[Supras] CPS Leaking on my 87t

[Harley]

 I was wandering if there is supposed to be an O-Ring at the very beginning of the CPS shaft. Where the cps connects to the head.
    My CPS was leaking a ton of oil for a long time and i couldn't figure out why. So I put an O-Ring at the beginning of the shaft and tightened it down and it seemed to have worked to stop the oil from leaking. The CPS doesn't mount flush anymore but it is still tight.
    The biggest problem I am having right now is an exhaust leak. The gasket between the Turbo and the manifold blew out due to loose bolts. I tightened the bolts but it still is leaking. Its also leaking from the downpipe to turbo The gsket looks intact but its leaking out the top. If anyone has any extra exhaust gaskets, I would like to buy them from you. :)

    Thanks guys!
