All of a sudden I got a huge loss of power, to the point I can hardly maintain 45 in 3rd gear on the flats. The valves tap like crazy under load and it will barly idle. Has this happened to anyone? If it is the t-chain will my timing read way off? Have yet to check fuel, compression or spark, but it starts every time just runs like $hit.

Thanks in advance...

If your timing chain jumped teeth, your timing marks will indeed be off by quite a bit, possibly so much that you will not see them. Sounds to me like it jumped a few teeth, and now your timing is retarded.

I may have the same problem... I just put a new head gasket on and I followed(from what I thought) the chelton book instructions properly. Everything whent back together OK, I had it at TDC and when putting the head back on I had the pin on the cam streight up when putting the chain gear back on... the problem I'm having is that it wont start and run when the timing mark is at 0*. but if I take the distrubitor and move it 180* the truck will start/run(rough) and the timing mark is now at the bottom???? I wasn't sure if the cam is 180* off or what???

89Yota,
When you put the motor at TDC, was it on the compression or exhaust stroke?

The way to tell is put it at TDC,pull the valve cover then check the rockers on cylinder 1. If they are LOOSE, and the rockers on cyl 4 are tight, you are on the correct stroke. (compression).

If the cyl 1 rockers are tight, and the cyl 4 rockers are loose, you are on the exhaust stroke. Rotate the crank one full turn (360*). Now you should be all set.


Some people can tell if they are on the correct stroke by pulling the #1 spark plug and sticking the tip of their pinky in the hole and feeling for the top of the piston.........

Oh yeah, BURN the Chilton's and get a Toyota FSM, or at leaast a Haynes.......

I already started the fire, I noticed some key steps they left out...

I didn't even think about which stroke it was set at... I'm hoping that's it, I never took the timing gear out of the chain...?!
Thanks a million <IMG SRC="smilies/beer.gif" border="0">

22re cam 180 out

i replaced my head and im not sure if my cam is 180 out. it was at tdc. it runs but it sounds like a diesel. and is it normal to get a large boost of power during mid range rpms.
