How do you know when these are bad? doing a cam swap soon and wondering if they are necessary? car has 100k with regular oil change (except one change went 4k, not 3k). Where can i buy OEM replacements. Only have an XE 224/230 so i dont need crazy lifters like the 306 needs. About how much are they?

 

When I did my cam swap, my engine had 75K miles on it. Shortly after the install, some of the lifters went bad. I highly suggest that u replace ur Lifters since u are 100K miles. I wouldn't waste ur money on OEM replacement lifters. U can get a nice set of Comp Cam Pro Magnum Lifters for only $10 more than stock.

I ordered my Lifters from www.cmotorsports.com With Overnight shipping the bill was only $233.22. Not too bad IMO.

 

for sure replace the lifters... might cost you more than you want to spend but will prolly save you time w/o having to go in and re-do them later when they do go bad. good luck

 

what about the lifters at Tbyrne.com theyre only 180.

 

you can do that or go to THUNDERRACING.COM and check out what they have

 

The ones for 180 are only OEM replacement lifters. Like I said, spend the extra $10 or $20 and get the Comp "R" Lifters, also known as the "Pro Magnums"

 

didnt know the 180 ones were OEM. thanks for the heads up man.
