With no tester in the hole in #2, can you hear/feel and air pulses coming out? If not, sorry, rebuild time.

Kevins the least expensive and one of the very best. And yes, I'm SUCKING UP 'cause once again he's gonna have to bail me out on my clutch problem!

it runs smooth. it has trouble idleing and it feels like it has a huge power loss. im changing the oil now it is thin with a good amount of gas in it. this car is absolutly perfect except for the poor performance and idle. please dont tell me i need an engine

They guy could have beat the hell out of the motor, my motor went with only 98k miles on it, and the interior and exterior was in really good shape.

when I bought the first jspec, it didnt have any comp on the second rotor.... the guy said that when he picked the engine he did a comp test and it had good comp... he said that the seals get stuck from sitting too long and that carbon holds the seals in.... I personally never seen a motor loose 100% comp from sitting for a while...he quickly gave me another motor so I didnt complain at all...
