22RE TDC How?

[prodigy2k7]

My timing chain jumped a tooth so, how do I make the timing correct when I replace the timing chain?

I hear the crank is supossed to be 6:00 down and the cam is 12:00 straight up.

I am so confused. What do I need to do to set the timing correct when I put the chain on?

TDC: How do I get it exactly on TDC, I can seem to get somewhat close like 10:00 or 2:00 but never 12:00 the engine just never stops there.

Help please!!!

A simple way is to pull all the plugs, block off the #1 plug hole with your thumb, and turn the crankshaft by hand using a wrench on the nut.

Once you feel pressure on your thumb cyl #1 is in the compression stroke.

Remove your thumb a stick a wooden dowel into the plug hole, and slowly crank by hand until the dowel sticks out the most.

Cranking back and forth and some reference marks penciled onto the dowel will help find that max point, which is TDC.

IF YOU DO THE DOWEL TRICK BE EXTREMELY CAREFUL! I tried this yesterday morning and the dowel broke inside my cylinder thus beginning the most difficult, shame-ridden struggle of a day, involving over $100 worth of new tools tools (6hp shop vac, long narrow tweezers, a mechanical hand, and various lighting implements). I won't have any way of knowing whether it's all out until I put everything back together and turn my car on. This is the chance I'm taking because I don't want to take my head off. Be extremely careful any time you take a spark plug out; shrapnel in a cylinder will cause major problems. In retrospect, I WISH I had simply turned the crank and used my eyes. The reason I wasn't sure about TDC is that there are three different marks on my crank shaft that various sources said were TDC. If I had simply looked in the no. 1 cylinder with a flash light while slowly scooting the crank around, I would have been able to get really close using my eyes, and moved to the nearest clear TDC mark on the crank with confidence that I'd ruled out the other two, which are visually less close to TDC. I totally regret using the dowel method. Just my $.02.
