Hi, reading your thread, I can see you are not well up on the servicing of autos, You state the service costs a lot, I agree but take it from me, it is going to cost you a hell of a lot should you " **** Up" To do the job right depending on the year, make of your car, there are seals to change, there are sump "02 rings to replace, but the most important, DO YOU VALUE YOUR LIFE?? If you have not undertaken this job before, and before it MAY TAKE YOUR LIFE, Think about it, Talking B-----------T Iv seen it, Iv heard it.
