Hi guys, if this is in the wrong section sorry. Its a very sad day today, car has been down all year long, big build with quality parts, quality work, and after a mere 70 miles of low boost break in driving shes starting to knock, and theres debris in the oil filter. Its for sure bottom end, its load dependent, knocks louder under throttle. I just wanted to go through my parts list and see if anyone wouldve done anything different or if theres any red flags to anyone? This is my first major 4G63 build (not at all my first engine tho) Craziest thing is the block/crank is out of the car Ive had for 10 years, driven daily, no issues, I just freshened everything up, so its not like Ive got a basket case.
Obviously I wont know for sure what went wrong until Im back in the engine but if theres anything you guys would change I'd appreciate it, thanks. Mainly should I of used an HLA regulator?
6 Bolt block, ARP mains, line honed, .020 bored, BSE, crank scraper, stock crank, eagle H beam, wiseco hd 1400, rings .020/.022 gap, ACL tri metals, all balanced
2G head, deburred, teardrop mod, standard ARPs, all stud holes drilled to 13mm, and oil feed hole drilled to 9/16
90 FFOFH, 3G lifters, turbo is fed from the head, no restrictor.
Ive ran a lot of this previously for years without an issue, what I changed was a built 2G head, pistons/rods. Same turbo, same OFH, same oil pump, I hadnt had a failure before and everything checked out good. The most my engine saw was 7k, twice, the last night before it started knocking. Was on low boost, tuning it out, I was being smart and easy on it. It was primed beforehand.
