85 4runner 22re issues

[_x_ramon_x_]

Bought the 4runner 6 months ago and thought maybe the timing was just off because its under powered. Starts and runs just has no power after 3 or 4k rpm. Throwing a code 12 for knock sensor/timing. (replaced the sensor)

Only other issues are an exhaust leak and changed the oil which immediately turned black and has a fuel like odor.

Idles great and doesnt have any knocking or out of ordinary sounds. Does blow white smoke when revving in neutral past 4k rpm.

Any advice would be appreciated. Have not driven it more than 2 miles since purchased and would really like to be able to enjoy it.

Im sitting on a 5vz and waiting to swap once funds and time allows but it may be another 6 months before that will happen.

what were your compression test results?

Have you done any testing for a blown head gasket at all?
Don’t know a whole lot but have heard white smoke out of the exhaust is a sign of possible head gasket problems, that may even explain the oil problems as well.

I agree with Dropzone. I think a compression test may reveal a lot. I think if you potentially have bad rings that you may get some blow-by and therefore why your oil seems to smell like fuel. Or, it should also reveal if there's a head gasket issue. Let us know what the test results show.

If you think it's a blown head-gasket, remove the rad cap and fill with water and then spin engine over usually the water will blow out the rad if gasket is blown.
