Yea that kerosene flush most likely was not a good idea, I would not have ever cranked the engine over while that light was blinking. Kerosene isnt very thick and you most likely have damaged the head as well. Pull the valve cover off and see how it looks under there. As onepoint8tee said, it may be time to start looking for another engine

 

The low oil pressure light was not blinking when I was flushing the engine with kerosene.

(yep, most lilely was neglected at some point. i would def pull the pan, and if the light has been blinking you most likely need to change you main bearings as well as the rod bearings, which results in needind to the change the main seal and crank seal. A flashing light means absolutly do not start the car no matter what. That is the most serious warning light you can have)

So my question is, can I replce the bearings/seals that are mentioned above and prevent this engine change? How hard is it to replace and is it expensive?

 

I cant tell without seeing it, if u really ran kerosene I'm thinking your going to need to change the whole motor. kerosene is about as thin as water... i doubt it has any lubricative (not sure if its a word) properties.

If you only change those parts, parts are going to run you about 200-300 for just bearings, and seals for pulling the pan and crank. However you might as well re-ring it and hone it while your in there , so new valve cover gasket, head studs, head gasket, and since u need to pull the crank to change the main bearings, you should def do the timing belt and waterpump while your in there

 

tom knows all

 

I didn't run the engine on kerosene alone. I added half a quart to the oil that was already there. So i don't see how the kerosene could damage anything. There was oil pressure when the engine was run for about 10 min before being flushed an hour later.

 

ok well gl, all i know is that I fubard my turbo and bottom end from mixing a little blowby gas with the oil, so rip it apart and see whats going on

 

I don't understand your last post. Please be more clear on what you are tring to say.
Lets say that I drove for a few days with the oil pressure light blinking. And then I fixed the problem so now oil pressure is fine and light is off. Would I have to do anything in that case? That whining noise that the engine makes now is a "little" noise - can't describe it but now that you mention it - it could sound like a worn bearing as it speeds up with the rpms if throttle is pressed.

 

I would stop driving it until it was rebuilt. if a u spun a bearing or something metal pieces will break off into your oil. Any noise coming from the crank/bearing head area is def not something to be messing around with.

Above I said "goodluck, I had a very small amount of gas in my oil that got past the piston rings, and that caused the oil to be thin enough to ruin my rings, turbo, main and rod bearings"

 

Is there any write up or instructions of any sort on chaging the bearings anywhere?

 

not sure im sure if u have the bentley manual or whatever. I'm pretty sure u hafta pull the motor outta the car, unless the v6 is different
