When I bought the X it had the guides failed and no oil pressure...that said,I couldn't be sure about the previous guy stopping it right away it lost the pressure or driving for a while just like that,before the guides overheated and failed.

In your case if the oil pressure is still there,I personally see no reason to spend more money than needed.Only if the compression test shows good numbers.


If you go the rebuild road get a kit from these guys.The generic chinese copies are not easy to perform the timing alone.
Every guy that used this kit had positive and trouble free experience.Some of them had to get it anyways to retime after using chinese counterfeits.
