A little history on this car, I bought the car with a broken timing chain from a mechanic. They had stripped out the inside of the cylinder head bolts, where they try to remove them. The threads on the bolts were ok. I removed the head and had it machined and the bent valves replaced. I put in the steel inserts after reading about the problems the 2.4 has with head bolts stripping out. (You know a oz of prevention, since I had the head off) Got a gasket set and put the timing chain on, making sure I had all the correct marks lined up. I believe this is where the mechanic made their mistake, lining up the chain on the wrong mark of the cam, because their are two marks on it.
This is what is happening, cooling fans will not come on except when the AC is turned on and they will go off when the AC is turned off, otherwise the car acts like it will over heat. The temp gauge inside the dash shows the hand about half way to hot. When this happens the engine runs very rough and sounds badly. When first starting up the motor sounds great and quiet, but in a minute or two the engine starts making a loud clacking sound from the head. The head does not have the hydraulic lifters but the fixed ones.
When I first start it up it runs good, three different times I test drove it about a mile down the road, the engine started running rough as the temperature gauge on the dash was reaching mid-way. I turned the car around and started back home. As I am driving back into the garage, the motor was sounding badly and the gauge was mid way now. After cooling down, I check fluids to make sure the head did not warp. When the motor is running, taking the oil filler cap off, there is a lot of blow-by coming out. I am not sure if this is normal for Camry's.
This is what I have done. Replaced the fans (because the radiator fan was bad, after hooking them up to directly to the battery). I checked all the grounds, including the one under the intake, checked the fuses, checked relays when 12vots to the relay and used a ohm meter to see if it made contact when activated. On the three fan relays. Replaced and tested the new radiator sensor with a pot of water on the cooking stove and temp gauge and ohm meter. Unplug the radiator sensor while the car is running, the fans will come on, but go off as soon as it is plug back in. Replaced the thermostat. Did a block test, was ok. The compression is as follows, the motor would start each time
what can I do next, before I burn the motor up trying to fix it?
have the same problem?
