My eclipse gsx with 272 cams
A short clip of my eclipse idling and a couple revs to 2k and 4k rpms. Open downpipe at the time, now I've got a turbo-back Exhaust.

4G63 Lifter installation without special tool part 2
In this segment I reinstall the rockers over the new lifters. Again, no special tools, or removal of the timing belt, cams, or cam caps. All we are doing here is putting the rockers back in place over fully bled aftermarket (topline) "3g" big hole lifters. These are NOT ebay lifters. I can't speak for them - I have never used them. *** Some side notes and related info*** -This car was purchased used with about 22k on it. They started ticking heavily about the third day after I bought it 2 years ago... and have ticked for about 20k more miles. -I recently switched from a 969400011 rom (05 rom) to a patched version of 96530006. Which must run different knock filters, as I had excessive part throttle knock I previously did not have. -Topline lifters stopped the part throttle knock -While they were pumping up and chattering, I couldn't even drive the car. I got repeated high knock counts to the point I could feel timing being pulled through the floor. -Once they filled up with oil and went silent I have NO knock. Even between gears, from stops, after a aggressive throttle then reapplication of throttle... Basically all the places I had knock before, I don't now. Which is great when it's this simple. Yay for lifters that don't tick.
