Kosij Donating Members 2,045 Member For: 13y 8m 17d Gender: Male Posted 26/07/14 11:57 PM Share Posted 26/07/14 11:57 PM What would stuffed lifters cause?I notice when I do a big warm up burnout and stop straigjt away the car idles real rough for 30 seconds then comes fine again, sometimes it stalls and when I try and start it the car winds over with no compression like the spark plugs are missing...... Is this a sign of the lifter not keeping up? Link to comment https://www.fordxr6turbo.com/forum/topic/87188-lifters/page/2/#findComment-1487912 Share on other sites More sharing options...

If u do a wide open pull then go back to idle will it also happen Link to comment https://www.fordxr6turbo.com/forum/topic/87188-lifters/page/2/#findComment-1487915 Share on other sites More sharing options...

Definitely not springs Edited 27/07/14 01:13 AM by Kosij Link to comment https://www.fordxr6turbo.com/forum/topic/87188-lifters/page/2/#findComment-1487921 Share on other sites More sharing options...
turbotrana Member 2,586 Member For: 22y 28d Gender: Male Posted 27/07/14 01:40 AM Share Posted 27/07/14 01:40 AM Don't think you have stuffed lifters. Just looks like they pump up on high revs so when you go back to idle it takes a little time for them to bleed down so all the valves close properly.But having a higher bleed rate lifter may make the engine more clackity at idle. Talk to Atomic about it and tell us what you find out. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/87188-lifters/page/2/#findComment-1487926 Share on other sites More sharing options...

He mentioned lifters. It's a relatively now motor lol Link to comment https://www.fordxr6turbo.com/forum/topic/87188-lifters/page/2/#findComment-1487950 Share on other sites More sharing options...
