Hydraulic Lifter Leaking Down

Caught a hydraulic lifter starting to go bad on my turbo coupe. Cylinder 4 exhaust to be exact. Came out of know where, caught it before any damage occurred. Since the Camshaft has to come out and I will more then likely replace all the lifters (looks pricey), I cant figure out what all I would need for a roller cam conversion. I've seen two cam options people talk about, Ranger Roller and A237. I also know that you need roller followers. Do you use the same style lifters with the roller cam? Lastly, Esslinger sells parts and so does Big R Motorsports, just curious if anyone has any experience with either.

Yes you can use the same lifters from your flat cam to use a roller cam. I have purchased a few different items from Big R, good vendor, easy to work with. He also has his own Ranger roller regrinds that would work better with a turbo than the old A237. He also usually has sets of roller lifters to buy. Also, if you only want to change the lifters I'm pretty sure if you remove the rockers the lifters will come right out without removing the cam. This way you can simply replace the lifters and keep your flat cam and rockers.

Yes, cam doesn't need to come out... I know I did lifters a while ago (8+ years), I believe I used some sort of tool to compress the spring and didn't remove the rockers.  I'll look later today for it and update.

I’ll probably end up just going after the lifters for now. Going to the roller cam is tempting though.
