Engine Mechanical problem
1990 Toyota Celica 4 cyl Front Wheel Drive Manual

I started working on the engine of my vehicle because there was a leak under the timing belt cover. I took apart the water pump pulley, timing belt, oil pump body and body cover. I replaced all gaskets. While installing everything back together and starting up the car I noticed that the engine wasn't running smooth. It sounded like a skipping sound, plus from the exhaust the was white smoke. When I looked at the spark plug there was some oil, possibly water mixed in as well. Please could anyone help me with this situation. Another thing I have to ask, say if I didn't put the timing belt on exactly as I took it off, could that also be the situation?

It is critical that the valve timing is set correctly, check the pics for correct alignment, start here.

Okay thanks for the heads up on the alignment. One more thing please, if I align the camshaft sprocket and the crankshaft at ATDC. How do I Install the new timing belt that I bought? Can it just go on anyway? Or is there a certain mark on the belt to align?Another thing also say if I have white smoke coming out the muffler, even though I only started the engine twice. I am sure that the head gasket wasn't the problem. I know there is oil in the pistons, I am planning on using Sea Foam to clear it out. Please help me with info on getting my new timing belt on even if I do not have any markings on the old one. Thank you so much for the help I'm willing to support

Hi there,

The position of the timing belt in relationship to the gears is not important, as feed the belt from the crank shaft, over the can then around the tensioner, as long as the gear timing marks are aligned and there is no slack in the long side, I.E crank to cam, not cam idler crank, this sis what you are looking for, with the tensioner set, spring tension only do not lever, gears must be aligned as per last pic.
