might not be the lands, but it could very well be the oil seals if that much oil is coming out.

well, thats all he had available at the time. couldve just simply said "try a leakdown test".
but then you would have missed the bit about that mad tyte JDM breather.

I wouldn't go as far as to say it is bad compression, but for an SR it is alright. now 140 on a KA might be cause for concern.

I told you either the rings were gone or the valve seals are gone, doesn't have to be a compression ring to leak.
I would lean more to the rings side. If it was valve seals, there would be smoke

I don't know, last time I had my head checked, "they" said it was good, but to me, a 10% drop in compression isn't a good thing. It isn't a "OMG that's terrible" thing, but I sure wouldn't write home and tell momma about how great my compression is when it is 10% lower than stock.
