OK ive got a 22r in a 1987 4runner and it is losing antifreez at an astonishing rate. I havent found any puddles under it and cant find any leaks. it lost about a gallon of coolent yesterday just driving to and from school and I filled it the night before. Also i found oil in the radiatr puke tank and a little water in the oil. I did a compression test and all the cylindirs were good so im doubting a head gasket but i still need to know were my coolent is going.
:cry: :cry:

 

Ever replaced the timming chain. If you did a compression check and it looks good. Then all bets are that the timming chain guides have broken and the chain has worn a hole in the the cover to the water pump. Get that fixed quickly and flush everything out afterwards with new fluids. I had that happen and it is not good.
Not a hard thing to fix if you can turn a wrench.

If it is the timming chain get the performance kit from enginebuilder.com it cost $64.00 + shipping and has the metal backed chain guides. He also has the Timming Cover in the Toyota Hot Licks section for $48.00 + shipping.
He has a great reputation on this and other boards for his products, many a happy customer.

Hope that helps,
Brad

 

How do you do that? Do you have a detailed website with instructions?

















gotta give you a hard time, you know that!

 

You lost me there Mo??

 

just being sarcastic, ignore me!

 

Your headgasket is gone. When the engine cools it will reseat some so the compression test won't show it. Get it fixed soon or you will find yourself sitting on the side of the road with a really blown gasket and the possibility of having overheated the motor to the point of warping the head or overheating the oil seal rings on the pistons. If you are losing coolant that fast, its going to happen very soon.

 

It's going to be the head gasket, almost assuredly. You can have a fine compression reading with a small coolant leak into the chamber. If you pull those plugs again, you're going to find one of them is much cleaner then the others. If you're still not convinced, go drive the truck and warm it up. Pull into you driveway, and leave the engine running. Open the hood. Partially remove the radiator cap and notice the change in the sound of the way the engine is running.

If a timing cover gets a hole in it from the timing chain, pressurized coolant flows into the oil, oil does not flow into the coolant from this hole. You would find your crankcase full of water.

 

Fox, When my timming chain broke thru the cover. I had coolant in the oil, and oil in the coolant. My rad and overflow bottle had to be cleaned because of the mess the oil left in there. The over flow bottle is still stained like chocolate from it. Just to let you know, speaking from unfortunate experience.

 

Just go in and do both. I have a (nasty) habit of replacing everything anytime I have to dig deep in a engine (or tranny, or differential, or...). Since you have to remove some of the timing components to pull the head and pulling the head makes timing chain replacement easier, the two operations are easily done together.

 

I just replaced the head gasket on a 1985 22re-c with the same symptoms. We replaced the timing chain, dampers (they were broke) and some fraile hoses. Wire brushed the piston tops and all the carbon off the compression chamber. Cleaned the hell out of the intake manafold, all the injectors and anything else we could find. Set valve lash and good to go.

85runner turned me onto this site www.engnbldr.com check it out.

Oh, and once we got in there it turned out to be one of those, shoulda done this and shoulda done thats.......next time.

 

Sorry for the jack. toy283, how many times have you had that x-cab on it's side? I seen the pics on you home page.

 

I'm not saying you can't get any oil into the cooling system when the timing chain cuts into the water passage in the cover. But the cooling system is under pressure, there is no oil pressure there. The only oil is what is flung/scraped off the timing chain. That's why the cooling system will dump itself into the crankcase, and only a little bit of oil will end up in the cooling system.
