Do I have a BHG? 2 Videos included!

[Alpha WereFox]

Alright heres the story. A few weeks ago, if you saw my post when my belts flew off, I overheated the Supra. Got belts on it, drove it around more. Then I drained all the coolant out and put water back in. Burped it of course, and drove it more. Then I went to the Philly Supra meet on Sunday, as you saw my car there in my pics and other peoples, which was a 75 mile trip est, and about 90 min ride there. I got there and home with no problems. So today I drained my water, and found alot of oil in it. I'd say the water was in the car for about 300 miles give or take. Keep in mind it was JUST water when I put it in and flushed it out real good.

So here's a pic of what drained out and a pic inside the bottle so you can see the lovely color better!

Ok so now that you seen that, you can see I clearly have a problem. Now remember the car does NOT overheat at all, but does run a lil warmer, prolly cuz its hotter out now of course. So I reflushed the motor and radiator again, and burped it all out, and did 2 tests. One was holding the RPMs at 4k for a few mins and see if she got hotter. Not much different there. Then I took her for a drive and still, nothing.

Here's the 2 videos, both under 5mb each.

Video: Holding RPMs at 4 grand for a few mins.

Video 2: Driving around my area a bit.

So after all this, my question are:
1. BHG? 2. Cracked block? 3. Cracked head?

Also is it okay in your opinon to drive the car in its current condition as long as it does't overheat? Should I try some kind of BHG sealer stuff? If so what kind do you recommend?

I'm trying to sell the car for $1k usd at the moment if anyone is interested.

Let me know Supraholics! :1zhelp:

210* is that normal operating temp? I remember putting in a 180* thermostat in mine...

 

[Alpha WereFox]

That's what the Faze temp guage always said since I put it in my car months ago, so I guess!

if you just put water in your car its probally brown from rust.

 

[Burntz]

so you checked your water...

did you check your oil? lol

To really know if you have BHG(100%) get the leak down test kit from napa A.K.A. 7M BHG kit. Also is there chocolate milk in the valve cover cap on oil level stick? white smoke coming out exhaust from your video i dont see any signs though of a BHG.

Yea, those videos don't show anything...although I don't know why holding your engine at 4k rpms would show a BHG... :dunno:

But yea, that water is full of rust, and since you were running straight water, I'm not surprised at all. 300 miles is a LONG TIME to be running straight water...it will start to rust out the engine very fast.

A weird and quick spot test for rust is to drop a piece of red oak into it for a half an hour, then pull it out and let it dry. If it turns blackish, then you've got a bunch of rust, because the iron reacts with the tannins in the wood to produce the color. Really.

^ I love your home remedy & creativity sound advice people would have never thought of.

 

[Alpha WereFox]

The oil looks fine, dirty cuz it needs a oil change soon. But it doesn't seem milky at all. And it really doesn't smoke anything but black I was told. And I held the rpms cuz if it had a BHG I thought it would overheat, no? Ok, so if it is a crapload of rust, what should I do to get rid of it?

 

[Alpha WereFox]

Alright So i asked my dad and he also said rust. Is there anyway to remove it from the cooling system?

Thanks. Bachelor's and Master's degrees in Wood Science come in handy in the weirdest ways...

Read your other thread....?

have it flushed,and by flushed i mean go to a jiffy lube or something of the sort and have it flushed. draining it yourself will only remove some of the fluid.

 

[Evilempire1.3JZ-GTE]

^ they sell kits to flush it at autoparts stores by the way jiffy lube sucks they charged my wife like 300$ to change the oil & change auto trans fluide.

 

[bluedragon17]

yeah there expensive as hell. I used to work there and said f**k this its so not worth the work for the little money.

the only thing i have seen at autozone has been a fluid to flush the radiator. just because i havent seen it doesnt meen they dont have it. but pretty much you have to have something to pump all of the fluid out, if you just drain the rad you will only be getting half of the fluid out.

ok ok here's how you do the whole radiator deal correctly and best way to do it yourself (this is from my experience and has worked perfectly for me). I have a clean car and the mileage prove it. Everything for the most part is original. I hardly go the cheap route with the car and do it right the first. I'm just picky and anal like that with a lot of projects I work on.

Items to Purchase:
-Toyota Radiator Fluid (only can be bought at the dealership; the fluid color is red)
-New thermostat w/ new thermostat gasket (can be purchased from local autoparts store i.e. Kragen, AutoZone)
-Prestone Super Radiator Flush (http://www.prestone.com/products/coolingSystemTreatments.php#coolingSystemTreatments1) be sure to READ THE DIRECTIONS EXACTLY as to how long to leave the radiator flush in the system. Fluid is corrosive if left in there a long time.
-DI water (distilled water) the reason is because there are hardly any minerals in DI water compared to tap water or which ever water you are going to use. The last thing you want to do is do the job and have mineral deposits in your cooling system later down the line.
- Purchase a new radiator cap


Steps: would be better off if you had 1 extra person helping you but you could manage by yourself. Also, whenever the engine is running be sure to have the heater on high heat with the heat blowing. This is for getting the old coolant out of the heater core

1. Drain the cooling system
2. Drain the radiator reservoir (I would be a very very good idea to take a brush and clean the inside of the reservoir and this time)
3. Put back on the reservoir and fill it half way with only water
4. With the drain plug off the radiator, take your outside water hose and pour water into the radiator.
5. Turn on the engine. Be sure water is constantly being pour into the cooling system.
6. Run the engine for about 5 minutes
7. Turn off the engine and stop the water.
8. Wait for most of the water to stop draining and put back on the drain plug.
9. Take the Prestone Super Radiator Flush fluid and pour all of it into the radiator. Fill the rest of the radiator with the water from the outside water hose.
10. Once filled, put the radiator cap back on and turn on the engine.
11. This is where reading the coolant flush direction comes in. Run the engine exactly how long the directions till you too. Some flushes are 15-20 minutes. Others are for like half-a-day. The bottle should tell you how long. Usually if the flush says half a day (~6 hours), you can drive it around to do whatever errands you have.
12. Once the time is up, drain the cooling system and the reservoir again and repeat steps 4-7
13. Now from here you can go ahead and change the thermostat with a new one.
14. Put the drain plug back on the radiator and put back on the reservoir as well.
15. Take the Toyota Radiator Fluid that you bought at the dealership and DI water and mix a 50/50 solution in another clean container or bottle. By 50/50 I mean half of the new solution is DI water and the other half is the concentrated Toyota Radiator Fluid. This ratio though honestly depends on your location and temperature range.
15. Once you have your mix already done, pour it into the radiator until you can’t fill it up anymore. Once filled to the top, put on the new radiator cap and close it.
16. Fill the reservoir with the water/radiator fluid mix and close it.
17. Turn on the engine and let the car warm up for like 5 minutes. Keep an eye on the temperature gauge and make sure it doesn’t get high. If it does, turn off the engine ASAP. That is definitely not good if the temperature gets high and that means the cooling system needs to be looked into more.
18. After about a week of driving the supra, check the reservoir and see where it is at. If the fluid went down a little bit, that’s ok. That means the cooling system was removing the air pockets in the system. If the reservoir fluid is still going down after a month, then you could have a possible leak in the system or a hint of the infamous BHG.

Here’s a pic of my MKIII to show you have I taken good care of the car since I have been driving. My family and I have had the car since 1988. Yes you read right. 1988. We are the second owners and the car now has 240,000 miles on it. Almost everything is original, even the paint.
