stop Leak may not be such a good idea, but I am not familiar with this product. Stop leak products are generally a bad idea, especially in the cooling system.

He didn't say it was a "stop leak" product (which do suck by the way), he said it was a "no smoke" product.

All it does is thicken up the oil. If it was summertime, I'd leave it in there. But since winter is coming, I'd change it to a thinner oil anyway.

Mine would smoke under load, and under decel. It didn't completely take care of the smoke, but it made it where the car was driveable. Until I put that stuff in the car, it would smoke really bad at idle, I smoked out an intersection so bad, one of the people in the car next to me called my pizza delivery store that I worked for and complained to the manager about my car. After I put that stuff in, the car didn't smoke at idle. Well It smoked less and less till it all but stopped.

I should clarify...

Bardahl makes two similar products:

1) "No-Smoke"
2) "No-Smoke & Stop Leak"

He just said it was no smoke, which is probably the first product listed, but could also have been the second product.

Good point. "No Smoke" generally doubles the oil's viscosity index.

so what would you recomend???

In '98 I put in a $200 junkyard motor w/ perfect compression into my then dead motor'd FC...it ran well but smoked a LOT. After about a week of driving with STP stop smoke it was alllll gone. I added 1 bottle a year with my tune up before each inspection (which I passed) and I've put 40K on the motor since then...the car still runs very well and only a few weeks ago I noticed a little smoke at startup - matters not since I have a Kevin Landers full TII swap w/ Greddy FMIC and HKS FCON sitting in my shop waiting for installation as well as my daily driver GVR4 to get me around (hehe w/ 350hp it gets there pretty quickly) I wouldn't worry about it but if u want peace of mind change your oil, toss on a fresh filter and put in the stop smoke yourself, this stuff really works...I used it with 20W50 Castrol with great results and my car gets driven HARD. good luck

i wouldn't have even worried about cranking the car over the course of five days, lord.

but i don't think it's going to matter. your oil control rings are already fucked, this won't **** them up any more

Evil Aviator

Who, me? I recommend that he just changes the oil like a regular oil change. That will remove all of the No-Smoke except for the small amount in the oil cooler. Were it not for the cold weather, I would say to just leave it in. I use Motor Honey in my 1Gen's worn engine because that's the only way to keep all the oil from blowing out the exhaust, lol.
