where do you bleed the oil from the hydraulic lifters. can't figure it out. thanks nick

 

www.evomoto.com goto evo-tech section and follow their directions

 

i didnt see anything about bleeding the lifters in the evomoto cam install write up maybe i missed it somewhere?

 

same here! is it necessary???

 

well if you have a noticible tick, like i do, i have heard to bleed the lifters and alot of the noise will go away. i was planning on doing this tomorrow. i already have a good idea of how to do it so it shouldnt be a problem

 

You need to put a pin (paper clip) down the center of the lifter to unseat the check ball. Pish in on the center of the piston to push out the oil. Push in and out on the piston until it moves a good distance without the pin.

Best tool for the pin is a CDROM drive ejector pin you get with Plextor drives.
Don't over do it with the pin pressure and don't reassemble without doing all of them, you will damage a lash adjuster.

 

Before you take it apart you may want to push down on all the lifters to see if you can push any of them in. Most likely an intake lifter will be the culprit and if you can push it in you will need to replace it. So unless you have another car you'll have to put the cover back on and go get one first.

 

i thought you just pulled the lifters bled them with a paperclip and reinstalled them, how do you know if you need a new one?

 

Vishnu has a specific procedure on doing this, it ha something to do with revving your engine slowly up to like 3k or something, call them and ask or do a search

 

i saw their method, but i am trying to understand what you said earlier to see if you can push down any lifters? so if i can push on a lifter while its still in the motor and it moves it needs to be replaced?

 

IF you don't need the pin to push the piston in then the lash adjuster is dead.
Here's the problem. You remove the cams and the lash adjusters extend themselves fully.
You don't bleed the oil out and put the cams back in. First that is not good for the cam caps to have to push the cam back down with no give except the valve spring. Second you removed a low lift cam where the the lash adjusters were not extended all the way and were nice and quiet. Now they are fully extended and you installed a cam with considerably more lift. The force of the intake cam which rotates towards the lash adjuster will blow out the seal inside. Doesn't always happen but there is a good chance it has.

This is why I told you to try and push them in before disassembly. They don't move so if one is bad you will know it.

 

thanks for all the help

 

Bump for ppl who needs help on this topic. Now I am VERY confident in installing cams except for the timing part. That I'm a lil nervous

 

Dude, i was freakin out too about the timing, but it's not as bad as u think. The only real trouble i had with the install was breakin the cam bolts loose and taking over the cam bearings. As long as u follow the evo moto guide, u shouldn't have any problems whatsoever. Good luck!
