guys i need some help. i just bought a 95 Z with a 396 in it and whenever i get on it smoke comes from the shift boot area and it smells like anti-freeze burning. idk what the deal is. i know its not the clutch or anything cuz i'm not ridin it at all. idk if the anti-freeze burp tank over flows and gets on something causing it to smoke cuz the front end raises up quit a bit, but idk what to do or if i should worry. any info would be great thanks guys.

Thats a new one on me.

 

what colour is the smoke? perhaps you have a leak in your y pipe area?

 

I wouldn't think antifreeze from the over flow would make smoke. Steam maybe. I would check your y pipe and see if it's got oil spots on it. You may have a bad rear main seal or something.

 

it is more like steam i guess cuz it doesn't stay in my car it just goes away. but it does smell like antifreeze. how mush is a bad rear main seal and what does it do? i have a slight oil leak everytime i shut off the engine it leaves a little. the local shop said that it was comin from up top cuz there is oil all over my long tubes and all the way down, so idk. i just had the oil changed so i'm hopin that stops, cuz the guy i bought it from put mobile 1 10w 30 and then race weight 40 from royaly purple so idk if the race weight thinned it out too much i just put in mobile 1 5W 30. any help is greatly appreciated. thanks

 

Does your clutch slip at all, I've smelled burning clutches that hinted at smelling like antifreeze.

 

there is no slippin in the clutch at all, thats what i thought it was too. the whole motor tranny drive live is all new with only about 8k miles on the whole set up.

 

You've got me stumped, unless something is leaking down onto your y pipe?!

 

I have no steam or smoke, but I get the smell of anti-freeze at high speeds or if I get on it on the highway.

It's only happened once (over 124 mph)

but, I know what your talking about. I have not tracked the problem down either.

 

i know what it is!!!.....the coolant croossover tube on the rear of the heads...it is the ONLY place were coolant could leak from and burn on the exhaust, the ONLY place....

they need to be torqued to 30ft pounds

ill take a beer now

 

well what do i need to do to stop it? should i take it to the local shop and have them torqe it? is this a major job and how much are we talkin here? hopefully not that much and how bad is it on the motor or what exactly does it do? thanks

 

well basically, its not that hard to quite, the problem is though, that the rear of the heads are so damn far under the cowl. you may have to do it underneth...i cant remeber what size it is, but get a wrench on there and tighten it down...just get it nice and snug....

that tube is like an air bleed..pockets of air that may be trapped here and there are "removed" out of the heads....right now its not really hurting anyhting except your coolant level...its it wont fall that fast...just take care of it...

i have an LT4 motor in my 91 GTA so getting to that tube is very easy for me...btu the 4th gens have the motor under the dash, so its gonna be harder for u to get to it

 

Does anyone else have any imput on the situation? or is he right?? i'm not saying he's wrong though either so don't get pissed at me.

 

hes wrong!!!!...sorry i had to be the first one to call :BS: lo..seriously though, unless your heads had a cracked gasket, then this is the only place coolant could be burning from under the car
