Hey guys I have a 08 Silverado 5.3 I bought a couple weeks ago it has 293k im not 100% sure it’s the original engine but I belive it is idk how long it’s had a collap lifter but I looked at it a couple months ago and then bought it a month ago so it’s atleast had it that long I was wondering should I try to uncollapse it or it might already be beyond repair I already ordered the kit
