Hey guys,

I did a compression test on my 1987 TurboII today. Test was done w/ a compression tester that had been modified for a rotary by removing the valve so you didn't have to hold it open while cranking it over.

So here are the results:

front rotor: between 110 - 105 psi, 3 even pulses (leading plug hole)
rear rotor: between 110 - 105 psi, 3 even pulses (leading plug hole)

Car has 100,500 original miles on it. I bought it @ 54k original miles about a year and a half ago pretty much bone stock w/ Ronal wheels that were powdercoated the chasis color.

Mods that I have done or have w/ friends that have been on the car for about a year or so:

I have some really bad exhaust leaks on the rear cover of the turbo and the other day started sound like it was "camming" <- closest reference to explain it. lol. or lobing like it was ported. Especially in 1st gear or idling. Could this be that leak getting worse or a vacuum leak that sprang up and has gotten bad? It sounds pretty strange and just started the other night.

anywho, just thought I would share.
