Do I really need a rebuild???
So I got my TII two weeks ago, the engine was supposedly rebuilt and street ported between 2,000 - 3,000 miles ago and everything seemed fine except for a hot start problem (which after doing some forum research I had attributed to leaky injecotrs or something of the like). It would start fine cold, but once it got hot...I had to push start it (waiting might have helped, but I never had the patience, and I kept a friend w/ me 
)
I took it too my mechanic for a check up before I left town and he tried some new injectors but apparently the problem is being caused by weak seal springs not injectors
. He said that they (the springs) work fine when cold, but lose their "springyness" after they get warm thus causing low compression aka no start. Is this common?
When he did a compression test it showed 60psi across both rotors. I know this is too low, but isn't it odd that they would have the same low compression? Also I'm assuming that this is occurring outside of the "break in period" for a rebuilt motor, so that couldn't have anything to do with the low compression could it? I just don't wanna believe that it could have been that shitty a rebuild to need an overhaul when it's barely out of the break in. What else could it be ?!?!?!?!
Plus, @ $1500 a rebuild is no drop in the bucket.
Any ideas on what else to check would be greatly appreciated.
P.S.- sorry for the long post, just tryin to be informative.

All he said was 60 psi? I don't trust too many mechs giving me compression numbers. I want three sets for each rotor, a warm motor, and the throttle wide open. Sounds strange though......sorry I can't be of much help.

i blow a apex 2 weeks ago on a 3k rebuild i bot but the guy that sold me the car timed it all wrong and driving it 300 mile home did it in so i know your pain. if your geting a full rebuild for $1500 flat from a shop then take it. have 2 friend do it, it's costing me $1600-1800 and taking 3 weeks so far sense there doing it around work and rain and that reusing all the o rings, corner seals/springs. have to get a new rear rotor and housing =(
