after noon to all . some time ago under a shade tree far far away i did an engine swap on a 94 T4R SR 5 . i took the 3.0 with the blown head gasket out and i put another 3.0 in and all was good in the land . now last Thursday my wonderful wife angered the t4r and it obliterated the timing belt in to something that now looks like some sort of demonic pasta . so i tear it apart clean it all up and put it all back together . and here is the problem i cant get the cams to stay in time with the crank . i have no idea what i'm doing wrong . plus my right cam seems to have compression on it when i turn it where the left came does not . so if any body has some insight in to this please let me know . thanks

... I'm sorry, I'm still trying to find the reasoning behind the title of this thread...


I'm no 3.0 specialist, but if it were a 22re I'd just say that your crank and cam is still out of alignment during the install... maybe you were not at #1 TDC when you though you were


maybe this bump will bring this thread to someone else's attention who may have some more useful info than me

You need to make sure you get all of the slack in the area where the tensioner is, between the passenger side cam sprocket and the crank pulley.

It is best with two people, four hands.

Set the crank at the TDC indicator, just line up the mark on the crank pulley with the mark. Line up the two cam sprockets with the marks on the sheetmeal backing plate. One of them will be very unstable when it is on the mark, it will want to fall off the mark either way, due to unbalanced forces from the valve springs on several of the lobes. That is the one that the extra hands comes in really handy.

Start at the crank with the belt. Pull it really tight up and around the water pump pullley, then up to the driver's side cam sprocket. Have your helper keep that sprocket in place while you keep tension on the belt and engage it with the teeth on the sprocket. Then feed it around the idler pulley, and engage the passenger side sprocket. This is all done with an eye towards getting it as tight as possible. You then let the tensioner off to do it's job. Rotate it through two revolutions, see if it is aligned. If you keep getting off by a tooth, then, preset the cams back a tooth in the opposite direction and do the same install procudure, they will fall into alignment.

Good luck.
