Hydraulic Lifters

What are the merits of converting an engine to hydraulic valve lifters. Have seen some cars advertised with this mod on their motors???

Don't do it, even though you do eliminate valve adjustments, one spec of dirt in a lifter and said lifter will sound like Russian tap dancer, the only way to fix that it is split the case $$$$$ ~Alan

plus you have less selection in cams

Barry-

They're out there. Get out your check-book.

I would like to see some roller liffer conversions come avalible. That is well overdue.. I have noticed one thing..

The aluminum case engine, In my D can go longer between adjustments. The aluminum is more stable..Things dont change much over time..

You mean Jakes.. Id rather see something converted from production parts .. Your cost goes way down that way..

No- There;s a guy over on the Samba that converts AL bubble-top Autolinea cases to a roller set-up. I think his work on the case is something like $650, plus the cost of the lifters.

Regards the hydraulic lifters, I have had two engines with them. I like the "set and forget" valve adjustments for certain. Also, the engines lose the Singer sewing machine lifter noise, and that makes for a nicer sounding more quite engine....and Larry and Alan are very correct in that you need clean oil, you need to run a full flow oil filter system, and I have found that a higher capacity oil pump to work "better" also. There are certainly less cams available as stock items, the engines I have had were neither one "performance" engines, one was a 2109, the other was a 2275cc....but both were intended for fun street driving. All out performance? Stay away. Better street driving experience? I would certainly consider a hydraulic lifter engine again... my current engine has solid ceramic lifters.....

Stan that's not to awful a price. Does he do a type 4 conversion?
