Hydraulic lifters
Is it possible to have a 1.8 liter motor converted to run hydraulic lifters? If so, what are the negative sides to the conversion besides price?

Go see my site, at www.aircooledtechnology.com and look under the FAQ...
For numerous reasons, keep it solid..adjusting valves in a 914, really sucks, but not half as bad as the damage that they can cause.. I see it ALL THE TIME, while many books and some others in the business may disagree, take my word for it.. To take maintenance from an aircooled engines valve train, is equal to setting a grenade in the valve cover.. |

We have hydraulic lifters in our 2l 914 and have had no troubles in the greater than 2 years we have had it. Since it has a stock FI system we don't rev it to much over 5800 RPM so have had no lifter problems. The only thing I have noticed is if the car sits for several days they clatter a little until they get pumped up. ours is a complete Web cam setup and the case was modified for increased oil to the lifter galleries. I would recommend talking to the shop(s) in your area that might be doing your work and get their opinions and you will see here there are many against and many for their use. Make sure they use all the parts. Good luck.

Many problems with Hydraulic cams, are not apparent. I know of alot of type 4 engines with stock, hydros, After 40-50,000 milkes the cam is wiped out..Solid lift cams have 3 times that amount of life, in most cases.
If you have hydros, change the oil more frequently, pop those valve covers off, even if you don't need to, and keep a spare hydro lifter in the glovebox, just in case one of them decides to explode on your next road trip. Jake Raby Raby's Aircooled Technology www.aircooledtechnology.com |

I have a 74 1.8L with FI and it came with hydraulic lifters. The only problem I have is if I dont run it for a couple of weeks they bleed down and it takes about 20 min until they all pump up.It bangs and misses pretty bad but If I run it every week it great. I dont think they are meant to be horizontal.

It did not come FACTORY with Hydro lifters....
The pumping up problem is another reason why I refuse to build hydro engines.. All that beating and clanking is murder on the valve train, and has been known to loosen valve seats, to help them drop...That jackhammer action can be a real killer, if you have a tired valve, that is ready to have a jousting match with a piston. |

The late 70's GE and later cases had hydros. Maybe use one of those blocks with a modified dipstick would work?
