Unusual Problem - Oil in Radiator

[ciresmis]

My truck quit the other day, and I found oil in the radiator. There was no oil in the block and no oil on the dipstick but no water residue either. The engine turns over but does not start. I cannot get my code reader to work apparently because the motor never started running. I'm not sure. I had it towed to my home. Another inspection found some oil in the block. I then had it towed to my mechanic this morning. He said there was no oil in the radiator at all, but the block was a quart low. He thought it might be the oil cooler, but he found no oil in the radiator and no oil residue in the radiator at all. The fuse had blown that controlled the fuel injectors, but replacing it had no effect. I have had the fuel pump replaced, and he thought that might be the problem. He also thinks it may be a computer issue. He will do more tomorrow to find out. In the meantime I was wondering if anyone had any suggestions I could pass along to him. I drive a 2000 Tundra V-8 2WD. 115K miles. Two oxygen sensors were out and were scheduled to be replaced later this month. Thanks in advance for any guidance concerning this problem. - Eric

I'm no mechanic but every time I've seen something like that it's been a head gasket

Eric,
Really hard to say. if you didn't see any oil on the dipstick, usually means it was lower than a quart. usually if you cracked a head or head gasket the oil should look milky. Not sure if the timing belt was changed at 90k , if it has never been changed, It could very well have slipped timing? If you are blowing fuses could be something in the electrical. Really hard to say without seeing it myself. Good luck, I hope it is nothing major.
