Confused

happysupraowner:) · 05-21-2009, 07:00 AM

So like I posted before my car is ragging at the moment. Its smoking like crazy out the back, no smell to the smoke at all. I have no coolant overflow and my temp gauge does'nt go past halfway. What I want to know is if bad gas could possible cause the symptoms I'm having with my car? I bought gas at some out of the way mom and pop place and I think the gas had been there for years lol. I just don't know where to go with this thing. The compression test were fine on it. I just don't know what is causing it to smoke. It feels like it has lost a bit of power but other than that its fine. Thanks for any replies

I would check the oil just in case to see if it has any milky color to it...the 7M motors have a bad rep for BHG do to poor torquing by the manufactor... And the motor is great it will still run like a champ even though it does have a BHG...If not, then it could be a rich mixture causing the problem...also you can check your plugs to see if they are brown in color this will also let you know if you have a BHG, they should all look similar white and not brown if you do pull any with brown on it then that cylinder has been envaded by coolant due to a BHG...if I'm wrong I'm sure someone will correct me.

If you think it is bad gas. run it to empty. and put in Some premium Name brand gas. Make sure you use a good name gas.. many smaller gas stations have been known to water down their gas. I would recommend checking for bhg if that doesnt work.

what color is the smoke white, gray, black, blueish tint, that can tell you what your burning.

Its white with no smell at all. No plugs are brown. This car sucks lol.

Ok, then that means that your getting antifreeze in your cylinders some how, you might have a small leak in your head gasket and needs to be changed out. When the fuel mixes with antifreeze it produces a white smoke or steam from the exhaust. Check your antifreeze to see if you have any mixture of oil there in your coolant and check the oil filler cap and the dipstick also for any thing that looks brown or dark chocolate in color. But ultimately that's what's wrong is a BHG.

I changed the oil when I started to first notice it, nothing milky, white or anything. I don't know what else it could be.

i would put money on it being a blown head gasket. buy ARP headstuds to bolt the new gasket down and never have to worrie again

Yeah, its a bhg. I let her run just a bit ago for about 35 mins, and its started running very very hut. Gonna start taking the motor apart on weds. I know its gonna suck lol. I have no idea what I'm going to be doing lol. Its going to cost way to much to take it to someone. The only thing I'm worried about is the timing being a issue.

You should look up some threads about blown head gaskets in the forum there is one especially from Ihatehacks http://www.toyota-supra.info/forums/...ir-w-pics.html it's a long thread but pretty detailed along with pictures, that should get you started. And also if you have any more questions feel free to ask.
