Ok my 95 T100 has this gunk in the radiator. Im not sure what it is. its like oil or something. The other day I opened the cap and found a little piece of rubber! I have completely flushed the coolant system and the problem still remains. Could it be anything else?

It's not the head gasket! Maybe...

Drain some coolant and oil out into separate clear containers. Does it look like chocolate milk? Is this engine the 3.4L 5vz-fe?

White smoke out the exhaust? Coolant or oil level changing? What does the underside of the oil fill cap look like?

MUD-LIGHT

Yea the coolant is kinda milky. Oil looks fine. The backside of the oil cap is clean.

MUD-LIGHT

And yes its the 3.4

It's not the head gasket.

There... I said it.

If its a standard its easy to tell. Drive down the highway untill you find a decent hill. Drive to the top, then start driving down. Leave it in gear and take your foot off the throttle. This closes the throttle plate and creates a rather large engine vaccum. After 10 seconds or so step on the gas and watch your rear view mirror for white smoke coming out the exhaust. If you see smoke. Head gasket. This isn't a definative test but it does work rather well for how much effort it takes. Plus you get to drive your toyota!

Thanks. Ill try this tomorrow!

You can also pull the spark plugs and see if one or more look a whole lot cleaner than the other ones. Water in the combustion chamber will steam clean the spark plug that is leaking...if it is leaking.

Snap some piccies and post them. Use the macro mode on the spark plug's business end.

I just replaced the spark plugs last week idk that they would show anything but ill take some pics today. Ill pull the plugs anyway, and ill get a picture of the coolant. When I pulled the old spark plugs they all looked decent no major fouling but they were not perfect. Looked normal to me. If this isn't the head gasket what else could I check?

MUD-LIGHT

Tried it today NO SMOKE! So thats good I did it about 5 times at different speeds and in different gears. Here are a few pics of my coolant. It was green a week ago!

you sir have a bad head gasket. I'm sorry for your loss. Unless its an auto and your trans fluid looks like diesel motor oil.... your engine oil is mixing with the coolant. I'll leave you alone now to be with your loved one.

nothingbetter

heh, ummm....forgot to tell you. My test only works for head gasket inbetween the coolant passages and cylinder. It doesnt' check between oil and coolant passages. And it would appear thats where your issue is judging by your coolant pics.

MUD-LIGHT

I figured it was but I was praying to god it wasn't! So there is no way it could be something ith the valves?

MUD-LIGHT

Whats the average price Im looking at any guesses

nothingbetter

no. The valves are only sealed to the oil system. They have no contact with coolant.

depends on how mechinically inclinded you are, just did a 3.4 headgasket at the shop and his bill was 2,300 for timing belt, heads, and gaskets and oil and coolant and all that

MUD-LIGHT

I know enough to get by but I have never done engine work like that. That is so expensive I wonder if I would be better off trying to get a rebuilt motor.

To be honest, that coolant looks like someone tried putting stop leak in the cooling system. All that grit looks like the remainder of the stop leak material.

I did mine a month ago, radiator, hoses, water pump, timing belt, pulleys, headgasket, valve cover gaskets, valve job, machine shop > heads, new injectors, plugs, wires, coolant (toyota red), thermostat (toyota oem) all the good stuff for a grand total of 1990$ so it varys
