Well here is a little history first (since haven't posted on this board much - use to a lot on cnet (celica.net) back in the day though....
I had done a 3sgte engine swap and had a buddy do all the wiring for me (about 3 years ago). After finishing the mechanical stuff and putting th engine in, I found out the wiring was hosed. I took it to a shop to get it looked at and they put a microtech standalone ecu in it. I finally got it running and it ran great for about 2 hours of usage and then just died on me. I haven't been able to restart it since then (but haven't been working on it too much)... The pistons all seem to have really low compression (all around 90-100 psi). I am wondering if 1. what the compression should be. 2. if it is low, why is it low on all of the cylinders - does this mean the head gasket may have been put on wrong?? What could this imply? Thanks for any assistance. Ben |

I've never heard this. How could you never get as good of a seal? What if I replace my headgasket with a metal one? I've been debating plaining the head and putting in a metal head gasket. Sorry for the thread highjack Celica at GT. Wish I could help you, but I don't know enough. -------------------- Live Free, Be Happy

Sorry for the thread highjack Celica at GT. Wish I could help you, but I don't know enough. if the mating surfaces are not PERFECTLY flat, and SUPER clean, especially with a MHG, its will prolly leak at some point. when your motor was at the factory being built, everything was brand new, and perfectly smooth and clean.  i wouldnt say "never" get a good seal, but without the proper prep work (IE: machine work ect.) things are bound to go wrong at some point.
