Thanks for replies guys. Cam is a cam tec 413b. 270 duration. 242.50. 112lsa 10.8mm lift. was told by mechanic who checked the motor that compression good and in line with where it should be due to motor build and cams/top end. But felt leak down wasn't right? He did say as the vehicle spent alot of time sitting round since being built valves may not being seated/sealing right? Something along those lines. Haven't seen the car in person as it's interstate but am going to inspect next week. Car currently on e85 running 470hp at wheels on 23psi with hks gtss turbos. Engine was built by a reputable shop. Compression check was done warm and cold but I'm unsure of leak down. Is there a process of elimination to determine if leak down results are through top end? Appreciate the replies.

Hey Team. First time posting after many years out of the gtr scene and now looking to get back into it. Been hunting for a while for a 32 and looked at a few, but finally Found one that I’m pretty interested in and have just had a compression and leak down test completed on the motor. Hoping to get some advise or feedback. So thanks to all in advance! Motor in the cars a reasonably freshly built. 2.8 stroker. compression came back at a consistent 130 across all cylinders. leakdown results as follows. Cylinder 1 - 18% cylinder 2 - 22% cylinder 3 - 13% cylinder 4 - 13% cylinder 5 - 18% cylinder 6 - 22% motors done around 2k km from being built, over last couple of years so not driven often. Spoke with mechanic who did testing and he said these numbers where ok, but they seem a bit high/all over the place to me. Any help, greatly appreciated. can provide more details on motor build or other info if needed? cheers. O.
