Was trying to hold off on making a thread but here we are. 93 244+t. blah blah specs
TL;DR: iPd turbo cam been installed and great. Reshimmed to exact spec and now it makes noises. Is it the shims fault, or maybe a normal noise for a more 'aggressive' cam?
Had a few different cams in this car and have had the iPd turbo cam in here for well over a year. Initially didn't reshim because everything was verrry close to being in spec besides 1 or 2 on the loose side (but not excessive). Few months back I did some quick maths and ordered the shims I needed to make all clearances sit right around .016". Installed all new shims, everything was .015"-.017", so well within spec. Right after these new shims I noticed a far more audible valvetrain noise. Kinda just parked the car and worried about my other cars. I had second guessed myself and thought maybe the valves are still out of spec so I pulled the cam cover today and measured again Ever single clearances is between .014" and .018". I did not measure exact clearances but simply made sure they were all within spec. If I had to guess, I was right the first time and all clearances are hovering right at .016". Great! So why did this noise only show up after the new shims? Harder material than stock? Normal noise?
Please watch video in HD to hear it.
