How to set the timing on a 91 acura legend - 1991 Acura Legend
Ok i got a 91 Legend. The repair manual says to lock the two cams in TDC. So find the blue driver side and red passenger side timing marks on the sprockets facing towards front. Thers a notch yellow lineat about 11 o'clock on the driver side and 1 o'clock on the passenger. line them up and find something to keep them in place. If they move you could have a valve bent by a cylinder so dont force it to much. When moving the sprockets you need to have the crank/oil pump gasket/harmonic balance r pointing up. theres a small arrow on the engine if you have your timing covers off that you line up with a little dimple tiny mak( you might have to remove the crank pully and behind it is the timing pully its half the size of the sprokets and rotates twice for every sproket thet turn. so make sure you keep thing fastened so you can save a lil time. line up the marks on the crank. not totaly sure but i think the front passenger side cylinder is the #1. Just start on the crank then by the tensioner, then driver or left cam, then whater pump then finally the passenger side cam. this one tends to move then when you try and TDC it swing with spring lifter or valve action. Move the passenger cam one tooth advanced clock wise. Clock wise is how a legend engine shoul be turned. If you dont advance the passenger cam a tooth the timing will most likly be one tooth off. This a little trick to put on perfect timing. After you turne the crak six times making sure on every turn that TDC marks line up, if not start over. when all is good you turn the crank nine teeth clock wise. every thing like the timing cover should be on now. locate the marks or three noches they should line up to a blue line on the crank pully. Oh i forget you can take the spark plugs out to help turn the the engine. oh you could also use an air compressor in the spark plugs to lift a valve or something if it falls on a piston. You will need 19mm socket a ether home made tool or the holder tool( ebay $25) or ( home depo 11/2 galvined pipe with hexagon shape $12.50). Alsow a 10mm, 5/16 or actually 8mm and 12mm. Thats all of the top of my head. Well i just did it few days ago. Good luck and if you have the time and the tools of confidence save your self a few weeks pay but if something aint right stop recheck or you might need to losen the rocker arms in the engine their 8mm and six up in there and keep the screews on lose lift entire rocker assembly. two turns at a time on every bolt till there all lose fift as unit be care full or it can fall a part in few dozen pieces. This may only need to be done if you have something hitting and the air wont put it in place. Peace
