I am thinking of putting the stock cams back in the car tomorrow, never done it before, and was wondering how you identify which cam is intake and which is exhaust?

that makes it easy. And is it really necessary to bleed off the lifters prior to putting it all back together?

I don't know much about bleeding them, but I absolutely did. It's really not hard at all, just read the vfaq and you will have no problem. The hard part is not breaking the paperclip off in there if you don't have 3g lifters. I broke one off in there and thank god it didn't go all the way inside and I was able to get it out with a magnet.

Quoting deez:

Yes.

Unless... You turn the crank 90º from tdc so all the pistons are halfway up/down the bores, then fit the cams, tighten the cam caps, then leave it overnight. In the morning turn the crank back 90º to tdc and install the timing belts as normal.

Just pull the belt off and reset the timing mark at the crank, check the cam gears for their marks both across the head horizontally and make sure they are parallel vertically(the correct top* of the gear is up) and put the belt on with the slack on the exhuast side, where the tentioner can tighten it up.
You got it

This just never works on mitsus. they have a "special" tool to screw into the cover that compresses the hydraulic tensioner that would allow you to do it that way but I just never try it, to risky with a mitsu twin cam of any series, they always end up off.



How do you make a small fortune racing? Start with a very large one!!!

Odd. I've never had any problem getting the timing belt on properly. I don't see how anyone could have such a problem with it.

Did you lock the hydraulic tensioner before removing the cambelt from the cam gears?

The tentioner pulley must be tight, before you pull the pin on your tentioner. The two pin holes on the outside of the pulley, should be at 11 and 1 oclock, To at least get it good and tight. If, your balance shafts are out you dont have to line that up at all. Idk Make sure both cams can even line up, you might have to turn just one cam before you put it at tdc.
