jspecgallant Posted April 10, 2012 Report Share Posted April 10, 2012 Just wondering can I make a Mechnical head into a hydrolic head. Basicly take out the lifters, rocker arms and cam out of a head that was hydrolic and install the parts into a head that was originaly mechanical head. thanks Link to comment Share on other sites More sharing options...
Frenchi934 Posted April 10, 2012 Report Share Posted April 10, 2012 the heads are the same, but the lifters, and rocker tubes are different. I have a set of hyd lifters and tubes fs if you are interested Link to comment Share on other sites More sharing options...
jspecgallant Posted April 10, 2012 Author Report Share Posted April 10, 2012 the heads are the same, but the lifters, and rocker tubes are different. I have a set of hyd lifters and tubes fs if you are interested I have a hydrolic head with al the parts and was going to buy a head from a member - but the head he is trying to sell is mechanical. So does that mean i can take all my parts from the hydrolic head and install them to the mechanical head with no issues? Link to comment Share on other sites More sharing options...
Fanta Posted April 10, 2012 Report Share Posted April 10, 2012 Essentially, yes. But man, make darn sure your rocker assembly doesnt come apart. It's fun trying to figure out where what lifter goes where....... Link to comment Share on other sites More sharing options...

It's fun trying to figure out where what lifter goes where....... the lifters dont matter where they go? as long as you have the right tubes (with the correct size oil holes)?

Komeuppance Posted April 10, 2012 Report Share Posted April 10, 2012 Yeah, the lifters are all the same. You must use the hydraulic rocker shafts with hydraulic lifters. Here's a good tip on making sure the lifters are ready to go:Air and crap does get trapped in those lifters that chamber can't hold more than a drop or two of oil. If there's something in there trapped it could preventing the check ball from being able to seat and they will never pump up so just bleeding them might not do it. The chamber is a dead end hole and there's no way for it to flush out like in other type lifters. They can actually get full of crap and you can't clean them out and that crap as the engine is running damages the parts internally and you have to replace them. The air will pressurize and stay there and the lifter be squishy all the time and cause them to tick. If they are old they need washed just like any other old motor part and high mileage even with oil changes they still will eventually fill up and need washed out. If you had a new tight motor and rocker assembly and new lifters with air in them you might get them to stop but you aren't getting the oil pressure in the lifters like new parts would have its all leaking out at every crack. if you want to try and clean old ones here's Mitsubishis TSB how to:http://www.b2600turb...%20cleaning.pdfYou'd be surprised the crap that comes out of ones you know were working -Robert Link to comment Share on other sites More sharing options...
conquestTSIguy Posted April 10, 2012 Report Share Posted April 10, 2012 And make sure you use the same rocker caps that are currently on the head. Pretty much have to disassemble both sets of rockers and switch them over. Tubes, springs, rockers etc. Link to comment Share on other sites More sharing options...
Shelby Posted April 10, 2012 Report Share Posted April 10, 2012 make sure you do not try to simply swap entire assy's over even if they fit , you will have problems later on,, due to mismatch'd cam tower bearing caps , and in the end you'l distroy or make unuseable both heads Link to comment Share on other sites More sharing options...
Frenchi934 Posted April 10, 2012 Report Share Posted April 10, 2012 yes. as said before. you have to keep the cam caps with the respective head, but everything else associated with the lifters needs to be switched over to the other head Link to comment Share on other sites More sharing options...
techboy Posted April 12, 2012 Report Share Posted April 12, 2012 I love the search button, I was just going to ask this same question. Thanks for the info guys. Link to comment Share on other sites More sharing options...
Shelby Posted April 12, 2012 Report Share Posted April 12, 2012 precaution if your useing a non mits head be sure to check oil passages , a while back many aftermarket heads were found to not have enought oil flow for hyd rockers Link to comment Share on other sites More sharing options...
techboy Posted April 12, 2012 Report Share Posted April 12, 2012 I actually think I'm going to leave my mechanical head as is. NudeLobster has a Mitsu head he's going to sell me that I can use to build a hydralic. Link to comment Share on other sites More sharing options...
conquestTSIguy Posted April 12, 2012 Report Share Posted April 12, 2012 Personally I prefer a mechanical head. You get a little more chatter, but you don't have to worry about the lifters going flat either Link to comment Share on other sites More sharing options...
CaliConquestAlex Posted April 12, 2012 Report Share Posted April 12, 2012 I MUCH prefer the mechanical head. When I had a hydraulic head, I had terrible luck with the lifters and the engine always had a loud tick until it warmed up and the lifters got pumped up.
