DON'T DO IT! You will have trouble adjusting the valves the first time and then you will have trouble with the hydraulic lifters not staying full of oil, some will drain down and some won't. They will cause you trouble the rest of your life.
Adjusting your valves by hand every 3,000 miles is easy and can be done in 30 minutes or less. After a while it will become automatic. |

i take it you kno from expearnance, i kno you have to left them sit in a bucket of oil so they fill with oil over night i also kno that your sposted to crank the motor over by hand slowly for like 20min that way they get filled with oil..

Do the lifters go in the head, or down in the case?

We have a Mexi with a 1600 and hydraulic lifters. We have no problems, except if it sits for more than two weeks, it takes about three seconds for them to pump up...

|

I have built 18 - 20 hydraulic engines over the past 10 years, most of them are 1776cc. I also have three mexican beetles with hydraulic lifters.
This is the same setup that the vanagon Waserboxer used. There have never been any problems with them aside from if you leave them sit for long periods of time and even so they pump up relatively quickly. maybe 1 in 50 times drving one of them that has sat it will take 5 - 10 minutes before the noise goes away, same as the waserboxer used to do. I have switched the 1776 and all three mexi's over to Mobil Delvac 1 5w40 and havent had a tick in anything since.
The only reccomendation I have is use a new case as the lifter to case clearance is critical, and a full flow oil filter. I have been using VW-Mexico's factory hi volume filter oil pump exclusively and it works great.
The part number is BAA-115-101 and it is available from www.btlmex.com

| I have one lifter in my bug that will bleed off overnight but quites making noise after about 5 seconds, takes alittle longer after it sits a week or longer. I have been happy with the hydraulic lifters in my engine and have right at 100,000 miles on this engine. (Most of them are freeway miles) One thing I keep up on is oil changes and keeping it tuned up at all times. Being as an igniter is in it as well tune-ups are fairly easy. |

alright, well i'm planing on rebuilding my motor, what do i need to do this.. also how about a perf cam for these?
I plan on running a stock crank maybe a counterweitghted one
110 eagle cam
87mm(1641) slipins
and yes, a full flow kit

If you want hydraulic lifters I can only strongly reccomend a new case. If you want a 110 cam then you don't want hydraulic lifters. Also a 110 is not the bast match of you keep a stock carb. It prefers small duals.
You need a specific hydraulic grind cam, the ramps are different. I don't reccomend 87mm slip in's they are a little too thin wall for long term use.
I use a C/W crank in any non stock engine.

Wrong, in the early days of hydraulic lifters they would "pump up" full of oil and hold the valves open (float the valves) at high RPMs. This made solids the way to go for high RPM racing engines.
Todays lifters bleed down better.

i guess i just have no idea what function they serve, how they " work", and why they're "better".
i've been puzzling it over on my own, and they don't make sense to me. as far as "making" power;
1=as solid lifters have no "cushion" -ing hydraulic, they should transmit power to the valve train more directly and thereby forcefully thus increasing breathe-ability and thereby combustible mixture into the cylinder.....
2= this stuff i've been reading about clatter and sticking sounds like waqy more eventual and inevitable hassle than just adjusting the valves.
