Hello all,

First of all I want you to know I have been reading everything I can on the 22R motor. Specifically that which pertains to the timing chain and head gasket. I have what seems to be a rather unique problem. I bought a little 85 regular cab 4x4 about 2 weeks ago. that owner said that it ran rough and did not have much power. I was really stoked to have a chance to buy it so I asked him what he wanted for it. He told me he had an offer of $800 and If I would do better than that it would be mine. I offered $850 and went to get the dough. When I looked at it it was running rough. I turned out one of the spark plug wire boots was cut and was arcing to the head so the cylinder was not firing. I turn the boot away from the head and the current flowed through and the truck instantly ran better. I checked the oil and it was dirty but fine ( or so I thought). I got the money and did the transaction. when I went and started it for the first time after I bought it I noticed it was spewing white smoke that had the distinct smell of burning antifreeze. No big deal I got it cheap and the parts are worth more than what I paid. I got it home (2 blocks) and it was smoking like crazy. I did a basic check (pulled the valve cover, oil looked like chocolate milk)and determined that the headgasket had gone. I went about tearing down the engine to remove the head. I sent the head to my buddy who is a turbine tech, so he could clean it and measure it for warpage.The head is not warped. In the meantime I talked to another good buddy who is a mechanic and owns a shop. he told me toyota 22R headgaskets rarely fail. more likely it was a loose timing chain had worn through the timing cover and coolant was leaking in there. this made sense as cyl #1 was steam cleaned from coolant. cly 2 not so much but still cleaned. Cyl 3 not so much and cly4 not at all. So I figured it was the timing cover and went about disassembling that. Since the FSM calls for the head to come of for proper replacement, no worries. well this afternoon I pulled the timing cover and I am stumped. That is why I am posting. The timing cover is in perfect shape. When I pulled the cover off. pieces of the nylon chain guide from the drivers side were all over. all large enough that they got caught above the oil pan. I collected them up and set them aside. that explains the loose timing chain. But where is the coolant coming from??? any Ideas. I was worried that the block may be cracked but the coolant seemed ok and it never gets that cold where I am. I am going to get the head surfaced and tested at the machine shop. Do the valves have to come out on a 22R head to pressure test or surface it? Thank for any help in advance. <img src="/forums/images/graemlins/cheers.gif" alt="" />
