Years back I had a local shop rebuild mine. It was awful. It had piston slap when cold and of course burned a lot of oil. They machined if for extra compression (their decision, not mine) and it pinged like crazy on all gas types.

I had a Jasper put in about a year ago. The only thing I don't like about it is that it burns at least a qt of oil every 1k miles. I thought maybe it would break-in at some point but it's gone 15k and the oil consumption is still strong. They told me that that consumption was within Toyota's specs. I just know it could be a lot better. I am going to put in a straight Toyota OEM long block next. The factory sells a completed short block and you can buy the separate pieces for the head. I just won't trust any aftermarket engines anymore. I want to get the last of the great japanese engines before they stop making replacement parts! <img src="/forums/images/graemlins/smile.gif" alt="" />
