[TDC How to find it.]

Wow you guys are great! Those are really good ideas as well. I might acyually get this thing running today and have my first Pathy experience.

Umm, yeah. You are really looking for #1 TDC, the number one cylinder at top dead center, on the compression stroke. If you rotate the crank one rotation from there the number one cylinder will still be at the top, but this time on the exhaust stroke.

 

I don't have an R50, so I don't want to give specific advice really, but if it was me on my wd21 I'd probably pull a rocker cover or the upper timing cover. I guess you could also just wing it, because if you put the distributor in wrong then you won't be able to start the truck. But this will send unburnt fuel down your tailpipe. I exploded my muffler once by doing this.

 

 

That would be bad. I guess I need to pull a rocker cover and luckily the easiest one to do is the one with the No. 1. Might as well get it correct. Thanks a lot!

Crank pulley rotates twice for every complete 4-stroke cycle, so that isn't quite enough.

So TDC + 2 rotations = TDC?

I have a 1997 SE 4x4 3.3, I just swapped the engine from a 99 to it using most of the parts from the 97 attached to it. How do you find TDC if the distributor was never installed on it and do not want to pull the valve covers to look at the valves? I used the service manual to change the timing and everything seemed to work out as detailed but now I have had a thought about something. Would the mark on the crank pulley for TDC always indicate TDC or are there several revolutions of this mark to get to actual TDC?
