Hi guys
I have an 07 GT-B and on cold start ups there is a touch of blue smoke on start up. Car drives fine and no oil usage what so ever however a cold compression check revealed #4 was down (100) whilst the other 3 cylinders were 150. I am thinking it is a valve issue - what do you guys think? I am assuming a leak down down will show the exact picture of what is happening.
Cheers
