Hey guy's, i appologise in advance for the vagueness of this post but when i was changing the oil this arvo i had a look up behind the engine and there was a fair bit of oil all on the runners going from the intake manifold to the block (supplies the cylinder's with oxygen, don't know their name). Anywho it was mostly on all the nuts that hold those runners on. The oil change cap was screwed tightly on and I couldn't think of any seal that is back there that could have gone and isn't a real pain to change. Just thought i'd check to see if anyone had any idea. Cheers.

^^thats right.
prolly your valve cover gasket leaking

hey what is involved when changing you valve cover gasket like how do you take it off

Yeah I have the same leak, the whole back of the head has oil on it....

Did you check the color of the oil, could be power steering pump oil, i notice that yesterday on my celi, but still dont know if where is coming the oil.

I only had a quick look but i'm pretty sure it's engine oil. The back of the valve cover gasket makes sense. I might get under there with a can of degreaser and try and isolate it then look into changing it. Thanks for your help.

Well i did that this afternoon, and yes was the valve cover gasket, and make sense, in front i dont have leaks, but the engine had some angle and the oil that its in the head are in the back of the head.

I think mine's leaking too. Probably going to change it in shop class next wednesday

also, if u ever get an oil leak on the side/back of ur head, check the O-ring on ur distrubutor shaft. Its a $5.00 part from Toyota. Cost me about $20 in oil and alot of heaches.
